Description

WASTEWATER RECOVERY AND TECHNOLOGICAL TREATMENT SYSTEM Technical Field
The present invention relates to a treatment system that is used in the treatment of wastes discarded after the completion of processes carried out in such fields as textile, food, heavy industry, paper industry, glass industry, etc., and in water recovery as well. in particular, the Invention relates to a wastewater recovery and technological treatment system that enables a high-efficiency and sustainable recovery of the wastewater stemming from a process carried out in industrial plants without using chemical agents and by eliminating the drawback of waste release to the environment and that also helps operational costs to be reduced.
Prior Art Water usage in the industry has immensely gained importance in recent years regarding both the quality of the water used and environmental outcomes of the wastes emerged as well. Particularly, in industrial sectors such as textile, paper, plastic, glass, metal, food, large quantifies of high-quality water is used in manufacturing processes of the plants, whiiehigh volume wastewater containing many chemical agents occurs.
In the current art, in the textile industry and other industrial plants, wastewater can be gained into reuse through recovery systems such as jacketed heating, electrocoagulation, and osmosis system while it is possible to subject the wastewater to biological and/or chemical treatment processes after use and then to introduce it into sewers.
Jacketed heating systems, which are one of the most prevalently used systems in the current applications, are generally systems that operate by vaporizing the wastewater contained in itself through the method of steam-heating. These systems consume a large amount of energy and have high installation costs. Furthermore, as they perform the recovery process at high temperatures, their cooling capacity is not sufficient. Therefore, the desired efficiency cannot be achieved in the system. In the electrocoagulation system, which is another commonly used system, a plurality of iron plates are used as being positioned parallel to one another. Said plates are provided with poles through which wastewater is allowed to be passed

between the plates. The wastewater passing through the plates is ionizated and impurities rises to the upper surface of the wastewater. Chemical and osmosis systems are used in the next processes in order in order to

wastewater to be reused. The drawback of these systems is the need for replacing the plates in very short periods. The piates incrementally fade out and become unserviceable as the required processes are carried out. In this system that operates by introducing electricity to the plates, high energy costs are a matter of concern. Chemicals are used in order in order to enable the water recovered to be reused. Such usage of chemicals also leads to additional costs and workloads. Furthermore, to be able to use the recovered water, the osmosis system is later required. This system also causes establishments to encounter the problem of extra cost and high energy consumption. Accordingly, recovery systems are not preferable due to their drawbacks of high installation and operational cost, low efficiency, and the requirement for using chemicals during processes. Therefore, in wastewater recovery, only biological treatment and draining into sewers are preferred. This nevertheless causes environmental pollution and serious disorders in living creatures. Thus, since current systems are not capable of meeting expectations and greater masses of wafer are required to be treated although industrial wastewater recovery is now becoming more common, it has recently been mandatory to develop novel treatment technologies that occupy a narrower area, apply to all types of wastewater, economical and quite efficient regarding effluent quality.

Said document is related to an osmotic-assisted desalination system and a method thereof, Insaid invention, a system and a method, a system and method using a pressure purification process such as reverse osmosis in conjunction with a pressure delayed osmosis subsystem to provide desalination of low or high concentration brine from the sea, ocean or a similar body of water is mentioned.

Therefore, with said system and method, it is not possible in order to enable the wastewater formed from manufacturing processes in plants to be recovered.

Detailed Description of the Invention
In this detailed description, preferred alternative embodiments of the treatment system subject to the invention have been described, without any limitations, only in order to enable the subject matter to be better understood.
In Figure 1, a top view of the treatment system subject to the invention is illustrated. Accordingly, the treatment system basically comprises; a plant wastewater storage tank (1) in which the wastewater formed as a result of manufacturing processes in an industrial plant is contained, a dielectric sterilization system (5) that performs a
Figure imgf000009_0001
sterilization process by disinfecting the water sucked out of the plant wastewater storage tank (1), a pre-filtration system (7) that filters particles contained in the wastewater disinfected in the dielectric sterilization system (5), a filtered wastewater basin (12) in which the wastewater filtered in the pre-filtration system (7) is contained, a main unit (15) that stores the wastewater stored in the wastewater basin (12) through the vacuum obtained by means of a vacuum pump (13), a dielectric heating tube (29) that vaporizes the wastewater stored in the main unit (15) by heating with a dielectric fieldvia the capacitors, a horizontal heat exchanger (19) comprised of a vertical body having thereon pipe bundles that perform a pre-cooling process to the steam extracted out of the main unit (15) through vacuum and a pre- heating process to the wastewater that passes therethrough and is introduced to the main unit (15) in order to be heated, a vertical heat exchanger (20) comprised of a vertical body having thereon pipe bundles that enable the steam subjected to pre cooling in the horizontal heat exchanger (19) to be distilled, a distilled water reservoir (32) that enables the water distilled in the vertical heat exchanger (20) to be stored in order to be transferred to the plant water storage tank, a waste sludge discharge line (30) that discharges the waste sludge remaining in the main unit (15) during the vaporizing process, a washing ball (34) that automatically cleanse the waste sludge in the main unit (15).
In the treatment system having overall perspective views in Figures 2 and 3, the wastewater formed as a result of manufacturing processes in an industrial plant is stored in the plant wastewater storage tank (1). Plant wastewater storage tank (1) is connected to at least one wastewater suction line (2) and thus enables the wastewater contained in the plant wastewater storage tank (1) to be sucked into the treatment system through at least one wastewater suction pump (3).
The wastewater suction pump (3) is firstly connected to the wastewater sterilization system suction line (4) in an effort in order to enable the wastewater sucked out of the wastewater suction pump (3) to be disinfected, thereby enabling the wastewater to be transferred to the dielectric sterilization system (5). Said dielectric sterilization system (5) is basically comprised of the profiles that are operated through the capacitors placed within the electrical automation panel (27) in which the automation of the treatment system is provided, and that are interlocked to expose the wastewater to the dielectric field. Thus, the wastewater passed through the wastewater sterilization system suction line (4) is subjected to pre-sterilization process by means of the dielectric sterilization system (5) and thereby enabling the wastewater to be disinfected and ready to be filtered.
The wastewater treated with the pre-sterilization process in the dielectric sterilization system (5) is passed to the pre-filtration system (7) through the wastewater
Figure imgf000010_0001
filtration system suction line (6) connected to the dielectric sterilization system (5). The pre-filtration system (7) enables the sterilized wastewater to be made ready for the process by removing solid particles contained in the wastewater. Said
Figure imgf000010_0002
filtration system (7) has stainless wire gauze filters of different micron diameters in a through-narrowing form and is basically comprised of at least 7 groups in 3 individual lines that are positioned on the pre-filtration system chassis (8). Thus, the wastewater is enabled to be cleaned from solid materials as it passes through the pre-filtration system (7). Solid particles retained in the pre-filtration system (7) are introduced to a sewer of the plant or, if provided in the plant, to a sludge drying machine through the
Figure imgf000011_0001
filtration system outlet line (10) that is connected to the pre-filtration system (7). The pre-filtration system sludge outlet line valve (11) is also connected to the pre-filtration system (7), and thus solid particles filling inside of the pre-filtration system (7) are enabled to be automatically introduced to said sewer or sludge drying machine.
The wastewater cleaned out of solid particles in the pre-filtration system (7) is transferred to the filtered wastewater basin (12) through the pre-filtration system outlet line (9) connected to the pre-filtration system (7) and then is stored in the filtered wastewater basin (12).
The wastewater that is stored in the filtered wastewater basin (12) after being treated with pre-sterilization and pre-filtration processes is distributed to the filtered wastewater horizontal heat exchanger inlet collectors (17) by means of the filtered wastewater collector suction line (16) connected to the filtered wastewater basin (12). The wastewater distributed to the filtered wastewater horizontal heat exchanger inlet collectors (17) is introduced to the horizontal heat exchangers (19) through the suction line to the filtered wastewater horizontal heat exchanger (18). Said filtered wastewater collector suction line (16) provides a connection between the filtered wastewater basin (12) and the filtered wastewater horizontal heat exchanger inlet collectors (17) and thus enables the wastewater stored in the wastewater basin (12) to be distributed to the filtered wastewater horizontal heat exchanger inlet collectors (17). The filtered wastewater horizontal heat exchanger inlet collectors (17) are connected between the filtered wastewater collector suction line (16) and the suction line to the filtered wastewater horizontal heat exchanger (18). The suction line to the filtered wastewater horizontal heat exchanger (18) provides a connection between the filtered wastewater horizontal heat exchanger inlet collectors (17) and the horizontal heat exchangers (19) and thereby enabling the wastewater distributed to the filtered wastewater horizontal heat exchanger inlet collectors (17) to be introduced to each horizontal heat exchanger (19). The wastewater passing through the horizontal heat exchangers (19) passes through the wastewater horizontal heat exchanger outlet line (28) connected to the horizontal heat exchangers (19) and fills into the main unit (15) that forms the main structure of the treatment system. Said main unit (15) is the component in which the wastewater is stored to be vaporized by being heated up. The main unit (15) is kept under vacuum by means of the vacuum pump (13) through which it is connected to the vacuum pump suction line (14). Thus, the main unit (15) is enabled to perform vaporizing at low temperatures under a vacuum.
The amount of the water that is stored in the main unit (15) is controlled by means of adjustment sensors located in the main unit (15), and when the amount of water in the main unit (15) reaches the maximum level, wastewater intake to the main unit (15) is stopped and the process of vaporizing is initiated. When the amount of wastewater in the main unit (15) reaches back to the minimum level, water intake is restarted. During the vaporizing process in the main unit (15), waste sludge starts to gather.At least one sludge sensor is placed in the main unit (15) for detaching if this waste sludge reaches the maximum level in the main unit (15), and as shown in Figure 4, to discharge said sludge from the main unit (15), at least one waste sludge discharge line (30) is connected under the main unit (15) and the waste sludge discharge pump (31) is connected to the waste sludge discharge line (30). When the waste sludge in the main unit (15) reaches the maximum level, the sludge sensor detects it and the waste sludge is extracted by means of the waste sludge discharge pump (31) and is discharged through the waste sludge discharge line (30).
The washing ball (34) is thereon coupled with the main unit (15) to automatically clean the main unit (15). After the waste sludge in the main unit (15) is discharged, said washing ball (34) cleans the main unit automatically.
The process of vaporizing the wastewater stored in the main unit (15) by being heated up is performed by means of the dielectric heating tubes (29) that provides heating with a dielectric field by operating in conjunction with the capacitors located in the electrical automation panel (27) through which the automation of the treatment system is provided.
The steam obtained by means of the dielectric heating tubes (29) in the main unit (15) is introduced to the horizontal heat exchangers (19) by being vacuumed through the vacuum pump (13). Said horizontal heat exchangers (19) are consisting of a vertical body having pipe bundles therein. The steam obtained in the main unit (15) passes through the pipe bundles of the horizontal heat exchangers (19) while the wastewater introduced to the main unit (15) from the wastewater basin (12) passes through the body outside the pipe bundles. Accordingly, the steam passing through the pipe bundles interferes with the wastewater passing outside the pipe bundles and thus a heat exchange occurs in the horizontal heat exchangers (19). Thus, the wastewater introduced to the main unit (15) from the wastewater basin (12) is enabled to be subjected to pre-heating process with the effect of the steam obtained in the main unit (15) during the wastewater passes outside the pipe bundles as well as a pre-cooling process with the effect of the wastewater introduced to the main unit (15) from the wastewater basin (12) during the steam obtained in the main unit (15) passes through the pipe bundles. The steam-subjected to pre-cooling process in the horizontal heat exchange (19) passes to the vertical heat exchanger (20) that is consisting of a vertical body having pipe bundles therein and enables the steam to be distilled. The process of distilling in said vertical heat exchanger (20) is performed with the cooling water passing through the body outside the pipe bundles during the steam passes through the pipe bundles. To feed cooling water into the vertical heat exchanger (20) is performed by means of cooling water that enters the plant cold water line (38) and is distributed by the cold water collectors (35), and passes through the heat exchanger cold water intake line (33) connected to the vertical heat exchangers (20). The water heated up by interfering with the steam in the vertical heat exchangers (20) exits the vertical heat exchangers (20) through the vertical cooling heat exchanger hot water outlet line (36) by being extracted with air through the vacuum pump suction line (14) and fills into the vacuum pump service water discharge vessel (22) by being connected to the vertical cooling heat exchanger hot water outlet collectors (37) communicated with the vertical cooling heat exchanger hot water outlet line (36).
The vacuum pump service water discharge vessel (22) has a level sensor that detects the occupancy rate of the cooling water extracted with air through the vacuum pump suction line (14) and of the vacuum pump (13) service water in the vessel. The discharge vessel service water suction pump (24) is connected to the vacuum pump service water discharge vessel (22) by means of the discharge vessel service water discharge line (23). The maximum amount of water in the vacuum pump service water discharge vessel (22) is detected through said level sensors, and the excess water is automatically transferred to the plant storage tank over the service water discharge line (25) through the discharge vessel service water suction pump (24) depending on the occupancy rate.
The water distilled in the vertical heat exchangers (20) fills in the distilled water reservoir (32) located under the vertical heat exchangers (20) to be used in the plant. The distilled water reservoir (32) has thereon-level sensors that detect the level of water. Additionally, the subvacuum pump (21) is connected to the distilled water reservoir (32). Level sensors detect when the water amount in the distilled water reservoir (32) reaches the maximum level through the level sensors and the excess water is transferred to the plant storage tank through the subvacuum pump (21) in order to be used in the plant.
Operation principle of the treatment system subject to the invention is as the following;
The wastewater formed as a result of manufacturing processes in an industrial plant is stored in the plant wastewater storage tank (1). The wastewater contained in the plant wastewater storage tank (1) is sucked through the wastewater suction pump (3), and the wastewater is passed through the wastewater sterilization system suction line (4) and is transferred to the dielectric sterilization system (5). The wastewater subjected to the dielectric field created in the dielectric sterilization system (5) is disinfected.
The wastewater subjected to pre-sterilization process in the dielectric sterilization system (5) is introduced to the pre-filtration system (7) through the wastewater
Figure imgf000014_0001
filtration system suction line (6) connected to the dielectric sterilization system (5). Solid particles retained in the pre-filtration system (7) are introduced to a sewer of the plant or, if provided in the plant, to a sludge drying machine through the
Figure imgf000014_0002
filtration system outlet line (10) that is connected to the pre-filtration system (7).
The wastewater cleaned out of solid particles in the pre-filtration system (7) is stored in the filtered wastewater basin (12) through the pre-filtration system outlet line (9).
The main unit (15) is kept under vacuum by means of the vacuum pump (13) and the wastewater stored in the filtered wastewater basin (12) is sucked and distributed to the filtered wastewater horizontal heat exchanger inlet collectors (17) by means of the filtered wastewater collector suction line (16). The wastewater distributed to the filtered wastewater horizontal heat exchanger inlet collectors (17) is introduced to the horizontal heat exchangers (19) through the suction line to the filtered wastewater horizontal heat exchanger (18).
The wastewater passing through the horizontal heat exchangers (19) fills in the main unit (15) by passing through the horizontal heat exchanger outlet line (28). When the main unit (15) reaches the determined level of filling, the process of filling is completed and suction of the wastewater is stopped.
The capacitors located in the electrical automation panel (27) transfers power to the dielectric heating tubes (29). The wastewater contained in the main unit (15) is heated up and vaporized with the dielectric field created in each dielectric heating tube (29), and is introduced to the horizontal heat exchangers (19) by being extracted through the vacuum. At this point, the steam obtained in the main unit (15) passes through the pipe bundles of the horizontal heat exchangers (19) while the wastewater introduced to the main unit (15) from the wastewater basin (12) passes through the body outside the pipe bundles. Thus, the steam passing through the pipe bundles interferes with the wastewater passing outside the pipe bundles, and a
Figure imgf000015_0001
cooling process to the steam as well as a pre-heating process to the wastewater introduced to the main unit (15) is applied by performing a heat transfer in the horizontal heat exchangers (19). The steam-treated with the pre-cooling process in the horizontal heat exchangers (19) passes to the vertical heat exchangers (20). The steam in the vertical heat exchangers (20), while passing through the pipe bundles of the vertical heat exchangers (20), is cooled with the cooling water passing through the body of the vertical heat exchangers (20) outside the pipe bundles and thus is distilled.
The water distilled in the vertical heat exchangers (20) fills in the distilled water reservoir (32) located under the vertical heat exchangers (20) in order to be used in the plant. When the water amount in the distilled water reservoir (32) reaches the maximum level, the distilled water is transferred to the plant water storage tank through the subvacuum pump (21 ) in order to be used in the plant. The cooling water that is heated up during the distilling process in the vertical heat exchangers (20), and the vacuum pump (13) service water exit the vertical heat exchangers (20) through the vertical cooling heat exchanger hot water outlet line (36) by being extracted together with air through the vacuum pump suction line (14) and, fill in the vacuum pump service water discharge vessel (22) by being connected to the vertical cooling heat exchanger hot outlet collectors (37) communicated with the vertical cooling heat exchanger hot water outlet line (36). The water contained in the vacuum pump service water discharge vessel (22) is automatically transferred to the plant storage tank over the service water discharge line (25) through the discharge vessel service water suction pump (24).
The sludge sensor detects when the waste sludge reaches the maximum level in the main unit (15) and wastewater intake to the main unit (15) is stopped. The waste sludge in the main unit (15) is extracted by means of the waste sludge discharge pump (31) and is discharged through the waste sludge discharge line (30). After the waste sludge in the main unit (15) is discharged, the main unit (15) is automatically cleaned by means of the washing ball (34).
