Description

A FLOATING WASTE WATER TREATMENT FACILITY FOR DISPOSAL OF MARINE DEBRIS AT SOURCE

Technical Field:

This invention is related to a floating waste water treatment facility for disposal of marine debris at source which provides a solution for all of the stages of accepting, storing, carrying to disposal facilities and treating ship sourced waste water at once and at the same point and allows for recording and concurrently monitoring the entire procedure of waste treatment.

Prior Art:

A ship means all kinds of types and structures of marine vehicles such as all sea crafts, hovercrafts, hydrophilic boats, platforms and submarines which can navigate at the sea and inland waters with a device other than a paddle, irrespective of its intended use. As can be understood from its meaning, building a ship which is a sea craft, using it in marine trade and moving it at the sea are subject to certain national and international regulations. One of the most important of these international regulations is the MARPOL 73/78 convention on the rules for preventing of marine pollution from ships that navigate at the sea. Our country became a party to the International Convention for the Prevention of Pollution From Ships (MARPOL 73/78) on June 24, 1990. The MARPOL 73/78 Convention covers 150 gross tone and all larger ships that navigate at national and international waters.

Ship sourced marine pollution is one of the crucial environmental problems pending for a solution today. Generation of solid waste and waste water at ships can vary depending on the ship structure, machinery equipment, running time of the ship, fuel consumption, number of people at the ship and the load it carries and increases in direct proportion. Ship sourced solid waste and waste water can be defined in two categories. The first category is the solid waste and waste water generated by operational and vital functions caused by the navigation of the ship. The other category is the solid waste and waste water generated at ports and during navigation caused by the load the ship carries. Disposal of solid waste and waste water generated at ships can be in two ways. The first method is discharging solid waste and waste water to coastal waste treatment facilities while the ship is at the port according to MARPOL 73/78 and the waste discharge regulations applicable in the country it is located in. The second method is not applicable for all kinds of solid waste and waste water, it is only applicable for bilge water, some combustible solid waste, compostable food waste etc. specifically described in MARPOL 73/78. Using composters for separator (separates oily water), incinerator (burns solid waste) and cuisine waste as described in the certificates issued by international classification organizations within the limits set forth in MARPOL 73/78 is another method of disposal of solid waste and waste water at ships.

In prior art, ships are required to come ashore and wait there for a while in treating and disposing solid waste and waste water generated at ships. However, this situation causes loss of time and problems with conducting necessary monitoring to maintain cleanliness of the sea.

Purpose of Invention:

This invention to be registered intends to allow for disposal of marine debris at source and prevent marine pollution caused by sea vehicles at coasts and bays in Turkey at source.

Description of Invention:

This invention fulfills its function by the operation of multiple main units together. The invention comprises a waste water treatment system which is integrated on and inside the pontoon that is a sea surface vehicle, and necessary auxiliary units for the functioning of the system.

The invention is mainly used in municipal waste water treatment. It can also accept and treat different waste waters through the modification of the units as required. The invention has the capacity that can treat varying volumes of municipal wastes.

The invention, basically a floating main carrier, comprises the main units of a equalization tank (1.1) that automatically keeps the floating main carrier on the sea surface depending on the waste water it accepts, a treated water tank (1.5), at least one membrane bioreactor (MBR) tank (1.3) embedded in the floating structure, an electric generator (1.4) for operation of the invention on 24 hour basis and a fuel tank, a sludge unit (1.6) where solid residues which are generated after treatment and called “Sludge” are collected, a pontoon balance tank (1.7) and a control unit (1.2). The invention has a pontoon structure on the surface of sea and can operate on 24 hour basis with its own equipment and capacities without receiving direct and continuous logistic (power, electricity, water etc.) support from the land. Moreover, the invention also has installations (power connection box, treated and/or waste water reception/discharge points etc.) that can receive direct and continuous logistic (power, electricity, water etc.) support from the land when required.

The invention comprises at least 4 different tanks. The number of tanks in different sizes of pontoon for different waste water types can be increased up to 8. The invention has markings and lighting equipment in accordance with international marine regulations.

The invention has connection points which allow sea crafts that are official designated as ships to come ashore and moor. The invention has a card reader system that moored ships shall introduce their waste discharge cards. The invention has a vacuum pump that can vacuum in waste water coming from waste water tanks on boards on the surface of sea. The mentioned vacuum pump operates when the ship’s identifier card is placed on/read by the system on the pontoon.

The invention has an automation, probe and sensor system that verifies that the waste water accepted from the mentioned vacuum pump meets the criteria for the concerned waste water facility.

The invention has a flow meter which measures the flow rate and physical volume of waste water. The invention has an automatic protection system that controls if proper waste water is discharged and automatically shuts down the waste water reception system.

The invention has an automatic grid unit which has 3 mm grid space on which accepted waste water is treated in the first place. The invention has a first tank to store waste water coming from the grid unit before sending it to the treatment tank. The invention has a second tank in which waste water is treated. In the second tank, waste water is treated by aerobic microorganisms based on the membrane bioreactor (MBR) principle. The invention has a programmable Logic Controller (PLC), which is also remotely accessible as necessary that controls all equipment including air pumpblower, water pump, pH measurements, temperature measurements, dissolved oxygen measurements, pressure measurements, and turbidity measurements etc., required for the operation of the MBR treatment system.

The invention has also a third tank in which we can accumulate treated water. Treated water can be pumped from the third tank to outside when necessary. The invention has a fourth tank which stores solid residues, defined as “Sludge” in environmental engineering terminology that is generated from the treatment procedure. There is a bag filter dewatering unit at the entrance of the fourth tank on the invention.

The invention has an electric generator (1.4) and a fuel tank for 24 hour operation of the waste water treatment system that is integrated on and inside the pontoon. There is an inclinometer-pump-tank mechanism to keep the pontoon structure at balance. This system has an automatic equalization tank (1.1) that can receive and discharge water from the sea to the tank placed next to the first tank on the pontoon to eliminate imbalance created by the first tank the weight of which can constantly change depending on the volume of waste water. The invention has a remotely accessible camera surveillance system that continuously monitors and records the area on top of and around the pontoon.

Application of Invention to Industry;

The invention is used for disposal of marine debris at source and can easily be manufactured.
