Abstract

System for adjusting the quality of wastewater from washing process for reuse It starts with the water from the washing up with a coarse filter. Treated effluent The coarse filter will add stabilizing chemicals such as acids, bases, oxidizing agents, reducing agents, modifiers to neutralize surfactants. And flocculant chemicals are alum, ferric chloride, poly aluminum chloride, polymers, chemical effluent chemicals. Stable and the chemical precipitates are mixed together by a chemical mixing tube. And sent into the adjusting tank Stable and settling Inside the stabilizing and settling tank With a dip membrane filter. Using ultrafiltration type or microfiltration membrane type (Immersed Ultrafiltration / Microfiltration Membrane) for effluent treatment and an aerator. This will help the filling The filter is clogged more slowly. The effluent inside the tank stabilizes and settles. The quantity value is controlled. Of organic and mineral suspensions including microorganisms (mixed-liquor suspended solid) to the range of 3,500 - 8,000 milligrams per liter And when the effluent is valuable Amount of the organic suspension And minerals including microorganisms (Mixed- liquor suspended solid) more than 8,000 milligrams per liter. Must drain the water open Valve on the cylinder block The sediment is then filtered out with a cloth filter press (Filter Press), the water that has been filtered with a submersible membrane filter using ultrafiltration or microfiltration types. (Immersed Ultrafiltration / Microfiltration Membrane) will be sent for disposal. The remaining chlorine in the water is filtered through an activated carbon filter tank. Then continue to filter With a reverse osmosis filter, the water coming out of the reverse osmosis filter has two parts: concentrate water and permeate. ) The concentrate is used for rinsing back in the Clean the filter of the Immersed Ultrafiltration / Microfiltration Membrane and Permeate to be used for washing. Is a cost-effective use of water resources And help preserve the environment It also keeps the water used in the laundry to be of good quality and consistency.

Claims (1)

1. The quality adjustment system of wastewater from washing process for reuse. It consists of a coarse filter (1) for separating dust, lint, and other dirt. The large contaminated wastewater was removed. The water pump (2) will then pump water into the water quality adjustment system from the washing process for reuse. There is a special feature The coarse-filtered effluent is added with stabilizing chemicals such as acids, bases, oxidizing agents, reducing agents, modifiers to neutralize surfactants. And chemical precipitates include alum, ferric chloride, poly aluminum chloride, polymers into the water pipeline with a metering and adjustable chemical pump (3) wastewater. Chemical stabilizers and Chemical precipitation It was mixed with a chemical mixing tube (4) and sent to stabilization and sedimentation tank (5) inside the stabilization and sedimentation tank (5). Immersed Ultrafiltration / Microfiltration Membrane (6) is used for effluent treatment and an aerator (7). The filter is clogged more slowly. Ultrafiltration type immersion membrane filter or type Microfiltration (Immersed Ultrafiltration / Microfiltration Membrane) (6) Water can be filtered using pump suction (8) effluent inside the tank, stabilization and sedimentation (5). The amount of suspended solids is controlled. Those that are organic and mineral substances including microorganisms (mixed-liquor suspended solid) in the range of 3,500 - 8,000 milligrams per liter. And when the effluent has the value of the organic suspension And minerals, including microorganisms (Mixed-liquor suspended solid) more than 8,000 milligrams per liter, the water must be drained by opening the valve on the tank block (9) and then filtering the sediment with a filter press cloth (Filter Press ) (10) The dry, filtered sludge will be sent to the treatment system or discarded further.The water has been filtered with a submersible membrane filter using ultrafiltration. Or Micro Filtration Membrane (Immersed Ultrafiltration / Microfiltration Membrane) (6) will be sucked with a water pump (8) sent to keep in a clear water tank (11), then the water pump (12) will send water. To get rid of the chlorine at The remaining water is filtered through an activated carbon filter tank (13) and stored in the water reservoir (14) .The water in the water reservoir (14) is further filtered with a reverse filter. Reverse Osmosis (15) The water coming out of the reverse osmosis filter (15) has two parts: concentrate and permeate. The concentrated water will be sent to the storage tank (16) for use in backwashing. Clean the Immersed Ultrafiltration / Microfiltration Membrane (6) using a water pump (17) and drain. Discard from the tank (16) when the water is large, the bile (Permeate) is sent to the storage tank (18) to be used back for washing. And water will be added to the tank (18) when the water in the tank is low.
