Effluent Treatment Plant For Sugar Mill Industry

NOTE:-
As the BOD load is equally distributed in daily discharge, no separate BOD removal is suggested.

As a remedy, our prime and ultra-sophisticated effluent treatment plant for sugar industry is the promising way for get rid of such effluent and wastewater in a controlled way. Besides, our industry clients also find such effluent treatment plants to be pretty economical which consume minimal power and are absolutely designed to comply with the guidelines and prevailing by-laws as are established by the government. Conversely, if left untreated, such effluent can cause a range of grave health hazards and can be a potential threat to environment too. Effluent Treatment Plant For sugar mill.

During this process, an initial homogenization initiative is undertaken which is aligned with the process of ensuring pH neutralization, as is present in effluent, after which solids are broken down which are bigger in size. Then comes the step to target and destroy organic matter as may be present thereby, by the virtue of oxidation where effluent is brought in contact with ozone. Here, organic matter is dissolved into liquid is compressed by use of biogas and this step is followed by effluent getting filtered through a sand filter and then ultra-filtration membranes are pressed into service. In final lap, RO (reverse osmosis) completes this process, which provides a consistent supply of water clean water which can be reused during paper manufacturing process and then vacuum evaporation process is also being relied upon to treat rejection flow. Thus, the water as is drawn out from evaporation process, is also termed fit for reuse, while the solid presence is treated as a waste and is disposed off thereby.

It is important to notice here that such a task and framework, when is put into practice, becomes cumbersome since the level of contamination of effluent becomes higher and it calls for a professional approach by which minimal contamination is left when paper is produced after reusing of such water.

The effluent reach to ETP from all the streams is made homogeneous in the underground equalization tank, after subjected to, bar screen chamber, and Oil and grease trap.

• Air agitation is being provided in the equalization tank to ensure homogeneity.
• Effluent is lifted and transferred to flash mixer, where coagulant/chemicals are being added by dosing.
• Dosing is achieved by automatic dosing pumps for precise quantities of chemical dosing.
• Air agitation is provided in dosing tanks and flash mixer for mixing of solutions.
• The air quantity can be regulated by valves provided in the piping.
• The overflow solution of flash mixer shall be taken to clari-flocculator tank.
• Flocculent chemical is added in this tank with dosing pump, which help the impurities to form large flocs in the form of sludge.
• The clarifier is inclined tube type settler, having tubepac media for sludge separation. These are inclined tubes made out of PVC material, placed at an angle of 600.
• Sludge settles at the bottom of tube settler and treated water goes to biological treatment.
• Sludge from the bottom of the clarifier in being taken to sludge drying beds or filter press system for dewatering.
• Sludge cakes are being formed after separation of water.
• Solid waste will be transferred to land fill or PCB designated sites.
• Sludge settles at the bottom of secondary tube settler and treated water overflows to treated water holding tank.
• Filtered water from sludge dewatering system will be taken back to equalization tank.
• Water from TWHT is being transferred to DMF (Dual Media Filter) for final treatment of TSS.
• Water from DMF is being transferred to ACF (Activated Carbon Filter) for treatment of Color, Odor etc.
• Finally water will be discharged or used for horticulture.
