3.0 TREATMENT OF WASTEWATER

The above wastewater streams are segregated into the following three streams foradopting separate treatment schemes

Process WastewaterSugar Plant - 1500 m3/dayDistillery Plant - Spent wash – 960 m3/day

Spent lees – 288 m3/day

Non Process wastewaterSugar Plant - Cooling water blowdown - 567 m3/day

Boiler blowdown - 302 m3/dayDM plant - 76 m3/day

Domestic Sewage - 16m3/day

3.1 TREATMENT OF PROCESS WASTEWATER – SUGAR PLANT & COGEN - 1500m3/day [ Combined capacity of Old ETP & new ETP]

The process wastewater from the proposed expansion will be treated in a full-fledgedeffluent treatment plant provided with the following units

Screen cum Grit Removal Oil and Grease Removal Neutralisation tank Lime preparing tank Monthly wash tank Two stage activated sludge processwed by Secondary Clarifiers Sludge Pit Sludge drying beds Dilution with other waste water streams in Polishing Pond

The treated process wastewater will be diluted with the treated non-process wastewaterin polishing pond. The outlet of the polishing pond conforming to the GSR 422 (E)onland discharge standards is utilized for greenbelt development and sugarcanecultivation.

3.2 TREATMENT OF PROCESS WASTEWATER – DISTILLERY PLANT

The following are the two major wastewater streams generated from the manufacturingprocess of distillation plant.

Spent lees will be subjected to RO& reused back in the unit fordilution of molasses. Reject fromRO will be diluted with otherwastewater streams in polishingpond

Permeate – 216m3/day(recycled to process)RO Reject – 72 m3/day

The Spent wash treatment of the Distillery plant is designed to achieve zero discharge.The treatment of spent wash will result in generation of slops and condensate.Condensate is recycled back to the process for use as fresh water and the slops will beincinerated in the boiler.

Capacity with detention time of spent wash holding tank:

SSL will provide a five (05) days spentwash storage tanks with a holding capacity of4800 m3. No spent wash storage lagoon is proposed.

All the above wastewater streams except for domestic sewage will be routed to polishingpond for dilution with each other. The final quality of the wastewater at the outlet of thepolishing pond will meet GSR 422 (E) onland discharge standards and the same will bemixed with treated wastewater of sugar plant for use in ferti irrigation.

The domestic sewage generated will be subjected to treatment in full-fledged SewageTreatment plant and the treated wastewater will be used for greenbelt development.

Details of Water consumption, waste water generation and wastewater treatment forvarious streams generated from sugar plant, distillery plant and cogeneration plants areshown in Fig – 1.TREATED WASTEWATER DISPOSAL

As detailed above the wastewater generation from the plant varies based on theoperation of process units. The quantity of treated wastewater from the plant for disposalis given below:

The treated wastewater conforming to GSR 422 (E) on land discharge standards will beutilized for ferti irrigation for 270 days and greenbelt development for the balance days.

AVAILABILITY OF LAND FOR FERTI-IRRIGATION

The total wastewater available for use in ferti irrigation is about 2613 m3/day for 270days. The irrigation plan of SSL is designed keeping in view of maximum wastewateravailability during cane crushing season.

Treated wastewater generated from the plant in 270 days 2613 * 270 = 705510m3

Irrigation plan is designed taking into consideration cultivation of sugar cane which is anative crop of the area. The water requirement of sugar cane crops is given below:

The area requirement based on the above water consumption is as follows:

Treated wastewater generated from the plant in 270 days 2613*270 = 705510 m3

From the above table, it can be seen that the maximum area required for irrigation isabout 128.27 Ha. The greenbelt/ferti irrigation area of 32.39 Ha. SSL has entered intoagreements with the surrounding farmers for utilization of the treated effluent over anarea of 150 Ha which is sufficient to utilize the treated wastewater.
