High concentrated effluent generated from manufacturing process 95 cmd will be collected and treated in Stripper & MEE. Condensate will be recycled in process/utility.
The treated water 247 CMD will be sent to CETP. ETP treatment scheme-
1. Primary Treatment
The system will be designed to treat 400 cmd of waste water. Wastewater from Different process, which has gone through MEE treatment along with wastewater from cooling tower, boiler blow down and low concentrated process wastewater. etc. will be collected in the Equalization Tank and air stripped. This effluent will be then be pumped to the Flash Mixer where it is dosed with alum for coagulation. Flash Mixer is followed by a flocculator where poly will be dosed for bigger flock formation. This effluent is overflowed into the settling tank where the solids will be settled down and removed.
2. Secondary (Aerobic) Treatment:
The system will be designed to treat 400 cmd waste water. The neutralized effluent will enter the bioreactor. In the bio reactor, dissolved organic material is degraded by the micro–organisms present in the bio reactor. Oxygen required for the oxidation of organic matter will be provided by means of proposed diffuser aeration system which will mix the contents of the bioreactor. The mixed liquor will overflow into Secondary Settling Tank (SST). In the secondary settling tank, solid-liquid separation takes place and solids i.e. biomass will settle at the bottom of the tank. Settled biomass will be recycled to the bio reactor for maintaining the MLVSS concentration by using proposed sludge recycle pumps and excess biomass will be wasted periodically to the sludge sump. Two stage treatments are proposed where the overflow from the 1st stage clarifier will enter the 2nd stage bioreactor where the non-degraded organics from the 1st stage bioreactor will be treated. The clear overflow from the 2nd stage Secondary Settling Tank will be Collection in the intermediate sump. 3. Tertiary Treatment: The system will be designed to treat 400 KLD of waste water. The clear effluent from the intermediate sump will be pumped by tertiary Feed pumps through the pressure sand filter (PSF) & activated carbon filters. The final treated effluent will be Collected in the final Collection tank from where it is discharge to CETP (247 CMD). 4. RO & MEE (Proposed) Balance treated effluent from ETP and low COD effluent from process is send to RO plant (400 CMD). RO permeate is recycled back to utility and reject send to MEE Plant (80 CMD) for treatment. MEE condensate recycled back into utility and Sludge (Salt) disposed to CHWTSDF. 5. Sludge Handling: Primary sludge, excess biomass from the secondary treatment and backwash water from PSF will be collected in the sludge sump. From the sludge sump the sludge will be
pumped to the decanter/valuate for dewatering. The solid cake from the decanter/valuate will be sent for disposal to Hazardous waste disposal site. The filtrate from the decanter/valuate will be drained to the collection tank. Design details and Performance Projection of ETP are tabulated below: Sr. No
Action plan for disposal of Fly ash generated from Boiler Coal will be used as fuel in boiler and generated ash shall be collected and sold out to nearest brick manufacturer and land filling. Details are shown in table as above.

Schematic of EIA Purpose
Figure below indicates schematic representation of the feasibility drawing which gives EIA purpose
Industrial area where the plant is to be located, comes in Taluka Roha of Raigad district in Konkan, near west coast of Maharashtra. Site is well connected by rail and road. Nearest railway station is Roha 4 km NW of site and Kolad-Roha road is 300 m to North from site which meets National Highway-66 (Panvel- Edappalli). Site is at a distance of 100 km from Mumbai. The plant facility is to be located in well-developed notified industrial estate and there is no human habitation in immediate vicinity of the plant.
Land form, Land use and land ownership
Land Form: Land is on plain contour; it is flat terrain.
Land Ownership: Land ownership is with project proponent (Deepak Nitrite Limited). Refer Annexure II.
Topography (along with map)
The Raigad district is divided into three parts on the basis of its topography.
The rock of the district is trap. In the plains it is found in tabular masses a few feet below the soil and sometimes standing out from the surface. In the hills it is tabular and
is also found in irregular masses and shapeless boulders varying from a few inches to several feet in diameter. In many places the surface of the trap has a rusty hue showing the presence of iron. River on North of the plant site is the main line of drainage which on going further meets Sea near village Korlai. This river flows east to west and helps in replenishment of ground water table.
Existing land use pattern
The land (Plot no 8, 32 to 34) are vacant at present and is for industrial use. Deepak Nitrite Limited will start activity on the said plot only after obtaining Environment clearance & Consent to establish from competent authorities. Hence, there was no activity carried out on this plot till now & existing EC/ CTE is not applicable.
Existing infrastructure
The Plot is located in well-developed notified MIDC area. Existing infrastructure is well developed.
Soil classification
There are four chief varieties of soil in Raigad district: ailuvial and alluvia, powdered laterite and trap, clay mould resting on trap, and soil containing marine deposits with, much sand and other matter in concretion.
The soil in the Roha tahsil is sandy loam and clay-slit. Sandy loam is ideal for plants that need more soil drainage than usual. Chronic incurable "overwater" will appreciate the drainage benefits sandy loam soil provides, since good drainage in soil decreases the chance of plant disease. The large soil particles of sand in sandy loam soil increase the soil's capacity to let water flow through, making it easier for fresh water to move through the planting media.
Climate data from secondary sources
Overall climate of this region is equable with high rainfall in monsoon season and very few days of extreme temperatures. The mean annual temperature ranges from 300C to 330C. The maximum temperature of the hottest month in this area varies from 350C –
400C in April-May while minimum temperature of coldest month varies from 15oC to 20oC. Extremes of temperatures, like 46-48oC in summer and 10-120C in winter, may be experienced for a day or two in respective season. The area has humid climate. Relative humidity varies from 25% to 85%. Driest days being in summer and wettest ones experienced in July. The rainy season is mostly confined to southwest monsoon & is
responsible for fresh water supply.
Social infrastructure available
Nearest town is Roha which is about 4 km from site. Social infrastructures such as schools, Hospitals, market place and other amenities are available. Transport facilities by rail and road are available.
• Infrastructure facilities available at established MIDC site.
