This Waste Water Treatment Plant for treatment of effluents and Sewage generated by industrial units and housing colony's in ROHA MIDC industrial area was conceived as a joint effort between Maharashtra Industrial Development Corporation and Roha Industries Association and Maharashtra Pollution Control Board.

RIA WWTP Coop. Soc. Ltd. selected Hydroair Tectonics (PCD) Ltd. for implementation of this project. The project was completed through active cooperation from officials of MPCB & MIDC.

1. Application of biomethanation process, with generation of power to cater to power requirements of WWTP, resulting in low power and lad requirement.
2. Application of CAACO technology.
3. Utilization of Ozonation & UV for tertiary treatment, ensuring low chemical consumption.
4. Automatic belt filter press for sludge dewatering.
5. Dry chemical store with chemical dosing arrangement.
6. MCC Room.
7. Fully equipped Laboratory & control room.
8. Administration block with separate conference facility.

PRIMARY TREATMENT	: Equalisation
 			  Neutralisation.
 			  Flash mixing for chemical dosing (Alum)
			  Clariflocculation

SECONDARY TREATMENT	: Anaerobic based on UASB (Upflow Anaerobic 
			  Sludge Blanket)
			  process, with methane gas and power generation.
			  Chemo Autotropic Activated Carbon Oxidation 
			  to replace conventional
			  Aerobic Treatment resulting in power saving & 
			  reduction in sludge
			  production (nil).

TERTIARY TREATMENT 	: Ozonation with Ultraviolet System.
			  Activated carbon filter.

SLUDGE HANDLING 		: Automatic Belt Filter Press. Dewatered sludge 
			  will be stored temporarily and transported to 
			  Government approved designated site .

LOCATION		: Opp. Petrol Pump, MIDC Area,
			  Dhatav, Roha, Dist.  
			  Raigad, 
			  Maharashtra.
TREATMENT CAPACITY	: 25,000 m3/day

LAND : 77,000 m2

POWER GENERATION : 1300 KVA
FROM ANAEROBIC PROCESS

DISPOSAL : Into saline zone by MIDC

1. Capacity		: 25 MLD Capacity

2. Bio - Methnation by Upflow : Most economical method of treatment
Anaerobic Sludge Blanket
Process (UASB)

3. CAACO, Ozonation : For colour removal & tertiary Treatment.

4. Power Generation Potential : 1300 KVA

5. Chemical Consumption : Very less due to CAACO
