BAMROLI, GUJARAT, INDIA
Serving the Pandesara industrial estate, the 40,000 m3/d wastewater reuse plant at Bamroli, Gujarat, was a trend-setter for municipalindustrial partnerships involving the use of municipal treated sewage effluent (TSE) by industrial end-users. Following the success of the
initial plant, which was commissioned in 2014, an accompanying plant with a capacity of 35,000 m3/d is under construction and scheduled for
commissioning in 2019. The new plant will serve the nearby Sachin industrial estate.
EPC contracts for the first and second plants were awarded to Enviro Control Associates in 2012 and 2017 respectively, both with a 10-year O&M
period. The first plant uses Toray RO membranes, with rapid gravity sand filtration and ultrafiltration pretreatment stages, while the second
uses Hydranautics membranes, with a cloth disc filtration pretreatment stage. Both systems have a recovery rate of 75%, reducing TDS from
1,400 ppm in feedwater to below 500 ppm in their product water.
The plants take secondary treated wastewater from a nearby wastewater treatment plant run by Surat Municipal Corporation, reducing the
industrial use of freshwater resources and increasing supplies of potential drinking water. Surat Municipal Corporation offers the treated
effluent to industrial users at a rate of INR25/m3 ($0.35/m3), compared to INR30/m3 (0.42/m3) charged for freshwater.
