Zero discharge system by Ion Exchange for Gujarat Ambuja

Ion Exchange has supplied a state-of-art zero discharge plant for Gujarat Ambuja’s (GACL) 4 MT capacity cement plant at Dist. Ropar, Punjab. GACL, part of the HOLICIM Group, has a 30 MW power plant which includes two turbines, each of 15 MW capacity, high and medium pressure boilers 80/45 T/h capacity with operating boiler pressure of 67 kg/sq.cm. each.

The total effluent generated from the utility department of the power plant, is approximately 500 m3/day. This includes blow down from cooling towers, reject/effluent from softeners, demineralisation plant and pressure sand filters. A sharp decline in the water levels of the region and an overall environmental consciousness led the company to set up the first plant of its type in their group, enabling them to achieve their vision for water conservation and zero discharge.

To treat the effluents, Ion Exchange recommended & implemented a scheme that includes extensive pretreatment of water, ultra filtration followed by two-stage reverse osmosis and finally evaporation to handle the reject from the membrane systems. The plant, thus, recovers 85% of the waste water for reuse and achieves zero discharge. At the same time it helps conserve water by reducing fresh water intake through this recycling program.
