Sludge Treatment

WABAG uses best-in-industry technical know-how and expertise to treat industrial effluents such as oily waste and organic matter to form sludge, which is a rich reservoir of bio-gas. We use specialised processes for the extraction of valuable biogas which, in turn, serves as the energy fodder for the entire wastewater treatment plant and fuelling energy-intensive, process cycles in the parent industry. As a result, the carbon footprint as well as dependence on outside power sources is reduced.

WABAG technologies also ensure that the digested sludge does not pose a threat to the environment. Further, our technologies like BIOZONE-AD®, which use ozone with pre-digested sludge for an accelerated and more comprehensive oxidative decomposition of the incoming sludge enable an ultra-efficient sludge digestion.

Our sludge treatment solutions can be customised for any business model, be it EPC, DBO, BOT or BOOT. Our sludge management system at Reliance PTA Recycling Plant in Dahej is a model plant where Biogas generated from the sludge is used for heating (resulting in 40% savings in OPEX). As a result of the sludge drying process, nutrient recovery is also ensured.
