Wastewater Treatment Built Around Your Process, Not a Generic Template.

Industrial wastewater does not behave generically — and industrial ETP design cannot be generic either. Pharmaceutical effluent with high COD and TDS requires a different configuration than textile dyeing wastewater with colour and high salt loading, which differs again from food processing effluent with high BOD and fats. The starting point for every GSI industrial ETP engagement is a full characterisation of your specific effluent — its composition, variability, temperature, flow pattern, and regulatory discharge obligation.

Treatment configuration is then engineered unit-by-unit: physical-chemical primary treatment, biological secondary treatment (MBR, MBBR, ASP, UASB, or CFICASS for textiles), and advanced tertiary stages (HRRO, UF, ion exchange) where recovery or reuse is required. For ZLD obligations, evaporation and crystallisation stages are incorporated and sequenced for the specific concentrate characteristics of your effluent.

Our industrial ETP experience spans India's most demanding effluent streams — textile cluster CETPs, pharmaceutical ZLD plants, food and beverage ETPs, tannery ZLD, and CBG plants.
