ETP vs STP vs CETP

An ETP treats industrial effluent, an STP treats sewage, and a CETP treats combined effluent from multiple industrial units. The right choice depends on effluent source, contaminant load, reuse goals and regulatory discharge limits.

Quick comparison

Choose an ETP for process wastewater, an STP for domestic sewage, and a CETP for industrial estates that need centralized treatment infrastructure.
