Overview
Wastewater/STP Analysis is the systematic testing of sewage and treated effluent generated from Sewage Treatment Plants (STPs) to evaluate treatment efficiency and verify the quality of treated wastewater before discharge, reuse or further treatment. The analysis helps assess plant performance, identify treatment deficiencies and demonstrate compliance with applicable CPCB/SPCB standards and consent conditions.
Key Capabilities
- Physical parameters: Colour, odour, temperature, pH, TSS, TDS and turbidity
- Organic pollution parameters: BOD, COD and TOC
- Nutrients: Total Nitrogen, Ammonical Nitrogen, Nitrate and Phosphate
- Microbiological parameters: Total Coliform, Faecal Coliform / E. coli
- Other chemical parameters: Chloride, sulphate, alkalinity, hardness, oil & grease
- Heavy metals: Iron, manganese, lead, chromium, cadmium, nickel, mercury and other applicable metals
- Treatment-performance assessment: Comparison of inlet vs. outlet parameters and removal efficiency
- Reuse-quality assessment: Testing for treated water intended for gardening, flushing, cooling or other non-potable applications
Applicable Regulatory Framework
- Environment (Protection) Act & Rules, 1986 – Environmental compliance.
- CPCB Standards/Guidelines – Sewage and treated wastewater.
- SPCB/GPCB Requirements – Consent and discharge conditions.
- Environmental Clearance (EC) – Project-specific conditions, where applicable.
- Treated Wastewater Reuse Standards – Based on intended application.
