What are effluent standards?
Effluent standards are concentrations of pollutants expressed in terms of parts per million for waste water discharged through outfall pipes from publicly owned sewage treatment plants or industrial plants.
What are the parameters of effluent discharge?
| Parameter | Unit | Maximum permissible limit |
|---|---|---|
| pH | – | 5 – 9 |
| Chemical Oxygen Demand (COD) | mg/l | 120 |
| Biochemical Oxygen Demand (BOD5) | mg/l | 40 |
| Chloride | mg/l | 1500 |
What is Gpcb limit of COD of the treated effluent water from ETP *?
In India COD value limit up to >250mg/I .
What is effluent standard and stream standard?
2. The Stream standard is the standard of the water in a particular water course to which a sewage treatment plant is discharging into. If a stream standard exists the Effluent standard for a particular WWTP is set by working back from the Stream standard.

Is standards for effluent discharge?
For discharge of an effluent having a BOD more than 30 mg/l, the standards shall conform to those given above for other receiving bodies, namely, sewers, coastal waters and land for irrigation. Bio-assay shall be made compulsory for all the industries, where toxic and nonbiodegradable chemicals are involved.
What are the sources of effluents?

- Domestic.
- Industrial.
- Commercial.
- Agricultural activities.
- Surface runoff or storm water.
- Any sewer inflow or sewer infiltration.

What is treatability study?
What is a treatability study? A wastewater treatability study is a study or test that tells us how the wastewater might be treated. If the study is done correctly, it will clearly identify the problem you’re seeing in your wastewater stream, helping ensure the proper treatment solutions are considered.
What are stream standards?
Stream standards, designed to prevent the deterioration of existing water quality, set limits on the amounts of specific pollutants allowed in streams, rivers, and lakes. The limits depend on a classification of the “maximum beneficial use” of the water.
What is effluent discharge?
Effluent discharge is liquid waste, other than waste from kitchens or toilets, surface water or domestic sewage. It is produced and discharged by any industrial or commercial premises, such as a food processing factory or manufacturing business.
What is effluent monitoring?
Effluent monitoring is the collection and analysis of samples or measurements of liquid and gaseous effluents to determine and quantify contaminants and process-stream characteristics, assess any chemical or radiological exposures to members of the public, and demonstrate compliance with applicable standards.
