What are the parameters of ETP?

➢ Whatever is the law, the parameters tested at ETP inlet point should be tested at ETP outlet point to assess if the water quality after treatment expected is achieved. pH, color, DO Temperature, COD and BOD (can be tested monthly if not possible weekly) Heavy metals, ammonia, chromium, etc.

What are the parameters of waste water?

Wastewater Parameter Septage, mg/L Relative Strength Ratio (Septage : Sewage)
Total Kjeldahl Nitrogen 600 15 : 1
Ammonia Nitrogen 100 4 : 1
Total Phosphorus 210 25 : 1
Oil and Grease 5,500 55 : 1

What are the parameters of effluent discharge?

parameters of the effluent do not exceed the permissible limits set out in the Second Schedule….

Parameter Unit Maximum permissible limit
Nitrate as N mg/l 10
Total Kjeldahl Nitrogen (TKN) mg/l 25
Nitrite as N mg/l 1
Aluminium mg/l 5

What are the parameters of sewage treatment plant?

This article discusses the treated parameters in the Sewage treatment plant (STP)….

Parameter Required Standards
pH 6.5-8.5
Suspended Solids <10mg/l
Ammonia Nitrogen <5mg/l
Fecal Coliform <100 MPN/100ml

What is COD and BOD in ETP water?

The biochemical oxygen demand (BOD) represents the amount of dissolved oxygen (DO) consumed by biological organisms when they decompose organic matter in water. The chemical oxygen demand (COD) is the amount of oxygen consumed when the water sample is chemically oxidised.

How is ETP capacity calculated?

Capacity of utility water distribution pump = 35.73 USgpm (based on previous calculation)…From water balance above we can see that :

  1. Capacity of utility water package (using filtration & reverse osmosis) = 252.06 USgpm.
  2. Capacity of potable water package = 25.2 USgpm.
  3. Capacity of demineralized water package = 45.57 USgpm.

What are water quality parameters?

Water quality parameters include chemical, physical, and biological properties and can be tested or monitored based on the desired water parameters of concern. Parameters that are frequently sampled or monitored for water quality include temperature, dissolved oxygen, pH, conductivity, ORP, and turbidity.

What is BOD limit in wastewater?

In general, maximum allowable concentration for direct environmental wastewater discharge fall around 10 mg/L BOD and maximum allowable concentrations for discharge to sewer systems around 300 mg/L BOD.

What is BOD and COD parameters?

Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are two of the most important parameters to characterise (measure the degree of pollution) of wastewater. BOD, the biological demand for oxygen a source of water has, is the amount of oxygen used by microorganisms to break down organic substances.

What is COD BOD ratio?

The ratio COD/BOD is defined as the portion of biodegradable organics compared to total (bio + non bio) degradable organics. This ratio is generally greater than 1, but can be equal to 1 if sample has only biodegradable organics.
