What is discharge in wastewater treatment?
1) Wastewater discharge means the amount of water (in m3) or substance (in kg BOD/d or comparable) added /leached to a water body from a point or a non point source. 2) Sewage effluent (or discharge) means treated sewage discharged from a sewage treatment plant.

What is the permissible limit of COD in wastewater?
According to standards of Central Pollution Control Board, permissible value of BOD is 30 mg/l and COD is 250 mg/l.

How many cubic meters per day of wastewater is allowed to discharge by a Category A establishment?
The effluent standards apply to industrial manufacturing plants and municipal treatment plants discharging more than thirty (30) cubic meters per day. (a) Except as otherwise indicated, all limiting values in Tables 2A and 2B are 90th percentile values.
What is flow rate in wastewater treatment?
The average sewage flow rate is usually about the same as the average water use in the community. In a lateral sewer, short-term peak flow rates can be roughly four times the average flow rate. In a trunk sewer, peak flow rates may be two-and-a-half times the average.
What is permissible limit of BOD?
The limiting value standard acceptable for BOD are 30 mg per liter for inland surface water, 350 for public sewer, 100 for land and 100 for marine coastal areas.
What is good COD level?
Influent COD in normal domestic sewage is therefore generally 600 – 900 mg/l and it is then treated to at least 75 -100 mg/l before discharge to minimise pollution potential.
What is BOD and COD in waste water treatment?
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 do you calculate ETP plant capacity?
Water capacity can be reduced by 50%, so that:Capacity of utility water package = 126.03 USgpm.Capacity of potable water package = 12.6 USgpm.Capacity of demineralized water package = 22.78 USgpm.Capacity of utility water distribution pump = 35.73 USgpm (based on previous calculation)More items...•
What is the largest Wastewater Treatment Plant?
Blue Plains Advanced Wastewater Treatment PlantDC Water's Blue Plains Advanced Wastewater Treatment Plant is the largest plant of its kind in the world. On an average day, the facility treats close to 300 million gallons of wastewater and has the ability to treat over 1 billion gallons a day at peak flow.
How do you measure for a sewage treatment plant?
The sewage treatment plant should be installed for a minimum of five people (5P) Households containing more than three bedrooms must add 1P for every extra bedroom. For example, a household containing five bedrooms would need a 7P sewage treatment plant.
