Wastewater is used water that must be treated before it is released into another body of water, to prevent further pollution of water sources.
Wastewater is generated from a variety of sources. Everything you flush down the toilet or rinse down the drain is considered wastewater. Rainwater and runoff, along with various pollutants, flow down street gutters and end up at a wastewater treatment facility.
Let’s understand the concept of percent removal efficiency in WWTPs.
How do cities manage wastewater to ensure safe discharge?
There are three levels of wastewater treatment: primary, secondary, and tertiary treatment.
Most municipal wastewater treatment plants use primary and secondary treatment levels, with some also employing tertiary treatment. The type and sequence of treatment may differ from one treatment plant to the next.
How about industry waste? Can public wastewater treatment plants eliminate all toxic chemicals?
Because, the public wastewater treatment systems cannot effectively remove all contaminants, commercial and industrial waste is not sent directly to treatment plants.
Wastewater from commercial and industrial processes is typically classified into four types, and handled accordingly:
1. Some wastewater can be treated on-site and reused for various purposes, within the plant.
2. Some wastewater treatment plants are specifically designed to treat industrial wastewater.
3. Some wastewater is similar to household wastewater and can be treated at a public wastewater treatment plant. Alternatively, the water could be pre-treated and sent to a public wastewater treatment plant.
4. Toxic wastewater from certain processes must be treated on-site or disposed of as hazardous waste.
Status of wastewater treatment
The main causes of high levels of pollution in the Yamuna river are untapped wastewater, from unauthorized colonies and poor quality of treated wastewater discharged from WWTPs.
The 35 sewage treatment plants in 20 locations across Delhi can treat up to 577 MGD of sewage, and have been using approximately 90% (514 MGD) of their capacity. Currently, Delhi produces approximately 744 million gallons of sewage per day.
What is percent removal efficiency in WWTPs?
The removal efficiency of a specific constituent in a treatment plant, or treatment unit is frequently expressed as a percentage (%).
The well-known concept described in Equation gives the removal efficiency:
E= (Input concentration − Output concentration)/ Input concentration
= Removed concentration/Input Concentration
=1 – Output concentration/ Input concentration
= 1 − Remaining fraction
