Receiving water

แปลว่า(Environmental Engineering) A water which receives wastewater (treated or otherwise) discharges.

Shock load

แปลว่า(Environmental Engineering) Influent wastewater entering the plant which has an unusually high organic content and/or high flow rate.

Denitrification

แปลว่า(Environmental Engineering) The anoxic biological conversion of nitrate to nitrogen gas. It occurs naturally in surface waters low in oxygen, and it can be engineered in wastewater treatment systems.

Secondary treatment

แปลว่า(Environmental Engineering) In wastewater treatment, the conversion of the suspended, colloidal and dissolved organics remaining after primary treatment into a microbial mass with is then removed in a second sedimentation process. Secondary treatment included both the biological process and the associated sedimentation process.

Suspended growth reactor

แปลว่า(Environmental Engineering) A reactor in which the microorganisms are suspended in the wastewater. Examples of suspended growth reactors are activated sludge reactors and anaerobic digesters. See attached growth reactor.
