Types
This type of treatment aims to remove contaminants from the sewage
What is sewage treatment?
This method is based on mechanical, thermal, and other physical processes
What is physical method based on?
This treatment removes material that will either float or readily settle out by gravity
What is primary treatment?
It reaches water from a single pipeline or channel
What point-source pollution is?
This type of treatment mostly have their own specialised facilities
What does industrial treatment have?
Processes based on this method can be used as either primary or secondary treatment steps
Where can chemical method be used?
This treatment also removes more of the suspended solids
What is secondary treatment?
They are broad, unconfined areas from which pollutants enter a body of water
What is dispersed source of pollution?
This type usually treats some kind of waste by containment in anaerobic lagoons before disposal
How agricultural treatment treats animal slurries?
Thanks to this method, the degradation or separation of contaminating components is carried out
What does physico‑chemical method do?
Settled sewage, mixed with fresh sludge that is recirculated from the secondary clarifier, is introduced into the aeration tank
What does activated sludge do?
It includes pathogenic organisms, oxygen-demanding wastes, plant nutrients, synthetic organic chemicals, etc
What is general types of water pollutants?
This type includes treatments such as: ultrafiltration, active carbon filters, electrocoagulation and reverse osmos
What treatment options does leachate treatment have?
Colloidal particles and high‑molecular compounds are gradually adsorbed onto the flocs of activated sludge
How biological method begins?
Removal of additional suspended solids and BOD from secondary effluent
Where is the effluent polishing affective?
The result of contaminated water from one country spilling into the waters of another
What transboundary pollution is?
