In December 20sets STP Loading for Rural Domestic Wastewater Treatment,there're many capcity from 5-30tons.Today let's check it out what the sewage treatment plant and how does it work.
Normally wastewater from sinks, baths, washing machines, toilets and other appliances has to go somewhere.Sewage treatment plants collect, treat, and discharge wastewater, providing a service essential to environmental and public health.
How does it work?
Sewage treatment plants run wastewater through multiple treatment stages. After preliminary filtration, there are three main stages of wastewater treatment (primary, secondary, and tertiary), with the third stage reserved for polishing.
Primary stage
The primary stage involves separating solids from liquids. The sewage is pumped into sedimentation tanks, where gravity forces solids to the bottom of the tank. The water is then released, leaving behind a sludge/slurry.
Secondary treatment is the biological treatment stage that breaks down organic contaminants in wastewater.
Wastewater is considered clean after secondary treatment, but tertiary treatment returns it to an even higher quality for release in protected waters.
