STP Tanks

Product Description

An STP (Sewage Treatment Plant) tank is a crucial part of a sewage treatment system, used to treat and purify wastewater before it is released back into the environment or reused. The tanks are designed to filter out contaminants like solids, oils, and harmful microorganisms from sewage water. Here's a general overview of how an STP tank works:

Primary Treatment: In this stage, large solids, oils, and grease are separated from the sewage through physical processes like settling and flotation.

Secondary Treatment: The remaining water undergoes biological treatment, where microorganisms break down organic matter in the wastewater.

Tertiary Treatment: This final stage further purifies the water, usually by removing any remaining nutrients, chemicals, or pathogens. It may include processes like filtration, chemical dosing, or disinfection.

There are different types of STP systems (e.g., activated sludge, moving bed biofilm reactors, or MBR) depending on the treatment process and the level of purification needed.

The treated water from the STP tank is typically safe to release into natural water bodies or can even be reused for non-potable purposes like irrigation or industrial cooling, depending on the systems design.
