A sewage treatment plant (STP) processes domestic and municipal wastewater through biological and physical stages before safe discharge. This guide explains every stage — from screening to sludge handling — and why it matters for compliance.

Effluent treatment plants and sewage treatment plants serve very different purposes — and mixing them up can lead to serious compliance failures. Here is a clear breakdown of how ETPs and STPs differ in design, application, and regulation.

RO technology removes dissolved salts, heavy metals, and contaminants that conventional filtration cannot. Learn how reverse osmosis systems work, where they are used, and what makes them the preferred choice for high-purity water applications.
