INTRODUCING WETSEP

The WetSep System is a patented, turn-key wastewater treatment solution designed to be versatile for a wide range of industries and applications. It is recognized as a strong maintenance-friendly system and has met client requirements across the world. WetSep is typically used to treat surface runoff containing grit and suspended particles, as well as sewage from temporary sanitary facilities.

The wastewater treated by WetSep often has high concentrations of suspended solids, BOD, ammonia, and E. coli. The system was innovated in 1998 by Waste & Environmental Technologies Ltd. (WET), and WetSep has been delivered to clients in 20 different countries, including the USA, UK, Europe, Australia, Singapore, and Saudi Arabia. 

WET began its journey in 1998 in Hong Kong with a vision to create sustainable environmental solutions. In 2020, the WetSep System was developed with the goal of transforming water treatment through innovative technology. WetSep uses a novel Chemically Enhanced Primary Treatment (CEPT) process to separate liquid and solid waste from used water in a single step, achieving high treatment efficiency.

Following successful pilot trials, WetSep was deployed in over 20 countries, and the results showed strong performance improvements that supported further international expansion. Continuous innovation remains central to WetSep’s growth as it responds to the global demand for sustainable water management.

Chemically Enhanced Primary Treatment (CEPT) is recommended by World Bank as the most effective and energy efficient method of water and wastewater treatment due to the high treatment efficiency.

WetSep System (CEPT-based): High treatment efficiency with reduced energy use.

Stage 1 – ISR (Impinging Stream Reactor):

• Combines coagulation + flocculation + sedimentation in one vessel.
• No driven motors → lower energy and simplified design.
• Optimized via CFD modelling for varied influent qualities.
• Removes 80–85% of suspended solids (SS) and oil & grease.

Stage 2 – UPC (Universal Processing Chamber):

• Modular unit allowing options like lamella plates, coalescing plates, membranes, or rapid sand filters.
• Module choice depends on project requirements.

Overall Efficiency: Combined ISR + UPC achieves >95% removal efficiency.
