INTRODUCING WETSEP
About WetSep
The WetSep System is a patented product providing a turn-key solution for wastewater treatment. The WetSep is a versatile system and can be applied in various types of industries and applications. WetSep has established itself as good maintenance system and has satisfied the requirements of many clients around the world. Surface runoff such as grit, suspended particles and sewage from temporary sanitary facilities will produce wastewater. The wastewater usually contains high concentration of suspended solids, BOD, ammonia and E. coli. In 1998, Waste & Environmental Technologies Ltd. (WET) innovated the WetSep System. We have delivered WetSep to 20 different countries including USA, UK, Europe, Australia, Singapore and Saudi Arabia.
WetSep Journey
WET started its journey in 1998 based in Hong Kong with a vision to develop sustainable solutions for the environment. In 2020, WetSep System was developed which focused on revolutionizing water treatment through innovative technologies. It uses a novel Chemically Enhanced Primary Treatment (CEPT) process that separates liquid and solid wastes from used water in a single step, bringing unprecedented efficiency to water treatment. After successful pilot trials, WetSep delivered to over 20 different countries. The positive results demonstrated significant improvements and laid the foundation for overseas expansion. Continuous innovation remains core to WetSep's growth as it addresses the global need for sustainable water management.
Process Description
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.
The WetSep System uses the concept of CEPT. The first stage of treatment is the Impinging Stream Reactor (ISR) which does not require any driven motors. Thus, it reduces the energy requirement and simplifies the entire system. It combines the process of coagulation, flocculation and sedimentation in one system. By precise engineering of the flow path, flow rate, pressure differential and empirical data, the treatment can be completed in one single vessel. Using Computational Fluid Dynamics (CFD) modelling, the performance of the WetSep System has been optimized to meet the needs of a wide range of influent water characteristics.
The influent water first flows into the ISR for the first stage of treatment. The ISR removes 80-85% of suspended solids (SS) and oil and grease. the second stage of treatment is the Universal Processing Chamber (UPC). It is designed to be a modular unit that allows different treatment systems to be installed, such as lamella plates, coalescing plates, membrane or rapid sand filter, to treat various types of wastewater. The choice of module depends on the requirements of the treatment which varies from project to project.
Effluent from the ISR and UPC treatment processes achieved the removal efficiency of more than 95%.
