WetSep

Overview

The WetSep System is a patented product providing a turn-key solution for influent control. Designed and built in Hong Kong, the WetSep is a versatile system and can be applied in various types of industries.

WetSep has established itself as good maintenance free system and has satisfied the needs of many clients from International companies.

Surface runoff such as grit, small solid waste and sewage from temporary sanitary facilities will produce wastewater. The wastewater usually contains high concentration of suspended solid, BOD, ammonia and E.coli.

In 1998 Waste & Environmental Technologies Ltd. innovated WetSep system, and we have delivered WetSep to 16 different countries including USA, Canada, Singapore and Taiwan.

Characteristic

- Efficient

• 80-88% of suspended solid, oil and grease from the influent are removed in the first stage
• 99.5% of suspended solids are removed after the WetSep treatment with effluent suspended solid level ＜30mg/L in the second stage.

- Low Cost

• Low capital and operating cost
• Low maintenance cost

- Simple

• Treatment Package of oil filtration, suspended solid removal plus reduction in levels of BOD and COD
• No Power driven mechanical parts, all done by natural gravity
• Simple operation designed for unskilled labour
• Designed for easy transportation and installation

Structure of the WetSep

Part A Impinging Stream Reactor (ISR)

Conventional flocculation, coagulation and sedimentation for the treatment of water and wastewater requires a series of mixing and pumping motors that require consumption of energy.

The WetSep system uses the ISR that requires no driven motors which reduces the requirement for energy and simplifies the entire system. The ISR 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 a wide range influent water quality.

The influent water first passes into the ISR for the first stage of treatment. The ISR removes between 80-85% of the suspended solids (SS), oil and grease from the influent water.

Part B Universal Processing Chamber (UPC)

The UPC is the secondary treatment component of the WetSep system.  The UPC is designed to accommodate various secondary treatment requirements.

The UPC is designed to be modular unit that allows different treatment systems to be installed such as: lamella plates, coalescing plates, membrane or rapid sand filtration.  The choice of module depends on the requirements of the treatment which various from project to project.

Effluent from the ISR and UPC treatment processes removes more than 99.5% SS.
