Designed and built in Hong Kong, the WetSep water and wastewater filtration system is a versatile, patented product that provides a highly efficient, simple and economical turn-key solution for influent control.
While primarily created for site-specific treatment of runoff and waste water from construction work, the Wetsep system can be utilised across many industrial applications wherever a compact, flexible and portable water treatment system is required.
The Wetsep water filtration system has been designed to treat continuous flows of contaminated water, is ideal for treating acid sulphate ground water and includes a dual channel pH controller, alarms and data logging capabilities to ensure superior effluent water quality.
Glen Creswick, National Technical Manager - Pumps and Traffic, is excited about the arrival of the first Wetsep unit, which will go to the East Business Unit for trialling. "We have other filtration systems in our fleet, but Wetsep is the next step up in filtration design and will offer our clients further benefits," Glen said. "The Wetsep system is highly efficient, removing 80 to 88 per cent of suspended solids, oil and grease from influent in the first stage and 99.5 per cent of suspended solids in the second stage.
"It’s also an extremely simple process which is driven by gravity, with no power-reliant parts, so it saves on energy and offers extreme ease of operation and maintenance.
"In fact, with no moving parts in the actual treatment system, little maintenance and monitoring of internals are required and breakdowns don’t occur.
"The Wetsep system’s design also makes it easily transportable, with simple connection of all parts for convenient installation or dismantlement and a compact size which requires only a small space for installation," Glen concluded.
So just how does the Wetsep system offer superior performance compared to complicated and lengthy conventional waste water treatment processes which often raise concerns about effluent quality, efficiency and costly energy consumption?
"Wetsep utilises two essential components to create an integrated solution that compacts the physical and chemical processes into one single unit which offers equivalent or better effluent quality," Glen said.
The first component is Wetsep’s patented Impinging Stream Reactor (ISR). Conventional flocculation, coagulation and sedimentation for the treatment of water and wastewater require a series of mixing and pumping motors that consume considerable amounts of energy.
Wetsep’s ISR has no driven motors, reducing the requirement for energy and simplifying the entire system. By combining the process of coagulation, flocculation and sedimentation in one system and precisely engineering the flow path, flow rate, pressure differential and empirical data, Wetsep’s ISR completes treatment in one single vessel.
The secondary treatment component is Wetsep’s Universal Processing Chamber (UPC), a modular unit designed to accommodate the installation of various secondary treatment systems including lamella plates, coalescing plates and membrane or rapid sand filtration, depending on the specific treatment requirements of a project.
"The Wetsep filtration system delivers exceptional performance and we are looking forward to offering this efficiency, along with associated products and service, to Coates clients around the country," Glen said.
