Effulent Recycling
WWI has experience in providing quaternary systems to provide an effluent quality suitable for re-use in applications such as irrigation, process waters and washwaters. These system include disinfection processes, for example chlorination and granular activated carbon (GAC) systems, filtration process, typically micro- and ultra-filtration, reverse osmosis and ozonation processes.
A Membrane Bioreactor (MBR) is an advanced treatment process providing a high quality treated effluent with a small footprint. It has the advantage of not requiring primary and secondary clarification stages or tertiary treatment processes and the further benefit of producing less sludge than a conventional secondary treatment processes.
The MBR process is highly suitable for both municipal and industrial applications. The process separates the treated wastewater from the purifying bacteria through membrane filtration rather than in a settling tank. The treated effluent that passes through the membrane is of a quality that is suitable for direct discharge without the need for further treatment or can be re-used, for example, irrigation, district cooling systems, industrial process waters.
WWI Services has been a pioneer in the use of the Kubota MBR technology, for which WWI has the exclusive licence for Kubota Membrane Systems within Pakistan
