How it works

Nordic Water is famous for their extremely strong and robust Rotoscreen, which is a step-type screen used at Head of Works. They are also instrumental in the design and installation of perforated Band screens. Due to the hydraulic effect of all the extra steel on the screen, flow capacity is reduced for single directional screens. Nordic Water offer a side or double screen entry (known as cross flow), which ensures higher flow without changing channel civil requirements.

MEVA MPS is a modern perforated plate screen developed for use at waste water treatment plants and process industry with high demands for sturdy design, high separation degree and low costs. A lot of work has been spent on developing the design of the brush and strainers in order to bring the brush wear and flush water consumption to a minimum. MEVA MPS is hygienically fully enclosed and is delivered with a standard perforation of 2-12 mm.

For Mhlathuze Water, Circuit Water have just installed their largest screens to date. In total there are four 12 mm, punched hole, band screens. Two of which are installed at a sea water abstraction pump station (Alkanstrand) and are manufactured with 316L stainless steel. Futhermore it offers cathodic protection against corrosion. These screens are 1,8m wide and 11m high.

Another two punched hole band screens have been installed at the Nsezi WTP pump station for Mhlathuze Water to screen water from the Nsezi dam before it gets pumped to the water treatment plant. These two are manufactured from grade 304 stainless steel and are 13m tall. These are capable of a peak flow of 850m3/min.
