wastewater treatment


We are able to separate suspended solids from liquid carriers by means of fine aperture screens constructed with wedge wire or perforated hole plates. Standard apertures range from 0.25mm to 12mm, with larger apertures for special applications. Typical applications of these wastewater treatment solutions include removal of rejects, recovery of usable product from waste water, removal of solids as the first step in waste water treatment,  raw water intake screening, product thickening, thickening of waste water solids before dewatering.


Screened solids, floated solids, (eg, DAF)or settled solids (eg. clarifier underflow) can vary between 3% to 10% DS. These solids can be further dewatered by means of a pressing principle to produce 20-50% DS. The resultant volume reduction offers huge savings on transport cost. For eg. dewatering from 5% to 50% DS results in 10 times reduction in volume. Payback on capital investment can be rapid depending on the type of solids and volumetric reduction achieved.


Certain solids (like minerals and sand) have a relatively fast settling time, so these can be removed by means of our grit classifiers usually installed after the screening stage. Additional washing to remove organic material is offered by means of air, water jet or vortex agitation to achieve between 50 to 95% organic reduction.
