DRYCAKE engineers, packages, delivers, installs, commissions and supports Inlet Works Screening and Grit Removal systems, Decanter and Disc-Stack centrifugal mechanical separation packages, solid waste systems thermal drying and evaporation technology, and conveyor systems.
The DCO combined treatment systems integrates screening and grit separation with the option of fat, oil & grease (FOG) removal, all within a single package unit. Wastewater enters the screen section where gross solids are removed from the flow, washed, compacted and dewatered. Depending upon the solids’ properties, a volume reduction of around 40% dry solids can be achieved. The screened effluent then discharges to a hopper section where grit and sand settlement is induced. The grit is conveyed to a grit classifier and can be further washed prior to dewatering and disposal into a container.
The DCO includes two variants, DCO 2 and DCO 3. DCO 2 integrates two treatment sections, 1) screening and 2) grit/sand separation.
The DCO 3 incorporates the DCO 2 sections plus a further treatment section for FOG removal.Both variants may be fitted with air diffusers to impart improved separation of attached organic matter from the grit and sand particles. With the DCO 3, this will also enhance flotation and removal of FOG which can then be drawn off and disposed of into a separate container.
With air-agitation and screw classifier washing, grit and sand separation > 95 % removal of 0.20 – 0.25 mm (200 μm – 250 μm) grit particles in addition to organic matter removal > 97 % is attainable.
DCO systems are supplied for direct installation into prepared level ground. The screen section can be supplied with or without the option of a bypass rake screen. Continuous bagging systems are available to receive screenings and grit. This will abate odours and the screenings can be sealed without any personal contact.
