Solids Separator

A solids separator is used to separate easily settleable solids (e.g. sand or slag) from effluent or process water. Our solids separators are designed specifically for each application. Therefore particle size and discharging rate of the conveyor screw can be adapted individually to customer requirements.

Function

Functional principle of a solids separator

The effluent is fed into the container from the top. Solid particles settle down at the bottom of the sludge funnel and are carried out by a conveyor screw. Pre-dewatering in the final section of the conveyor trough allows a partly dewatered discharge of solids.
The solids separator can additionally be fitted with lamellas. Its function is then comparable to a lamella separator, whereas relatively large (heavy) particles are discarded only. Residual fine particles can be separated using, for example, a lamella separator.

Fields of Application

When compared to conventional separation units used in the treatment industry, as for example bucket wheels, sizing screens, hydrocyclones, etc., the solids separator is advantageous in situations with a high water flow and relatively small loads of solid particles. Therefore, a solids separator is an affordable alternative not only in terms of acquisition but also maintenance costs. Solids separators are typically used to clarify wash and process water containing sand, grit, slag or glass splinters. The combination of a solids separator and a lamella separator is common practice. Whereas the rotary drum is used to remove large particles, the lamella separator separates residual turbidity material. The pretreatment has the advantage of a much smoother operation of the sludge dewatering process (after the lamella separator).
