Abstract
A liquid solid separator has a main container wherein a rotating filter belt receives influent for liquid sold mixture sieve processing. A filtered water collections tank, a pressurized water supply are sources of wash water inputs. Cold and hot water pressurized water supplies are also potential supply sources. Load balancing of inputs and single and dual wash water pumps are also described.
Claims6
A rotating filter belt system comprising:
- a tank having a screened water outlet (4);
- an endless, inclined, rotating filter belt disposed in the tank, dividing the tank into an upstream unfiltered volume and a downstream screened water volume;
- a wash system for directing water at the rotating filter belt to wash the rotating filter belt;
- a screened water drain line (107) in fluid communication with the screened water outlet (4) for receiving screened water;
- a screened water tank (100) in fluid communication with the screened water drain line (107) for collecting screened water;
- a recirculation line fluidically connected to an outlet of the screened water tank (100) and in fluid communication with the wash system for supplying water to the wash system;
- a booster pump disposed in the recirculation line;
- a source of pressurized water is fluidically connected to the recirculation line;
- a temperature sensor attached to a conduit;
- and
- a control system for selectively supplying water to the wash system from either the screened water tank (100) or the source of pressurized water, based on the quantity of water present in the screened water tank (100).
