Abstract
The present disclosure provides improved methods for conducting a wash cycle in a filtration unit. The methods may be used alone or in combination with one another to achieve the improvements described herein. Filtration units adapted for carrying out the novel methods are also provided. Through the use of the methods and filtration units described, significant economic benefits are obtained without a significant increase in the costs of the filtration unit or in the costs of operation of the filtration unit.
Claims56
A method for carrying out a wash cycle in a filtration device comprising a filter bed of porous filtration media units, an upper plate, a first influent pipe, a first effluent pipe and a scouring fluid inlet pipe comprising a plurality of openings on a top portion of the scouring fluid inlet pipe and a scouring fluid nozzle in communication with at least one of the openings on the scouring fluid inlet pipe, the method comprising the steps of:
- a. directing a scouring fluid from the scouring fluid nozzle into the filter bed, wherein the scouring fluid nozzles comprise a restriction point to provide a jet force to the scouring fluid;
- b. directing a particle removal fluid from the first influent pipe;
- and
- c. removing the particle removal fluid from the filtration unit through the first effluent pipe, wherein the first effluent pipe is located below the upper plate or located above the upper plate such that the distance from a bottom portion of the upper plate to a bottom invert on the first effluent pipe is 15 inches or less.
