Abstract

A water treatment process and equipment for implementation of the process are provided. The equipment incorporates a high rate clarifier with series operated inclined parallel plate settlers, followed by adsorption clarification with buoyant media.

Claims (10)

1. An apparatus for altering a liquid containing solids, the apparatus comprising:
an inclined parallel plate separator; and an adsorption clarifier, wherein the inclined parallel plate separator and the adsorption clarifier are in a stacked configuration, wherein the adsorption clarifier is situated above the inclined parallel plate separator, and wherein the apparatus is configured such that the liquid containing solids first enters the inclined parallel plate separator, then the liquid, from which a portion of the solids has been removed, enters the adsorption clarifier.
2. An apparatus for filtering a liquid containing solids, the apparatus comprising:
an inclined parallel plate separator; and an adsorption clarifier, wherein the inclined parallel plate separator and the adsorption clarifier are in a side-by-side configuration, and wherein the apparatus is configured such that the liquid containing solids first enters the inclined parallel plate separator, then the liquid, from which a portion of the solids has been removed, enters the adsorption clarifier.
3. The apparatus of claim 2, further comprising:
a contact tank, wherein the contact tank is upstream of an entry into a chamber containing the inclined parallel plate separator.
4. The apparatus of claim 2, further comprising:
a filter situated downstream of the adsorption clarifier.
5. The apparatus of claim 2, further comprising:
a filter situated downstream of the inclined parallel plate separator.
6. The apparatus of claim 2, further comprising:
a porous hollow fiber membrane filter.
7. The apparatus of claim 2, wherein the inclined parallel plate separator further comprises an air diffusion grid.
8. A method for cleaning an apparatus for altering a liquid containing solids, the apparatus comprising an inclined parallel plate separator and an adsorption clarifier, wherein the inclined parallel plate separator and the adsorption clarifier are in a side-by-side configuration, the method comprising the steps of:
introducing a liquid containing solids into the inclined parallel plate separator, whereby a portion of the solids are removed, yielding a separated liquid;
introducing the separated liquid into an adsorption clarifies;

stopping flow of the liquid containing solids into the inclined parallel plate separator;
air scouring the adsorption clarifier;
air scouring the inclined parallel plate separator; and opening a waste gate to flush a waste liquid containing solids from the apparatus.
9. The method of claim 8, further comprising the step of:
flushing a liquid through the adsorption clarifies after air scouring the adsorption clarifies.
10. The method of claim 8, further comprising the step of:
flushing a liquid through the inclined parallel plate separator after air scouring the inclined parallel plate separator.
