Abstract

A system and apparatus configured to facilitate on-site treatment of wastewater from a residence is described. The system is configured to immediately treat wastewater as it is generated, on an as-needed basis, and works to remove undissolved down solids and reduce dissolved materials concentrations to a uniform level prior to transmission of the wastewater to municipal waste water treatment facilities and/or any non-drinking application. The system employs a two-stage treatment apparatus where the first stage is configured to pre-grind and decompose undissolved solids of the wastewater and the second to reduce dissolved materials concentrations. The first stage uses turbidity meters, and the second stage uses pH, BOD and conductivity to ensure a uniform output from each stage. A fast decomposer has rotating filters which operational modes ensure that the filters do not become clogged with solids in a ‘cake’ form simultaneously.

Dependent claims

A system for the on-site pre-treatment of wastewater, including solids, from a sewage line without a heated filter comprising:

at least one grinder;
at least one decomposer;
at least one control valve, said control valve disposed in communication with said at least one decomposer;
pipelines;
a circulation pump, said circulation pump configured to circulate wastewater through said pipelines, to and from said decomposers;
filter mesh, said filter mesh disposed within said first decomposer;
wherein said filter mesh is configured to collect undissolved solids, forming a filter cake on said filter mesh during a filtration mode;
heat sources, said heat sources disposed within said at least one decomposer, isolate from the filter mesh;
wherein said at least one decomposer decomposes the undissolved solids within the watewater during a decomposition mode;
wherein said at least one decomposer is configured to decompose said filter cake during said decomposition mode;
and
wherein said filter mesh is disposed within a glass tube of said at least one decomposer.
