WATER TREATMENT AND REUSE SYSTEM

摘要

System and methods are disclosed for filtering wastewater. In one embodiment, a water filtering system comprises a first filtering stage and a second filtering stage. The first filtering stage receives a flow of wastewater, and uses electrocoagulation to separate suspended particles from the wastewater and produce filtered wastewater. The second filtering stage receives the filtered wastewater from the first filtering stage, and uses mechanical filtering to remove suspended particles from the filtered wastewater and produce filtered water that is substantially free from suspended particles.

主权项

1. An apparatus comprising, comprising:
a water filtering system for filtering wastewater that uses electrocoagulation, the water filtering system comprising:
a pre-filtering stage that receives the wastewater, and substantially removes oil from the wastewater before electrocoagulation;a first filtering stage including:
an electrocoagulation system that receives the wastewater from the pre-filtering stage at its bottom, and injects a current through the wastewater as the wastewater flows up through the electrocoagulation system and out its top; andat least one tank that receives the wastewater from the electrocoagulation system through a gravity flow, and temporarily stores the wastewater to allow suspended particles separate from the wastewater and fall to a bottom of the at least one tank; anda second filtering stage that receives the filtered wastewater from the at least one tank, and uses at least one mechanical filter to remove suspended particles from the filtered wastewater.
