Electrocoagulation reactor
An electrocoagulation reactor is provided for treating waste water and removing contaminants therefrom. The reactor is typically a six sided rectangular water tight housing which has an inlet pipe and an outlet pipe. There are a multiplicity of charged plates located parallel to one another within the housing. Adjacent plates are typically oppositely charged and water will pass between the plates as it flows through the reactor. The electric field between the plates will help encourage coagulation of waste matter which then may be removed from the waste water downstream of the electrocoagulation reactor.
1. A method for treating water, the method comprising the steps of:
providing a multiplicity of plates;
providing a cartridge adapted to removably receive a multiplicity of plates so as to maintain the plates in parallel alignment;
providing an electrocoagulation reactor, the electrocoagulation reactor having a cell tank adapted to receive the cartridge, the cell tank having an intake pipe, the intake pipe having a first pump engaged therewith and an intake port and a discharge pipe and a discharge port;
loading the cartridge with at least some plates;
placing the loaded cartridge into the cell tank;
transporting a quantity of water from a distant location to the intake port of the electrocoagulation reactor via the intake pipe and the first pump;
subjecting the water in the reactor to an electric field;
moving the water through the electrocoagulation reactor;
removing the cartridge from the electrocoagulation; and
discharging the water from the electrocoagulation reactor to the discharge pipe.
2. The method of claim 1 further including the step of:
defoaming the water discharged from the electrocoagulation reactor.
3. The method of claim 1 further including the step of:
clarifying the water discharged from the electrocoagulation reactor.
4. The method of claim 1 further including the step of:
providing a settling tank and allowing the water discharged from the electrocoagulation reactor to reside in the settling tank so that any particulate matter may settle out from the water.
5. The method of claim 1 further including the steps of providing a sludge thickener downstream of the electrocoagulation reactor and residing the water discharged from the electrocoagulation reactor in the sludge thickener for thickening any sludge contained therein.
6. The method of claim 1 wherein, following discharging the water from the electrocoagulation reactor, the water goes to a second electrocoagulation reactor for subjecting the water to an electric field in the second electrocoagulation reactor.
7. The method of claim 1 , wherein the cell tank has an open top and the placing and removing steps are accomplished through the open top.
8. The method of claim 1 , wherein the electrocoagulation includes a second cell placed in series with the first cell.
9. The method of claim 1 , wherein the cartridge includes a multiplicity of slots each dimensioned to receive a plate.
10. The method of claim 1 , wherein the cell tank includes a sump portion and further including the step of removing waste from the sump portion.
11. The method of claim 1 , further providing handling straps for engaging the cartridge to assist in the loading and removal steps.
12. The method of claim 1 , wherein the step of providing a multiplicity of plates includes providing at least some of the multiplicity of plates having a shorter height than other of the multiplicity of plates and wherein the loading steps includes loading some of the multiplicity of plates having a shorter height.
