Automated waste water recycling system using advanced electro-coagulation unit

An automated waste water treatment system comprising:

• a collection tank constructed to hold waste water;
• a first flow line connected to the collection tank to output the waste water from the collection tank;
• an electrocoagulation unit connected to the first flow line to receive the waste water and to output the waste water as coagulated waste water into a second flow line;
• a polymer dosage tank to provide a polymer dosage into the second flow line wherein the polymer dosage mixes with the coagulated waste water to produce and output flocculated waste water;
• a clarifier connected to the second flow line to receive the flocculated waste water and to produce sludge-free waste water and concentrated sludge;
• a filter feed tank to receive the sludge-free water from the clarifier;
• a filter press to produce treated water from the concentrated sludge;
• a pressure sand filter constructed to receive the sludge-free waste water and the treated water and outputs to a activated carbon filter and/or iron removal filter (CIRF);
• and
• an ultrafiltration system that receives CIRF-filtered water and outputs ultrafiltration-treated water to a reverse osmosis system,
• wherein a first inlet valve regulates the waste water flowing into the electrocoagulation unit, and
• wherein the electrocoagulation unit includes:
• a nonconductive outer shell having an interior space;
• a control unit electrically connected to the electrocoagulation unit;
• an electrocoagulation feed line connected to the first flow line, the electrocoagulation feed line including a plurality of electrocoagulation feed pipes connected to a bottom surface of the nonconductive outer shell to feed the waste water received from the first flow line into a lower portion of the interior space;
• an air grid controlled by the control unit;
• and
• an electrode assembly placed substantially within the nonconductive outer shell, the electrode assembly including a plurality of electrodes exposed to an upward flow of the waste water from the lower portion of the interior space, a plurality of holders to hold the plurality of electrodes, and an electrode lifting arrangement on a top edge of each of the plurality of electrodes,
• wherein the plurality of electrocoagulation feed pipes are spaced with respect to each other to allow the waste water to enter the lower portion of the interior space of the electrocoagulation unit evenly, and
• wherein the air grid purges waste material from the plurality of electrodes.
