Coagulation process edit Coagulation is one of the most important physio-chemical reactions used in water treatment. In series cell arrangement, a higher potential difference is required for a given current to flow because the cells connected in series have higher resistance. Sodium hypochlorite can be generated electrolytically in an E cell using platinum and similar inert electrodes or by using external electrochlorinators. These treatment processes also tend to increase the total dissolved solids (TDS) content of the effluent, making it unacceptable for reuse within industrial applications." 6 "Although the electrocoagulation mechanism resembles chemical coagulation in that the cationic species are responsible for the neutralization of surface charges. Emulsified oil and grease cause damage to the media filters, resulting in very high maintenance costs. Consumable metal plates, such as iron or aluminum, are usually used as sacrificial electrodes to continuously produce ions in the water. This process also requires addition of compressed air for floatation of coagulated contaminants. It is important to note that electrocoagulation technology cannot remove infinitely soluble matter. "Electrocoagulation (cure) Treatment of Ship Bilge Water for the US Coast Guard in Alaska". The clear, treated (supernatant) water is typically then pumped to a buffer tank for later disposal and/or reuse in the plants designated process. Bleaching by the oxygen ions produced in the reaction chamber oxidizes dyes, cyanides, bacteria, viruses, biohazards, etc.

Al-Shannag, Mohammad; Bani-Melhem, Khalid; Al-Anber, Zaid; Al-Qodah, Zakaria. Reactions within the electrocoagulation reactor edit Within the electrocoagulation reactor, several distinct electrochemical reactions are produced independently. A large one-thousand gallon per minute cooling tower application in El Paso, Texas illustrates electrocoagulations growing recognition and acceptance to the industrial community. Dosing incoming waste water with sodium hypochlorite assists reduction of biochemical oxygen demand (BOD) and consequent chemical oxygen demand (COD) although this should be avoided for wastewater containing high levels of organic compounds or dissolved ammonia (NH4) due to formation of trihalogenated methanes (THMs). Ions (heavy metals) and colloids (organic and inorganic) are mostly held in solution by electrical charges. Marine Technology Society Journal. Electrocoagulation addresses any size of suspended solids (including destructive 30 m particles and heavy metals that can wear-and-tear pressure washers and pose an environmental and employee hazard). When connected to an external power source, the anode material will electrochemically corrode due to oxidation, while the cathode will be subjected to passivation. 1 third-party source needed, background edit. The aggregated flocculent mass settles either in the reaction vessel or in subsequent settling tanks due to gravitational force. Following removal to a friends qualities essay sludge collection tank, it is typically dewatered to a semi-dry cake using a mechanical screw press.
