AUTOMATED ELECTROCOAGULATION SYSTEM FOR WASTEWATER TREATMENT

There are two major ways to treat wastewater; it is either through chemical or non-chemical treatment. Both improve water quality, but do not make water safe for domestic use. Most firms or companies use coagulation treatment or chemical treatment. But the problem for this treatment is the selection of the best chemical to be used; it is expensive and frequent dosage adjustments are required to ensure good water treatment results. All coagulation chemical add specific elements to the water, improper doses and application generally pose problems (health risks). Hence, it requires extra preventive measures. A more cost-effective method to clean a wide range of polluted water on-site, and with minimal additives, is required for sustainable water management. Electrocoagulation treatment of water may fit this description [1]. Electrocoagulation is most widely used in other countries but not in the Philippines. Hence, the device readily available in the market is very expensive. The paper focuses on the automation of the Electrocoagulation process by using microcontroller, sensor, relays, and sacrificial anodes.
