Electro Coagulation (EC)
Also known as short wave electrolysis, is a technique used for water treatment wastewater treatment, industrial process water, and hospital wastewater. Electricity-based electrocoagulation technology is used to remove contaminants that are less efficient at filtering, microbiology or processing system with chemicals, such as oil emulsion, hydrocarbons from petroleum, suspended solids, and heavy metals without the use of chemicals.
Process of Electro Coagulation
EC System comes in a pre-packaged intermodal cargo container that sits above ground and can be located either inside or outside the facility. Pollutant removal begins when collected water in the system’s influent tank is pumped through a series of electrolytic cells. As water passes through these cells, it is exposed to a controlled electrical current and becomes charged, causing suspended contaminant particles to bond together and form larger masses.
The water is then transferred to a clarifier tank where lighter emulsified petroleum elements rise to the water surface and masses of heavier solids settle to the tank bottom. Separated contaminants are then pumped to a sludge accumulation tank while the clear phase of water is sent to a separator tank for removal of any remaining floc. The end result is clean water with fewer contaminants ready for reuse or for discharge to the sewer.
Advantages of Electro Coagulation
- Less processing fee (monthly cost)
- Land required is relatively small
- The execution / use very simple tools
- There is virtually no need of Chemical materials
- Able to process various types of liquid waste
- Less sludge generated from the process
- Risk of workmanship is very small
- Faster processing time
Frequently Asked Questions
What is Electro Coagulation (EC) and how does it work?
Electro Coagulation (EC) is an engineered water or wastewater treatment process selected to achieve a defined quality, recovery or discharge objective. Its operating principle and treatment stages depend on the application.
What contaminants or water-quality problems can Electro Coagulation (EC) address?
Performance depends on the selected configuration. Water analysis is used to identify suspended solids, dissolved salts, hardness, oil, organics, nutrients, metals or other parameters that the treatment train must control.
How is a Electro Coagulation (EC) system designed and sized?
Design uses flow and load profiles, laboratory analysis, target outlet quality, recovery, operating hours, redundancy, footprint, utilities, sludge or concentrate handling and lifecycle cost.
How much does Electro Coagulation (EC) cost in Singapore?
Cost depends on capacity, feed quality, materials, automation, civil and installation scope, performance requirements and ongoing consumables. A site-specific assessment is needed for a reliable budget.
Can World Technologies upgrade or maintain Electro Coagulation (EC)?
Yes. World Technologies can review existing performance and support suitable upgrades, equipment replacement, commissioning, troubleshooting, consumables and preventive maintenance.
