Waste Water Treatment Using Electro Coagulation

Work in progress

Definitions

Electrode	An electrode is a metallic contact through which the current can pass.
Total Suspended Solids (TSS)	Solids in contaminated water that can be trapped by filtration processes.
Colloids	Colloids are mixtures that have insoluble particles that are larger than a molecule but smaller than particles that can be seen with naked eye.
Turbidity	Turbidity is the cloudiness or haziness of a fluid caused by suspended solids that are usually invisible to the naked eye. The more total suspended solids in the water, the murkier it seems and the higher the turbidity. Turbidity is considered as a good measure of the quality of water.
Sludge	Semi-solid material that is produced as a by-product during sewage treatment of contaminated water.

Electro Coagulation

Electro Coagulation is a process of separating impurities, hazardous chemicals and bacteria from contaminated or waste or dirty water to make it reusable again. The byproduct of this process is called sludge and can be disposed off or reused for other purposes.

Electrocoagulation is performed by applying an electric current across metal plates (electrodes) that are submerged in contaminated water.

Contaminated water consists of suspended particles called colloids. In contaminated water, these particles can be organic particles like germs, bacteria, algae, and inorganic particles like clay, silt or hazardous chemicals. Almost all colloids have negatively charged surfaces. These surfaces attract positive ions in the water to the colloid surface. These positive ions form a layer around the colloid.
