Processes
- Coagulation/Filtration
Coagulation/filtration is a process that removes contaminants from water by precipitation. Aluminum salts and ferric (iron) salts are the two most commonly used coagulants in the water treatment industry. These salts work by hydrolyzing to form aluminum hydroxide and iron hydroxide particulates, which can then be effectively filtered out.
- Oxidation Filtration
- Flocculation/Clarification
The flocculation/clarification process is applied when there is a high degree of turbidity in the water or when solids must be separated from liquids. Flocculation/clarification is highly effective at reducing turbidity and removing color, solids and colloidal material from water and wastewater.
- Adsorption
Adsorption is a process where contaminants break their bond with water molecules and chemically adhere to a filter media. Adsorption is a constant process where water is directed at a specific flow rate through a fixed bed of adsorption media for a period of six months to two years until exhaustion.
- Dewatering Process
- Membrane Filtration
Membrane Filtration is the process of membrane filtration uses pressure to force a carrier fluid, such as water, through a semi-permeable (porous) membrane in order to separate suspended particulate matter from the fluid and soluble components.
- Ion Exchange
- Chemical Treatment
