Water Treatment Technology

---

Reverse osmosis (RO) is a water treatment process that removes ions, unwanted molecules, and larger particles from drinking water using a partially permeable membrane. As a result, the solute is kept on the membrane’s pressurized side and the pure solvent can pass to the other side.

Ultrafiltration (UF) is a water treatment process that uses a membrane technique that removes the dissolved and colloidal material at low transmembrane pressure. Dissolved metal ions as low-molecular weights or hydrated ions could send UF membranes because their membranes have pores that are greater than dissolved metal ions.

Ion exchange is a water treatment process often used for water softening or demineralization. It is also used to remove other substances from the water in processes such as dealkalization, deionization, denitrification, and disinfection.

Clarification is a wastewater treatment process to remove suspended solids through gravity settling, providing a clarified liquid effluent.  A secondary function of a clarifier is the removal of floating matter that has accumulated on the water surface. 

Flocculation and Coagulation in water treatment are used to remove suspended solids through a process that destabilizes the suspended particles in water solutions. The difference between the two is coagulation is the coming together, or clumping of particles, and flocculation is the settling of coagulated particles.

Media filtration is a type of filter process in which water passes through the filtration media to remove solids. 

Activated carbon filters are generally employed to remove organic compounds and/or extract free chlorine from water, making the water suitable for discharge or use in manufacturing processes.

Greensand filters are often used in an array of commercial and industrial water treatment applications to remove iron, manganese, hydrogen sulfide, arsenic, and radium.

UV radiation affects microorganisms by altering the DNA in the cells and impeding reproduction, killing them in the process. 

Ozone water treatment begins with the creation of ozone in an ozone generator. Ozone is injected into the water and immediately starts oxidizing and eliminating contaminants, such as bacteria, viruses, and metals. Ozone oxidizes organic material in the membranes of bacteria, viruses, and parasites.
