What is turbidity removal from water?

Turbidity removal is the process of reducing suspended and colloidal particles that make water appear cloudy or hazy. Depending on the water quality and required outlet standard, treatment may include coagulation, flocculation, sedimentation, filtration, or membrane treatment.

What causes high turbidity in water?

High turbidity can be caused by silt, clay, suspended solids, algae, microorganisms, organic matter, colloids, corrosion products, and industrial contaminants. Surface water can also experience significant turbidity increases during heavy rainfall and monsoon periods.

What is a good turbidity level for treated water?

The required turbidity level depends on the application. Drinking water generally requires very low turbidity, while industrial applications such as cooling towers, RO pretreatment, and process water may have different specifications.

How is turbidity measured in water?

Turbidity is commonly measured in Nephelometric Turbidity Units (NTU). A higher NTU value indicates a greater concentration of light-scattering particles and therefore cloudier water.

How can turbidity be removed from industrial water?

Industrial turbidity can be treated using coagulation and flocculation, sedimentation, multimedia filtration, microfiltration (MF), or ultrafiltration (UF). The appropriate technology depends on particle size, turbidity level, flow, and the required treated-water quality.
