Filtration Water Treatment

Used to produce drinking or process water, filtration water treatment processes ground, surface or wastewater using many technologies. These include fine mesh screening, media filtration and membrane filtration. Each method effectively separates solids from water.

What is Filtration Water Treatment?

Many industries need a constant stream of portable drinking or process water. For example, operations such as food manufacturing and automotive assembly uses process water, whilst sewerage treatment plants require effective wastewater filtration processes. 

Using filtration in water treatment, solid particles are entirely removed from the water. This can be from ground water, surface water or even pre-treated wastewater.

These processes in water treatment have a clear objective: to provide the correct quality of water for the specific industrial application.

The Filtration Water Treatment Process

Filtration is an important stage when treating water. Firstly, multiple methods of pre-treatment are common. This could include flocculation, coagulation and sedimentation. 

Following pre-treatment, various forms of water filtration can be used. For fine screening, drumfilters and discfilters are common. They remove suspended solids from the water and polish effluent from wastewater treatment plants.

Should media filtration be chosen, pressure gravitational filters can be used. These work by the media forming a barrier to the passage of suspended solids, absorbing some compounds contained in the liquids.

Finally, membrane technologies can be used. These include ultrafiltration, microfiltration, nanofiltration, and reverse osmosis. They will retain different sizes of particles and ions, whilst allowing pure water to flow through.

It is also wise to use water filter cartridges. Acting as protection barriers, they retain solids and particles upstream.
