2. Water treatment - Wikipedia

   en.wikipedia.org/wiki/Water_treatment

   Typical drinking water treatment processes. Treatment for drinking water production involves the removal of contaminants and/or inactivation of any potentially harmful microbes from raw water to produce water that is pure enough for human consumption without any short term or long term risk of any adverse health effect. In general terms, the ...

3. Water purification - Wikipedia

   en.wikipedia.org/wiki/Water_purification

   Station for complex water treatment SKO-10K. One of the first steps in most conventional water purification processes is the addition of chemicals to assist in the removal of particles suspended in water. Particles can be inorganic such as clay and silt or organic such as algae, bacteria, viruses, protozoa and natural organic matter.

4. Flocculation - Wikipedia

   en.wikipedia.org/wiki/Flocculation

   Flocculation and sedimentation are widely employed in the purification of drinking water as well as in sewage treatment, storm-water treatment and treatment of industrial wastewater streams. For drinking water, typical treatment processes consist of grates, coagulation, flocculation, sedimentation, granular filtration and disinfection. [16]

5. Reverse osmosis - Wikipedia

   en.wikipedia.org/wiki/Reverse_osmosis

   This hybrid process reduces treatment cost significantly and lengthens membrane life. RO can be used for the production of deionized water. [20] In 2002, Singapore announced that a process named NEWater would be a significant part of its water plans. RO would be used to treat wastewater before discharging the effluent into reservoirs.

6. Sand filter - Wikipedia

   en.wikipedia.org/wiki/Sand_filter

   Sand filters are used in various sectors and processes, where far-reaching removal of suspended matter from water or wastewater is required. Sectors where sand filtration is implemented include drinking water production, swimming pools, car washes, groundwater treatment, RWZI, slaughterhouses, fruit and vegetable processing industry, drinks ...

7. Coagulation (water treatment) - Wikipedia

   en.wikipedia.org/wiki/Coagulation_(water_treatment)

   Coagulation-flocculation process in a water treatment system. In water treatment, coagulation and flocculation involve the addition of compounds that promote the clumping of fine floc into larger floc so that they can be more easily separated from the water. Coagulation is a chemical process that involves neutralization of charge whereas ...
