River Water Treatment

River Water Treatment

When the location of the plant is far from the sea, a very common source of water is from rivers.

River water contains salinity, hardness, total suspended solids, organic matter, algae content, which are not suitable for the industrial service such as: irrigation, feed steam boilers or others.

PSC S.r.l. Engineering & Contracting (PSC) is able to provide any process solution for the treatment of river water.

Here below is described a possible the following flow scheme treatment:

  • Grit and sand separator to remove coarse solids as sand and grit material (this depends on the river water quality and intake design);
  • Chemical disinfection to reduce the bacteria content and to chemically oxidize some organics by means of chlorine injection;
  • Coagulation and flocculation process required to improve the efficiency in the settling and filtration of the suspend solids and colloidal matter, by chemical injections;
  • Lime softening to reduce the total hardness, suspended solids, colloidal and organic matter by chemical precipitation;
  • Settling clarifiers or dissolved air flotation to remove suspend solids, turbidity and some organic, algae. Sometimes a chemical softening is also required;
  • Granular filters (pressure or gravity type) or UF filtration membranes for total removal of very fine suspended solids, for turbidity reduction, bacteria (the selection depends on the river inlet characteristics);
  • Brackish reverse osmosis, a hyper filtration membrane process to get desalinated water and without organic;
  • Electro- deionization process based on electrodialysis and mixed bed ix -exchange resins to achieve ultrapure water quality;

The treated water can be used for drinking purposes, for irrigation and other industrial services.
