Specialist Water Treatment Plant

To get the water in accordance with the specifications and quality of the water industry as boiler mesinwater, cooling tower water, the water needs to be held the first cleaning. The clean can be a way of physics and chemistry.

a. The goal of treatment is physical:
• The separation of coarse solids.
• The separation of suspended solids and floating.
• Separation of fat.

b. The goal of treatment is chemically:
• The deposition of substances – substances that are dissolved using coagulant.
• Eliminate toxic substances and seeds – seeds of disease.
• Eliminate baud’s taste.

Tertiary Treatment:
– Sand filter
– Ultra filtration (UF), Micro Filtration (MF)
– Reverse osmosis (RO) water treatment last before use.
– Carbon filters, eliminate color and odor.
– Ultra violet (UV) light, eliminate bacterial pathogens.
– Chlorine dosing, Chlorines end.

Pretreatment Functions:
Filters                                      : Suspended Solids
Softener                                  : Hardness (Ca, Mg)
Dealkalizer                              : Hardness and alkalinity
Reverse osmosis                     : Most of the dissolved solids
Demineraliser                         : Maximum dissolved solids
Dearator                                 : Dissolved gases (oxygen, carbon dioxide).

Key issue: Steam, BFW and Make Up Water Quality.
– To meet purity steam, BFW quality should be as good as steam
– To meet BFW quality, the make – up water quality should be as good as BFW
– Steam Purity = BFW Quality = Make -Up Quality
