Water purif.unit,skid,15cbm/hr@30m,TMH

General Description:
Water purification unit, skid mounted with a capacity of 15 cubic meters per hour at 30 (TMH) Total Manometric Head.

Technical Specifications:
The unit is designed to purify 15 cubic meters per hour at 30 TMH of surface water from rivers, lakes or shallow wells having maximum turbidity of 20 (N.T.U.) Nephelometric Turbidity Units.
The unit is capable of producing drinking water free of the physical and bacteriological contaminations.
The unit will not take care of industrial contamination, such as hydrocarbons, chemical waste, etc.
All material used in the unit that are in contact with water should be of approved food grade quality.
All the operations of the unit are controlled by a robust control panel including the start/stop switches and all the controls and metering.

The following steps are followed in the water treatment process:

1. Raw water suction and straining: This is done by a submersible pump complete with the suction hose and inlet strainer of approximately 2 mm openings.
2. Coagulation by Aluminum Sulphate; this includes the tanks and equipment for the preparation of the solution and dosing of the predetermined amount of sulphate.
3. Pre-chlorination by Calcium Hypochlorite; this includes the tanks and equipment for the preparation of the solution and dosing the predetermined amount of Hypochlorite.
4. Sedimentation; this allows for a contact time of about one hour for the chemicals to react and the solids to settle. The sedimentation chamber should have all the facilities for the periodic removal of the sediments as well as passing the clarified water to the next stage of treatment.
5. Filtration; this includes a sand filter, an activated carbon filter and a micro filter (might be as an optional). The filters are complete with all the automatic back wash piping, valves, manometers and controls.
6. Disinfection; this could include an Ultra Violet treatment or Chlorination. In both cases a dose of residual Chlorine is added to guard against subsequent contamination during storage.
