Water Treatment
Water Filtration Plant
A water filtration plant removes suspended matter and selected contaminants through a sequence of physical, chemical or biological treatment stages chosen for the incoming water and its intended use.

Why water filtration is required
Raw water may carry turbidity, sediment, colour, odour, microorganisms and dissolved constituents. The required treatment depends on the source, which may be groundwater, surface water, municipal supply or a process-water stream.
Commercial and industrial systems are configured around both average and peak flow so the filtration stages can provide the required service rate.
Typical filtration stages
- Screening or straining of coarse material
- Coagulation and clarification where fine particles need to be grouped and settled
- Pressure-sand or multimedia filtration
- Activated-carbon filtration for selected taste, odour and organic concerns
- Cartridge or bag filtration
- Iron removal, softening or membrane treatment where the analysis requires it
- Disinfection before storage or distribution where specified
Industrial filtration arrangement
Industrial plants may use several filtration stages in series so each unit protects the next. Pumps, vessels, valves and instruments are arranged for normal service, backwashing, cleaning and maintenance.
The plant can be fabricated as a skid-mounted package or assembled on site depending on the required capacity and available space.
Design inputs
- Raw-water laboratory analysis
- Required treated-water quality
- Daily volume and peak flow
- Available pressure and power
- Backwash and reject-water route
