Required Data
- maximum needed flow
- minimum available flow for backflushing
- minimum and maximum working pressure
- origin and quality of raw water
- space availability
- availability of electrical power
quality of raw water (indication: suspended particlesl in Milligramm pro Liter / TSS)
- light soiling: (clear river water) 0 – 50 ppm
- normal soiling: (muddy water) 50 – 100 ppm
- heavy soiling: (very murky water) over 100 ppm
- for water with particle loading over 300 ppm upstream sedimentation tank required (eventual in combination with flocculants or self-cleaning pump pre-filters)
- for water with sand content upstream hydrocyclone (separator) recommended
- the information in tables relates to maximum filtration velocity of 50 mtr/m²/h (for optimum filtration quality lower filtration velocity should be assumed)

Modularity
Due to modular assembly of multiple filter container with automatic valves, amounts of water up to scores of 1000 m³ per hour are realizable even with poor water quality. Automatic pressure difference controlled backflushing ensures continuous operation. Especially suitable for mobile plants owing to modularity and low weight.
