Filtration of water with very high particle contamination

The BOLLFILTER automatic Type 6.18.2 Heavy Duty is a backwashable, self-cleanable strainer, which has been designed for filtering water with high particle contamination. Typical fields of application for this BOLLFILTER are non-prefiltered river water and highly fibre-laden process water.

Function of the BOLLFILTER Automatic 6.18.2

The principle behind it: Dual filtration, dual flushing!

The proven principle of dual filtration (where cross and counterflow backflushing is generated) has been supplemented by an efficient dual backflush function. The elements are open at both ends allowing the water to flow through from each end. Due to their length and increased diameter, their filter surface area is especially large.

Advantages of the BOLLFILTER Automatic Type 6.18.2

  • High performance in high particle contaminated applications
  • Defined filtration degree
  • Low operating cost due to low maintenance and long service life
