Drinking Water Treatment - Filtration: Save water and energy, and improve filter performance 

Monitoring turbidity of filter effluent is required for regulatory compliance and helps to assure that the delivered water is safe for public consumption.

In addition to meeting regulatory requirements, monitoring turbidity is also beneficial for optimisng filter performance, establishing filter backwash cycles, and detecting filter breakthrough.

Turbidity instrumentation is available to meet the unique needs of both conventional and membrane filtration facilities.



SOLITAX sc: for higher turbidity influent and backwash

High-precision turbidity probes determine turbidity according to DIN EN ISO 7027 and are certified according to MCERTS regulation.
  • Measurement range: 0.001 – 4000 FNU (NTU)
  • Time saving - no calibration
  • Proven automatic cleaning system prevents erroneous values
  • Maximum variability – plastic or stainless steel housing, with or without wiper cleaning system, immersion or insertion mounting
  • Fully serviceable probes for prolonged service life
