Salts


Proceeding elimination of salts at too high silicic acid concentrations

Ultra Pure Water Filter
is connected after a reverse osmosis unit

eliminates e.g. silica if a reverse osmosis unit rejects not enough of it


Adding substances
Mineral Filter for harden up the water
(e.g. for reverse osmosis units)
enriches the water with calcium and alkalinity (carbonat hardness)

Monitoring of R.O. units
Pressure gauges

Shows the operation pressure of a R.O. unit: if the pressure decreases the pre-filter is maybe blocked.
Filter check Shows the function of the pre-filters: green display = filter o.k.; red display = filter is blocked
TDS stick Shows TDS (total dissolved solids) of permeate and feed water; you can calculate the exact rejection of the R.O. unit
Conductivity meter for permeate
Measures the electrical conductivity of the permeate of a R.O. unit or a ultra pure water filter


Automation of R.O. units
R.O. control
1. Automated fill-up of a pressure-less tank (level control)
2. Automated flushing for better membrane performance
3. Standby-flushing to prevent fouling


Pumps for pressure raising (booster pumps)
Low voltage types Very silent pumps for small units (max. 40-50 l/h permeate flow)
Professional roto vane pumps Professional pumps for larger units, 100 to 1000 l/h feed flow
