Highly Purified Water

HPW systems for the preparation of purified water according to PhEur/USP are being delivered as pre-qualified compact plants, ready for connection. The compact package unit construction technique on a stainless steel skid provides all the required processing technologies, which will be adapted specifically to the prevailing quality of the potable water. In addition to special techniques of drinking water conditioning in individual cases, e.g. upstream ultrafiltration, every pre-qualified compact plant with a performance range from 100 to 25,000 LPH is composed of the following components:

  • double softening, serial connection, quality-controlled, alternative conditioning according to the drinking water ordinance (TVO)
  • recirculation system UV plus
  • reverse osmosis, single- or double-stage construction
  • optional membrane degasification for the reduction of CO2
  • electrodeionization CEDI
  • ultrafiltration 6,000 dalton optionally with integrated automatic membrane testing
  • optional hot water sanitizing at > 80 °C or chemical sanitization
  • pipes of stainless steel 316L, Ra<0.50 µm, orbital welding, alternatively PVDF-HP with bead and crevice-free welding, Ra <0.20 µm
  • latest control technology Siemens S7 PLC controller with touch panel or panel PC
