from 220,71 

Clear

Models WITHOUT booster pump 

Equipment / scope of delivery:

  • Assembled ready for use
  • Tested for liter performance and retention
  • Manual flush valve with easy lever changeover
  • Optimally adjusted ultrapure to wastewater ratio
  • Fine and activated carbon filters
  • Inlet and outlet hoses of 100 cm length
  • Faucet connection for 3/4 “(standard)
  • Operating instructions and warranty card

Operating parameters:

  • Water pressure: 3 to max. 6 bar
  • Water temperature: min. 5 ° C to max. 40 ° C
  • Max. Water hardness: 22 ° dKH and 33 ° dGH
  • Salinity max .: 2,000 mg / l
  • Ultrapure to waste water: 1: 3 (up to 1: 3.5)

The devices are not suitable for treating well or groundwater with an iron content of more than 0.1 mg / l. The dissolved iron precipitates as insoluble iron oxide sludge on the membrane surface and makes the membrane unusable.

Outstanding hw membrane quality with tested performance data

All hw reverse osmosis systems are equipped with a hw flushing valve as standard, which has been optimally adapted to the respective membrane in the factory. After performing a rinsing process, it is ensured that the hw reverse osmosis system is always operated in the optimal ultra-pure to waste water ratio (1: 3 to 1: 3.5). Accidental misalignment and the associated damage to the membrane is therefore excluded.

How hw® reverse osmosis systems work:

The hw reverse osmosis is a natural and environmentally friendly process to physically remove dissolved salts and pollutants from the water. In this process, the water in the household supply is pressed against a semipermeable (= semi-permeable) membrane by the tap water pressure (2 to 6 bar). During this process, only the purest water can penetrate the membrane of the hw reverse osmosis system, salts and pollutants as well as impurities are reliably retained by the membrane and discharged together with the residual water (concentrate).

The water obtained in this way is ultrapure water (permeate) and, except for the slightest traces that can hardly be traced, is free from harmful impurities. The largest part (95% -99%) of the pollutants dissolved in the tap water cannot penetrate the membrane.

All hw® reverse osmosis systems are equipped as standard with an hw flushing valve, which has been optimally adapted to the respective membrane in the factory. After performing a rinsing process, it is ensured that the system is always operated in the optimal ultra-pure to waste water ratio. An accidental misalignment is excluded.

The heart of all hw® reverse osmosis systes:

The hw®-TFC polyvinyl membrane

hw® reverse osmosis systems are exclusively equipped with a unique, fully synthetic membrane, the hw®-TFC polyvinyl membrane. It far exceeds conventional membrane types (acetate, triacetate or polysulfone membranes) in terms of stability and retention. This membrane consists of a fully synthetic material developed exclusively for hw®, which can be used with conventional membrane types, e.g. Acetate, triacetate or polysulfone membranes, far outperforming. This means that the hw®-TFC polyvinyl membrane cannot be attacked or even eaten by bacteria, even when it has been down for several weeks (up to 3 months!).

The hw® reverse osmosis systems tolerate salt contents of up to 2,000 mg per liter and are insensitive to carbonate hardness up to 22˚dKH and insensitive to chlorine concentrations up to 1 mg per liter of raw water.
