Mixed bed resin for the production of ultrapure water
Ultrapure water quality
Production of demineralised ("distilled") water with the following requirements:
- Conductance: 0 - 4 µS/cm *
- TDS: 0 - 2 ppm
- Carbonate hardness: 0 °d KH
- Total hardness: 0 °d GH
- Silicate / silicic acid: 0 g/mol
Our mixed-bed resin is preferably used in empty housings or plastic cartridges and is used to supply ultra-pure water in laboratories, surgeries and wherever particularly pure water is required. The industrially manufactured mixed bed resin consists of a mixture of 40 % cation resin and 60 % anion resin in order to achieve the highest possible yield of ultrapure water.
The resin is therefore perfect for water treatment in marine aquariums and as a silicate filter after reverse osmosis.
Capacity
One litre of mixed bed resin (approx. 660 g) of the type LanXess Lewatit has a capacity of 1500 hardness titres (HL) and thus produces the following quantities of ultrapure water. At
- 5 °d GH 300 litres
- 10 °d GH 150 litres
- 15 °d GH 100 litres
- 20 °d GH 75 litres
Downstream of a reverse osmosis system, a cartridge filling of the mixed bed resin can almost completely remove the residual salt content from up to several thousand litres of water.
Filling a standard filter cartridge in a 2.5 inch × 10 inch filter housing with resin requires approx. 430 - 435 g, which corresponds to approx. 660 ml.
* According to our own measurements, standard "distilled" or demineralised water from the supermarket or DIY store has a residual conductivity of at least ~ 8 - 10 µS/cm
