Rock forming silicates constitute 30% of the crust of the earth and are more important to carrier of ba-sic and surface water. Unfortunately, these substances can be removed inadequately too during applica-tion of a reverse osmosis only (support guess osmosis only approx. 85%, conductance 35 approx. micro Siemens, run out water SI 1800 below 1 Mikrosiemens!). Since no negative physiological effects are confessed for the human being in the case of the example of silica, no tolerance or standard values are available for drinking water. A content from 10 mg/l SI and more is even recommended for the forma-tion of corrosion-inhibiting SiO protective layers in drinking water pipelines!

In fields with silicatefree rocks (limestone areas) are hard ones water usual with extremely low silicate contents. Rock attacking source waters standing often under pressure and the very most have to 2000 mg/l Si! The silicate content of the seas transport in the deep water zones to 4 mg/l, however, are due to initial water through organisms (dinoflaggelates, radiolaries, diatomics and sponges) in upper and coast zones in the virtually not perceptible field.

It is possible with the filter pure water filter SI 1800, through selective revocation of remaining pollut-ants a micropure water of highest quality in a simple manner here deliver. The module is post-connected to the reverse osmosis where its outlet tubing is connected to SI 1800 (it results no pressure noxious for osmosis). In this way also let for itself open resultant sea water tank with relatively high rate of evapo-ration without problems without grease algae caused by remaining pollutants with all of them from it negative results (growing over invertebrates, redox drop etc.) operate. That it is grease algae caused by silica are main food source of red planarias to be known importantly in this connection also!

The substrate used is based on the newest stage of development of micropure water engineering and is inserted e.g. for micropurecleaning after traditional full desalination plants for the backup of hyperpure water. Depending on range, upper limits required here exist from a maximum of 0,002 mg/si/l!

The pot live of a filling is dependent on throughput, silicate and carbonic acid salary of the inlet water and conducts approx. 4 months during use of osmosis water and a withdrawal of 5 l daily. For control of conductibility is a connection available for a conductibility feeler. The filling can be regenerated in the factory, the cartridge is replaced simply with a new one.
