Regardless with which water-consuming industry we are concerned, the use of rainwater as supplementary water instead of fresh water makes good sense.
Nevertheless, it should be remembered not to simply feed the rainwater into the water circuit. Here there lurk innumerable risks that can adversely affect the downstream processes. If the rainwater storage capacity is sufficiently large, FARITEC offers the possibility of using disk filtration or the ASC process to process the rainwater to the point where it can be safely fed into
the water circuit.

Osmosis Water from Rainwater

Up until now it has not been possible to produce osmosis water directly from rain water as the osmosis membrane is very sensitive.
We have optimized the polymer composition of the ASC system so that now elements down to a size of 5µm can be filtered out of the water. Through this we have so increased the purity of the rainwater that it can be directly applied to the reverse osmosis system and the sensitive membrane is protected against damage. An upstream softening plant is no longer required. With this system we were awarded the Green Directory award at Automechanica.

Save Resources

In addition to the economic advantages, the use of rainwater instead of fresh water and the use of a biological process water treatment system is a further important step towards the ecologically meaningful operation of vehicle washing systems.

In Comparison

From 100,000 litres of rainwater, 70,000 litres of osmosis water are obtained
Up until now, approx. 115,000 litres of fresh water have been needed for 70,000 litres of osmosis water

Benefits Faritec

The professional planning of the FARITEC biological process water treatment plants covers the water in your process chain from the first to the last drop. In the FARITEC Technical Product Design and Facility Engineering Department, detailed plans are drawn up for each project individually so that architects and builders can always discuss and plan all construction phases quickly and cost effectively.

Because every project is different in its cleaning requirements, we analyse the process water requirements in your construction projects. FARITEC supports you from the idea via the implementation right up to the day-to- day operation of your plant. During the construction of car washes and industrial plants, FARITEC works closely together with local partners at the appropriate interfaces.

FARITEC products are future-oriented, sustainable and reliable. The FARITEC process water treatment plants combine a long service life with low operating costs.

The technical products and further developments of the biological process water treatment and other products from FARITEC are practically tested under the conditions of real car wash operation in the washing facilities and self-service areas of BlueWash. So you, as our customer, have the assurance that you have a biological process water treatment plant which has been developed from practice for practice.
