Water treatment for private water supply

Product catalog summary

Introduction
This document discusses effective and cost-efficient solutions for water treatment in private water supplies, focusing on maintaining hygienic standards.

Microbiology and Disinfection
Ultrafiltration is highlighted as a key disinfection method, using membranes with a separation capacity of less than 0.01 µm to retain germs, viruses, and bacteria. This method acts as a barrier between polluted and pure water and is not affected by raw water quality fluctuations. A backwash process is necessary to clean the membranes.

Three disinfection processes are available: chemical disinfection with chlorine dioxide, UV light irradiation, and ultrafiltration. GENODOS® DM-B/DM-BO dosing systems with GENO®-Baktox can be used for continuous dosing to eliminate germs. UV disinfection uses a special lamp to kill germs with a germicidal effect of over 99.99%, but lacks a depot effect.

Deacidification, Deferrisation, and Demanganisation
Ground or well water may have low pH values due to excess carbon dioxide, which can corrode metal pipes. Deacidification can be achieved by dosing lye or using calcium carbonate. Iron and manganese in water can cause discoloration and stains. Deferrisation and demanganisation can be done using potassium permanganate or catalytic filter material, depending on concentration levels.

Nitrate Reduction and Salt Concentration Reduction
Nitrate levels can be high in areas of intensive farming. Ion exchangers are used to reduce nitrate concentrations by replacing nitrate with chloride. Reverse osmosis is used to reduce total salt concentration, especially in coastal areas, by using a semi-permeable membrane to separate solutions of different concentrations. This process also reduces bacteria, germs, and dissolved organic substances.

Conclusion
The document emphasizes the importance of water treatment in private systems to comply with drinking water standards and prevent damage to infrastructure.

In large water supply companies, for instance, costly measuring and control technology is installed for this purpose. In the comparatively small systems used for private water supply, however, other processes must be applied in order to render the water treatment cost-effective. The water originating from private supply systems requires treatment if one or several substances contained...

Such low pH values result from an excess of carbon dioxide. In terms of hygiene or health, there are no objections to purely use acidic water as drinking water. For technical applications, however, this kind of...

In areas of intensive agricultural manuring, however, nitrate values of > 50 mg/l can be found. In this process, nitrate is replaced by chloride (similar to the softening process where calcium and magnesium are replaced by sodium). When the ion exchange material is exhausted, it will be regenerated fully automatically. In general, ion exchangers...
