UTILITY WATER
Steam boiler, cooling tower, domestic hot water circuit, etc. Treatment of all these installations is necessary to keep them in good working order.
TRESCH Traitement des Eaux
implements complete utility water treatment solutions
Steam boiler
Steam boiler make-up water is systematically treated to prevent the precipitation of mineral salts under the combined effect of their concentration and the high temperatures encountered. The water is also chemically conditioned.
The make-up water for steam cycles is therefore systematically demineralised, to a greater or lesser extent depending on the boiler's operating pressure. Dissolved gases, oxygen and carbon dioxide, which are the main causes of corrosion, are advantageously eliminated by thermal degassing. Chemical conditioning of the circuit will complete these treatments in order to :
- eliminate residual oxygen
- sequestering and dispersing mineral sludge
- passivate heat exchange walls to control corrosion
- neutralise the carbonic acidity of condensate returns
Cooling tower
Cooling circuits are subject to many problems: scaling, corrosion, fouling and the development of micro-organisms. Treatment of the make-up water and the circuit water is necessary to solve these problems.TRESCH has developed a treatment principle for cooling water heaters and evaporative condensers that meets the regulatory requirements of the ministerial decree of 14 December 2013 to combat the development of legionella in this type of circuit. Drawing on its experience in this field, we can also provide support for the administrative aspects of these applications.
Domestic hot water
Sanitary water is used to produce hot and cold sanitary water, heating and air conditioning. Without additional treatment, the circuits and appliances in contact with this water sometimes suffer from serious problems such as corrosion, scaling, clogging or the development of micro-organisms that affect the efficiency and durability of the installations or pose a health risk (legionella, etc.).
