Public swimming baths

Vannkanten For public swimming pools we can supply a number of partial solutions. We do not project swimming baths but supply all the technical equipment that will make a swimming bath well-functioning.

We have metering units for correct dosage of chlorine etc. We have measuring and testing equipment for monitoring of the water quality, and we can supply filters for cleaning the water. UV disinfection of water is one of our specialities.

Furthermore, we have a special product that prevents lime from depositing in installations and sprinkling roses.

Car washing plants

Bilvaskehal For the past years HOH has been a supplier to the car washing market, both in Denmark as well as abroad. This has given us knowledge about car washing which we have utilised for constructing a series of plants aimed exactly at this segment.
The water treatment plants are based on reverse osmosis technology, which removes all salts, and have a softening unit as pre-treatment.
The plants consider the requirements made at service stations and by machinery suppliers like e.g.:

Quick and simple installation
Very small built-in measures
Reduced operating expenses compared to existing RO plant:
- Electricity reduction: 65%
- Water reduction: 100%
- Salt reduction: 25-30%

Fountain plants

Spejlbassin A typical water-treatment plant for a fountain may consist of:

A surge tank that can pick up the amount of water which returns in case of a stop.

Fresh-water connection to the plant. If the water contains too much lime or there is a great evaporation, it will be convenient to connect a desalination plant.

For sorting out particles in the water in order to avoid blocking you may connect a bag filter or sand filter dependent on the water amount, impurities and whether there is water for backwashing of the sand filter.

Organic fouling, bacterial growth, algae and the like will almost always occur in fountain water, but it may be prevented by dosing with chemicals or UV-illuminating the circulation water, depending on whether it is an indoor or outdoor water arrangement. It is also of importance which material the fountain is made of.

Laundries

Vask We have developed a special plant for laundries which supplies soft water to the washing machines. The capacity corresponds to the consumption of approx. 5-6 industrial machines.

The plant is suitable for apartment blocks with common laundries, co-operated laundries, institutional laundries etc.
