Softening

By using softened water as make-up water, scaling in the cooling system can be avoided. The prevention of scale deposits also reduces the formation of Legionella bacteria in the system. The need for drainage of the water is minimized with softened water. Thereby, the solution is both economic and environment friendly.

 

When the water has certain hardness, we use softened water as make-up water. If the make-up water has a hardness above 1 °dH the water should be softened. For softening the make-up water we use a simple cation exchange plant. The softening will remove the hardness in the water which contributes to the formation of scale deposits in the cooling water system.

 

Scale deposits have several unfortunate effects. Scale encourages bacterial growth and reduces the heat transfer efficiency in the cooling system.

It is important to mention, that there are still considerable amounts of salt in the water after softening. These salts will be concentrated when the water is evaporated in the cooling tower/evaporation condenser. Therefore a blow down will still be necessary.

UniSoft 9000

Volume controlled softening filters in the Guldager UniSoft 9000 series are duplex plants, delivering treated water continuously 24 hours a day.

The advantage of volume control is that the fi lter spends its entire capacity before regeneration starts automatically. This means a reduction of the consumption of water and salt of 25% compared to a traditional time controlled plant.

The UniSoft 9000 series is delivered in 6 sizes with a capacity from 2000 – 15000 litres per hour. Our engineers are pleased to make individual calculations if special needs or consume patterns are to be taken into account. Guldager also delivers and projects time- and volume controlled simplex plants in all sizes. Capacity varying from 0,5 m³ to 200 m³ per regeneration at 20°dH, and a fl ow from 50 l/min to 500 l/min.

The UniSoft 9000 series is made of non-corrosive materials. In the regeneration process, soft water is used. This means a longer lifetime of parts exposed to abrasion.
