Compact water softening equipment – “COMPACT-SOFT”


~ Softens water

~ Reduces iron

~ Reduces ammonium ions

~“COMPACT-SOFT” series equipment characteristics:

This equipment purifies the water from various chemical impurities. Mostly, this equipment is used for water softening, but in addition the equipment also reduces the iron, manganese and ammonium ions in the water.

The “COMPACT-SOFT” series treatment equipment are more suitable for private and commercial facilities, where not only high water quality requirements are decisive, but also visual appearance. The equipment has an attractive visual appearance and is compact, as the equipment and the reagent refill tank are combined in one hull.

~ Brief principle of equipment operation:

The pressure tank of the water treatment equipment is filled with a cation exchange layer. This layer attracts calcium, magnesium, iron, ammonia, and other ions from the water flowing through the tank. The amount of untreated water (m³) flowing through the layer in the tank gradually reduces the performance of this layer. And therefore this layer must be renewed periodically. Regeneration occurs automatically by rinsing the layer with saline. This is called filter regeneration. Elements accumulated during regeneration (Ca, Mg, Fe, etc.) are rinsed into the sewerage system. When the rinsing process is over, the equipment is ready for operation again. The device operates in automatic mode by means of a control mechanism.

The control mechanism is fully equipped with the necessary functions to be able to accurately adjust the settings individually required for each customer, based on the results of water analyzes, water pressures, etc. The control mechanism is equipped with a water consumption meter, which provides the recovery interval of the equipment (the number of liters until the next recovery), thus ensuring the consumption of reagent "Salt" and wastewater.

~ Additional benefits of using “COMPACT-SOFT” purification equipment:

  • Visual appearance
  • Unlike standard equipment, where the treatment tank is separated from the reagent tank, no condensation formed on the surface of the equipment due to the combined housing.

~ Water purification capacity:

  • Desired maximum total hardness (H) concentration in water for treatment - max. 30 eq-mmol / l.
  • Desired maximum concentration of iron (Fe) in water for treatment - max. 3 mg / l.
  • Desired maximum concentration of ammonium (NH4 + -N) in water for treatment - max. 5 mg / l.

~ Water treatment level:

  • Concentration of total hardness (H) in purified water after treatment - <0.5 eq-mmol / l.
  • Total iron (Fe) concentration in purified water after treatment - <0.2 mg / l.
  • Total ammonium (NH4 + -N) concentration in purified water after treatment - <0.5 mg / l.

~ Equipment treatment capacity and flow rates:

The required equipment must be selected on the basis of the results of water analyzes and the required treatment capacity.

Note! Treatment capacity is not equipment flow rate. The flow rate of the equipment is generally much higher than the treatment capacity (see table below).

Note! At times when the water consumption is higher than the treatment capacity shown in the table below, the water treatment function will still be performed, but the degree of treatment will gradually decrease depending on the amount of water consumed at the time.

Modeli Equipment treatment capacity Maximum flow
COMPACT-SOFT-17 0,6 m³/h (10l/ min) 5,0 m³/h
COMPACT-SOFT-35 0,9 m³/h (15l/ min) 5,0 m³/h

~ Equipment assemblage and manufacturers:

SIA "Ūdens būve" performs full equipment assembly. The equipment is assembled in the workshop of SIA “Ūdens būve”, 87 Kalnciema Street, or, if necessary, in the facility.

The components are of high quality, they have been inspected and tested. Manufacturers and suppliers of equipment components are the leading leaders in this field, which we believe is trust, responsibility and quality.

The most important components of the equipment are the control mechanism and the ion exchange material. With 10 years of experience in water treatment, we are convinced that the highest quality mechanisms are manufactured in the USA by Clack Corporation, while softener fillers are manufactured in Germany by Lanxess.
