Demineralized water (water without minerals) has a broad appliance in the households as well as in the industry. Most appliance of the demineralized water is in the:

• distilleries (for attenuation of alcoholic drinks),
• pharmaceutical industry
• laboratories,
• chemical industry,
• accumulators, the irons…

     DEMINERALIZATOR is a device that consists of two filter columns, cat ion and anion, with filter filling that removes minerals from the water. Water gained after anion column has 1-5 µS electro conductivity. To gain absolutely clean water with 0-1 µS electro conductivity we must install the third column so-called mixed column (column for fine polish).

Manual demineralizator

     Cat ion and anion column are regenerated after satiation, while in the mixed column there is a replacement of filter filling. Working life of ion exchanger filling of demineralizators is from 3 to 5 years, after which it must be replaced. If drinking water consists of iron, pretreatment must be done.

     Reference: Contingent upon the buyer’s need you can manage demineralizators manually (by valves) or automatically.

Schematic view

     The hardness of the water is made by carbonates and sulfates of Ca and Mg. To prevent the lime scale of appearing in the boilers and process equipment, water is subjected to the treatment called softening, and the filters used are called SOFTENERS.

     The filling of the softeners is ion exchange resin which work principle is bounding the ions of Ca and Mg, which prevents the creation of the lime scale in the process. So, softeners work on the ion exchange principle.

Automatic softeners

The softeners are used in water treatments applied at the following purposes:

• the preparation of boiler water,
• the preparation of water for the cooling system,
• the preparation of water for washing and scavenging,
• in all the cases where there is needed removing the hardness of water.

PRACTICAL EXAMPLES AND ECONOMICAL BENEFIT WE GET BY USING THE SOFTENED WATER:

• ~ 50% of detergent and soap saving
• ~ 30% less clothes chafing
• ~ 60% of power consumption for hot water heating*
• ~ 90% of saving on the repairs and replacement of the apparatuses and parts**

* 2 mm of lime scale coating on the heater
** boiler-room, boiler, dishwasher, washing machine, water taps, pumps, heaters…

     Reference: Contingent upon the buyer’s need you can manage the softeners manually (by valves) or automatically and they can be duplex or mono based.

     Arsenic is widely spread in the Earth’s crust up to 40 mg/kg in quantity. It is used in all of the glass industries, wood impregnation, in agro chemistry as tecnazene and herbicide and also can be found in detergents, etc. They are also the biggest water pollutants, as well as the fossil fuels that, also, contain some amount of arsenic.

     The process of arsenic removing is called DEARSENIZATION. Filter filling is a selective filter mass for arsenic removing with the next characteristics: small specific weight, high useful capacity, not regenerative, there is a possibility of disinfection.

     You can find hydrogen oxide sulphide in the water, especially from deep underground water. It is created due to the bacteria activity during the disruption of organic matters. Hydrogen oxide sulphide is in the all waste water, and it originates due to microorganism activity on the sulfates in the water.

     Removing it is a routine procedure managed by filtration through the filter with a special filling for removing hydrogen oxide sulphide. Filtration control is done by automatic valves.
