About us Using the chemical and bacteriological water analysis as a starting point we are putting together an assemblage of filters which alter the water to meet the pure water chemical and bacteriological standards according to the “REGULATIONS FOR HYGIENIC PURITY OF THE CONSUMABLE WATER” in Serbia and Montenegro and in accordance with all currently implemented EU directives and standards for consumable water, natural mineral water, bottled water, technical water and water intended for other purposes.
Filtration is the process in which certain chemical substances or the substances which are present in the concentration higher than required are removed. Consumable water coming from the public water supplier often doesn’t possess acceptable quality.
Most common impurities found in the untreated water are:
- gases (nitrogen, oxygen, ammonia)
- suspended particles (herbal residue, alum silicates)
- dissolved salts (both salts that make water hard and the ones that)
- organic components (humus substances, organic acids, microorganisms)

Common problems are:
- higher organic matter concentration in the water or substances of organic origin
- higher than permitted concentration of bacteria and viruses
- higher than permitted iron and manganese concentration
- higher than permitted arsenic concentration
- nitrate and nitrite concentrations are above the legal limit
- higher than permitted water hardness
- mechanical particles – sand, microscopic floating matter

Activated carbon filters
Activated carbon filters can successfully remove chlorine, organic matter and unwanted smells therefore lessening the muddiness and making the water crystal clear.
Activated carbon becomes saturated with waste matter so it needs to be changed occasionally.
Carbon replacement period depends on the water quality and generally an activated carbon should not be replaced sooner than 6 months into its use. Water filtration typically requires activated carbon treatment. Maintenance is very simple and it’s performed sporadically. Activated carbon degrades faster when used to filter low quality water. Water analyses can indicate the activated carbon anticipated life span in the filter. Each filtration assembly should comprise activated carbon filter tailored to match the capacity of the water flow in the system.
Ion exchangers – water softening
Water can be properly filtrated using the very efficient ion exchangers. These water filters are particularly attractive in food industries. Ion exchangers are successfully decreasing water hardness, removing nitrates and other overbalanced chemical elements. Ion exchangers function selectively so we can separate only those substances that we need.
Purpose of water softeners is to remove the so called total hardness from the water –magnesium and calcium salts forming sediment.
These salts are constantly creating the carbonate scaling problem in the water supply network as well as on the complementary sanitary resources. Water hardness is regularly a problem in technological processes, particularly in the food industries, as well as other industrial areas where the water must follow exact quality standards. Softened water is exceptionally suitable for steam boilers and boilers in circular systems.
The basic principle: Filter facility includes an ion exchanger calibrated to reduce above mentioned elements. After the processing a certain amount of raw water ion exchanger becomes saturated and requires regeneration. Regeneration is accomplished with Na Cl (ordinary kitchen salt). Filter facility must be stopped while regeneration is performed. The facility can continue operating again after regeneration is complete.
Softeners with two tanks Softeners carry out the job of removing the calcium and magnesium salts which are creating scaling on all surfaces that come in touch with the untreated water.
Carbonate scaling has negative effects on those contact surfaces. These units are constructed to allow continuous raw water treatment. One-tank units have to regularly stop processing water in order to regenerate the filling. Stopping water processing in turn cuts off water supply to other technological processes.
For that reason, the units are extended with another tank and special automated control valve that regulates the unit operation in the following way:
One tank treats raw water while the other is regenerated; when the filling in the first tank becomes saturated, the control valve automatically blocks the first tank and begins exploitation of the second tank, while first one begins the cycle of regeneration.
Regeneration process alternates to provide continuous water flow without any standstills.
These units can be tailored to any industry.
DEFERRISATION
Defferization process takes away excess iron from the water. Iron is frequently found in the water. It affects water color (giving it a reddish rust tone) and microorganisms are efficiently using it in their metabolism producing brownish sludge in the water supply and sanitary systems
This filling is adapted to remove manganese which means it has two functions. It removes both iron (Fe) and manganese (Mn). Water with high concentration of these elements is not so translucent and has the yellowish tone. Almost all of the Vojvodina region has higher concentration of iron in the water and manganese concentration is almost above the permitted level. These filters can remove hydrogen sulfate H2S and sometimes arsenic.
Water sterilization
Water, just like air is inhabited by a variety of microorganisms, mostly not desired in the consumable water, especially pathogenic microorganisms that may endanger human health. Sterilization can be performed in several ways but the most reliable and cheapest way is the sterilization by UV rays of certain wave length. UV rays instantly eliminate all microorganisms and as a result make the water sterile.
Sterilization is performed by the apparatuses called water UV sterilizators which are slowly but surely taking the momentum over other disinfecting methods like chemical dosages (chlorine). Dosing chemicals into water changes characteristics of the treated water. Treating humim rich water (water rich with living matter) with chlorine results in formation of harmful compounds which according to the latest research reports can be detrimental to human health if the water is used as consumable water. UV rays aren’t causing any chemical changes. This substantial advantage led to expansion of this technology. UV 254nm rays have devastating effect on the living organisms’ cells breaking cell chain instantly. Passing through the UV apparatus bacteria, viruses and other living organisms are eliminated in an eye blink.
Our UV lamps boast maximum intensity on wave length of 254nm, working life of 8000 to 10000 hours. Our equipment has capacity from 400 liters per hour to huge city water supply systems.
Sterilization of air above the water surface in open containers and containers under pressure is of interest in places where stored water comes in contact with the air. Air is always abundant with microbes of various species and sizes that are traveling around with dust particles. If the water containers are open or in contact with air – then an unavoidable contact of microorganisms with water leads to water contamination. Every container that’s not pressurized is plagued by this.
Our systems provide sterile air space above the water which prevents water contamination. There are two kinds of UV systems intended for this use.
1) UV-C lamp sterilization which provides sterile environment using ozone and UV rays 2) Sterilization using only the UV-C lamps with UV rays of different wave length
In last few years arsenic found in water in several Eastern European cities became an important issue. In Serbia and Montenegro arsenic captures news headlines and public attention too. Arsenic in the water might have the valency of 3 or valency of 5. Our filters are selectively removing arsenic of any valence and in quantities under 10 micrograms which is acceptable for humans. There’s a lot of misinformation and fraud present on a market in cases when vendors offer small filters that are supposed to filter arsenic. Arsenic can be removed using only the specialized equipment and buyers have every right to be unsatisfied with the effects of those small filters.
Our approach is to determine the most effective way of arsenic filtration on the basis of chemical analysis. Our filters remove harmful elements including Arsenic but healthy mineral salts remain.
Mechanical filters
In the water or in the water supply network we often find sand of various granulometric composition and other impurities (rust) which are mostly present due to network age and exploitation directly from the actual water source. Mechanical filters are put in place to remove impurities that spoil the water quality. These filters are simple to use and easy to maintain and replace.
Their function is to remove the mechanical impurities like sand, various particles of organic matter, corrosion leftovers, tiny specks etc. These filters are very practical because they can be counter rinsed out – we can clean the filter cartridge that captures impurities without having to disassembe the filter body. Cartridges performing the filtration have the density of 100 to 0,2 microns. Very often mechanical filters are used as a pre-filters to other filter units.
