WAT E R FI LT RAT IO N Filtration is the most common and widely used method for extracting suspended particles, mechanical impurities and excess ions from the feed water. Wide range of filtration materials guarantees selective removal of contaminants and high quality of water for different purposes. Key benefits of filtration process are reliability, stability and long term operation. New technologies and modern water treatment solutions expand application fields for filtration materials providing simple and cost effective operations.

MECHANICAL FILTRATION Mechanical filtration is used for removal of mechanical impurities from the feed water, but it can also provide full liquid – solid separation by applying filter cartridges of difrent porosity. 1.Backwash filters (manual and automatic) with connections from DN20 - DN125 and various pore sizes 2.Sediment filters Filter cartridges (plastic simplex/duplex and stainless steel for multiple cartridges). Filter cartridges (PP, fiber, washable, carbon block, dual-layer from 100 µm up to 0.2 µm for wide range of applications). SAND FILTRATION Sand filters are used for basic filtration of mechanical impurities and dispersed substances from the feed water. They are filled with multiple layers of high quality quartz sand and gravel of different granulation. In order to achieve better and faster filtration, sand filters are often part of water purification systems containing suitable filter material. Sand filters retain solid particles at their surface and throughout the bed depth. Dispersed particles are retained in the upper sand layer that has the finest granulation. IRON, MANGANESE AND H2S REMOVAL SYSTEMS One of the most important steps in water treatment is iron, manganese and H2S removal. These impurities can form insoluble hydroxides that can cause some vital parts of water treatment systems to collapse. As far as drinking water is concerned the upper limits for iron and manganese contents are 0.3 mg/l and 0.05 mg/l, respectively. Filter systems operate on the basis of oxidizing Fe(II) and Mn(II) to insoluble forms that are kept trapped throughout the bed depth. Depending on feed water quality and specific application different filter medias can be used. We can apply filter medias with superior capacity that can be regenerated as well as those that require only periodical backwash. DECHLORINATION – ACTIVATED CARBON FILTRATION Activated carbon filters are based on adsorption principle and can be applied at every stage of water treatment. Granulated activated carbon is an adsorbent with high capacity for removal of total organic impurities from feed water (75-95%). Water with high organics content has bad taste and odor, and chlorination process makes this even worse, because chlorine reacts with phenols from feed water and forms chlorophenoles. Activated carbon adsorbs residual chlorine and smaller molecular weight organics from water and provides odorless and tasteless water as the final result. Another typical application for these type of filters is prefiltration as prevention for ion-exchange resins and RO membranes. MULTIMEDIA FILTERS ARSENIC AND AMMONIA REMOVAL Multimedia filters are designed according to specific demands and row water quality. Different medias are used for selective removal of specific contaminants and in this manner you can get fast and highly effective water treatment with one system that doesn’t require a lot of space. 10_11

CWG_SOFT / VAK (compact softeners) Due to it’s unique compact design VAK type of water softener is widely used in households, apartments, restaurants, dry cleaning and car-wash. This softener is easy to fit to the interior and it doesn’t require a lot of space. It’s efficiency will be obvious right away because calcium carbonate deposits, scale and white stains will become history. One of it’s features is automatic control of regeneration process, that can be set to start at desired time of the day. CWG_SOFT / VAS (simplex system) VAS - water softener is commonly installed for the purposes of producing required amount of treated water. It is usually designed according to soft water consumption per hour, which ensures sufficient capacity. One of it’s features is automatic control of regeneration process, that can be set to start at desired time of the day. This softener is widely used in cooling and heating systems, hotels, apartments, etc. CWG_SOFT/VAD (duplex system) VAD - water softener continuously provides treated water 24/7. Efficiency and reliability of this product guarantees that you will have no problem with water hardness at all. This type of water softener is widely used for industrial applications and for the purposes of large and continuous consumption of soft water (0-24h), for large cooling and heating systems, automatic car wash, industrial production (food, wood, glass, metals), hotels, apartments, camps, etc. AMBERSOFT This specific type of water softener is an up-flow system with ion-exchange resin filled to the very top of the tank. Key feature of this unit is low maintenance cost, due to lower consumption of granulated salt (NaCl) and treated water used for regeneration. This unit is automatically operated by PLC programmed for volumetric control. Regeneration will start when assigned capacity is exhausted. 12_13

ME MBRAN E T E C HN O LO GIES The best quality of treated water for the industrial applications is achieved by membrane separation systems. Semi-permeable membranes extract suspended particles, organic molecules, bacteria, viruses and most of the ions from the feed water. Reverse osmosis Nanofiltration Ultrafiltration Electrodeionization Desalination These technologies can be applied anywhere: for the purpose of process water production in industrial applications as wellas for drinking water treatment. Membrane separation technologies provide the highest quality water with max. efficiency and low energy consumption.

Reverse osmosis (RO) Reverse osmosis is membrane technology used for dissolved ions removal with the efficiency of 94-99%. It is used for desalination, process water and other applications that require demineralized water quality. This filtration method removes many types of large molecules and ions from the feed water by applying pressure to the water when it is on one side of a selective membrane. As a result, contaminants are retained on the pressurized side of the membrane as concentrate while pure water passes through to the other side and is known as permeate. Nanofiltration (NF) Nanofiltration is one of the technologies introduced in the last decade, but rising ever since. Nowadays, it is usually applied for drinking water treatment, for softening, decolorization, removal of micro particles. In industrial applications this technology is commonly used for removal of specific contaminants, for example colors. Separation process takes place on the membrane surface, as water passes through the membrane and therefore this technology is used for removal of organics, micro pollutants and multivalent ions. Membranes used for nanofiltration are designed to retain single valence ions. Ultrafiltration (UF) Ultrafiltration systems are used for removal of viruses and organics from the feed water . Membranes are designed to remove contaminants in the range 0.001 – 0.1 µm. Typical applications: Food industry (proteins, dairy and dairy products) Metallurgy (oil, water emulsion separation, color treatment) Textile industry Waster water recirculating systems Electrodeionization (EDI) EDI is the latest technique where electrodeionization is used for final water purification to reach conductivity <1 µS/cm. Initial module has 0.2-4.5 m3/h capacity, and by combination of modules EDI can reach specified flow rate. Desalination There are approximately 40 million milligrams of dissolved minerals per one cubic meter of see water . Total dissolved solids (TDS) in cationic forms: calcium, magnesium, sodium and potassium, but also in anionic forms: carbonates, bicarbonates, chlorides, sulphates and nitrates – resulting in high water conductivity, great corrosion potential and bad taste. According to drinking water standards, quality of this water is not acceptable. Therefore, in order to make see water useful and applicable for both industrial or municipal purposes it is necessary to treat it through desalination process. Water content: Sea water Brackish water Fresh water (35.000-45.000 ppm NaCl) (3.500-15.000 ppm NaCl) (500-2.000 ppm NaCl) 14_15
