Water treatment
The installations are designed based on customized technologies depending on the type of waste water and the effluent quality requirements. Depending on the adopted technology, we use equalization/homogenization, pH correction, flotation, flocculation, coagulation, sedimentation, decantation, filtration, ultrafiltration, sludge dehydration modules.
The installations are equipped with the most modern dosing and monitoring systems and programmable controllers with local and/or remote interfaces.
EUROTROL and SITA filtration sistems serve both industrial and residential applications.
Mechanical water filters use washable or disposable filter cartridges, including drinking water as well as other cold or hot liquids.
These cartridges are recommended for the filtration of drinking water, soft drinks and beverages, boiler water, softeners and to protect refrigerators and air conditioning devices.
Automatic quartz and multimedia filters retain suspended solids that give water turbidity such as sand, mud, rust, etc. The container of these filters is usualy made of polyethylene reinforced with fiberglass or (at high capacities) of corrosion protected carbon steel. Inside lining consists of a food grade epoxy resin layer, and outside of a polyurethane resin layer. The filters are equipped with PENTAIR-AUTOTROL electronic control systems using digital programmers and hydraulic valve systems operated either by water pressure or an outside air compressor.

Automatic activated carbon filters from EUROTROL have a filtering bed made of a layer of activated carbon placed over a layer of selected sand. These filters are commonly used to remove organic substances, residual chlorine from the water and to improve the taste, color and smell of the water.
The container of these filters is usualy made of polyethylene reinforced with fiberglass or (at high capacities) of corrosion protected carbon steel. Inside lining consists of a food grade epoxy resin layer, and outside of a polyurethane resin layer. The filters are equipped with PENTAIR-AUTOTROL electronic control systems using digital programmers and hydraulic valve systems operated either by water pressure or an outside air compressor.
These systems used either individually or in series are intended to eliminate or reduce the concentration of some pollutants: calcium and magnesium ions, iron, manganese, nitrate, ammonium, arsenic.
The pressure vessels are made of containers of polyethylene reinforced with fiberglass fiber, PENTAIR-AUTOTROL digital electronic programmer (for setting the start of regeneration process, frequency of regeneration and the duration of regeneration phases), a system of hydraulically operated automatic valves and a vessel made of polythene for the regenerating solution (brine).
Simplex automatic systems have a single column. During the regeneration the system delivers untreated water. Duplex automatic systems or multiple parallel column systems allow the continuous supply of treated water by means of secvential regeneration of the ion-exchange resin in the different columns.
Ultrafiltration and reverse osmosis are among the most effective methods in water treatment regarding hazardous contaminants: arsenic, asbestos, herbicides, pesticides, fluoride, lead, mercury, nitrates, nitrites, radium, etc.
Reverse osmosis systems retain dissolved chemicals as well as biological agents in water, the obtained water having a high degree of purity.
Reverse osmosis systems are suitable for removing bacteria, viruses, fungus and other biological components of the water which are harmful to health such as Giardia and Cryptosporidium.
