The reverse osmosis is a process of "filtration by means of semipermeable membranes". This process allows starting from salt water to produce pure water, in fact, by exerting a pressure greater than the osmotic cancels the natural tendency that have two solutions at different concentration, in the presence of semi-permeable membrane, the pure water to migrate towards that salt.

The water demineralizing Plants eliminate all the salts contained in it. Water obtained by this process, meets the needs of hospitals, chemical processing, power plants etc. They are essentially constituted by a heat exchanger containing the cationic resins and a heat exchanger containing the anionic resins. The heat exchangers can be made in: - fiberglass - Ebonized steel - Acid-resistant steel

Recently a new deionization technology, the continuous electro-deionization has been developed, which is a combination of electro-dialysis and ion exchange. It is obtained by a process, which deionized water while the resins are continuously regenerated by means of the electric current inside the unit. This electrochemical regeneration replaces the traditional chemical regeneration of ion exchange systems. The electro-deionization module must be supplied with pre-treated water with reverse osmosis: By combining these two techniques is obtained ultrapure water (0.1-0.2 mS / cm), starting from the drinking water.

The fdt dosing stations are made entirely at our factory with the best materials and according to the latest manufacturing techniques. They find applications in all the complementary treatment of water by injection of appropriate chemicals. The fdt Ltd metering stations thanks to the modern design of the injection units and a modern and efficient control systems allows a fully automatic operation. Function and are covered by fdt Ltd warranty, design risk by leading insurance company.

The chlorine dioxide is an interesting alternative to chlorine due to the different composition. Chlorine dioxide produces no organic chlorine compounds in contact with the most frequently contaminants present in the water. The compounds resulting from the reaction between chlorine dioxide and organic compounds in the water are therefore more negligible in terms of quantity, perceptive and toxic. This makes chlorine dioxide agent ideal disinfectant for drinking water treatment.

The construction site of machinery and technological systems is critical for companies that want to compete globally and want to offer their plants abroad in the global market. Feasibility study and indoor / outdoor layout Both the internal configuration of the container and external devices are studied from time to time according to the specific needs of the customer.

The water to be filtered enters via the inlet connector tangentially to the cylindrical body, it falls on the acceleration cone and increases more and more speed - The centrifugal force that is created by separating 'water the suspended solids with higher specific weight . A separation occurred the filtered water is conveyed into the outlet manifolds, while the impurities descend into the collecting tank where, special deflectors shall reset the speed preventing the ascent. The contaminant is removed drenandolo continuously or in time through the discharge valve. Uses: • For the protection of installations in which circulates industrial or domestic water. • For the protection of closed or open circuits of hot and cold water, cooling systems (in particular of the spray nozzles and the evaporating bodies). • For protection of the gland, the labyrinth seals and clutch rings Carbon mechanical seals for pumps and turbines.

The number of FDT chemicals plant comes from the experience gained and as a complementary service to the supply and management of systems.

The compressor of the gas turbine is the component with the greatest impact on the performance of the turbine itself. It is therefore necessary that it is always perfectly efficient. The blading of the compressor, in addition, is subject to the surface deposits of impurities that accumulate during operation of the machine, it consists of the contaminants from the external environment (sea air, dust, fertilizers, etc.) And in part by the machine itself (vapors of oil from the compressor bearing). This creates the need to remove the deposits through the washing of the compressor, so as to restore the normal efficiency.

The reverse osmosis is a process of "filtration by means of semipermeable membranes". This process allows starting from salt water to produce pure water, in fact, by exerting a pressure greater than the osmotic cancels the natural tendency that have two solutions at different concentration, in the presence of semi-permeable membrane, the pure water to migrate towards that salt. Its main application is the filtration of saline waters, whether of aqueduct or well water, for the production of high quality demineralized water. The reverse osmosis is also applied in the treatment of wastewater for the partial recycling of the same. The reverse osmosis systems are extremely versatile, with modular flow depending on the capacity required. Through "two-stage process", it is also possible to produce ultrapure water. The main application of reverse osmosis is the deionization OF PRIMARY WATERS.
