    The reverse osmosis treatment technology is the most update one, since being utilized for the production of drinkable water from both sea water and brackish water.
    The R.O. technology utilizes special membranes, which -through a high pressure process- allow to separate salts from water, so producing drinkable water, in full compliance with the World Health Organization standards.

    Sea Water Desalination
    The limiting factor in the Sea water reverse osmosis desalination plants is of a physical nature
    i.e. higher pressure is applied in order to overcome the osmotic pressure caused by high TDS.     Products
    In fact, due to the continuous improvement of membranes quality and relevant performance, the R.O. plants and the utilization of energy recovery turbines are now requiring less and less energy and chemicals consumption.
    • Open Intake (Surface Water)
      The intake of surface water, should be located away from the shore and some meters below the water surface, also high level of pretreatment is required to minimize the fouling potential of the feed water.
    • Well Intake
      In general well water is consistent feed source which has a low Silt Density Index (SDI) and low bacteria count therefore simple pretreatment scheme is required.

    Brackish Water Desalination
    The limiting factor in the Brackish water reverse osmosis desalination plants is of a chemical nature,     Productstherefore proper selection of the chemical used as scale inhibitor is of great importance to avoid scale formation
    It should also be taken in consideration that Brackish water reverse osmosis desalination allows saving up to 50 times of the operation costs compared to the traditional ion-exchange.

    Scope Of Treatment:
    • Reduction of dissolved salts in water either for human use or for industry.
    • Reduction of nitrates concentration in drinkable water.
    • Removal of bacteria in water for pharmaceutical preparations
    Applications:
    • Sea water desalination for civil use.
    • Partial demineralizing of feed water for low pressure boilers.
    • Partial demineralizing to feed ion exchange plants.Products

  • Potabilization
    Water supply is nowadays requiring a continuous development in plants installation in most of the countries, due to the increasing pollution of both water tables and surface water as well.
    The specific plant engineering will be chosen time by time according to the type of polluting agents to remove.

    Disinfection
    • Chlorination
      Chlorine is the most commonly throughout the world. The reason is that chlorine satisfies most of the requirements such as availability, solubility, stability, toxicity to microorganisms,..etc.
      The principal chlorine compounds used are chlorine, sodium hypochlorite, calcium hypochlorite and chlorine dioxide.Many of the safety concerns related to the transport, storage and feeding are eliminated by the use of either sodium or calcium hypochlorite
    • Ultra violet
      Ultraviolet irradiation is known to have a germicidal effect. Its application has come into use especially for small-scale plants. No chemicals are added, and the equipment needs little attention other than periodic cleanings or replacement of the mercury vapor lamps.
      Treatment with ultraviolet light is a popular form of disinfection due to ease of use. Water is exposed at a controlled rate to ultraviolet light waves. The light deactivates DNA leading to bacterial reduction. With proper design and maintenance, UV systems are simple and reliable for a high reduction in bacteria (99+ %).
    • Ozonation
      Ozone is useful for color removal, taste and odor removal, disinfection, iron and manganese removal, phenol oxidation, and cyanide oxidation.
      The high oxidation capacity of ozone places it in the first level position for removal of polluting agents generated by industrial processes and for disinfecting water for human consumption.

    Scope Of Treatment:
    • Elimination of bacteria and other undesired matters.
    • Water treatment for human use.
    Applications
    • Production water for human use.
    • Production of water meant for food and drink industry.
    • Pre and Post treatment of brackish water and seawater desalination plants.

    pH adjustment:
    Municipal waters may be pH-adjusted to approximately 7.5 to 8.0 to prevent corrosion of water pipes and fixtures, particularly to prevent dissolution of lead into a potable water supply. In the case of excessive alkalinity, the pH may be reduced by the addition of acid. The alkalinity will convert to CO2.

    Scope Of Treatment
    • Water treatment for human use.
    Applications:
    • Production water for human use.
    • Pre and Post treatment of brackish water and seawater desalination plants.

  • Waste Water TreatmentProducts

    Domestic Waste Water Treatment
    Waste water treatment for residential areas, touristic villages and communities in general, by means of the total oxidation activated sludge biological process.
    Such process consists of primary treatment (screening, oil & grease removal, equalization, etc.), secondary treatment during which the excess effluent organic contents are oxidized by an activated sludge process (Biological oxidation, sedimentation), tertiary treatment is often included in order to recover the treated water for irrigation, agriculture, etc.
    The treated water specifications are in full compliance with the limits specified by the Environmental Protection Law.
    The excess sludge is completely mineralized either in the oxidation tank yet or in a separated tank (aerobic digestion).
    Particular care is given to the ammonia oxidation (nitrification), denitrification, and de-phosphatizing.Products
    Applications:
    • Residential areas
    • Tourist villages
    • Communities

    Industrial Waste Water Treatment
    It has to be considered that each and every industrial effluent treatment plant is to be designed case by case, since its required performance are strictly depending upon the specific pollutants involved.
    Concerning industrial waste with biodegradable pollutants, treatment plants are suitably designed applying the integrated cycle activated sludge biologic process.
    The clarified water is then submitted to chemical - physical treatments (clarification - flocculation, filtration, disinfecting, etc.) and also to membrane processes (ultrafiltration, reverse osmosis), in order to attain such water characteristic as to allow recovering it in industrial use.
    Whenever the effluent is not biodegradable, its treatment is carried out by adopting either a chemical-physical or a membrane separation process (ultrafiltration, reverse osmosis).
    Such treatment can be integrated with specific pre-treatments (ozone, U.V. etc.) in order to achieve, wherever necessary, an effluent quality level such to guarantee both its suitability for discharging and its possible re-use in industrial activities.     Applications:
    • Textile industry
    • Food industry
    • Oil industry
    • Chemical industry
    • Others

    Sludge Dewatering Units
    Dewatering is a physical process used to reduce the moisture content of sludge and biosolids for one or more of the following reasons:

    • Reducing the costs for trucking sludge.
    • Handling of sludge and biosolids are generally easier.
    • Dewatering is required normally prior to the incineration of the sludge.
    • Dewatering is required before composting.

    Several techniques are used in dewatering devices for removing moisture. Some of these techniques rely on natural evaporation and percolation to dewater the solids. In mechanical dewatering techniques, mechanically assisted physical means are used to dewater the sludge more quickly.
    Alternative methods for dewatering various types of sludge and biosolids include:

    • Solid-bowl centrifuge.
    • Belt-filter press
    • Recessed-plate filter press.
    • Sludge drying beds.
    • Sludge lagoons.
