    Reverse Osmosis Water Testing

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached. Reverse Osmosis (RO) is a membrane process of purification which removes most of the the total dissolved solids (TDS) in water by reversing the natural process of osmosis. Pressure is applied to a TDS-concentrated solution against a semi-permeable membrane, causing pure water to diffuse through the membrane. RO has become an important process for a wide variety of applications including: medical, laboratory, desalination, industrial wastewater, Deionized (Dl) pretreatment, and drinking water.

  • Reverse Osmosis - Pretreatment and Clarification - Wils ElectroWaveTM Conditioning

    Wilsa ElectorWaveTM Conditioning can be used to pretreat water for reverse osmosis. The Wilsa Effect breaks emulsions, enhances separation to remove hydrocarbons and clarify solids before entering RO treatment. The effect also substantially lowers the viscosity of the water which allows it to pass through membranes with less effort.

  • Using evaporation to dewater Reverse Osmosis reject waste streams

    Reverse Osmosis (RO) technology has been used for years in various industries to separate dissolved solids from water by forcing the water through a semi-permeable membrane. RO is also commonly used to purify drinking water and desalinate seawater to yield potable water. The water and other molecules with lower molecular weight (specific weight of molecules allowed to pass through is dependent on the selected membrane) pass through the micropores in the membrane, yielding a purified water stream called the permeate. Larger molecules are retained by the membrane as well as a portion of the water that does not pass through the membrane. This concentrated stream is called the concentrate or RO reject.

    CleanOxide usage in reverse osmosis water treatment

    Biological fouling of reverse osmosis is a common problem leading to reduced efficiency and reduced membrane life. CleanOxide Liquid 75 is pure Chlorine dioxide which is a highly effective biocide ideal for use in reverse osmosis systems. CleanOxide Chlorine Dioxide has all the important regulatory approvals in Australia and overseas to be used in water treatment and food processing. Many strategies have been developed in an effort to control biofouling of Reverse Osmosis membranes including the use of sodium hypochlorite, non-oxidising biocides, heat and pH swings.

  • Industrial and commercial water filtration for reverse osmosis plants

    Reverse Osmosis or RO is a system used to produce an ultra-high quality of water with use of membrane. Reverse Osmosis plants are required in many production processes.  Damage to these high quality membranes can easily be caused if no pre-filtration is in place to protect the system from high loading, this can result in extremely high costs of repairs, ranging from tens of thousands to millions, not to mention the loss of production to a company if as a result of plant failure production has to be stopped until the system is repaired.

    Chemical Water Treatment for membrane treatments

    Membrane units, in our days are widely used in the water pre-treatment preparation and are becoming one of the most important technologies in the production of high pure water. Nevertheless they often face problems with scaling and fouling and are therefore limited by frequent maintenance, downtime and high costs. Our treatment programs are specifically designed for membrane units like reverse osmosis, ultra- and nanofiltration and enable to remove or preventive control scaling and fouling. Our main target is to run these plants under environmentally friendly and beneficial economic conditions. Special attention is given to an efficient utilization of energy as well as saving precious water. Kurita develops an efficient and effective treatment concept achieving an optimal economic operation and a maximum operational reliability of a plant.

  • Membrane filtration systems for reduction of BOD/COD

    Reverse Osmosis Polishers can concentrate BOD/COD from evaporator condensate and RO permeate streams to reduce waste water. Polished water can also be re-used in plant for boiler water make-up and CIP systems. In Dairy Industry applications, `polishing` of these process water streams aids in the production of Class I water for re-use from dairy products as defined and regulated under Food & Drug Administration rules. Water produced with this technique is also very soft, generally resulting in lower cleaning chemical consumption.
