    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...

  • Prefilters in microfiltration, ultrafiltration, nanofiltration and reverse osmosis processes

    The sizing and frequency of cartridge / bag replacement, in cartridge / bag filters used as pre-filters in fine filtration applications depends directly on the amount of suspended solids in the water.

    Wastewater evaporator Solutions for the reverse osmosis reject/concentrate

    It may seem paradoxical, but processes used to clean water actually also create wastewater. Reverse Osmosis creates clean water by forcing the water through a semipermeable membrane that filters out many moleclues. The problem is with the water that`s left, that does not pass through the membrane, which has an extremely high concentration of salts and minerals. This water is called RO reject or reverse osmosis concentrate. Reverse Osmosis reject can sometimes equal as much as half the volume of the original feed...

  • Chlorine Dioxide Water Treatment for Reverse Osmosis Membranes Industry

    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...

  • Water treatment solutions for the desalination

    Our Filters are Highly Resistant to Corrosivity. Reverse osmosis is one of the most widely applied desalination technologies. Previous to the process of separtion of water from salt and minerals, seawater or brackish wter requires the elimination of large size particles in order to assure a good performance of reverse osmosis membranes. Our sand filters facilitate the removal of these suspended solids to avoid membrane fouling. In addition, after reverse osmosis process, water has to be remineralized through...

    Custom skid-mounted water purification equipments for desalination industry

    RO desalination technology was initially developed in the late 1950s, and has now evolved into the leading desalination technology globally. There are many different processes used in RO desalination, and a variety of factors come into play when selecting the appropriate solution for each situation – the quality of the source water, the desired quantity and quality of the water produced, pretreatment, energy requirements and disposal of concentrate. At Advanced Equipment and Services we focus on desalination...

  • Liquid Rock - Prevening Scale Formation from Ground Water Hardness

    Groundwater is in contact with soil and rock minerals. Significant amounts of the minerals are dissolved in the groundwater. Elevated water hardness is the result of the water interaction and partial dissolution of carbonate minerals. Scale formation is a crystallisation process. Crystals are a highly organised arrangement of molecules. The determining circumstances for a successful crystallisation event include concentration, temperature, pressure and chemical environment. Suitable conditions for the formation...

  • 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...
