    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.

  • 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 of a crystal require numerous factors to coincide. CALSTAT RO-30 provides crystallisation interference at a molecular level :  Excellent results are achieved at low trace quantities of product. Calstat RO-30 dosed at trace levels of 4-10 kg per million litres  Corrosion on steel surfaces is reduced or eliminated  For drinking water production with RO (reverse osmosis) systems, membrane fouling is reduced.

  • 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.
