Blocking of the membrane due to contamination by any kind of particulate material is known as fouling. It can be caused by suspended colloidal particles or indeed, be a biological contamination on the surface of the membrane (bio-fouling).Reverse osmosis has become a prime source of drinking water and make-up water for industrialprocesses. Loss of performance of reverse osmosis membranes is mainly due to fouling, scaleforming salts and biological contamination, or the insufcient pretreatment of make-up water.  Antiscalants Complete and Innovative Treatmentfor Reverse Osmosis and other Membrane Systems  Any kind of fouling is not desired, as it will imply losing ltration performance and water quality, increase of operational costs and plant breakdown.Most of the developments done nowadays in Desalination Engineering are dedicated to Operation Cost Reduction: development of Brine Energy Recovery Systems and Energy effective membrane and plant designs. It has been demonstrated that the presence of fouling and deposits on the membranes has a strong negative impact on energy consumption. The application and design of a correct water treatment program not only will reduce the plant operational costs, but also will improve the performance of the plant allowing high recovery rates, granting smooth operation, reducing the number of cleaning steps and improving efciency. Type of deposits or contaminationType of deposits or contamination InorganicBlends of inorganic and organic acidsOrganic or colloidal foulingOptimized combinations of complexants, alkali, caustic soda, potassium hydroxide, anionic and non-ionic detergents, phosphatesBiologicalAlkaline and/or enzymatic cleaners What is Scaling? During the reverse osmosis (RO) process, a salt solution ows along a membrane and is concentrated to a certain level. When the concentrations of the dissolved salts exceed their solubility levels, the salts may precipitate. A crystalline layer is formed which is known as scaling. With decades of experience in Water Treatment, ICL Water Solutions combines innovative technologies and services. Thanks to our intensive research and development we can offer an extensive range of products. Specically for Membrane processes we developed the product line: Osmotech ® : Osmotech ®  technologies prevent membrane fouling and scaling as well as clean the membranes from all contaminants that might be encountered.Osmotech ®  helps you optimizing the efciency of your membrane processes, achieving the greatest economy and long-term operational reliability. Osmotech ®  prevents membrane fouling, reduces the frequency of cleaning and thus increases membrane performance and lifetime. A full range of antiscalants is available with specic programs against precipitation of various salts, e.g. based on: The essential properties of Osmotech ®  products are scale inhibition and hardness stabilization. In the sub-stoichiometric range, they show the so-called Threshold effect. Beyond the stabilisation limit a non-adherent amorphous crystal is obtained so that they can be easily rejected from the membrane system by means of the brine ow and its “sweeping effect”. Furthermore, the dispersants delay the sedimentation of mineral sludge in RO systems. They transfer sludge deposits into the aqueous phase and remove them from the system in the concentrate ow.   » Calcium and magnesium hardness deposits  » Calcium phosphate and calcium uoride   » Calcium, barium and strontium sulphate  » Iron oxide  » Silica and manganese Cleaners Discover the performance of Osmotech ®  formulated cleaners for your membrane systems.  As a very important step in maintenance programs, cleaning allows restoration of peak membrane performance. Our full range of acid, alkali or enzyme based cleaners were tested in our membrane-dedicated laboratory for efciency and compatibility with main types of membranes. Applied according to customized procedures, they will remove all possible contaminants that might be encountered. Pretreatment and Auxiliaries Biocides & Disinfectants  Additional to the classical treatment with oxidizing biocides, ICL Water Solutions has developed a full range of environmental friendly non-oxidizing biocides which allow a direct contact with the membrane for a better disinfection and control of bacteria, fungi, and algae growth in membrane systems. Chlorine and Oxidizing Biocide Removers Products to protect the membrane from the attackof aggressive biocides Flocculants & Coagulants Products to achieve the best quality of make-up water for your membrane systems  Attention: Use biocides safely.
