AS REVERSE OSMOSIS (RO) plant proliferated over the year, so did the challenges in operation and maintenance of RO membranes used to process waters of hugely variable qualities. Complex fouling mechanisms need to be controlled, and failing that, adequate cleaning methods developed so that plant downtimes minimized and useful life of membranes preserved. Chemical treatments need to be conducted in such a way as to be compatible with specific sensitivities of various types of semi — permeable membranes.
Focus on customer needs and partnership with design and consulting engineers, system manufactures and plant operating personnels, brought about outstanding results. It is also widely recognized that the sensitive kinetic fouling conditions in RO system are sufficiently different from the steady state conditions in other water treatment systems such as cooling towers and boilers that RO chemistry is a speciality by itself, diagnostic skills, chemical selections and applications know how have become both a science and an art, and as such, the rate of growth of the RO chemistry field is restrained, and the practitioners that much more valuable.
Experience has shown that turn — key RO plant’s chemical, process and maintenance adjustments do not exist. The equipment is built to process water if varying quality, and should be treated as a part of a chemical process. Even little changes in the quality of feed water and pretreatment chemicals used can have noticeable impacts on membrane performance.
Coagulant
Complete range of coagulants to improve the efficiency of removal of colloidal particles for removal through multimedia filter or UF Membranes
Antiscalents: (PTP100)
PTP100 is a highly effective antiscalant, specially formulated for feed waters with highest levels of metal oxides, silica and scale-forming minerals. It is effective over a wide range of concentrations, and does not flocculate dissolved polymers such as residual coagulants, iron or aluminum rich silica. Use of this product is recommended for reducing the operating and capital costs of Reverse Osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) systems. A special utility is in its application as a substitute for pretreatment with ion exchange beds.
Antifoulants (Protec-RO-C)
Is a highly effective Antifoulant, specially formulated for feed waters with highest potential for fouling by colloidal particles and organic matter. It is effective over a wide range of concentrations. Use of this product is highly recommended for reducing the operating and capital costs of Reverse Osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) systems. A special utility is in its application as an antideposition agent for silt and colloidal organic matter in natural sea and brackish surface waters, Protective and flux — enhancing activity reduces the rate of fouling, and enhances the ease of subsequent cleaning. These properties are useful in product concentrations and water reclamation applications.
Sanitizers and Preservatives:
BioCare RO-20 is a non oxidizing biocide to control biological fouling in Reverse Osmosis (RO) systems. It will immediately function upon introduction into the feed water; the rate of this activity is not affected by pH, and antimicrobial control is rapidly achieved. Due to its extremely rapid kill, proliferating microbes and their biofilms formation on the RO membrane and in the feed channel spacers are either eliminated or significantly reduced. When added to an RO system, it is easily rejected by the thin-film composite membrane layer and, at use dilution, shows excellent compatibility with all materials of construction of the RO membrane module
