3 Antimicrobiologic al Pretre atment for M embranes BioGuard A C S antimicrobiological pretreatment reduces membrane cleaning requirements by effectively controlling membrane fouling from microbiological growth BioGuard ACS reduces membrane cleaning requirements by controlling cell metabolism and adhesion to the membrane surface and flow channels. Unlike conventional methods of biological control, BioGuard ACS does not rupture cells. Therefore, TOC levels do not increase, the RO membrane surface does not become fouled by cell remnants and other microorganisms are not fed by cell fragments. By controlling cell metabolism, BioGuard ACS inhibits the production of cell waste products which form the biofouling matrix. By controlling both cell adhesion and metabolism, this non-oxidizing method of controlling microbiological organisms reduces membrane cleaning requirements and improves system performance. Ideal for controlling microbiological growth on membranes Available in powder or liquid super-concentrate Complies with ANSI/NSF Standard 60 requirements for potable water Aerobic Biological Growth Anaerobic Biological Growth Iron Depositing Bacteria Slime Forming Bacteria Sulfate Reducing Bacteria Compatible with all membrane types BioGuard ACS is also available as a powder which reduces shipping and handling by 96% and shipping volume by 95%. It is also available in a liquid superconcentrate (BioGuard ACS SC ) which provides the convenience of a liquid yet reduces shipping/handling by 90%. BioGuard ACS and BioGuard ACS SC may also be introduced from the same injection point as any PWT antiscalant/dispersant, facilitating dual product application. BioGuard ACS and ACS SC are the first antimicrobiological pretreatments that comply with ANSI/NSF Standard 60 requirements for potable water systems. Stable in the presence of metals May be injected with any PWT antiscalant/ dispersant from a single blended tank BioGuard ACS is compatible with all membrane types and system components ensuring product reliability online. It is also inherently stable in the presence of multivalent ions such as iron. BioGuard ACS may be applied as an on-line continuous feed or as a periodic hot-shot treatment.

5 O rg a nic C ontroller for M e m bra n e s OrganoGuard organic pretreatment controls hydrocarbons, cellulosic material, lignins, dyes, waxes, paraffins, oils, and other organics in fluid treatment processes OrganoGuard is a process aid designed to control organic fouling of membrane separation systems. Utilized at ppm levels, OrganoGuard controls organics in process streams containing refined oils, vegetable byproducts from food processes, dyes and chemicals from textile processing, cellulosic and chemical byproducts from paper mills and other organics found in treatment processes. A preventive maintenance program including OrganoGuard reduces cleaning requirements while maintaining optimum operating efficiency of the processing system. Reduces organic fouling of water treatment & separation systems Reduces system cleaning requirements improving system operation efficiency Compatible with most other pretreatment processes and chemicals Hydrocarbons C ellulosic Material Lignins Dyes Waxes Paraffins Paper Pulp Byproducts Heavy Crude Oils Light Machine Oils OrganoGuard utilizes a unique proprietary polymeric system to stabilize and separate hydrophobic and weakly hydrophilic organics by use of a unique surface active chemical physics process. Hydrophobic organics are separated and stabilized reducing maintenance requirements of the membranes. Weakly hydrophilic organics are also stabilized as water soluble molecular complexes which minimizes fouling of membranes. OrganoGuard is stable in the presence of both cationic and anionic polymers so it may be safely used in conjunction with most other pretreatments. OrganoGuard complies with ANSI/NSF Standard 60 requirements and may be used on potable water systems.

6 Powder Membrane Preservative Preservol membrane preservative allows membranes to be safely stored Preservol powder membrane preservative allows membranes to be stored for short and extended periods without loss of performance. As a powder, Preservol is more convenient to store, easier to handle and may be transported more economically. This product is reliable at extreme temperatures and has an extended shelf-life, maintaining product stability long-term. Preservol is safe for use on polyamide thin-film composite membranes, cellulose acetate membranes, nanofiltration and ultrafiltration membranes. Pro d u c t A p plic a tion Long Term Storage Thoroughly clean membranes with Lavasol or OptiClean membrane cleaners. Short Term Storage Mix 1 pound of Preservol to 6 gallons of good quality water such a RO permeate or better. Polyamide Thin Film Recirculate solution for at least 15 minutes. A recirculation pressure of less than 60 psi is recommended. Cellulose Acetate After recirculation, shut-down the system. Do not allow the Preservol solution to drain from the membranes. The membranes may then be stored in the system vessels or they may be removed and stored in separate containers. Hollow Fiber Nanofiltration Ultrafiltration To use membranes after storage, first rinse them for 30 minutes using good quality water such as DI or RO permeate.
