BioGuard ACS™ antimicrobiologicalpretreatment reduces membranecleaning requirements by effectivelycontrolling membrane fouling frommicrobiological growthBioGuard ACS™ reduces membrane cleaningrequirements by controlling cell metabolism andadhesion to the membrane surface and flow channels.Unlike conventional methods of biological control,BioGuard ACS™ does not rupture cells. Therefore, TOClevels do not increase, the RO membrane surface doesnot become fouled by cell remnants and othermicroorganisms are not fed by cell fragments.

By controlling cell metabolism, BioGuard ACS™ inhibitsthe production of cell waste products which form thebiofouling matrix. By controlling both cell adhesion andmetabolism, this non-oxidizing method of controllingmicrobiological organisms reduces membrane cleaningrequirements and improves system performance.

BioGuard ACS™ is compatible with all membrane typesand system components ensuring product reliability on-line. It is also inherently stable in the presence ofmultivalent ions such as iron. BioGuard ACS™ may beapplied as an on-line continuous feed or as a periodichot-shot treatment.

BioGuard ACS™ is also available as a powder whichreduces shipping and handling by 96% and shippingvolume by 95%. It is also available in a liquid super-concentrate (BioGuard ACS SC™) which provides theconvenience of a liquid yet reduces shipping/handling by90%. BioGuard ACS™ and BioGuard ACS SC™ mayalso be introduced from the same injection point as anyPWT antiscalant/dispersant, facilitating dual productapplication.

BioGuard ACS™ and ACS SC™ are the first antimicro-biological pretreatments that comply with ANSI/NSFStandard 60 requirements for potable water systems.
