PWT - Biological Fouling Control

Biological Fouling Control

Bugs grow and proliferate, quickly. BioGuard ACS™, the industries’ best, biological by-product dispersant prevents biological proliferation by inhibiting slime adhesion to the membrane surface. Like most PWT products, BioGuard ACS is phosphate free, and available in standard dilution or in liquid super concentrate. When biological slimes foul your membrane(s), BioGuard Shock and BioGuard ISO will kill the bugs and get your system running smoothly again.

For compatible membranes and applications, see our product application chart.

BioGuard ACS™
By preventing adhesion of biological materials to the membrane surface and feed flow channels, BioGuard ACS optimizes system performance for the long haul. Available in standard strength dilutions and liquid super concentrate, our phosphate free formula disperses the bugs and pushes them in to the concentrate, not your membranes.

BioGuard Shock™
An industry standard biocide formulation with EPA registration for use in membrane systems, BioGuard Shock is fast acting, non-oxidizing and degrades quickly after use. Applied as a ‘shock treatment,’ this formulation is an economical method to removing bio-film from membrane systems and related plumbing.

BioGuard ISO™
Another industry standard biocide containing 1.4% strength isothiazoline, BioGuard ISO is typically applied by continuous injection, and is effective at low dose rates. This product is registered with the EPA for use in membrane systems, it readily biodegrades to non toxic by-products.
