Pretreatment Products


Synder Filtration offers a wide range of pre-treatment options to help maintain membrane life and sustain performance. Ranging from cost-effective bag filters to large volume multimedia filters, Synder’s pretreatment products are engineered to reduce the amount of chemical constituents and particulate matter that can foul membranes. Contact us today to learn about the right pretreatment options for your application.




Chemical Dosing
Small peristaltic pumps constantly deliver low concentrations of antiscalant, antioxidant (for chlorine), pH balance (acid/caustic), or other pretreatment chemicals to ensure high performance of your membranes.

Cartridge Filters
Cartridge filters are a good “final catch” before the membrane. Filtration rates from 0.1micron to 100micron are available.

Water Softeners
Synder Filtration’s water softeners are designed to remove inorganic ion species from the feed solution via ion exchange resin loaded into a tank with a recharge control head and backflush capabilities.

Bag Filters
Bag filters are a cost effective method of reducing particulates in feed streams, resulting in an increase in membrane life and performance. Bag filters ranging from 5micron to 100micron are available, with the most common sizes being 25, 50, and 100micron. Oil absorbing and other options are also available.

Activated Carbon Filters
Granular Activated Carbon (GAC) is excellent for removing organic solvents in water, including chlorine.

Multi -Media Filters
Multi-Media filters are an optimal choice when dealing with large volumes of TSS & turbidity. Reverse Osmosis Cleaning Chemicals – Synder’s RO cleaning chemicals range from dosing chemicals used for CIP cleaning to acid and caustic cleaners. We understand the need to keep your RO system running at peak performance and have many cleaning chemicals available to meet that requirement.



Cleaning & Dosing Chemicals



Powerflux™Concentrate – Ultrafilter Cleaning Solution for Electrocoating
Power Flux Concentrate (PFC) cleaning solution was formulated specifically for removing paint solids from Synder’s V6 e-coat membranes. Formulated for normal paint fouling, PFC contains zero VOCs and unlike other UF cleaners, it only requires the addition of acid and clean water (RO or DI quality).

  • Available in 1 & 5 gallon containers
  • No expensive additional additives required for normal UF cleaning
  • Specialized cleaning formulations available upon request to combat specialized fouling
    • Biological
    • Iron Heavy
    • Metals

Membrane Cleaner Products – Synder offers a set of concentrated membrane cleaner products that are available in liquid and power formulations. The typical use concentration is a 1% solution, providing a cost effective dilution when compared to other products. The non-oxidizing biocide, Excide™ 20, is an EPA registered antimicrobial for use on membrane systems.
