Filters are essential to keeping your reverse osmosis membrane system clean and functioning, resulting in pure, superior water. Consolidated Water Solutions has a wide variety of prefiltration options to choose from. We stock thousands of prefilters in our warehouse, so we can ship most orders within 24 hours.

Why Are Filters Important?

Prefiltration catches some bacteria and suspended solids before they reach your industrial membrane system. This helps achieve low SDI ratings and protects against membrane fouling, ensuring maximum performance and longer life. The filtration process results in lower operating costs and reduced capital expenses.

Types of Filters We Offer

Pretreatment Filters | Consolidated Water Solutions

Cartridge Filters

Cartridge filters are best if you’re filtering sediment or similar-type particles. They are preferable for systems with contaminations lower than 100 ppm. Cartridge filters are normally designed for disposal and must be replaced when the filter is clogged.

We offer:

  • Water Grade Meltblown Cartridges
  • High Performance Meltblown Cartridges
  • Absolute Rated Meltblown Cartridges
  • String Wound Cartridges
  • Pleated Filter Cartridges

Bag Filters

Bag filters are frequently used for dust removal in industrial applications. These filters flow from the inside to the outside. While they don’t catch as much as cartridge filters, they generally last longer.

We offer:

  • Standard Felt Liquid Filter Bags
  • Standard Mesh Liquid Filter Bags
  • High Efficiency Multi-layer Liquid Filter Bags
