Blue Future Filters Inc. provides package plant slow sand filters to help small communities such as rural subdivisions, parks, mobile home parks, camps and retreat centers meet the requirements of the U.S.E.P.A.'s Surface Water Treatment Rule. Our systems cost one third to one half that of other treatment systems with the added benefits of no power requirement, no chemical requirement, and lower operator costs.

  • Approved EPA technology
  • No electricity, no chemicals
  • Basic operator certification (instead of intermediate)
  • Half the cost of conventional or DE
  • Advanced monitoring and cleaning means no resanding

Slow sand filtration offers a cost-effective approach to water treatment where surface water is the source and bacteria, Giardia, Cryptosporidium and turbidity are the problems. Blue Future Filters offers a series of Blackburn & Associates-designed community sized slow sand filters producing from 6,000 gpd to 12,600 gpd and up, using extra heavy-duty polyethylene roto-moulded components. Additional output can be achieved through installing multiple units in parallel. Beyond 50 gpm, Blue Futrue Filters offers bolted steel filters up to 2,000 gpm. Both types units can be installed in a matter of days without specialized tools or equipment at a fraction of the cost of concrete or steel. This means additional savings in that installation can accomplished "in-house" without costly out-sourcing for skilled labor.

Net result: a savings to your organization of up to 70% on water treatment systems. Blue Future Filters provides the filters, manifolds, valves and complete, clear instructions on installation and maintenance. Along with our partner, Blackburn & Associates, we work with health department officials to facilitate your installation. We also offer on-site consultation worldwide at time of installation (recommended), as well as technical support by phone, FAX, or e-mail. With your water report, description of site, climate information, and quantity requirement we can recommend the proper filter(s) for your needs.

We can also assist in pilot studies, if necessary, including providing prefabricated pilot scale slow sand filters that faithfully reproduce operating characteristics of our larger plants.
