A 28 GPM SLOW SAND FILTER AT A NATIONAL PARK

Blue Future Filters Inc. provides package plant slow sand filters to help small communities such as 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 14,400 gpd and up, using extra heavy-duty polyethylene roto-moulded components. Additional output can be achieved through installing multiple units in parallel. These 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.

The following table lists models, flow rates in gallons per minute and gallons per day and footprint size for each filter. For more detailed information on these filters, see our SSF-Series Installation and Maintenance Guide.

* SSF 8 uses nestable filter tanks for inexpensive shipment for bulk or international orders.

** On SSF 10, more tanks can be manifolded for higher gpd output.

All sizes based on U.S. specifications. For international rates and sizes, please contact us. Media is obtained locally.
