Self-Cleaning Sand Filter Models 691 and 692

The Self-Cleaning Sand Filters offer continuous cleaning due to a granular filter media design. The media is continually being cleaned with treated water by recycling it through a fluidized bed sand washer. This filtration process reduces or eliminates the amount of additional up­ stream flocculation and settling stages.


These filtration systems have been designed to handle high solid loading capacity. A key design element of the Self-Cleaning Sand Filters is that it allows the entire bed depth to be utilized in containing entrapped solids. The reprocessed filter media acts as the final clean-up area. This system offers a liquid-solids separation at flow rates of 5 to 26 gpm/fl:2 and a suspended solid capacity of 6 to I O lbs/ft:3 (96 to 160 kg/m\ Whereas conventional


The Clarifier is a unit designed to clarify turbid and coloured waters. Simple chemical dosing allows floe to form and as It becomes heavier it settles to the bottom of the unit.
As the floe settles clean water rises and is drawn off the top and then polished via the post filter to remove any carry over.
Water Is now clarlfled and ready for use.


The clarifier Is of fibreglass construction thus corrosion free. It is mounted on a skid with post filters and asssoclated equipment for ease of transportation and installation.


Water softening and chlorination are optional extras.
