ABSTRACT:
The present invention discloses a new and useful filter aid dispensing arrangement for use in dispensing a powdered filter aid to uniformly precoat a filter media in a liquid filtration device where the arrangement includes: a container having a sidewall defining an open end to receive powdered filter aid and a closed end; apertures advantageously located in said sidewall to allow excess powdered filter aid to flow out of the container when a predetermined quantity of powdered filter aid is accumulated in the container where the container is in a first position; a handle to position the container in a first and a second position; a slot provided in transversely aligned relation in the sidewall adjacent the open end of the container to receive a bracket disposed in vertically aligned relation to secure the container in the second position; a baffle located within said container adjacent the open end and disposed across the container; a fluid inlet tube provided in the sidewall to admit a liquid tangentially when the device is in the second position; a liquid deflector located within the container at the outlet of the fluid inlet tube to direct fluid carried by the fluid inlet tube tangentially and toward the closed end of the container to thoroughly mix liquid with filter aid contained within the container to form a precoat slurry where the precoat slurry is dispensed from the container through the aperture, slot, and open end of the container.
