Abstract
A mobile multi reservoir unit aspirates liquid with solids from septic tanks, treats immediately the liquor by a flocculent polymer and dehydrates the product by a low speed vertical centrifugal machine; the liquid is returned to the septic tank and the solid is maintained in a mud stade, easy to rake off by a rotating folding knife, followed by transfer to a storage reservoir; a pump unit enacts the material transfer from and to each reservoir in succession by aspiration and by pressure build up.
