Features of the Econo-DAF (2)









           • Does not require sludge removal chain-and-



                  blade scrapers, since the sludge is removed



                  over the top by closing the outlet valve




                  occasionally for a few seconds using a



                  simple timer. This saves significantly in capex




                  and maintenance requirements




           • The Econo-DAF has been designed to



                  handle both floating and settling solids,




                  should the flocculated solids also contain



                  some heavier material.
