http://americanwatercollege.org • • This question comes from the California Wastewater grade 4 certification exam sample questions that can be found here: http://www.swrcb.ca.gov/water_issues/... • • The problem reads: • A 2 meter belt press is being used to dewater anaerobically digested sludge (3.8% TS) at the rate of 75 gallons/min. It is operated 6.5 hours per day. The feed sludge is conditioned with a polymer solution and then fed to the press. A 25 cubic yard truck full (level road) of sludge cake (20.5% TS, bulk density 65.8 Lbs/ft3) is hauled away at the end of each day. Calculate the percent solids recovery.
