Watch discharge <br /> pipe to determine correct flow. Pipe should run about "1/3 of a pipe full" in most cases. <br /> Continue scraping procedure at short intervals to allow sludge to be picked up by the <br /> pump. Sludge break-up must be done gently or it will rise to surface in chunks. If this <br /> occurs, the floating chunks must be broken up with a stick or paddle into small pieces of <br /> the skimmer to pick up and return to aeration tank. When scraping the clarifier, open <br /> the air line valves to the skimmer and sludge return pump. <br /> pcs lc.&jt3-sp.main,startup-1-3 <br />
