Motors will not run: <br /> (a) General power outage <br /> (b) Fuses blown - replace; reset circuit breaker. <br /> (c) Motors overloaded — push reset button; check overload heaters if reset <br /> does not start motor. <br /> 2. Excessive Foaming: <br /> (a) Over aeration - reduce running time <br /> (b) Lack of solids - (usually found only during first few weeks of operation) <br /> (c) Excessive use of detergents - eliminate before they enter the plant. <br /> 3. Equipment will not work on automatic: <br /> (a) Failure of time clock - have electrician check <br /> (b) Overload may be released - push reset buttons. <br /> 4. Sludge accumulation on top of settling tank: <br /> (a) Airlift skimmer not returning. <br /> (b) Sludge return pumps not returning or not returning enough — check <br /> hoppers for sludge build-up. <br /> (c) Excessive amount of grease - check grease trap (if one is installed <br /> upstream of the treatment plant) and clean, if necessary; or eliminate <br /> before entering plant. <br /> (d) Refer to special section on "Sludge Problems " <br /> 5. Large quantities of solids going over effluent weir: <br /> (a) Sludge pumps not returning or not returning enough - check air lines and <br /> pump tube for blockage. <br /> (b) Plant overloaded - check influent flow and volurne and have influent <br /> analyzed for B.O.D. and suspended solids. <br /> Note: Refer to equipment manufacturer's bulletins for more specific maintenance and <br /> operating instructions. <br /> pcsioKm-trouble-,,hoot,aidc-1-2 <br />
