Pumps on an effluent treatment system
For years, farmers whose main source of income is raising cattle, chickens or pigs simply used high pressure hoses to flush the waste from raising barns or feed lots. The waste slurry was flushed into large holding ponds somewhere on the farm. In these ponds the solids settled to the bottom and the effluent remained on top of the body of water. Eventually, the ground water for miles around the ponds becomes contaminated, which, in time, contaminated the air and groundwater. Once the E.P.A. became aware of this situation, they insisted, under the Clean Water Act, that the ponds be sanitized and no additional untreated waste be discharged into the water.
To correct this problem, Burrows Engineering in Woodbury, Tennessee designed the Immobilized Cell Bioreactor System to clean the waste and the sludge being flushed into the ponds. The I.C.B. System removes the solids by using carbon filters. The effluent is then pumped through a Venturi Eductor, which draws air into the effluent stream as it is being pumped to a chemical treatment section. Burrows Engineering tried a number of pumps on the effluent treatment system. However, many of the pumps that were tested could not maintain a constant flow and pressure or draw air into the system.
Tim Nedrow of Nedrow & Associates, the NEMO® Representative in Tennessee, contacted Burrows Engineering and evaluated the system. Tim suggested that a NEMO® NM038SYO1L06B be utilized for their I.C.B.
With much success, this system is now being used at a raising farm in New Holland, Pennsylvania which has a population of approximately 9,000 pigs. NEMO® pumps proved to be the answer to Burrows Engineering's system problems. Ken Burrows, President of Burrows Engineering, explained that E.P.A. pressure to clean the waste ponds will result in an urgent need for systems such as the I.C.B., where raising barns or feed lots are located. Burrows has excellent O.E.M. potential with NETZSCH because the NEMO® pump is a dependable and durable key component of their system.
