Wastewater treatment plant switching from anaerobic to an aerobic system
The Pratt wastewater treatment plant in Pratt, Kan. is looking to improve the efficiency of its digester when it switches from anaerobic (non-oxygen) to an aerobic (oxygen) system. Pratt City Manager Dave Howard said the belt press or digester uses biological organisms (microscopic bugs that eat waste) to process the waste and clean it up. The microscopic organisms will be able to work more efficiently with more oxygen in the system. The city was already dealing with problems trying to get rid of the sludge in the system and they hope this switch will fix the problem. Howard said the town would usually haul the product to area fields where it was land applied, but disposal was a major problem for the city.

Hurricane Sandy leaves behind expensive cleanup at sewage plant in N.Y.
The Bay Park sewage plant is looking at the expensive effects left behind by Hurricane Sandy. A greenish-gray soup of partially treated human waste is currently flowing in the water coming out of the plant in Nassau County, N.Y. The water symbolizes the environmental and public health concerns the state has to deal with after the disastrous storm struck the east coast. Since the storm, millions of gallons of partially treated raw sewage has flowed into waterways in New York, exposing major flaws in the region’s wastewater infrastructure. Gov. Andrew M. Cuomo has estimated that about $1.1 billion will be needed to repair treatment plants in the state.

The Kitsap County commissioners have awarded a construction contract for the $29.6 million upgrade to the Central Kitsap Wastewater Treatment Plant. The plant is scheduled to start construction at the beginning of 2013. McClure & Sons of Mill Creek was awarded the contract by bidding over $3 million less than engineering estimates.
