Kalamazoo wastewater treatment plant On October 22‚ 2011‚ a group of students from the class of CHEG 2610 visited the Kalamazoo Water Reclamation Plant (KWRP) to learn more about the process to treat wastewater around the Kalamazoo area. To clean up the water‚ the KWRP used the Activated Sludge‚ which is a biological treatment technique in which a mixture of wastewater and biological sludge (microorganisms) is agitated and aerated. The Kalamazoo wastewater treatment plant has been renewed since

bacteria‚ which are mixed with wastewater. The bacteria consume and remove aerobically biodegradable organic substances from screened; or screened and presettled wastewater in an aerated tank. The organic pollutants in the wastewater are used by the bacteria to grow and transform it to energy‚ water‚ CO2 and new cell material. Activated sludge systems are suspended-growth type and are used in conventional high-tech wastewater treatment plants to treat almost every wastewater influent such as ‚ brownwater

Wastewater recycling‚treatment in industry Purpose- Industrial activity worldwide uses 22% of the roughly 3.8 billion m3 of water consumed by human activity. So industry has a great need for water but given the tensions over water and the tougher legislation‚ it cannot continue to drain all this water from our planet’s resources. This is why the recycling of wastewater has become one of its top priorities. Water is often an essential part of industrial production. In the context of an ever more

27-09-2009 The plant currently does not comply with the DWA wastewater discharge standards. There are major challenges with respect to operation‚ maintenance and some equipment status at the plants. Some of the problems identified that are hampering the non-compliance of the final effluents are as follows: • Flow meters are not calibrated (incorrect flow readings) and this makes it difficult to optimize the plant with respect to flows into different modules‚ i.e. Activated Sludge plant and the trickling

------------------------------------------------- Treatment of industrial wastewater The various types of contamination of wastewater require a variety of strategies to remove the contamination Brine treatment Brine treatment involves removing dissolved salt ions from the waste stream. Although similarities to seawater or brackish water desalination exist‚ industrial brine treatment may contain unique combinations of dissolved ions‚ such as hardness ions or other metals‚ necessitating specific

DEFINITION ANAEROBIC POND Anaerobic ponds are deep treatment ponds that exclude oxygen and encourage the growth of bacteria‚ which break down the effluent. It is in the anaerobic pond that the effluent begins breaking down in the absence of oxygen "anaerobically". The anaerobic pond acts like an uncovered septic tank. Anaerobic bacteria break down the organic matter in the effluent‚ releasing methane and carbon dioxide. Sludge is deposited on the bottom and a crust forms on the surface as show in

SEWAGE TREATMENT Sewage is a mixture of domestic and industrial wastes. It is more than 99% water‚ but the remainder contains some ions‚ suspended solids and harmful bacteria that must be removed before the water is released into the sea. The treatment of wastewater is divided into three phases: pretreatment‚ primary treatment and secondary treatment. Pretreatment Large solids (i.e. those with a diameter of more than 2cm) and grit (heavy solids) are removed by screening. These are disposed of in
