Sewage treatment plant is built to treat the waste materials before it's discharged in the natural environment. The resulting sludge produced as it passed through the sewage treatment is organic in nature and produced beneficial amounts necessary for plant nutrients like nitrogen, phosphorus and other essential elements. The main objective of the sludge produced is to use it as eco-friendly fertilizer or soil conditioner for farming purposes. In the treatment of sludge there exist a number of digestion procedures used to minimize the amount of organic matter and also the amount of disease-causing microorganisms which are present in the solids. The widely used treatment options are anaerobic digestion, aerobic digestion and composting.
The anaerobic digestion method is a bacterial process that is carried out without oxygen. The generated biogas that have high contents of methane can be used for heating up the tank, to run the engines or micro turbines and various other types of on-site processes. In large sewage treatment plants, the energy produced is sufficient to produce more electricity required by the machines. The aerobic digestion is a bacterial process that happens in the presence of the oxygen. In the aerobic process, the bacteria quickly absorb all of the organic matter and then transform it into CO2. If there is insufficient organic matter, the bacteria will die and will be used up by other bacteria as food.
One more commonly used treatment is composting. Composting is likewise an aerobic procedure that includes the mixing up of wastewater solids together with sources of carbon such as straw, sawdust or chips of woods. With oxygen being present, the bacteria absorb and break down the wastewater solids and also the added elements of carbon sources. With this particular process, large amount of heat is created. Composting also is used to make fertilizers for farming use. Compost materials are organic matter rich in nutrients needed for plant growth.
The bacteria have a vital part in the processing of sewage. In the normal sewage treatment plant, to enhance the function of aerobic bacteria, o2 is added. This is to assist in preserving the superiority over the anaerobes. The aerobic bacteria need oxygen in order to survive while the anaerobes can survive even without the support of o2. The facultative bacteria in contrast, either with the presence of the oxygen or with the absence of the oxygen. The microorganisms and the corresponding enzymes systems are the one responsible for several different chemical reactions created in the degradation of organic matter. The enzymes are created as the bacteria metabolize, grow and break down. These enzymes are abundant in molecular weight proteins. All sewage treatment plant should be designed to take optimum use of the organic materials by the activity of the bacteria.
The sewage treatment plant are getting more evident because of the deteriorating water sources, the rise of cost in wastewater disposal, and also the tighter discharge rules that give rise to the decline in allowable contaminant levels in waste streams. Effective wastewater collection as well as sewage treatment are really important to preserve the natural environment and protect the public health.
