Why saprophytic bacteria are helpful?
saprophytic bacteria are used in the sewage treatment process which are designed to facilitate and accelerate the natural decomposition process of the organic solids present in the wastes and sewage. Crack
Give one example of micro organisms in waste management?
Bacteria. Sewage consists of domestic and industrial waste and sometimes drainage from rainfall. First the sewage passes through screens to removal the larger soilds, and passes into a settlement tank. After this the liquid component and sludge are treated separately. Aerobic bacteria digest, breakdown and oxidise organic components of the liquid component in oxidation ponds(liquid trickled from a rotating arm over stons with bacteria on them) OR an activated sludge tank(airbubbled through bacteria and sludge). This is because these bacteria need oxygen for repiration/metabolism to break down the sludge efficiently. The digestion of more soild sludge is carried out by anaerobic bacteria in tanks, producing a mixture of carbon dioxide and methane. The digested sludge may be used as compost/fertiliser to grow plants. The methane can be used as fuel source at the sewage treatment plant to heat the plant or to produce electricity. Sewage treatment reduces the organic content and suspended material to a level that does not harm a river receiving the effluent.

How do you put public works in a sentence?
Taxes are used to finance such public works as highway construction and sewage treatment plant construction.
A new wastewater treatment plant opens in an area where raw sewage used to be dumped directly into a bay What type of pollution will be reduced the most by the new plant?
Bacterial
What work do they do at a sewage treatment plant?
Large items of waste are firstly removed from the sewage intake to prevent blockages throughout the cleaning process. Grit and smaller items are then removed using a filter, before chemical treatment is used to purify the water.
Why air along with microorganisms bubble into water in sewage treatment plant?
If microorganisms are used in the water treatment plant then it is necessary to provide oxygen to them and make the sludge degradation through them so air is bubbled for oxidation as well as for microorganisms.
Role of micro organisms in sewage treatment?
Use of microbes in sewage treatment and maintenance of sewerage system has been evolved and portrayed as a promising option, and such products and services have been offered by many companies. In some technologies, along with naturally occurring bacteria, genetically modified bacteria are also used. Such services are for maintenance of sewage pipelines and sewage treatment infrastructure and also treating some of the pollution loads. All these technologies work on oil & grease trap, drain, septic tank to prevent clogging of drains and reduce the loads of BOD, TSS & FOG.
What is stp and etp in water treatment?
STP stand for Sewage Treatmnet Plant and ETP stands for Effluent Treatment Plant and they both help in saving water by treating the wastewater such as sewage water like Human excreta waste, Kitchen Drainageand more. There are various type of these machines with different capacities like 5 KLD, 10 KLD and more. The machines used here will bring high ROI as they safeguard water,untreated water which further can be used in agricultural industries,manufacturing industries vice versa. I hope this will clear all your doubts.
How expensive is sewage treatment?
not very. It just depends on the type of treatment that is being used
Where does the water from our drain go?
There are usually two kinds of drain, sewage and stormwater. Sewage runs from your toilet to a treatment plant that usually removes solids and cleans the water well enough to be put back into rivers and waterways, and eventually, the ocean. Stormwater takes the water runoff from rooftops and streets and runs it into waterways without any purifying or cleaning. There may be some rough grills and gratings to capture floating debris like plastic bottles. In some areas without sewer pipes septic tanks are used to collect sewage. These tanks are regularly pumped out and the sewage is taken to a treatment plant.
In a water treatment plant bacteria are used to digest material in the water however these bacteria can be harmful to humans because of this what other steps must be taken in treatment of water?
chemicals must be added to kill the bacteria after they have finished digesting
