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.
How are sewage and septic tanks alike?
Sewage is a waste water from houses and other institutions, industries while septic tank is a treatment unit for sewage from small communities
When solid waste produced by a sewage-treatment plant is called .?
The solid wastes from a sewage treatment system are determined by the degree of treatment provided:Septic tanks: Organ sludge composed of fecal matterPrimary treatment systems: Mainly settled fecal matterSecondary treatment: Solid materials collected at the intake, aerobic sludges from aeration ponds, anaerobic sludges from digestersTertiary treatment: same as secondary treatment.
How do microorganisms help in sewage treatment plants?
There are two types of micro organisms at work in a sewage treatment plant., aerobes (oxygen needing microbes) and anaerobes (microbes that do not need oxygen) The anaerobes are mixed with the raw delumped sewage in aerated basins. They rat up the small particles and dissolved organic material present in the sewage to produce carbon dioxide and their own microbe bodies. The Anaerobes are stained out and the sewage is discharged to the effluent discharge. The removed aerobes are then put in the anaerobic digestor tanks where anaerobic bacteria eat them up creating methane which is collected to power the plant. Eventually all the bacteria in the digestor are consumed leaving inert materials.
How long does it take bacteria to break down raw sewage?
It depends. Its a few days at least. We use bacteria at our sewage treatment plant to eat the sludge. Sludege is what you are saying, right? All of the raw sewage goes though filters then the sledge that collects is eaten up by living bacteria. If your talking about the RidX for septic tanks it will take a few days to multiply and eat sludge in the botton of the tank.
Are sewage tanks good for the environment?
As long as sewage tanks do not leak, they make no difference to the environment. Many homes across north America are not on municipal sewer and therefore have to have sewage tanks to separate waste before the black water goes to the septic field. In good shape these do not hurt the environment.
Not a storage pool for water?
Clean drinking water is usually stored in large tanks. Sewage treatment on the other hand refers to the process of removing the contaminants from the waste water.
How does sewage water move?
Sewer pipes usually flow downhill or into holding tanks where the sewage is pumped out using big pumps.
What are septic tanks?
Septic tanks are large tanks placed in the ground used to dispose of sewage in homes that are not connected to a city waste system. The sewage goes into the tank and is broken down by the bacteria in the tank. The liquid flows out of the tank into special pipes that allow the water to soak into the soil.

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.
