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.

What is bio waste?
Biodegradable waste is a type of waste which can be broken down, in a reasonable amount of time, into its base compounds by micro-organisms and other living things, regardless of what those compounds may be.
What type of organism that could use waste products in photosynthesis?
Respiring organisms, these can be from humans such as ourselves to micro-organisms, such as bacteria. There is one 'waste' product of photosynthesis - oxygen, glucose is all used or stored by the plant. Oxygen is not a complete waste, as it is used in plant respiration, however, the oxygen released from the plant can be used in respiration in other organisms.
Where does the waste from sea animals go?
The waste from marine animals is returned to the water in which they live. It forms part of the food chain as it is ingested by the micro-organisms that in turn become food for larger marine life.
