Why does water in an aquirium go down?

Because some of the water is evaporated into the air. Salt water is evaporated much faster than fresh water.


How much water is in sludge from a sewage treatment plant?

I may be wrong but i do believe there is 0.8% water in sludge 60% of the time, all the time.


What is sewage treatment?

Sewage sludge is the solids that are left over at the end of the sewage treatment process. The products of sewage treatment are: clean water which is released to the environment and sludge. Sludge consists mostly of cellulose (in the form of dead bacteria) and water. Cellulose is also what wood is made from; it does not decompose easily which is why the cellulose has not been broken down in the sewage treatment plant. The water content of sludge will vary from 30% water to 90% water depending on how much the sludge has been dewatered at the treatment plant. If you can imagine the appearance of a magazine after it had been through a food processor with just enough water to keep it soggy, that is what dewatered sludge will look like. Sludge should not be though of as concentrated sewage but it is still not safe to handle unless it has been processed in some way to kill harmful bacteria and viruses that are likely still living in the sludge. In North America most sewage sludge is sent to a landfill site; other options include further processing in 'Sludge Lagoons,' further biological processing and methane harvesting in an enclosed container; or processing into dry pellets for use on gardens. If sludge is sold to the public it will be heat processed and/or dried to kill bacteria. It will also be tested for contaminants such as dissolved metals that may be present in the raw sewage and not removed by the treatment process.


What temperature is saturation reached?

it doesn't depend on the temperature but depends on how much water was evaporated


How much does 1 cubic yard of sewage sludge weight?

Depends on how dewatered it is
