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

Sediments that settle out during water treatment?
sewage or sludge.
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 is a filtration plant?
filtration plant is a division of the Public Works Department. Its responsibility is the treatment of water to make sure it is safe and reliable
How does water polluition work?
Sewage is a term for the waste of people and animals. Normally, sewage is sent off to a treatment plant, and kept entirely separate from drinking water. If sewage was to enter the water supply, it would make people extremely sick.
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.

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.

What are the NEWATER plants?
It is a treatment plant which turns sewage water into clean water
Waste water from homes is cleaned and put in a type of plant what type of plant is it put in?
its called a water sewage treatment plant.

What are the downsides of living near a sewage treatment plant?
Sewage treatment is an essential process in a more advanced society. Untreated sewage can reenter the water system and spread disease. Land around a sewage treatment plant would be cheap, as it is a less desirable area to live, because of the bad smell.
What is an equalization tank in a sewage treatment plant?
Equalization tank for wastewater treatment refers to a holding tank that allows for equalization of flow. An equalization tank may also be used as a staging area where chemicals, activated sludge, or other agents are added into the waste-water treatment process.
When we do our dishes where does the water go?
Down the sewers to the sewage treatment plant, just like when we flush the toilet or take a shower or brush our teeth or wash our hands. In many cities runoff from the streets also goes into the same sewers, but as heavy rains can cause the sewage treatment plant to overflow and allow untreated sewage out, there is often a separate sewage system for this that does not go to the sewage treatment plant.
During primary treatment at a sewage treatment plant?
The bacterial bugs eat the dirty things from the water
What is the sewage and wastewater treatment industry?
Work in this category primarily entails contracts related to water and sewage treatment plant construction and renovation, including filtration and desalinization plants.
