As in the terminology chemical treatments done by applying chemicals, and biological treatments are carried out by inoculating biodegrading enzymes producing bacteria or any other microorganisms (lab made).
its simple as sewage water contains germs which are harmfull if consumed by humans and also the flies sit on dirty sewage which carries the gems and sits on open food if consumed by humans can cause harm as they make it stale food
Chemically sludge is obtained when precipitating soluble or insoluble chemicals present in the water or any kind of effluent coming out of chemical industries. Generally iron was used as an precipitate pollutants present in waste water. the final product after precipitation is called chemical sludge which is filled in a land into heap or used in road construction. Biological sludge is formed when microorganisms are used to degrade toxic chemicals present in waste water. The excess biomass formed is termed as biological sludge which contains adsorbed toxic chemicals in their cells, toxic metabolites formed during degradation of wastes, dead biomass etc.
Sodium chloride, also known as table salt, is a mineral commonly used to add flavor to foods. It is also used in sewage treatment to help remove impurities from wastewater.
On average, 1 gallon of sewage sludge can contain roughly 0.2-0.4 pounds of carbon. The carbon content can vary depending on the source and treatment processes of the sewage sludge.
Common salt, or sodium chloride, is used in various food products to enhance flavor. It is also used in sewage treatment to help remove impurities from wastewater through a process called ion exchange.
Sewage treatment plants use microorganisms to destroy the biological material in sewage.

sending the sewage to a biological water treatment plant
Some common separation techniques used in treating sewage include sedimentation, filtration, biological treatment, and disinfection. Sedimentation is used to separate solid particles from liquid sewage, filtration involves passing sewage through a medium to remove impurities, biological treatment uses microorganisms to break down organic matter, and disinfection kills harmful pathogens in the treated sewage.
Here's the answer from Wikipedia. Sewage treatment, or domestic wastewater treatment, is the process of removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. This material is often inadvertently contaminated with many toxic organic and inorganic compounds. See this link for more details. http://en.wikipedia.org/wiki/Sewage_disposal

The first step in the sewage treatment process is called primary treatment. During this phase, large solids and debris are removed from the sewage through screening and sedimentation. This process helps to reduce the volume of solids and prepares the wastewater for further treatment stages, such as secondary treatment, where biological processes further cleanse the water.

A lot of treatment of sewerage and waste water uses organic means however mechanical and filtration systems are also used.
