Wastewater treatment involve a few number of key components like physical treatment which are filtering and screening courses. The biological process which is known as oxidation of lagoons and ponds and also chemicals. The chemical that is needed for the wastewater treatment procedures is more aggressive especially if the water is inside large quantities than the average municipal drinking waters. This will make it a much safer and proper storages for the chemicals during the process. When it comes to chemical tank sludge, companies always follow the process from the first step until everything has been clear and safe.

The operating procedure of aerobic is much greater than other types. It consumes lots of energy and maintenance costs like motors, pumps and blowers which is essential in adding oxygen to it. New technologies have advance and created non electrical aerated filter systems. It used air currents naturally rather than electrically operated equipment and machinery.

The thickeners will somewhat resemble a clarifier and the addition of having their own stirring mechanism. Thickened out muds that has only ten percent solid will receive additional processes while the excess will undergo an overflow and returned back to the sewage process.

The dewatering course would be reduced by undergoing filtration, evaporation or centrifugation to minimize the costs of transportation during disposal or improve the suitability for the composting stage. The centrifugation will be the preliminary step in order to minimize the volume of sludges for subsequent evaporation and filtration.

Mesophilic anaerobic digestions or known as MAD is widely used by many companies for treating out wastewaters. The sludge will be stored in huge tanks for a number of twelve days to allow it to digest and perform the four phases of digesting it. In this technique, the complex sugars and proteins will be broken down and form a single compound like methane, carbon dioxide or water.

The distribution of pathogens that would kill the parasites will be placed in an insulating blanket which are composed of aerated piles. The moisture percentage of composting materials must be about fifty percent. However, the temperature must be higher for the reduction of pathogen where the wet sludge will be raise above the moisture contents.

The procedure can be done in facility for sewage treatments or other locations. This will depend upon the owner of the company and where the wastewater will travel after the procedure. The process will also require a complete set of apparatuses and technologies to fully control the flow of operation.

Drying beds is commonly used in many countries especially those who are still developing. This is a very cheap technique to dry out the sludge from sewages. The drainages will be captured. The drying bed will only be left uncovered and unchecked.

The stage is known as endogenous respiration. The reduction of solids happens in this stage. Due to aerobic digestions happen much quicker than anaerobic, the costs of capital becomes lower.
