Treating wastewater is a valuable process and a necessary function to all communities.

Water released back into the environment requires effective treatment or damage will result to people's health and the surrounding ecosystem.

The importance of removing solids and BOD in wastewater is just as important to a small office park as it is to an entire city.

Wastewater treatment utilizes several delicate chemical processes to achieve an acceptable quality of water, which is analogous to an acceptable quality of life.

how is bod removed from wastewater?

Wastewater contains many elements which break down into two groups, organic and inorganic substances.Organic substances include dish soaps, fecal matter, and food particles.

These elements break down and feed bacteria which exist in the septic system. Bacteria naturally decomposes organic matter, but requires oxygen to do so.

The larger and more numerous the organic matter, the more oxygen required to eliminate organic matter. The rate at which wastewater requires oxygen is known as the biological oxygen demand (BOD).

BOD is a crucial factor in refining wastewater.

The bacteria are important for breaking down substances, however too much BOD can cause unwanted amounts of bacteria.

It can also drain receiving waters of oxygen which can kill fish and harm the environment. Therefore it is important to control the level of BOD at every stage of the treatment process, and to remove as much as possible in the final stages.

Sewage to Blame For Dead Fish

Many septic systems have both an aerobic and anaerobic process, while others focus on reducing the need of BOD altogether.

Inorganic solids take longer to breakdown and can clog various parts of the septic system.

Inorganic material and other TSS(Total Suspended Solids) are most effectively taken out of wastewater through the use of effluent filters. These filters will catch fine particles, drastically improving the wastewater's quality.
