The attributes of the waste can be measured through biochemical oxygen demand (BOD), which gauges the quantities needed by bacteria and other kinds of microorganisms to oxidise the organic material contained in the sample for a five-day period.
- Primary - Aside from being the simplest method among the three, this is also the least effective. It just allows solids to settle through suspension and then form sludge. Essentially, it only removes one-third of the BOD and almost nothing of the dissolved components. It should be noted, though, that the use of digested elements as fertilisers have been discouraged due to their frequent exposure to toxic substances derived from industrial companies.
- Secondary - In this method, the effluent is exposed to aerobic microorganisms and oxygen. It is instrumental in breaking down most of the organic stuff into harmless substances like carbon dioxide. Take note that when the first treatment is reinforced with this one, 90 percent of BOD can be eliminated. In fact, as soon as chlorination is done, the water may be returned to the local surface.
- Advanced - While combining the primary and secondary procedures is effective in lowering the demand for biochemical oxygen, most of the phosphorus and nitrogen will remain. These inorganic elements can also help prevent the growth of algae, which is otherwise called eutrophication. When water undergoes this third stage, such a condition will be avoided.
