The main difference is that biological therapies are derived from living organisms that can modify the immune response, while chemotherapy utilizes chemicals to destroy existing cancerous cells.
How do biological treatment systems work?
The first is to remove some of them by use of a pretreatment step. The second is to employ the process of gradual acclimation of the biological treatment system to the wastewaters.
How much of the organic matter is removed by biological treatment?
Biological treatment is expected to remove 85% of the entering organic matter measured as BOD and suspended solids. Most biological processes exceed this level of performance because virtually all of the biodegradable material entering is at least partially degraded.
What are the biological processes used in wetland systems?
The basic biological treatment processes used in the system include waste stabilization ponds and constructed wetland systems, trickling (or percolating) filter systems, and activated sludge systems. An aerobic stabilization pond is a large and shallow excavation in the ground, where the treatment of the waste occurs by natural processes involving the use of both bacteria and algae. In aerobic ponds, oxygen is supplied by natural surface re-aeration and by algal photosynthesis. Higher animals such as rotifers and protozoa are also present in the pond. Their main function is to predate on the bacteria, and to a lesser extent on algae, which helps in controlling the suspended solids (SS) concentration in the effluent. Ponds in which the stabilization of wastes is brought about by a combination of aerobic, anaerobic, and facultative bacteria are known as facultative stabilization ponds. The three zones in such ponds include a surface zone where aerobic bacteria and algae exist in a symbiotic relationship, an intermediate zone that is partly aerobic and partly anaerobic in which the decomposition of organic matter is carried out by facultative bacteria, and an anaerobic bottom zone in which accumulated solids are decomposed by anaerobic bacteria.
How is oxidation accomplished?
Oxidation is accomplished by adding chlorine to the pretreated wastes in an aeration basin. Oxygen from air and chlorine are the oxidizing agents. Spent activated carbon can then be recovered (partially) by the process of heating (incinerating). View chapter Purchase book.
What is the acclimation step of wastewater treatment?
The acclimation step involves subjecting the biological treatment system, activated sludge, for instance, to gradually increasing levels of the toxic substances in the full strength wastewater, until full-strength wastewater is being treated.

What is the chemical treatment of ammonia?
One version of chemical-physical treatment has been to use chemical oxidation to destroy organics, ammonia, and cyanide and then to use activated carbon to remove unreacted substances as well as partially treated substances. Oxidation is accomplished by adding chlorine to the pretreated wastes in an aeration basin.
What are the two types of biological treatment methods?
Biological treatment methods adopted for BW can be generally classified into two major divisions as aerobic and anaerobic treatments. Compared to other treatment methods, biological methods have certain advantages such as (1) treatment technology is traditional and well understood; (2) enhanced efficiency in terms of organic content removal; (3) cost-effective; and (4) environment friendly and safe. A common aerobic method such as activated sludge process is performed by allowing wastewater flow into the aerated tank and agitating the sludge to get a consortium of fungi, algae, bacteria, etc. The vigorous mixing of the biomass enhances oxygen supply, thus facilitating organic matter uptake and microbial reproduction. Trickling filters, rotating biological contactor process, and biotowers have also been employed for the treatment of BW. Their overall treatment efficiency was found to be 40%–50% ( Simante and Hill, 2015 ). Anaerobic treatment composes processes that occur in an environment devoid of air or elemental oxygen. It is characterized by the biological conversion of organic compounds by anaerobic microbes into biogas, which comprises 60%–75% methane and 25%–40% carbon dioxide and traces of other gases such as hydrogen, hydrogen sulfide, and nitrogen. The most significant anaerobic treatment processes that are prevalent in breweries are upflow anaerobic sludge blanket (UASB), fluidized bed reactors, and membrane bioreactors ( Hidalgo and Marroquín, 2019 ).
