BIOLOGICAL TREATMENT

Biological treatment is the breakdown of suspended or dissolved organic substances in the wastewater by bacteria and the conversion of collapsing biological flows into fixed inorganic compounds that remain in the liquid or escape to the atmosphere as gas.
Generally, more than 99% of the waste is composed of water and only the remaining contaminants. Pollutants can be dissolved in water, or they can be suspended as solid matter..
The treatment method that can be used to remove these substances according to their properties also changes. For example, it can be said that the most effective method for removing organic pollutants is biological treatment..

The basis of biological purification is that organic pollutants are repeated in optimum conditions through the control of biofollocations and mineralization processes in order to eliminate them in nature..

Thus, the reactions in nature are accelerated and carried out in a shorter period of time in a safe environment.
The aim of biological purification is to coagulate non-precipitant colloidal solids in wastewater
to resolve and stabilize organic matter. In domestic wastewater treatment, as well as organic matter content, nutrients such as nitrogen and phosphorus are also eliminated in biological treatment..

CONVENTIONAL TREATMENT

Population growth and industrialization also bring about increases in water consumption. The increase in water consumption leads to a decrease in Clean Water Resources. In this case wastewater treatment is becoming more and more important. Biological treatment processes are of great importance in wastewater treatment.

MBBR TREATMENT

Moving bed biofilm reactors were developed as a compact treatment alternative to conventional activated sludge reactors in Norway in the early 1990s.

The main idea in developing these reactors is to combine the best features of activated sludge and biofilm processes in a single reactor. Moving bed biofilm reactors are continuously operated and consist of elements called carriers.

Unlike most biofilm reactors, moving bed biofilm reactors use the entire tank volume for biomass development, and unlike activated sludge reactors, no sludge recirculation is required.
Both reactor volume and space requirement are relatively low carrier elements specially designed to provide a large surface area for the development of cohesive microbial biofilm.
High surface area carriers provide a high amount of space for the adsorption and development of microorganisms .

In this way, it is possible to obtain a high concentration of bacteria in the reactor without any significant increase in the concentration of MLSS from the final precipitor.
This increases the biological treatment capacity for a given reactor volume.
High sludge age in moving bed biofilm reactors provides a suitable environment for the development of slow growing microorganisms such as nitrification bacteria.

MBR TREATMENT

Membrane bioreactors (MBR) used for wastewater treatment have been used in developed and developing countries at an increasing rate in the last 10 years.

In the coming years, it is estimated that many conventional wastewater treatment plants will transform technologies into mbrs and as a result, the final settling pools will be eliminated.
Mbrs are biological processes in suspension growth mode where purified water and biomass are physically separated by membrane equipment.

Membrane bioreactors (MBR) are an improved form of classical activated sludge systems. It is the combination of biological reactors and membrane technology. After biological treatment, separation is performed by using ultrafiltration (UF) or microfiltration (MF) membranes instead of settling pool.

Membrane bioreactor type ( MBR ) wastewater treatment plants use a new wastewater treatment technology consisting of a membrane ultrafiltration and aerobic biological treatment reactor.

Aerobic Membrane Bioreactor Systems (AeMBR) are widely used in the treatment of domestic and industrial wastewater. Biological reactions occurring in the presence of oxygen and organic substances are eliminated and simultaneously using membrane filtration of the separation of solids is provided.
