Biological Wastewater Treatment Market Research, 2031

The global biological wastewater treatment market was valued at $9.1 billion in 2021, and is projected to reach $15.1 billion by 2031, growing at a CAGR of 5.2% from 2022 to 2031. The action of microorganisms in biological wastewater treatment is intended to degrade pollutants dissolved in effluents. These substances are used by microorganisms to survive and reproduce. Pollutants are converted into nutrients.

Biological Wastewater Treatment Market

Demand for wastewater treatment facilities is expected to increase during the projection period due to declining freshwater supplies and growing water shortages. Due to the scarcity of freshwater resources and the increased demand for water in diverse desert locations, more wastewater treatment facilities are being constructed globally. The rise in industrialization and increased demand for water are expected to be the major driving factor in the market's growth. Many industries require large amounts of water for day-to-day operations, so with the help of biological wastewater treatment, the industries can reuse the water for effective work over and over again. All of these factors contribute to increased industrialization, which drives significant growth in the biological wastewater treatment market .

The high cost of wastewater treatment is expected to stymie the biological wastewater treatment market growth. The most significant market restraint is the high cost of sludge movement, operational costs, and other potential costs associated with water purification. Furthermore, biological wastewater treatment offers a variety of solutions to meet the requirements, but it necessitates a sufficient amount of space for storing gallons of water as well as the necessary machinery. The system's size and cost are expected to stymie market growth during the forecast period.

The primary filter material for many biofiltration wastewater treatment systems is porous concrete. The helpful bacteria that can degrade many of the harmful chemicals in the wastewater are produced in greater quantities owing to this filter medium. It will be put into a bioreactor, where it should begin to break down some of the hazardous substances in the water, which can range from proteins and lipids to other organic molecules. Hydrogen, sugar, and alcohol are some other pollutants that should be easily broken down in this system. Additionally, Globally, numerous government agencies and non-profit organizations are launching numerous campaigns to raise awareness of the importance of consuming clean, safe water during this chaos. Such measures are raising the need for water treatment services, which throughout the projection period is raising the growth of biological wastewater treatment.

The global biological wastewater treatment market is segmented on the basis of process, type, and region. On the basis of process, the market is segmented into aerobic, anaerobic, and anoxic. On the basis of type, the market is classified into municipal waste and industrial waste. By region, the market is analyzed across North America, Europe, Asia-Pacific, and LAMEA.

The biological wastewater treatment market is segmented into Process and Type.

Biological Wastewater Treatment Market by Process

By product type, the aerobic sub-segment dominated the market in 2021. Aerobic treatment is a form of biological wastewater treatment that occurs in the presence of oxygen. Aerobic biomass breaks down organics in wastewater to produce carbon dioxide and new biomass. Aerobic treatment methods can be used to polish anaerobically pretreated wastewater to reduce biochemical oxygen demand (BOD) and total suspended particles as stand-alone systems for treating raw wastewater (TSS). Aerobic methods can also be utilized to remove nitrogen and phosphorus as a biological nutrient removal system (BNR). These are predicted to be the major factors affecting the biological wastewater treatment market size during the forecast period.

Biological Wastewater Treatment Market by Type

By type, the industrial waste sub-segment dominated the global biological wastewater treatment market share in 2021. Growing number of industries, worldwide, and large volume of wastewater generated from the industries has boosted the demand for biological wastewater treatment. Biological treatment of industrial wastewater is a process in which bacteria and other microorganisms consume organic compounds as food. One or more species of bacteria, rotifers, fungus, rotifers, or other microbes can feed on almost any organic material. The sewage technique is widely utilized for secondary wastewater treatment in both industrial and domestic settings. This method is commonly used to cleanse waste streams with a high organic or decomposable content, such as municipal sewage; wastewater produced by pulp and paper mills or meat processing companies; and industrial waste streams containing carbon particles.

By region, North America dominated the global market in 2021 and is projected to remain the fastest-growing sub-segment during the forecast period. The North American market is predicted to increase at a steady rate throughout the forecast period. The U.S. leads the market in this area followed by country Canada, and Mexico. The scarcity of drinking water has resulted in a global need for clean and pure water. Water spreads several diseases, necessitating the provision of clean drinking water and bolstering the growth of the wastewater treatment services industry. The North American market has expanded as a result of strong environmental regulations limiting the discharge of waste effluents into bodies of water. Water bodies in the country are polluted and devoid of life as a result of growing levels of water pollution.

Analyst Review

The biological wastewater treatment industry is expanding as the government in numerous nations are enforcing strict laws on companies and power plants for regulating emissions into water bodies. In addition, wastewater treatment systems transform waste streams for secure disposal or re-use in municipal or environmental facilities. As waste streams differ from one production line to the next and discharge compliance regulations differ across geographies, wastewater treatment is a specialized procedure that should be tailored to the circumstances. However, the high costs associated with proper disposal of contaminated water might become a restraint in the growth of the biological wastewater treatment market. In addition, having operational treatment plants is now necessary for businesses to meet severe environmental criteria. Due to strict regulatory requirements, the market for wastewater treatment plants is expected to have strong demand over the forecast period.

Among the analyzed regions, North America is expected to account for the highest revenue in the market by the end of 2031, followed by Asia-Pacific, Europe, and LAMEA. Rapidly increasing population and urbanization are the key factors responsible for leading positions of Europe and Asia-Pacific in the global biological wastewater treatment market.
