Download Sample   Reports Overview

The Global Biological Wastewater Treatment Market Size is predicted to be valued at $15,067.7 million by 2031, surging from $9,120.0 million in 2021, at a noteworthy CAGR of 5.2%.

Impact Analysis of COVID-19 on the Biological Wastewater Treatment Market

The COVID-19 outbreak has disrupted the global economy by halting the processes of several industries. The World Health Organization determined that washing hands with soap and water is a simple procedure for combating coronavirus. However, research has shown that nearly 3 billion people lack access to safe drinking water. As a result, people are particularly vulnerable to the potentially fatal virus. As a result, countries are focusing more on providing clean water. Decentralized treatment can satisfy the biological wastewater treatment market share goals during this epidemic since it is an affordable, low-maintenance approach that is sustainable both environmentally and economically. One prospective study field of major significance at the moment is the creation of small-scale treatment infrastructure as an alternative to centralized sewer systems for hotspots such as hospitals, clinics, and quarantine facilities that are producing probable coronavirus-contaminated wastewater. Hospitals or other healthcare facilities without access to a full WTP may employ a decentralized treatment unit and disinfect wastewater according to industry standards before releasing it into the environment.

However, several initiatives launched by Ecolab Inc. are helping society recover from pandemic. For instance, Ecolab Inc., a leader in hygiene, water, and infection prevention solutions and services, announced in June 2021 that a 9% to 15% price increase will be implemented to the company's industrial segment products, effective immediately or as contracts permit, due to rising energy and raw material prices, limited raw material availability, and rising transportation, packaging, utility, and labor costs.

Global Biological Wastewater Treatment Market Analysis

The rise in industrialization and increased need for water are predicted to be the primary driving factors in the biological wastewater market growth. Many companies require significant amounts of water for day-to-day operations; thus, with the aid of biological wastewater treatment market demand, the industries may 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 share. Additionally, physical and chemical treatments have proven effective for industrial users. Metal finishers have effectively removed heavy metals such as chromium, nickel, zinc, lead, and cadmium using these techniques. These technologies have played a significant role in helping our environment to progress through the early days of the industrial revolution, when rivers were on fire, odors were revolting, and people could not drink the water safely. These systems will continue to play an important part in all metal finishing enterprises across the world.

According to predictions, market expansion will be hampered globally due to the high cost of wastewater treatment. The main obstacles to the expansion of the industry are high setup costs, expensive installation, and complicated setup. Additionally, operational costs and sludge transfer charges add to the cost of wastewater treatment, inhibiting market expansion. Additionally, the absence of research and development efforts in this industry limits its expansion globally.

The demand for high-quality wastewater treatment systems is growing, as are ways to decrease energy usage and boost capacity in current plant footprints. Evoqua can adapt to changing wastewater treatment requirements with solutions such as biological oxygen demand (BOD) reduction, aeration, clarifying, phosphorus removal, and nitrogen removal. They provide essential improvements for simultaneous nitrification and denitrification, magnetite ballasted treatment, and nutrient removal. Furthermore, as plant treatment equipment reaches the end of its useful life, Evoqua can assist in converting what you have into what you need, increasing performance, reducing maintenance, and extending lifetime to keep treatment facilities operational. The biological wastewater treatment is employed because it offers increased performance, water reuse, and energy savings.

Global Biological Wastewater Treatment Market, Segmentation

The global biological wastewater treatment market is segmented based on process, type, and region.


The process segment is further classified into aerobic, anaerobic, and anoxic. Among these, the aerobic sub-segment accounted for a highest market share in 2021. Anaerobic treatment makes use of bacteria to hasten the decomposition of biological material in an oxygen-free setting. Anaerobic procedures can be employed in lagoons and septic tanks, but the most well-known anaerobic treatment is anaerobic digestion, which is used to treat agricultural waste, municipal wastewater, chemical effluent, and effluent from the manufacturing of food and beverages. One of the most active areas of resource recovery is energy recovery, which is powered by anaerobic digestion. This process of energy recovery, commonly referred to as "waste-to-energy," uses anaerobic digestion to create biogas, which is mostly made of methane. It can be used by operators to generate energy to help power operations as they transition to becoming energy net zero, or even to convert waste streams into revenue streams.


The type segment is further classified into municipal waste and industrial waste. Among these, the industrial waste sub-segment accounted for a highest market share in 2021. Industrial waste occurs in a variety of forms, including cafeteria waste, masonry and concrete, scrap metals, chemicals, weed grass and trees, timber and scrap lumber, and other wastes of a similar nature. Hazardous and non-hazardous wastes are divided into categories in industrial solid waste. Industrial solid waste may be contained as a solid, liquid, or gas. Hazardous waste can be generated during manufacturing and other industrial processes. Paints, insecticides, and cleaning fluids are just a few examples of industrial waste that can include a variety of items that are thrown away by businesses or individuals. Any waste that does not meet the Environmental Protection Agency (EPA's) definition of hazardous waste and does not qualify as municipal waste is considered non-hazardous industrial waste.


The biological wastewater treatment market analysis in Asia-Pacific is projected to show the fastest growth. The rise in population, growing energy security, and rising environmental concerns such as greenhouse gas emissions are some of the major factors driving the growth of the Asia-Pacific biological treatment market. The rapid urbanization and population growth, the increase in demand for residential water treatment technology, the development of membrane technology, the deterioration of the environment, the scarcity of water resources, and the rise in number of investments in water infrastructure by public sector organizations in the region are all factors that have contributed to the high market growth in Asia-Pacific.
