Biological Wastewater Treatment Market Report 2025

The biological wastewater treatment market size has grown strongly in recent years. It will grow from $11.32 billion in 2024 to $12 billion in 2025 at a compound annual growth rate (CAGR) of 6%. The growth in the historic period can be attributed to industrial expansion and effluent discharge reduction, public awareness and concern for water pollution, cost-effectiveness of biological treatment, focus on water reuse and recycling, population growth and urbanization.

The biological wastewater treatment market size is expected to see strong growth in the next few years. It will grow to $16.31 billion in 2029 at a compound annual growth rate (CAGR) of 8%. The growth in the forecast period can be attributed to increasing investment in infrastructure upgrades, growing adoption of decentralized treatment systems, focus on water reuse and resource recovery, stringent environmental regulations, rise in industrial and municipal wastewater volumes. Major trends in the forecast period include collaboration for innovation, emergence of circular economy principles, energy recovery and resource optimization, focus on microbial ecology and bioaugmentation, adoption of nature-based solutions.

The increasing issue of water pollution and the decline in water quality are anticipated to drive the growth of the biological wastewater treatment market in the coming years. Water pollution refers to the introduction of substances into subsurface groundwater or bodies of water such as lakes, streams, rivers, estuaries, and oceans to the extent that these substances disrupt the beneficial use of the water. Biological wastewater treatment systems harness the natural process of microbial decomposition to break down pollutants in wastewater and remove other undesirable components. For example, in July 2024, reports from the Environment Agency, a UK government body, indicated that there were 1,658 sewerage pollution incidents in 2022, which rose to 1,902 in 2023. Consequently, the biological wastewater treatment market is growing due to increased industrialization.

The rise in water-borne diseases is expected to boost the growth of the biological wastewater treatment market in the future. Water-borne diseases are illnesses caused by pathogenic microorganisms, including bacteria, viruses, parasites, and fungi, that spread through contaminated water. Biological wastewater treatment is essential for preventing these diseases by effectively removing contaminants, promoting environmental sustainability, and ensuring compliance with regulatory standards. For example, an October 2022 article in News Medical Life Sciences reported that at least 2 billion people rely on drinking water sources contaminated with feces. These contaminated sources can transmit water-borne diseases, which are responsible for approximately 502,000 diarrheal deaths each year. Therefore, the increasing prevalence of water-borne diseases is driving the growth of the biological wastewater treatment market.

Technological advancements are steering the biological wastewater treatment market's evolution, with industry leaders focusing on innovation to enhance treatment efficiency. In April 2022, Evonik, a Germany-based chamical company introduced SEPURAN membrane technology, a groundbreaking approach to oxygenate microorganisms precisely during wastewater treatment. This innovation elevates material conversion reactions and optimizes nutrient absorption. The industry's commitment to technological advancements underscores its dedication to sustainable solutions and regulatory adherence.

Major players in the biological wastewater treatment market are strategically introducing innovative products to bolster revenue streams. The launch of BioGill's Max Series in July 2023 exemplifies this trend. The Max Series, including units like Max 2, 4, and 6, features advanced designs and materials, offering superior efficiency, reliability, and longevity. These units minimize maintenance expenses and downtime, aligning with the market's focus on delivering cost-effective and efficient wastewater treatment solutions.

In September 2024, Axius Water, a US-based provider of water quality management services focused on improving the effectiveness of water and wastewater treatment, acquired MITA Water Technologies for an undisclosed amount. This acquisition aims to bolster Axius's mission of addressing nutrient pollution in wastewater management. MITA Water Technologies is an Italian company that specializes in designing, manufacturing, and marketing equipment for the purification and filtration of both municipal and industrial wastewater.

Biological wastewater treatment is a method designed to leverage microorganisms for the digestion of dissolved contaminants in effluents. These microorganisms utilize the contaminants for their own sustenance and reproduction.

The primary processes employed in biological wastewater treatment are aerobic and anaerobic. The aerobic process relies on activities that require air or oxygen, contrasting with anaerobic activities that occur without the need for oxygen. Sales channels for this technology encompass direct channels and distribution channels, catering to various end-user industries, including municipal and industrial sectors.
