The biological wastewater treatment market has seen considerable growth due to a variety of factors.
• Over the recent years, the biological wastewater treatment market has experienced substantial growth. The market is projected to increase from $11.32 billion in 2024 to $12 billion in 2025, reflecting a compound annual growth rate (CAGR) of 6.0%. The past growth can be linked to factors such as industrial growth and reduction in effluent discharge, an increase in public awareness about water pollution, the economical advantages of biological treatment, and emphasis on water reusability and recycling. Other contributing factors include population growth and urban development.
The Biological Wastewater Treatment market is expected to maintain its strong growth trajectory in upcoming years.
• Predictions for the biological wastewater treatment market indicate a robust growth in the coming years, with an estimate to reach $16.31 billion by 2029, exhibiting a compound annual growth rate (CAGR) of 8.0%.
Factors poised to contribute to this escalation during the forecasted period include the increase in infrastructure upgrade investments, a rise in the usage of decentralized treatment structures, emphasis on water recycling and resource recuperation, rigorous environmental norms along with an upsurge in industrial and municipal wastewater volumes. In the same forecasted span, the market is expected to witness trends such as collaborations for innovative solutions, the rise of principles of the circular economy, optimization and recovery of energy and resources, a focus on microbial ecology and bioaugmentation, and the adoption of nature-inspired solutions.
The escalation in water pollution along with a decline in water quality is anticipated to stimulate the expansion of the biological wastewater treatment market. Water pollution entails the discharge of materials into groundwater beneath the surface or bodies of water like lakes, streams, rivers, estuaries, and oceans, to such an extent where these materials disrupt the advantageous use of the water. Biological wastewater treatment utilizes the natural mechanism of microbial decomposition for removing pollutants in wastewater and other undesirable elements. For example, reports from the UK's Environment Agency in July 2024 verified that there were 1,658 instances of sewerage pollution in 2022, a figure that rose to 1,902 in 2023. Consequently, due to increased industrialization, the biological wastewater treatment market is seeing substantial growth.

Advancements in technology are proving to be a significant trend in the biological wastewater treatment industry. Leading figures in this market are prioritizing the innovation of new technologies to enhance biological wastewater treatment's efficiency, ensuring they maintain their market position. Evonik, a specialty chemical company from Germany, unveiled SEPURAN membrane technology in April 2022, an inventive method devised to augment biological wastewater treatment's effectiveness through precise oxygenation of microorganisms that control significant material conversion reactions. Evonik's SEPURAN membrane technology is designed to intentionally infuse bacteria with oxygen, in addition to nitrogen, another atmospheric gas; this could be delivered to the upstream solids separation to prevent microorganism growth. Thus, the organisms can absorb more nutrients from the pre-treatment process.
