Market Overview and Growth Outlook

The biological wastewater treatment market is expected to grow from USD 9.48 billion in 2022 to USD 12.72 billion by 2028. The biological wastewater treatment market is expected to grow at a CAGR of 5.02% during the 2023-2028 forecast period. The expansion is tied to population growth, industrialization, regulatory requirements, and ageing treatment infrastructure.

The biological wastewater treatment market growth outlook is shaped by a direct relationship between wastewater generation and treatment requirements. Growing industrialization produces wastewater that must be treated to avoid environmental pollution, while population growth places additional pressure on water resources and wastewater treatment infrastructure.

Regulatory requirements add another demand layer. Governments are implementing stringent rules for wastewater treatment and discharge, creating requirements for technologies capable of meeting required effluent quality standards. The source identifies biological wastewater treatment among the advanced treatment technologies needed for these requirements.
