Major companies operating in the wastewater treatment services market are concentrating on the development of innovative solutions, such as modular water and wastewater treatment systems, to improve operational efficiency, enhance treatment performance, and support sustainable, regulation-compliant wastewater management. Modular water and wastewater treatment systems integrate physical, chemical, and biological processes to eliminate impurities, pathogens, solids, chemicals, organic matter, and pollutants from water and wastewater streams. For instance, in May 2024, Synagro Technologies Inc., a U.S.-based wastewater and biosolids solutions provider, introduced the SynaPure Water and Wastewater Treatment System. This modular, single-pass, membrane-based solution can be skid-mounted or containerized for rapid deployment, configured for temporary or permanent operations, and interconnected to manage higher treatment capacities. The system treats complex influent streams, including landfill leachate, industrial effluents, and lagoon wastewater, removing both conventional contaminants (COD, dissolved and suspended solids, nutrients, and metals) and persistent or emerging contaminants such as PFAS, producing discharge-grade or reuse-quality water. SynaPure delivers up to 98% contaminant removal, requires approximately 90% less space, and offers up to 60% overall cost savings compared with traditional wastewater treatment systems.
