Filtration/Tertiary treatment solutions

ANDRITZ tertiary treatment solutions provide the final polishing step needed to meet today’s strict discharge limits and water reuse requirements. As primary and secondary treatment alone are no longer sufficient to reliably remove phosphorus, suspended solids, and remaining pollutants, advanced filtration becomes the critical final barrier to ensure compliance and high effluent quality. ANDRITZ systems are designed to boost plant performance by reducing the load on downstream processes, minimizing energy and chemical consumption, and delivering stable, high-quality treatment results.
The portfolio includes gravity underdrain filters, continuous sand filtration, high-capacity disc filters, and mobile filtration units for flexible or temporary needs. These technologies are engineered for energy efficiency, durability, and straightforward integration into existing facilities. Whether for municipal plants or industrial sites with limited space, ANDRITZ solutions offer reliable solids removal and consistent filtration performance with minimal maintenance and low operational effort. In modern wastewater treatment, tertiary filtration is where sustainability, compliance, and long-term operational reliability come together.
