Applications
Every water source presents unique challenges — from surface water with seasonal variability to groundwater with iron and manganese, or membranes that demand precise pretreatment. Roberts Filter Group designs and supports filtration solutions that help municipalities and industries meet regulations, protect public health, and run reliably for decades. Explore the applications below to see how we can solve your water treatment challenges.
Drinking Water Treatment (Surface Water Sources)
Roberts Filter Group helps municipalities deliver safe drinking water by removing turbidity, sediment, algae, and organics from lakes and rivers. Our gravity filters, underdrains, wash systems, and media are designed to handle seasonal variability and provide consistent, compliant performance.
Key Benefits: Regulatory compliance, stable operation, long-term performance.
Groundwater Treatment
For communities relying on wells, Roberts pressure filters provide reliable removal of iron, manganese, arsenic, hardness, and sediment. Our systems are compact, robust, and easy to maintain — ensuring safe drinking water from groundwater sources.
Key Benefits: High removal efficiency, compact footprint, reduced scaling.
Membrane Pretreatment (Desalination & RO Systems)
Membranes require excellent pretreatment to operate effectively. Roberts clarifiers, plate settlers, and multimedia filters remove suspended solids, colloids, and silt — ensuring consistent turbidity and protecting RO membranes from fouling and scaling.
Key Benefits: Longer membrane life, reduced cleaning frequency, stable operations.
Industrial Process Water
Industries rely on consistent water quality for boilers, cooling towers, and production. Roberts provides filtration systems that remove suspended solids, particulates, and organics, ensuring reliable process performance across sectors like power, manufacturing, and food & beverage.
Key Benefits: Protects equipment, lowers operational costs, ensures consistent process quality.
Wastewater Tertiary Filtration / Effluent Polishing
Roberts tertiary filtration systems polish secondary effluent to meet reuse and discharge standards. Our filters reduce BOD, TSS, and pathogens, preparing water for irrigation, industrial reuse, or safe environmental release.
Key Benefits: Regulatory compliance, water reuse potential, enhanced effluent quality.
Retrofitting / Upgrading Existing Filters
Roberts specializes in extending the life of existing filter infrastructure. We upgrade underdrains, add air scour or wash systems, integrate new instrumentation, and replace media — improving efficiency without costly new construction.
Key Benefits: Cost savings, extended lifespan, improved efficiency.
Filter Maintenance & Lifecycle Management
From routine inspections to predictive maintenance, Roberts provides services that ensure long-term reliability. Our audits, media tracking, and optimization programs keep your system running efficiently and reduce total lifecycle cost.
Key Benefits: Lower operating costs, reduced downtime, proactive support.
Specialty Contaminant Removal
Emerging contaminants require advanced solutions. Roberts offers filtration systems with specialized media — including activated carbon and blends — for the removal of PFAS, heavy metals, microplastics, and pharmaceuticals.
Key Benefits: Compliance with emerging regulations, adaptable solutions, safe water supply.
