Automated Tubular Backwash Filtration: A Smarter Approach to Industrial Water Management

Industrial facilities are under growing pressure to reduce water consumption, control wastewater costs, minimize maintenance, and improve process reliability. SIGMA Design Company’s Automated Tubular Backwash Filter Systems provide an engineered approach to these challenges by combining filtration, automation, solids concentration, and water recovery into one integrated solution.

Unlike traditional bag and cartridge filters that rely on disposable media, SIGMA’s tubular filtration systems automatically backwash to remove accumulated solids while maintaining the filtration process. The result is clean water that can be reused or returned to the process, along with a concentrated solids stream that can be directed to or integrated into existing solids-handling equipment.

SIGMA Design Company’s Automated Tubular Backwash Filter Systems provide continuous, automated filtration for demanding industrial water applications designed for process water, water reuse, cooling water, and solids concentration, the system removes suspended solids while reducing reliance on disposable filter media.

SIGMA’s systems can be customized to meet specific flow, filtration, footprint, and controls

requirements. Applications include cooling tower side stream filtration, heat exchanger and spray nozzle protection, food processing wash-water reuse, plastics recycling wash water, and pretreatment for membrane and DAF systems.

What sets SIGMA apart is our engineering-led, turnkey approach. Rather than simply supplying a filter, SIGMA can design and manufacture complete skid-mounted systems with PLC/HMI controls, multiple filter configurations, solids dewatering integration, and water recovery. With in-house engineering and manufacturing support, customers gain a single partner capable of designing, building, testing, and supporting the complete system.

SIGMA Automated Tubular Backwash Filter Systems provide an intelligent alternative between standard catalog filters and costly custom-engineered filtration projects— helping industrial facilities recover more water, manage solids more effectively, reduce consumables, and improve overall process efficiency.
