Mobile Disc Filtration

Q: How much backwash water does SuperDisc use?

Backwash water usage averages 3.51-4.86 percent of filtered flow, making SuperDisc highly efficient. Most competing sand filters require significantly higher backwash volumes, increasing water waste and operating costs. Our partially submerged design allows continuous filtration during the backwash cycle, reducing idle time and boosting net throughput.

Q: Can SuperDisc operate continuously during backwash?

Yes. Our partially submerged design allows continuous filtration during the backwash cycle. While the oscillating arm cleans one section of discs, the remaining discs continue filtering incoming water. This design minimizes downtime, maintains stable flow rates, and maximizes throughput – your operation stays productive without idle periods.

Efficient, Compact, and Low Energy Solution for Superior Liquid-Solids Separation

Mobile disc filters provide a high-rate filtration process in a compact footprint that requires less backwash than other filtration systems. Each disc houses a polyester filter mesh used for liquid-solids separation in many applications. The mobile disc filter units are low-energy systems with automatic self-generating backwash and remove suspended solids and precipitated metals larger than 10µm.

Our mobile disc filtration units are fully integral units that require minimal assembly without the need for mounting and alignment of other ancillary equipment. They are available for rapid deployment and setup.

Use Cases

Mobile disc filtration delivers high-rate liquid-solids separation in a compact, low-energy footprint that operates continuously – even during cleaning cycles. SuperDisc™ integrates all components into one transportable unit, requiring minimal assembly and supporting rapid deployment. The inside-out filtration design with pressurized backwash doubles filter media life while reducing water waste. These capabilities make SuperDisc ideal for municipal wastewater treatment, industrial process water, mining operations, and emergency water supply scenarios.

Frequently Asked Questions

What is mobile disc filtration and how does it work?

Mobile disc filtration is a high-rate liquid-solids separation process using polyester filter mesh discs in a compact, transportable unit. Inside-out filtration design pushes water through the mesh from the center outward. An oscillating backwash arm sprays pressurized water to clean the discs without mechanical scraping, doubling filter media usable life. We integrate all components – discs, backwash system, motors, controls – into one unit requiring minimal assembly and setup.

What suspended solids and impurities can SuperDisc remove?

SuperDisc removes suspended solids and precipitated metals larger than 10 microns (µm). The polyester filter mesh achieves nominal pore size of 10 µm, capturing organic matter, sand, sediment, and other solid particles from water. We use inside-out filtration – water flows from disc center outward through the mesh – ensuring efficient capture without mechanical damage to filter media.

How much backwash water does SuperDisc use?

What is the maximum flow rate for a mobile disc filtration unit?

Each SuperDisc unit operates at a maximum design flow of 2,000 gallons per minute (gpm) with a design filtration rate of 5 gpm per square foot (ft²). The unit contains 10 installed discs providing 463 square feet of submerged surface area. We size units based on your water quality and flow requirements, ensuring proper retention time and filtration performance.

How does phosphorus removal work with SuperDisc?

We remove dissolved phosphorus by chemical conditioning before filtration. Ferric chloride (22-28 mg/L) precipitates dissolved phosphorus into solid particles. Cationic polymer (0.28-0.36 mg/L) enhances floc formation and settling. SuperDisc then captures the precipitated phosphorus solids, achieving 88-93 percent total phosphorus removal in effluent polishing applications – producing clean water meeting strict discharge standards.

Can SuperDisc operate continuously during backwash?

What does “minimal head loss” mean for operating costs?

Head loss is the pressure drop across the filter as water flows through the mesh. Minimal head loss means our system requires less pumping energy to push water through the discs. SuperDisc achieves this through large surface area (463 ft²) and inside-out filtration design. Lower energy demand reduces power consumption and extends pump life – cutting your overall operating expenses.

Why choose SuperDisc over sand filters for water filtration?

Sand filters require larger footprints, deeper foundations, and higher backwash volumes (often 5-15% of flow versus our 3.51-4.86%). SuperDisc offers compact design, lower water waste, and faster flow rates (5 gpm/ft² design rate). Our inside-out filtration and non-mechanical backwash extend filter media life. We also deliver faster installation and lower capital requirements.
