Engineered Innovation in SX Filtration

Our SX filtration systems are engineered as fully integrated solutions—reducing risk, simplifying operations, and delivering long-term performance in demanding mining environments.

Simplified Deployment

Modular shipping and installation packages reduce site complexity, accelerate commissioning, and minimize construction risk.

Automated Operation & Visibility

Advanced automation, S&L RemoteView™, and intuitive inspection points simplify O&M while improving uptime and operator confidence.

Future-Ready Filtration

Modern instrumentation, standardized platforms, and automated piping and valve skids reduce project risk while keeping systems aligned with evolving technology.

DI-SEP® SX System Components

  • Access: Provides safe entry for inspection, maintenance, and cleaning.
  • Organic Discharge: Efficiently removes accumulated organic material from the system.
  • Inlet Connection: Introduces electrolyte evenly into the filter vessel.
  • Inlet Distributor: Ensures uniform flow across the filter media for consistent filtration.
  • Dual Media: Anthracite on top and garnet on bottom; removes fine particulates while maintaining layer stability.
  • Air Scour Distributors: Loosen trapped solids in the media during backwashing for thorough cleaning.
  • Outlet Distributors: Collect filtrate while preventing media carryover.
  • Filtrate: Clean, high-purity electrolyte ready for recovery or further processing.

DI-SEP SX Filtration FAQs

The DI-SEP SX filtration system is designed to remove fine solids, sand, and other heavy particulate matter from wastewater and stormwater streams. It uses a combination of vortex separation and sedimentation to ensure high-efficiency removal while minimizing maintenance needs.

Efficient removal of grit and solids protects downstream equipment such as pumps, clarifiers, and aeration systems. This reduces wear, prevents clogging, and improves overall plant performance and longevity.

The system is capable of removing a wide range of heavy inorganic solids, including sand, gravel, cinder, and other particulate matter typically in the range of 75–300 microns, depending on system configuration.

DI-SEP SX offers higher removal efficiency across a wider range of particle sizes than conventional systems. Its design allows for continuous operation under variable flow conditions without sacrificing performance, unlike traditional basins or channels which may lose efficiency at peak flows.

Maintenance is minimal and typically involves periodic inspection and removal of collected solids. The system's design reduces wear on mechanical components and prevents buildup that could impede performance.

Yes. DI-SEP SX is designed to be flexible and can often be installed in existing facilities with minimal modifications to piping or basins. Custom configurations are available depending on site-specific requirements.

Advanced DI-SEP SX systems can achieve up to 95% removal efficiency for solids down to 75 microns, maintaining high performance across all flow conditions.

Maintain Spare Parts to Optimize SX Performance

Like any process equipment in corrosive environments, the key to maintaining optimal DI-SEP® SX Filter performance over time is maintaining an essential parts inventory and media supply. Taking a proactive approach as recommended by your O&M Manual significantly reduces operational downtime, essentially providing inexpensive insurance against lost production time.
