4DS™ Technology

Superior Technology for Recovering Dissolved Metals

We set out to develop an industrial-scale technology for the selective recovery of dissolved metals and nutrients. Today, its recovery performance is proven at flow rates of 50 m3/h, and the first industrial-scale water treatment system built entirely on 4DS™ has operated stably and reliably for over a year.

4DS™ Technology Platform

Thanks to its customizable, modular design, the same technology platform can be adapted to a wide range of industrial challenges:

⛏ VALUE RECOVERY

Turns low-value and hazardous waste streams into a source of revenue by recovering valuable metals and nutrients. Payback times can be under 3 years.

📈 PROCESS OPTIMIZATION

Removes up to 99% of dissolved impurities from process liquids, down to ppb levels. The result is better process performance and higher product quality.

💧 COMPLIANCE & COST OPTIMIZATION

By selectively targeting hazardous metals, it helps meet even the strictest discharge limits and cuts waste by up to 90%.

MANUFACTURING METHOD

Adding a Fourth Dimension with 3D Printing

We use selective laser sintering (SLS) to produce chemically functional 4DS™ units. This unique method allows almost limitless optimization of chemical and physical properties, making it possible to recover more than 20 different ions.

4DS™ units combine small particle size with a porous structure to maximize chemical performance. The small particles provide a larger surface area and faster kinetics, while the uniformly porous structure lets water flow through easily and reach the active material better.

Optimized Recovery Process

The cyclic 4DS™ process extracts the target metals and nutrients from water while other ions flow through. Once the capacity is full, the unit is washed with dilute acid or base and the process starts over.

The unique structure gives 4DS™ technology higher selectivity and greater capacity for target ions. In practice, this means:

  • No complex sludge. You get a high-quality concentrate instead which can be reused or refined further.
  • Compact equipment. As capacity is not wasted on low-value material, you can do more with the same amount of media.
  • Less chemicals. The washing process requires less chemicals and rinse water to regenerate the units.

BENEFITS

Recover Value Where Others Can’t

Conventional methods such as SX-EW, ion exchange, membranes and precipitation struggle with complex wastewater, especially when a low-concentration target metal is mixed with high concentrations of competing ions. They also tend to require large amounts of chemicals and extensive infrastructure.

4DS™ performs where others fall short. It turns challenging waste streams into savings and revenue by lowering operating costs and enabling water and metals to be reused. As a result, sustainable water treatment and the recovery of dissolved materials become economically viable for a wide range of new processes.

Due to selectivity, the recovery efficiency remains higher even in longer cycles compared to ion exchange.
