Our Two-Step Reverse Osmosis™ (TSRO) System
The TSRO System is comprised of a “Stack” of proprietary membranes that work together with traditional spiral reverse osmosis (RO) membranes to concentrate wastewaters and reclaim high-quality clean water.
Raw wastewater or ultrafilter permeate is first passed through the stack membranes, where 50-95% of the water is removed by passing through the membrane and into a salt water solution. The salt water is then processed by RO membranes to generate clean water and brine. The brine is passed back through the stack continuously and the clean water is discharged or reused onsite.
Compared to RO alone, this system provides significant advantages because the Stack can handle high solids, has a very low tendency to foul, and uses very little energy because the wastewater is pumped through it relatively slowly and at low pressures. By isolating the RO membranes from the wastewater, we can produce very clean effluent, reduce downtime for cleaning, and extend the life of the elements.
Compared to an ultrafiltration system, the TSRO produces substantially cleaner effluent that will look like clear water and have much lower levels of all contaminants. Because both the membranes in the Stack and the RO have >95% rejection of ammonia and organics, the water effluent is very clean.
This technology is patent-pending and Digested Organics is the first to bring it to the wastewater treatment industry. Call today to learn more about how this can be used at your facility to reclaim water, produce value-added concentrates, and reduce disposal costs.
