FlexEDR can treat saline agricultural wastewater for reuse: preserve ions of value (calcium) while removing the pollutants (sodium).
FlexEDR can bolt-on to existing reverse osmosis (RO) plants; increasing recovery and plant reliability.
View case studies from a selection of our past projects. Saltworks’ ion selective membranes can recycle fertilizer inputs.
We have successfully treated some of the most difficult wastewaters. These projects treated various waste streams to meet discharge regulations, reuse requirements or selective ion recoveries.
ScaleSense
Real-Time Sensor
An automated, real-time sensor for saline waters that measures calcium (Ca2+), barium (Ba2+), sulfate (SO42-) ions and silica (SiO2). ScaleSense is robust and corrosion-resistant and functions accurately and precisely, even at extremely high-TDS.More …
XtremeRO/NF Brine
Concentrator
Next-generation water-maker and brine-concentrator based on reverse osmosis that achieves extreme freshwater recoveries, enabling cost-effective brine management and treatment of challenging organic-laden waters including oil & gas produced waters.
XtremeUF
Ultrafiltration System
An ultra-robust ceramic based ultrafilter that can remove suspended solids, oils, and grease from the most challenging slurries and impacted wastewaters. XtremeUF cleans itself as it operates, to ensure your membranes maintain performance.
SaltMaker
AirBreather
The first evaporator-crystallizer with no atmospheric contact, important for water with volatile organics. Choose between no liquid water return or clean water that is safe for discharge.
This article introduces a new type of ceramic membrane system and explains how it opens the application range. An example of treatment of oil and grease in produced water is provided.
New ultra-high pressure reverse osmosis technology for minimal liquid discharge (MLD) can reduce brine management costs by three times relative to evaporators. Modernized chemical softening technology is available to prevent scaling and enable recovery up to the osmotic pressure limit at 1,200 or 1,740 psi.
As regulations on FGD wastewater tighten, additional treatment is required. Often, this is chemically intense, and high cost. The best means to lower treatment costs is to reduce the volume of wastewater generated, usually by increasing internal recycle.
The many options for managing brine, a term for saline wastewater from industrial processes, fall under two categories: brine treatment and brine disposal. Brine treatment involves desalinating the brine for reuse and producing a concentrated brine (lower liquid waste volume), or residual solids (zero liquid discharge).
