Specialty — High-Pressure Concentration
SP-DT (Disc-Tube) Series
Disc-tube modules for landfill leachate and extreme wastewater
Product description
The SP-DT series membranes are SV-NanoMetrix's flagship solution for the most extreme wastewater treatment challenges. Leveraging disc-tube modular technology, these modules deliver performance across TDS concentration up to 70,000 ppm, landfill leachate treatment and industrial resource recovery, thriving in harsh, high-fouling and ultra-high-salinity conditions where conventional membranes fall short.

Performance figures are nominal values obtained under the standard test conditions stated with each table. Actual performance varies with feedwater chemistry, pretreatment, flux, recovery, temperature, pressure and operating practice. Individual element flow may vary from the nominal value. Specifications are subject to change without notice — request the current datasheet before specifying.
