CLEAN RO and CLEAN RO-1 antiscalants
Phosphonate-based scale inhibitors for reverse osmosis and nanofiltration systems. Made in Tashkent by ONSITE.
CLEAN RO and CLEAN RO-1 are antiscalants made by ONSITE (Tashkent, Uzbekistan) from organic complexones for reverse osmosis, nanofiltration and ultrafiltration. They inhibit carbonate and sulfate scale at 3–10 mg/L (typically 5 g/t). Packed in 25 kg, 240 kg and 1300 kg; 36-month shelf life.
Two products, one job: clean membranes
