What is DTRO?
DTRO Disc-tube Reverse Osmosis Membrane-High Pressure Concentration of High Salt Wastewater
Working Principal of DTRO
DTRO disc-tube reverse osmosis membrane is a membrane product which can realize high concentration (high salt, high organic matter, etc.) feed liquid treatment, recovery, up-to-standard discharge and wastewater concentration and reduction. It is a form of reverse osmosis.
DTRO membrane column is formed by stacking reverse osmosis membrane and guide plate together, fixing them through central tie rod and end plate, and then putting them into pressure-resistant membrane shell. Its main components include: bearing nut, water producing connector, water inlet and outlet connector, upper and lower bearing flanges, upper and lower water passing flanges, membrane shell, center rod, guide plate, membrane bag, etc.
DTRO advantages
High pressure resistance: 75~160bar
High SDI tolerance: (SDI pollution index) < 15
High cod tolerance: 1000 ~ 20000 mg/l
High TDS :2000~80000mg/L mg/L.
Low cost
★ Convenient cleaning and good recovery of performance parameters.
★ The membrane module has long service life.
Strong adaptability
- High-pressure equipment, the recovery rate is as high as 90%.
- Stable water production, with a single set of treatment capacity of 5 ~ 100m3/h
