Disk tube reverse osmosis membrane technology for landfill leachate engineering

Disk tube reverse osmosis membrane technology for landfill leachate engineeringDTRO disc tube reverse osmosis membrane is a membrane product that can achieve high concentration (high salt, high organic matter, etc.) liquid treatment, recovery, standard discharge, and achieve wastewater concentration and reduction. It is a form of reverse osmosis.

Disk tube reverse osmosis membrane technology for landfill leachate engineeringDTRO disc tube reverse osmosis membrane supply, DTRO (disc tube reverse osmosis membrane system) technology is a membrane separation technology driven by pressure. Its basic principle is to use pressure difference as the driving force, apply pressure exceeding the solution osmotic pressure to the semi permeable membrane, and permeate the water pressure in the concentrated solution to the dilute solution side of the membrane, while the concentrated solution continuously concentrates on the other side of the membrane, achieving the purpose of solute and water separation. The main separation function in reverse osmosis asymmetric membranes is the tightly arranged surface dense layer of polymers, which can remove almost all impurities in water, including various inorganic salts, molecules, organic colloids, bacteria, viruses, heat sources, etc., through the sieving effect of substances and the filtering effect of solute solvent membrane surface polymers.

The process stage where DTRO products are located is generally the concentration and reduction stage of high salt and high organic wastewater. Its front-end treatment process may include flocculation, sedimentation (air flotation), sand filtration, ultrafiltration (softening), reverse osmosis, etc., while the back-end treatment process is generally evaporation, etc.

• High pressure resistance: 75~160bar

• High SDI resistance: (SDI pollution index)<15

• 耐高 COD :1000~20000mg/L

• High TDS resistance: 2000~80000 mg/L

• Convex point wide channel:

The guide plate adopts convex points and turbulence optimization design, and the open flow channel increases the surface flow velocity (Reynolds coefficient ≥ 5000, 3-5 times that of the rolled film) to avoid solid matter from being trapped on the surface, and has self-cleaning function. Effectively reduce concentration polarization.

• Octagonal structure membrane package:

During high-pressure operation, the octagonal structure design results in uneven acceptance points, which will generate high-frequency vibrations under the impact of water flow, driving the water flow to form a 'S' flow direction and continuously scouring, avoiding pollution and scaling.
