The treatment effect of the disc-tube reverse osmosis DTRO system does not depend on the pretreatment process. The open flow channel can treat wastewater containing more colloids and suspended solids. The membrane component has a short flow path and a wide flow channel. The special hydraulic conditions make the liquid form turbulence in the membrane column, which greatly reduces the scaling, pollution and concentration polarization of the membrane surface.

Daily maintenance precautions for DTRO membranes:

1. Regularly check the water quality of landfill leachate

The water quality of landfill leachate fluctuates greatly, and the raw water quality needs to be regularly analyzed and checked during the treatment process

2. Regularly check the water quality of the single membrane module

DTRO membrane modules are all in parallel mode. During normal operation, the conductivity of the produced water generally does not change much. If the conductivity of the produced water is found to increase during operation, the conductivity of the produced water of the single membrane module can be checked. If the conductivity is higher than the conductivity of the discharge, the single membrane module can be isolated and disassembled for inspection. Generally, the O-ring is detached or If the membrane is damaged, the performance of the membrane assembly can be restored after replacement

3. Regular cleaning

DTRO membrane assemblies will inevitably be contaminated during operation, so they need to be cleaned. The cleaning method is generally chemical cleaning. The DTRO membrane cleaning agent can be used for online cleaning to restore the flux. During the cleaning process, the temperature is generally controlled at 35°C, and the cycle soaking is carried out. The chemical cleaning time is generally 2 hours. If the contamination is particularly serious, the cleaning time can be appropriately extended. The cleaning process is a professional maintenance process, and the operator needs to strictly follow the cleaning operation procedures to ensure the service life of the membrane assembly.
