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 the membrane If the membrane is damaged, it can be replaced to restore the performance of the membrane assembly.

3. Regular cleaning
During the operation of the DTRO membrane assembly, contamination is inevitable, so it needs 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 is soaked. 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.
