Bio-toilet (DMBR)

Features and Advantages of the Low Pressure, Ultra Filtration Bio-Toilet (DMBR)’s system:

-

DMBR’s high concentration of mixed liquor suspended solids (MLSS) improves the efficiency, reducing the treatment time, hence suitable for limited space available

-

All wastewater is treated in the same DMBR unit, hence reducing space required and cost
- Nano filtration is used to reduce space compare to traditional sedimentation method
- Simple structure, fully automated with PLC control
- Text alert and online reminders for each DMBR system’s status
- Based on client’s requirement, various pre-treatment equipment can be installed to DMBR
- Options to add UV light and chlorine system to meet the reuse or discharge standard

Target Requirement
Within 2015-2017, there will be a total supply of 57,000 toilets (33,000 newly built & 24,000 retrofitted) installed at tourism areas in China, delivering the standards of sufficient, clean & odorless, free & practical and effectively managed.

 
China's 3-year plan to install 33,000 new toilets and retrofitted further 24,000 toilet throughout the country (in Chinese only)   Guangdong Province's plan based on China's 3-year plan (in Chinese only)

 

Remote Monitoring System

 
Remote monitoring each bio-toilet system   Text alert and online notification when there is any abnormality in the system
