产品描述
Parameters
RizonSDI®Automatic SDI is an online control system designed for continuous, automated desalination processes and other water treatment projects. It can be monitored automatically or remotely. To achieve accurate test with safe and economical operation, replace the tedious operation of manual test, avoid human error.
The pollution density index (SDI) value is an important parameter of inlet water quality index of reverse osmosis system, and is the main means to check whether the effluent of the pretreatment system meets the inlet water requirements of reverse osmosis system. Its size is crucial to the operation life of reverse osmosis system.
Product Features
- Fully comply with ASTM D4189-07 standard
- 24 hours, 365 days of continuous automatic operation
- One measuring point is set up in the system, which can be increased to 2-4 points according to needs to measure 1-4 channels of different water quality
- According to the system time to a fixed cycle, to achieve automatic measurement without external signals; Remote monitoring can also be carried out by external input control signals. The measurement period of each channel is optional between 1-999 hours
- At the same time both 4-20mA analog output signal and switching alarm output signal
- The chassis protection level is IP65
- Alarm types include temperature alarm, abnormal pressure alarm, diaphragm shortage alarm and pollution index over limit alarm
- With HSDI-0645-MCE film coil, each coil test can reach 80-100 times
- When the inlet pressure is less than 3Bar, a booster pump is required
Product advantage
- On-line real-time monitoring of SDI value, LCD LCD display
- With power down protection, digital filtering technology, with strong anti-interference ability
- Query history and system alarm records at any time
Application field
- desalination
- Municipal water treatment
- petrochemical
- Electric power
- laboratory
- Online monitoring
