Pollution Index SDI TesterAQUALYSIS 100SDI is not only suitable for online installation and use, but also for mobile use. Users can flexibly choose the installation method according to the actual situation on site. The recommended usage and installation method is online, which is a fixed online installation method that meets the standard configuration of an automatic SDI analyzer. Widely used in water supply plants, sewage treatment plants, steel/metallurgy, petroleum/chemical, power, papermaking, textile/printing and dyeing, brewing, fine chemicals, pharmaceuticals, coal mines, food and beverage, electronics/circuits, electroplating/surface engineering, energy, seawater desalination, ships, boilers, etc.
Pollution Index SDI TesterMeasurement principle:
During installationDuring the SDI analyzer process, users can set the sampling port on the pipeline before entering the reverse osmosis system. The usual practice is to connect a three-way valve on the main pipeline, and a valve needs to be installed on the sampling pipeline to open and close the sampling. To prevent debris from entering the pipeline of the automatic SDI detector, it is recommended to install a pipeline filter. The SDI measuring instrument sampling tube is directly or indirectly connected to the pipeline filter through a conversion joint. If the sampling pipeline is too long, a bypass with an overflow valve must be installed, and a long flow of water must be maintained inside the sampling pipeline to prevent debris from settling.
Pollution Index SDI TesterConcentrate the functions of bypass, venting, and drainage in one drainage pipe, which is a 10mm transparent plastic pipe. The drainage pipe is ultimately inserted into the drainage ditch.
