Online SDI15 Sludge Density Index Analyzer for RO Systems with 0.45μm Membrane and IP66 Rating
Professional monitoring solution for reverse osmosis systems with precision measurement and industrial-grade durability.
- Water treatment plants and wastewater treatment facilities
- Industrial sectors: steel, metallurgy, petroleum, chemicals, power generation
- Manufacturing: papermaking, textile/dyeing, brewing, fine chemicals, pharmaceuticals
- Additional applications: coal mining, food & beverage, electronics, electroplating, energy, seawater desalination
- Equipment systems: marine vessels, boilers, and other industrial processes
The SDI15 analyzer supports both online fixed installation and portable operation. For optimal performance, we recommend permanent online installation aligned with standard automatic SDI analyzer configurations.
Position the sampling port upstream of the reverse osmosis system. Standard practice involves connecting a tee joint to the main pipeline with a control valve on the sampling line. Install a pipeline filter to prevent debris entry, and connect the analyzer's sampling tube via an adapter downstream of the filter. For extended sampling lines, include a bypass with overflow valve to maintain continuous flow and prevent sediment accumulation.
The integrated drainage system combines bypass, venting, and drainage functions through a single 10mm transparent plastic tube routed to drainage trenches.
