In the world of water treatment, the Silt Density Index (SDI) is the ultimate pulse check for your Reverse Osmosis (RO) system. High silt levels lead to membrane fouling, frequent cleaning cycles, and expensive replacements.
While manual testing is common, many facilities struggle with low feed-water pressure (less than 30 PSI), making accurate testing impossible. Shreyal Lab Industries, a premier manufacturer and supplier in India, solves this challenge with our specialized SDI Test Kit with Integrated Booster Pump.
What is an SDI Test Kit with a Booster Pump?
The Silt Density Index (SDI) test measures the fouling potential of water by calculating the rate at which a 0.45µm membrane filter plugs under a constant pressure of 30 PSI (2.1 bar).
If your raw water source doesn’t provide consistent pressure, your SDI readings will be inaccurate. Our Booster Pump Model ensures a steady, regulated flow, allowing you to perform reliable tests anywhere—regardless of the line pressure.
Key Features of the Shreyal Booster SDI Kit
As India’s leading manufacturer, we have engineered this kit for both field durability and laboratory precision.
1. High-Precision Booster Pump
- Self-Priming: Works efficiently even with low-pressure feed water.
- Consistent Output: Maintains the exact 30 PSI required for ASTM D4189 compliance.
-
Power: 220V AC / 50Hz (compatible with Indian industrial standards).
2. Complete Filtration Assembly
- Filter Holder: 47mm SS 316 / Plastic holder designed for easy membrane replacement.
- Pressure Gauge: Glycerin-filled, dual-scale gauge for vibration-free readings.
- Control Valve: High-quality needle valve for fine pressure regulation.
3. Portability & Protection
The entire system—including the pump, tubing, and stopwatch—is housed in a Heavy-Duty Carrying Case. This rugged design is ideal for field technicians moving between different RO plant sites.
