Product Description
We have been serving our clients with a quality tested range of Silt Density Index Kit in the market. Silt Density Index (SDI) is an empirical test developed for measuring the rate of fouling of nano-filtration (NF) or RO membranes. Suspended solids and colloidal materials in feed water are one of the biggest problems in reverse osmosis systems. This parameter is used in seawater reverse osmosis (SWRO) applications to objectively measure the compatibility of the incoming water with the reverse osmosis membranes. Silt Density Index Kit can be availed at reasonable prices.
Precise Filtration Analysis AnywhereEngineered for field and laboratory use, the SDI Kit utilizes high-quality stainless steel and polycarbonate to withstand tough conditions while ensuring precise measurement of particulate fouling in water. The bench-top or hand-held design adds flexibility, and analog display with stopwatch enables instant and accurate time-tracking.
Effortless Operation with Full AccessoriesThe kits manual operation requires no external power and comes complete with all necessary accessories from filter holders to tubing. This ensures ease of setup and seamless testing, whether for reverse osmosis plants, water filtration monitoring, or laboratory quality control.
FAQs of Silt Density Index Kit:
Q: How is the Silt Density Index (SDI) test performed with this kit?
A: The SDI test is conducted by passing water through a 0.45 micron filter paper at a controlled pressure of 30 psi, using the included pressure gauge, tubing, and filter holder. A stopwatch and graduated cylinder record the time it takes to filter a specific volume (typically 500 ml), and the SDI value is calculated using the standardized formula.
Q: What types of water analysis is this kit suitable for?
A: This kit is ideal for water filtration analysis, reverse osmosis (RO) membrane evaluation, and routine water quality checks in both field and laboratory environments, providing SDI values within a 06 range.
Q: When should I use the SDI Kit during my water treatment process?
A: Routine use of the SDI Kit is recommended before and after filtration stages, especially before water enters RO or membrane systems, to monitor and control particulate fouling, thus protecting membranes and maintaining system efficiency.
Q: Where can this SDI Kit be operated?
A: The portable design and wide operating range (0100% humidity, 0C to 50C) make the kit suitable for onsite field applications, remote water sources, or laboratory settings. Its lightweight build and no power requirement enhance ease of transport and convenience.
Q: What are the main benefits of the SDI Kits construction and design?
A: The kit features robust stainless steel and polycarbonate components for durability, accurate 99% retention at 0.45 micron, manual control for reliability in any location, instant flow readings, and a full set of accessories for efficient operation and quick deployment.
Q: How accurate and reliable are test results from this kit?
A: Test results are highly reliable, with a measurement accuracy of 0.2 SDI and a resolution of 0.1 SDI, fully compliant with ASTM D4189. The analog display and included stopwatch help ensure consistent and precise data collection.
