Basics on Level Measurement: Principles, Types, and Applications
Introduction Level measurement is the process of determining the height, volume, or quantity of a material inside a container. Materials can be liquids, slurries, powders, or bulk solids. The objective is to obtain accurate and continuous or discrete readings of the level for process control, safety alarms, inventory management, and automation. Industries such as chemical … [Read more...]
Silt Density Index (SDI) in Desalination: Principle, Measurement, and Importance
💧What is SDI? Silt Density Index (SDI) is a measure of the fouling potential of feed water, especially important for RO membrane protection. It estimates how much particulate matter (silt, colloids, bacteria, etc.) would clog a 0.45 µm filter over a standard time. The SDI was introduced by ASTM as a standard fouling index to address the growing need for a reliable … [Read more...]
