Optics-SDI Analyzer is an intelligent online control
system engineered for continuous and automated
operation in desalination and other advanced
water treatment processes. Designed for seamless
integration, it supports both local and remote
monitoring, delivering precise and reliable SDI
measurements while ensuring safe, cost-effective
operation.

The Silt Density Index (SDI) is a critical parameter
for evaluating the quality of feed water entering
reverse osmosis (RO) systems. It serves as a key
indicator of whether the pretreatment system is
effectively protecting the RO membrane.
Maintaining optimal SDI levels is essential to
prolonging the lifespan and efficiency of reverse
osmosis units.
