Lovibond Silt Density Index (SDI) Test Kit for Reverse Osmosis Plants

Portable Silt Density Index (SDI) field test assembly engineered for reverse osmosis feedwater, enabling fouling time, backwash frequency, and membrane lifespan calculations in just 15 minutes.

Technical Specifications

Testing Capacity 100 Tests (Includes 0.45 µm Membranes)
Application Reverse Osmosis (RO) Feed Water Evaluation

Full Product Description

The Silt Density Index (SDI) measures the particulate, colloidal, and suspended solids content of water, serving as the industry standard benchmark when commissioning and operating Reverse Osmosis (RO) plants. Calculating feedwater SDI is essential to project membrane fouling rates, optimize pre-treatment filtration, schedule backwash intervals, and preserve membrane longevity.

The Lovibond SDI Test Kit (Order Code: 56K001901) utilizes a specialized membrane/flow meter system enabling complete, standardized SDI calculations in just 15 minutes.
