How Ceramic Membranes Help Reduce SDI Before RO Systems
SDI, or Silt Density Index, is an important indicator used to evaluate the fouling potential of water entering an RO system. High SDI usually means the water contains suspended particles, colloids or other fine contaminants that may block or foul RO membranes. Ceramic membranes can be used as a pretreatment technology to reduce turbidity and […]
Why RO Pretreatment Matters in Industrial Water Treatment
Reverse osmosis is widely used in industrial water treatment, desalination, wastewater reuse and high-purity water production. However, RO membranes are sensitive to fouling, scaling and suspended solids. Without proper pretreatment, an RO system may face frequent cleaning, pressure increase, reduced permeate flow and shorter membrane life. RO pretreatment is designed to protect the RO system. […]
