INTRODUCTION
High-pressure driven reverse osmosis (RO) membrane filtration is capable of generating large amounts of ultrapure water for industrial applications. The excellent removal capacity of contaminants, decreasing prices for membranes, and enhanced membrane lifetimes led to widespread acceptance and popularity of RO. So Monitoring overall plant performance on a regular basis is an essential step in recognizing when membrane elements are becoming fouled. Performance is affected progressively and in varying degrees, depending on the nature of the foulants. RO cleaning frequency due to fouling will vary by site. we have to clean the membranes when they are only lightly fouled, not heavily fouled. Heavy fouling can impair the effectiveness of the cleaning chemical by impeding the penetration of the chemical deep into the foulant
The course shall present a cradle-to-grave strategy to preserve RO plant function, predict RO plant performance and avoid the failure of RO plant components, and ensure the highest permeate productivity with the best salt rejection. The course shall assist attendees to understand and manage properly any RO plant with best practice and the most cost-effective method. This should result in maximizing membranes and components life, reducing operating costs, and maintaining productivity and quality. and how to decrease plant performance when it is frequency performed and learn how to use the suitable chemical cleaning
