The Genesys Membrane Laboratories in Madrid, Spain, provide a range of services specifically designed to identify the causes of membrane failure in reverse osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) plants.
In order to optimise the operation of a membrane plant it's essential to fully understand the chemical nature of the feed water. From statistical analysis of the results of membrane autopsies we've carried out over the past ten years, we have concluded that more than 50% of membrane fouling and failure events result from inadequate pre-treatment. Other common causes of failure include incorrect antiscalant and chemical dosage.
Membrane replacement cost are a significant factor in long term operational expenditure, any increase in membrane life is a welcome addition to a chemical treatment regime. Freuent poorly controlled cleaning preocedures can result in membrane damage with a consequent deterioration in performance. Taking into account lost production and input of man hours membrane cleaning can become an expensive process.
