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.
In order to design a suitable pre-treatment regime for a new facility or optimise an existing one, it's important to characterise the nature of the feed water. Depending on customer requirements, in addition conventional chemical analysis of the dissolved compounds present, this may involve:
