The beta-site software was extensively tested, evaluated, and finally approved and recommended as an early-warning fouling indicator by the engineers of the world's pioneer in membrane desalination applications, DuPont’s Permasep Products, the original author of ASTM D 4516 "Standard Practice for Standardizing Reverse Osmosis Performance Data" (i.e., normalization procedures). See official DuPont testimonial letter below.
Analysis of process performance data was performed using a proprietary software package, MASAR®, procured from MASAR Technologies, USA (www.masar.com). The software was custom-designed for South Australia Water Corp.’s Penneshaw SWRO plant, based upon its configuration. MASAR® is able to predict the onset of long-term fouling more quickly than standard data-normalization methods. The MASAR® Fouling Monitor trend throughout the acid dosing trial is shown in the graph here.as presented at the 2007 IDA World Congress on Desalination and Water Reuse, Spain.
Design and operating data from RO Train A and NF Train A were recently provided by Port Hueneme Water Authority for evaluation using a new, early-warning membrane performance and fouling monitoring technology and software system known as MASAR® The difference in actual performance between the RO and NF trains as shown by the MASAR® evaluation results is truly remarkable. Both trains had suffered from biofouling, The plant had earlier discovered that the NF membrane elements also suffered from a manufacturing defect that resulted in the continuing deterioration of their performance as truly indicated by MASAR® software.
Are there any software which is used in desalination plant to monitor fouling and scaling? and can it be used to monitor or prevent fouling and scaling?
The innovative "Silent Alarm" technology discussed in the attached article makes a giant and an unconventional leap in that direction by allowing for real-time detection, measurement and monitoring of membrane fouling and scaling.from a manufacturing defect that resulted in the continuing deterioration of their performance as truly indicated by MASAR® software.
MASAR® is useful in testing and optimizing the effectiveness of new treatment chemicals such as coagulants, anti-scalants and biocides, either on pilot systems or on actual plant. It also helps test new processes or equipment (such as microfiltration) and their impact on RO performance and cost.
