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. This paper, "THE SMART SOLUTION TO MEMBRANE FOULING DETECTION, MONITORING AND MANAGEMENT", was presented at the 2015 IDA World Congress on Desalination and Water Reuse, San Diego, California, US.

The originality, simplicity and universal applicability of the MASAR® innovative SMART approach are exhibited in open-surface plant case studies of 5 trains from 3 different SWRO desalination plants in the Arabian Gulf. The plants feature different membrane configurations, models and manufactures. The data is evaluated comparatively using both the standard ASTM normalization method, as well as the proprietary corrected parameters based on site-specific conditions of each plant. The result is the establishment and constant monitoring of membrane fouling or non-fouling status for each case in the study and the measurement of its magnitude in real-time as the percentage differential between the two normalization techniques, known as the Fouling Monitor automatically calculated by the SmartAlarm software.
This result of these plant case studies show that the SMART approach, unlike most standard fouling management practices based on ASTM D-4516 methodology, is capable of detecting, measuring, monitoring and managing any fouling or scaling development that may occur in the system before it can cause significant and often irreversible losses in membrane performance characteristics.

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.
The paper, "REAL-TIME MEMBRANE FOULING MONITORING - A CASE HISTORY", was presented by PHWA Plant Manager at the 2001 WaterWorld’s World of Water Conference, Las Vegas, Nevada, USA.
MASAR Technologies, Inc., has conducted a trial for its SilentAlarm software at this 2.4 MGD (9,090 m3/day) plant, with Osmonics nanofiltration membranes. The well water feed TDS was around 765 ppm and the conversion ranged between 78%-84%. The plant experienced a biofouling history, followed by multiple cycles of cleanings (CIPs). Together with Skid 1’s operating data, covering around 3,700 hours of cumulative hours of operation, the the monitoring regime being utilized at the plant at that time, namely, monitoring the membrane DP and the so-called Fouling Factor.
Had the MASAR®'s SilentAlarm software been used as a real-time performance and fouling monitor at the plant, it would have alerted the plant operator of the first event of fouling at 100-200 hours , and corrective measures would have been taken to prevent the second-wave of fouling at 1,000 hours, saving a lot of valuable troubleshooting time and maintenance, not to mention costly loss of productivity and plant availability.
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.
