Design and Operating Data Parameters

The following are operating and design data parameters utilized by the Membrane Alarm System and Automated Reporter, MASAR^®. Each record data set must contain at least the parameters listed under Required Data, in order for MASAR^®'s database and operating system to produce the desired output and for all system features to function properly. The required parameters are the same as required by the industry-standard normalization technique (ASTM D 4516 Method - Standard Practice for Standardizing Reverse Osmosis Performance Data), which is the basis for all normalization programs available mainly from the membrane manufacturers (see footnote below). Also required is a set of train/stage design projection data (all parameters listed under I. plus the projected product flow and salinity). These will be used as the basis for normalization of data (i.e. Standard Conditions); they should represent the average actual current conditions as much as possible, according to ASTM D 4516. The following parameters apply to all membrane processes: Reverse Osmosis (RO), Nanofiltration (NF), Ultrafiltration (UF) and Microfiltration (MF), except as noted.

  II. Required Parameters

1.     Train or Skid Name, Number or ID.

2.     Stage Number (1,2 or 3).

3.     Date Data Set Collected.

4.     Operating Hour (total operating time excluding membrane system shutdowns).

5.     Feed Temperature (first stage input only).

6.     Feed Salinity or Electric Conductivity - RO & NF only (first stage input only).

7.     Feed Pressure (input to each stage).

8.     Membrane Pressure Drop (feed pressure minus brine pressure directly across the average pressure vessel in each stage)

9.     Product Pressure (output from each stage) if available- final value is adequate.

10.  Final Reject or Brine Flow (output from the last stage)

11.  Product Flow (output from each stage)

12.  Product Salinity or Electric Conductivity - RO & NF only (first stage input only).

13.   No. of Pressure Vessels On-line (per stage)

14.  No. of Membrane Cartridges per Pressure Vessel On-line (per stage)

  II. Optional Parameters

1.     Turbidity "NTU" (Membrane system feed)

2.     Silt Density Index "SDI" (Membrane system feed)

3.     Micron Filter Pressure Drop (Membrane system feed line)

4.     RO Feed pH (Membrane system or common acidified feed line)

5.     Redox Potential or ORP reading (Membrane system or common feed line)

6.     Chlorine Residual (Membrane system or common feed line)

NOTE: IF STAGE DATA IS NOT AVAILABLE, OVERALL SYSTEM DATA (as one stage) CAN BE USED BUT IT WILL BE LESS ACCURATE AND RESULTS CANNOT
            INDICATE STAGE-SPECIFIC PROBLEMS.

Custom Features
Customization options such as data input/output, screen displays, custom reports and graphs are available upon request.

Data Transfer/Evaluation
Your plant operating data, previously entered in any MSExcel^® spreadsheet, or MSAccess^®, dBase^® or other database file format (including data files from any membrane manufacturer's normalization program such as NormPac^®, NormPro^®, RODATA^®, ROSA^®, etc.), can be accepted and evaluated by MASAR^® so that your plant's full operating and performance history can be available, and you continue to enter new data into the system without interruptions or loss (custom option with licensing).
