ASTM on Data Normalisation

2024-12-02T06:11:57Z

Matt:

ASTM D4516 - Standard Practice for Standardizing Reverse Osmosis Performance Data

Membrane performance (flux and salt passage) is affected by: water temperature, feed conductivity, and flux rate. If the operating arameters remain constant the system will perform fairly steadily over a long period of time. However, these operating conditions will eventually change. Normalisation is a technique that allows the user to standardise the data to a constant set of conditions (or to a reference), and may be used with SCADA for online diagnostics.

==Flow or flux performance==
===Specific flux===

<math>
\operatorname{Specific Flux} =
\frac{Flux \times TCF}{NDP}
</math>
<p>
Where:
<math>
\operatorname{TCF} =
e^{x}
</math>
</p><p>
<math>
x = u\left( \frac{1}{T+273} - \frac{1}{298}\right )
</math>
</p><p>NDP = Net Driving Pressure</p><p>
<math>
NDP = P_{feed}-\Delta \pi-\frac{\Delta P}{n+1}-P_{permeate}
</math>
</p>
<p>
<math>
P_{feed} =
</math>
RO feed pressure</p>
<p>
<math>
\Delta \pi =
</math>
Osmotic Pressure</p>
<p>
<math>
\Delta P =
</math>
Feed/Brine Differential Pressure</p>
<p>
<math>
n+1 =
</math>
Number of membrane stages</p>
<p>
<math>
P_{permeate} =
</math>
Permeate back pressure</p>
<p>
<math>
\pi = 0.006 \times
</math>
Average feed / brine conductivity</p>
<p>
<math>
\text {Average feed / brine conductivity} = \text {Conductivity of feed} \times \left [ \frac{\ln \left ( \frac{1}{1-Y} \right )}{Y} \right ]
</math>
</p>
<p>
<math>
Y = \text {Recovery} = \frac{\text {Permeate flow}}{\text {Concentrate flow} + \text {Permeate flow}}
</math>
</p>

===Normalised Flow===
<math>
\text {Normalised Permeate Flow} = \frac{\left ( NDPs \right ) \left ( TCFs \right )}{\left ( NDPa \right ) \left ( TCFa \right )} \text {Actual Flow}
</math>
<p>
<math>
a = \text {actual}
</math>
<br>
<math>
s = \text {standard}
</math>
</p>

==Membrane rejection

===Normalised Salt Rejection===

===Normalised Permeate Conductivity===
<math>
\text {Normalised permeate conductivity} = \text {Permeate conductivity}\left ( \frac{\text {Actual permeate flow}}{\text {Standard permeate flow}} \right )\left ( \frac{\text {Standard feed/brine conductivity}}{\text {Actual feed/brine conductivity}} \right )\left ( TCF \right )
</math>

==Feed/brine channel blockage/fouling==

=== Normalised differential pressure===
<math>
\text {Normalised}\ \Delta P=\Delta P\left [ \frac{\left ( \text {Standard feed/brine flow} \right )^{1.5}}{\left (\text {Actual feed/brine flow} \right )^{1.5}} \right ]\left [\left ( T-25 \right )\left ( 0.017 \right ) +1 \right ]
</math>
<p>
<math>
\text {Feed/brine flow}=\frac{\left ( \text {Feed flow} + \text {Concentrate flow} \right )}{2}
</math>
</p>
