<h3 style="text-align: left;">Introduction</h3>
<p style="text-align: left; font-size: 10pt; font-family: Arial;">The PUAR (Processing Unit areas Fairing) is a polyester unit for trapping pollutants attached to settle solids (SS) contained in the polluted water from areas fairing and maintenance of boats prior to discharge into the port. A significant fraction of the pollution (zinc, lead, heavy metals ...) is indeed attached to the SS.</p>
<h3 style="text-align: left;">Opération</h3>
<p style="text-align: left; font-size: 10pt; font-family: Arial;">PUAR is composed of three compartments, each with a distinct function :</p>

<h3 style="text-align: left;">Conception</h3>
<p style="text-align: left; font-family: Arial; font-size: 10pt;">By design reinforced polyester fiberglass, PUAR is perfectly adapted for aggressive water and saltworks.</p>
<p style="text-align: left; font-family: Arial; font-size: 10pt;">All elements that constitute the units are stainless steel, polypropylene or polyester.</p>
<p style="text-align: left; font-family: Arial; font-size: 10pt;">The structure of the PUAR polyester filament wound following type orthogonal circumferential and longitudinal axes allows a high mechanical strength, including a facility in groundwater.</p>
<h3 style="text-align: left;">Benefits / Maintenance</h3>
<ul style="text-align: left;">
<li style="text-align: left;">
<p style="font-family: Arial; font-size: 10pt;">For ease of maintenance, large openings were planned: filter access is easy and the latter, removable, can be removed for cleaning</p>
</li>
<li style="text-align: left;">
<p style="font-family: Arial; font-size: 10pt;">A column with a firefighter drain connection allows rapid extraction of a sludge safely.</p>
</li>
<li style="text-align: left;">
<p style="font-family: Arial; font-size: 10pt;">In addition, the polyester resin lining inside the PUAR prevents the attachment of heavy material at the bottom of the unit.</p>

<div style="width: 81%; float: left; padding: 5px;">
<p style="font-family: Arial; font-size: 10pt;">To manage SS and stored hydrocarbons, a typical alarm AHB can be installed.</p>
<p style="font-family: Arial; font-size: 10pt;">It detects:</p>
<p style="font-family: Arial; font-size: 10pt;">A level of oil in the separator compartment before closing</p>
<ul>
<li>
<p style="font-family: Arial; font-size: 10pt;">Deposition of sludge in the sludge compartment</p>
</li>
</ul>
<p style="font-family: Arial; font-size: 10pt;">It includes PVC, a probe and probe box oil sludge.</p>

</div>
<ul style="text-align: left;">
<li>
<p style="font-size: 12pt; font-family: Arial;">Collars polyester or polyethylene</p>
</li>
</ul>
<p style="font-family: Arial; font-size: 10pt; text-align: left;">To upgrade the access of UTC TN coast, the collars are available.</p>
