<p>Advantage brownstock defoamers are a family of proprietary products designed to remove entrained air and improve drainage in Kraft pulp mill brownstock washing systems, including drum and Chemi washers, deckers and filtrate systems.</p>
<p>The defoamers provide superior foam control and improve drainage and washing performance, allowing pulp mills to reduce shower flow and soda losses. These products also help mills increase filtrate solids going to the evaporators. This can improve stock cleanliness and reduce energy costs.</p>
<p>Commercial applications confirm that Advantage brownstock defoamers provide a number of benefits:</p>
<ul>
<li>Increased production</li>
<li>Improved fiber quality</li>
<li>Reduced operating costs</li>
<li>Reduced silicone carryover</li>
<li>Increased liquor solids</li>
<li>Improved drainage and washing</li>
</ul>
<p>Better yet, Solenis can provide all of these benefits with a new generation of Advantage brownstock silicone-based defoamers that can be produced with less impact on the planet. These new defoamers are made with 98.5 percent fossil-free raw materials*, yet they maintain a backbone of Solenis’ proven technologies so mills still benefit from best-in-class antifoaming capabilities. By end of 2023, our goal is to produce Advantage brownstock defoamers with certified 100 percent fossil-free raw materials — a demonstration of our strong commitment to reduce the impact of our products on the environment.</p>
<p>Advantage defoamers contain no dibenzodioxin (DBD) or dibenzofuran (DBF) or their precursors. They also contain no APEs, NPEs or animal derivatives and contain less than 1% VOCs per EPA Method 24.</p>

<h2>Automated Feed and Dosing</h2>
<p>Solenis offers a comprehensive portfolio of feed and dosing equipment specifically designed for use with Advantage brownstock defoamers. This includes everything from basic positive displacement piston or diaphragm pumps to Solenis proprietary SmartWash technology.</p>
<p>Solenis’ SmartWash technology is a powerful digital solution that helps customers gain both economic and sustainability benefits. SmartWash combines defoamer chemistry with the Solenis<a href="/en/research-and-development/innovations/onguard-i-controller"> OnGuard™ <em>i</em> Controller</a> to adjust dosing based on process needs. The OnGuard i Controller delivers an effective auto-adaptive dosing algorithm but with a relatively small data set. Mills that install the OnGuard <em>i</em> Controller benefit from a premier digital innovation, which, when combined with Solenis’ state-of-the-art brownstock defoamer technology, optimizes the washing process, stabilizes process conditions, and reduces costs. SmartWash is part of our full suite of advanced digital solutions at Solenis which include <a href="/en/products-and-services/digital-solutions/optix-applied-intelligence">OPTIX™ Applied Intelligence</a>, our full paper process AI application for chemistry performance optimization and daily operator insights.</p>
