<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 all types of 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 several benefits:</p>
<ul>
<li>Lower carbon footprint</li>
<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>
<h2>Fossil-free Solutions</h2>
<p>Solenis can provide all of the above benefits with a new generation of Advantage brownstock silicone-based defoamers that reduce the impact on the planet. These new defoamers are made with 100-percent fossil-free raw materials*, yet they maintain a backbone of Solenis’ proven technologies, so that our customers still benefit from best-in-class antifoaming capabilities. Our goal is to continue expanding our portfolio of certified fossil-free Advantage brownstock defoamers — supporting Solenis’ commitment to establishing emissions reduction targets according to the Science Based Targets initiative (SBTi).</p>

<h2>SmartWash Technology</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 component to any brownstock defoamer program 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 <em>i</em> 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/optix-applied-intelligence/">OPTIX™ Applied Intelligence</a>, our full paper process AI application for chemistry performance optimization and daily operator insights.</p>
