<p>The OnGuard <i>i</i> controller is a truly unique chemical feed and control system that allows for around-the-clock surveillance and control of process and water treatment chemical programs. Both a performance-based and knowledge-based chemical control system, the OnGuard <i>i</i> controller makes it possible to automate even the most demanding chemical programs.</p>
<p>When used in conjunction with Solenis’ state-of-the-art analyzers and chemical technologies, the OnGuard <i>i</i> controller ensures the optimal performance of the treated system. Key benefits include:</p>
<ul>
<li>Improved operational efficiency</li>
<li>Reduced water and energy use</li>
<li>Reduced downtime</li>
<li>Reduced costs</li>
<li>Prolonged asset life</li>
</ul>
<h2>How It Works</h2>
<p>By combining hardware and proprietary software into one water treatment equipment package, the OnGuard <i>i </i>controller enables plant managers and engineers to customize chemical feed and control parameters. Standard chemical feed algorithms can provide basic control. Or advanced performance-based and knowledge-based algorithms can provide more sophisticated control.</p>
<p>A powerful coprocessor performs the complex calculations defined by the software. This turns the OnGuard <i>i</i> controller into an intelligent machine capable of learning about a plant’s unique operational environment. With this data, the controller can then implement the most effective corrective actions.</p>
<p>The OnGuard <i>i</i> controller can be configured to provide customized chemical feed and control for virtually any process and water treatment application.</p>
<p>Every automation project requires close collaboration between plant personnel and Solenis experts, who recommend key operating indicators (KOIs) and key performance indicators (KPIs) for the specific application. The installed KOIs and KPIs are transmitted to the OnGuard <i>i</i> controller either directly from individual analyzers and meters or indirectly from the customer’s distributed control system.</p>
