The main issue was low-quality oxygen from the concentrator, which was limiting performance, so we replaced the internal material and restored it to full operating condition. We also performed full maintenance on the air compressor and serviced key <a href=\"https:\/\/www.oxidationtech.com\/ozone\/ozone-system-design.html\">ozone system components<\/a>, all of which are now working properly. On the next visit, we will replace a short section of air hose and add a label to ensure the concentrator stays in the correct setting.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Monarch Blvd \u2013  Internal Summary<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Service visits:<\/strong>&nbsp;Dec 22\u201323, 2025 and Jan 12\u201313, 2026.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Application Background:<\/strong> The Monarch Blvd site is a <a href=\"https:\/\/www.oxidationtech.com\/applications\/water-treatment\/wastewater.html\">lift station <\/a>application.
