machine in a paper mill<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">In paper mills, large volumes of water are consumed during production, generating wastewater containing organic matter, fiber residues, and chemical substances derived from pulp. Discharging this untreated water causes severe environmental impacts, including water pollution, making wastewater treatment facilities indispensable to mill operations.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Wastewater treatment consists of several processes\u2014physical removal, chemical neutralization and precipitation, and biological decomposition by microorganisms. At the core of biological treatment is the <span style=\"font-weight:bold\">aeration tank<\/span> (also known as an <span style=\"font-weight:bold\">aeration basin<\/span>), where <span style=\"font-weight:bold\">microorganisms absorb oxygen from the air and decompose organic matter<\/span> to purify the wastewater.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/01\/nozzle-environ-013-image_03.jpg\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><br \/>\nAeration Tank (Aeration Basin)\u2014 Microbial Decomposition and Purification of Organic Matter<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">In this process, it is essential to ensure a stable air supply for the microorganisms and <span style=\"font-weight:bold\">maintain an optimal water temperature<\/span> for their activity.<\/p>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-bottom:0.8rem;background:url(https:\/\/www.dry-fog.com\/jp\/wp-content\/uploads\/sites\/2\/2024\/10\/10px-45px.svg) no-repeat 0 0;background-size:auto 30px;padding-left: 20px\">\n<h3 style=\"font-size: 1.5rem\">Challenges Faced by the Customer<\/h3>\n<\/div>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">A paper mill was facing difficulties in maintaining stable operation of its aeration tank, which is critical to the wastewater treatment process. During summer, rising ambient temperatures caused <span style=\"font-weight:bold\">the blower air supplied to the tank to reach nearly 70 \u00b0C<\/span>, consequently increasing the water temperature inside the tank. This rise in temperature reduced microbial activity, leading to <span style=\"font-weight:bold\">a decline in wastewater treatment efficiency<\/span>.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/01\/nozzle-environ-013-image_04.jpg\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><br \/>\nAir Blower for Supplying Air to the Aeration Tank<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Various measures\u2014such as reinforcing ventilation in the blower room and cooling intake air with fans\u2014were attempted, but none produced noticeable improvement. Installing an intercooler was not a viable option due to the high initial and operating costs. With no effective solution in sight, the facility engineers were left at a loss.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Amid these challenges, the customer consulted IKEUCHI to explore a method for <span style=\"font-weight:bold\">directly cooling the blower air<\/span> itself.<\/p>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-bottom:0.8rem;background:url(https:\/\/www.dry-fog.com\/jp\/wp-content\/uploads\/sites\/2\/2024\/10\/10px-45px.svg) no-repeat 0 0;background-size:auto 30px;padding-left: 20px\">\n<h3 style=\"font-size: 1.5rem\">Solutions Proposed by IKEUCHI<\/h3>\n<\/div>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">IKEUCHI proposed using the <a href=\"https:\/\/www.dry-fog.com\/en\/products\/noz-pne-bimj\/\" style=\"color: #00a273\" target=\"_blank\" rel=\"noopener\">BIMJ<\/a> Series air atomizing nozzle to inject <span style=\"font-weight:bold\">fine spray into the intake duct, where the evaporation of the mist directly cools the blower air<\/span>.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">The nozzle was supplied in a lance-type configuration suitable for duct insertion, creating a simple yet effective cooling setup.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/01\/nozzle-environ-013-image_05.png\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/01\/nozzle-environ-013-image_06.jpg\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><\/p>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-bottom:0.8rem;background:url(https:\/\/www.dry-fog.com\/jp\/wp-content\/uploads\/sites\/2\/2024\/10\/10px-45px.svg) no-repeat 0 0;background-size:auto 30px;padding-left: 20px\">\n<h3 style=\"font-size: 1.5rem\">Benefits Achieved<\/h3>\n<\/div>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\"><span style=\"font-weight:bold\">The blower air temperature, previously reaching 70 \u00b0C, was reduced to as low as 35 \u00b0C<\/span>\u2014within the optimal range of 20 to 35 \u00b0C for microbial activity\u2014creating an ideal environment for stable biological treatment.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Our sales engineer surveyed the site and recommended installing the nozzle at a position where complete evaporation could occur, based on the available straight length of the duct.
