Description

Filter skid sampling device for biological monitoring of ballast water Embodiments of the present invention relate to a filter skid sampling device for biological monitoring of ballast water, specifically a filter skid sampling device for biological monitoring of ballast water that applies and optimizes the sampling standards presented by the International Maritime Organization (IMO) using a closed-type filter skid sampling device. Existing ballast water sampling technology has primarily been developed as portable equipment for testing laboratories. While such portable devices perform one-time sampling and analysis on board, they have limitations in that they cannot continuously implement real-time monitoring on the vessel itself. In particular, because these devices cannot track or continuously monitor the condition of discharged water in real time, there has been a persistent need for automated monitoring devices installed on ships. Furthermore, existing sampling devices are designed to require filter disassembly for sample collection, which increases the risk of biological loss or damage during the process. This filter disassembly process degrades test accuracy and raises concerns that the collected samples may not accurately reflect the actual condition of the effluent. Therefore, technical improvements are necessary to minimize biological loss during sample collection and obtain more reliable test results. As international regulations on ballast water management become stricter in the future, there is a growing need for sampling devices that can be installed on ships to provide automated, real-time monitoring. Such devices must be compatible with analytical equipment and developed to meet the sampling guidelines set forth by the IMO (International Maritime Organization). However, equipment that meets these requirements has not yet been developed, and technology to address this issue is required.
