Waterway dredging and algae emergency management are commonly applied in open water environments such as rivers, lakes and urban landscape water bodies. These operations are often seasonal or emergency-driven, involving collected materials with high moisture content and elevated organic matter, typically consisting of mixed algae and sediment. Limited site conditions place higher demands on equipment mobility, continuous operational stability and adaptability to variable material characteristics.
Waterway Dredging and Algae Emergency Management
Industry Background
Technical Approach
To address the high moisture content and unstable structure of mixed algae and sediment, the system follows a process route of pre-thickening followed by mechanical dewatering. Collected materials are conveyed into the thickening stage for volume reduction before undergoing solid-liquid separation in the dewatering unit. The process is designed for continuous operation, with a compact equipment layout that allows rapid installation and commissioning under temporary or emergency site conditions, effectively reducing downstream transport and disposal requirements.
On-site Photos
The photos below show a Haibar dewatering unit supplied to Brazil in 2022 for a river dredging and algae removal project. The equipment was used on site to treat mixed materials consisting of algae and dredged sediment with high moisture content and organic load. During operation, the system demonstrated stable continuous performance, smooth dewatering and well-formed sludge cake, meeting on-site transportation and downstream disposal requirements and supporting effective emergency waterway management.
