Dongqi Crane & Equipment Corporation proudly serves a wide range of industries, providing top-quality services and solutions for diverse applications such as clean room cranes, aerospace critical lifts, and water management equipment.
Frequently used in wastewater treatment applications, our high-performance lifting solutions set the standard for specialty handling.
To ensure safety and reliability across all processes, the equipment used in water system management plants — such as heavy-duty jib cranes, bridge cranes, and gantry cranes — must meet strict environmental standards.
Wastewater, or used water, must be treated before being released back into the environment. Not only is this key to preserving natural marine environments and fisheries, but it also fights pathogens and harmful downstream microbial effects. Sinks, showers, washing machines, toilets, dishwashers, and countless other commercial appliances and products all create wastewater.
Treatment plants work to remove or reduce pollutants and suspended solids before safely releasing the remaining water, or effluent, back into the natural environment. These plants handle all types of waste, oils, and chemicals. The acceptable processes and standards for regulating these waters are set by the Estados Unidos government and include:
Industrial Effluent Guidelines: Administered by the United States Environmental Protection Agency (EPA), these serve as national regulatory standards for the management of wastewater discharged into surface waters, as well as municipal sewage treatment plants. The EPA bases these standards on the performance of treatment and control technologies.
Clean Water Act (CWA): This was first enacted in 1948 to establish a basic structure for regulating water pollutants and managing the quality standards for United States surface waters. Water quality standards for contaminants and pollution discharge are managed and enforced by the EPA through this act.
The wastewater treatment process can be broken down into several distinct steps.
First, preliminary treatment separates large pieces of trash, protecting equipment and isolating heavy material to be sent to landfills. Waste materials and the primary sludge are pumped through a cyclone degritter for removal. Primary treatment filters and removes finer sand, grit, and gravel.
Secondary treatment and disinfection remove impurities and harmful organisms through chemical and biological cleaning processes. This may involve chlorine contact tanks, in which water is literally bleached with sodium hypochlorite.
Finally, sludge treatment handles the remaining material, which is still 99% water. The solid material is separated through thickening then run through the digestion process to make it safe for the environment before its final dewatering.
Wastewater management requires a significant amount of heavy lifting, and specialty cranes are key to this process. Depending on the application, various types are available, including:
Bridge Cranes: These are used for changing and lifting plant filters. They offer superior load positioning due to their 3 axis design.
Jib Cranes: Jib cranes are used for changing and lifting plant filters. These can be floor mounted and offer circular space coverage. Jib cranes sometimes require special foundations or support. Light capacity jib cranes may be mounted directly to a standard concrete floor.
Gantry Cranes: These are used for lifting, moving, and placing pumping stations, motors, valves, and blowers, as well as digester removal and rehabilitation. Highly versatile gantry cranes are not mounted, allowing for free mobility and custom height adjustments. These specialty cranes are used for moving heavy loads in outdoor settings, with the ability to safely and efficiently handle the tremendous weight.
Whether managing complex regulations or particularly sensitive loads, the team at Dongqi Crane proudly provides high-quality tools and solutions to tackle even the most complex material handling challenges. Increasing both workplace and environmental safety, our overhead solutions meet and exceed CMAA standards while optimizing installation, management, and equipment movement processes.
