A professor of engineering has created a new portable water reclamation system which could radically change the way the military deals with its wastewater at forward operating bases and has potential for deployment during civil emergencies. The wastewater system, built into a repurposed shipping container, is highly efficient, low power, and low maintenance.
“Currently, human wastes are typically burned in burn pits, and the wastewater is usually hauled away and dumped by local contractors. This results in high costs, security issues, potential health risks, negative environmental impacts to the hosting country and a potential negative image.” – Dr. Jianmin Wang
Dr. Jianmin Wang, professor of engineering at Missouri University of Science and Technology, designed the wastewater containers with few mechanical parts, and says they are designed tough enough to be deployable on site by helicopters. Although the system was created with the military in mind, Wang says it could be deployed just about anywhere, including small rural communities with no wastewater facilities.
Wang’s system is called a baffled bioreactor (BBR), and it modifies the conventional activated sludge process by using baffles to create an intermediate settling chamber for sludge return which is maintenance-free. The wastewater system uses low
