Treatment on a trailer

摘要

When a water treatment plant in northern England faced a spike in pesticide concentration exceeding the allowable concentration limit for incoming water, the facility had to shut down. Plant managers then used a regional facility's water until the problem could be solved. Their temporary purification solution arrived in a 20-foot steel shipping container. In it were a bulk bag discharger and two flexible screw conveyors made by Flexicon Corp. of Bethlehem, Pa., and Transvac Systems Ltd's ejector system for mixing and injecting a slurry of powdered activated carbon (PAC) into the water stream.
