The SludgeKing AquaCat roll-off dewatering container from Park Process uses filters that radius to the bottom of the container, leaving no corners for cake to stick to and no residual water left in the container. This radius also increases the length of the wall filters, providing additional filtration surface area. The two center panels increase the filtration area by 33 percent more than containers with only one center filter wall. The increased filter surface area and the more narrow biosolids compartments formed by the additional filter wall translate into drier cakes formed in less time. With the decreased distance between two filter walls, water has less distance to travel before exiting the container, which means faster dewatering times. 855/511-7275; www.parkprocess.com
