APPARATUS FOR COMPRESSION OF A STACK AND FOR A WATER TREATMENT SYSTEM

摘要

The present disclosure is directed at a modular apparatus for a water treatment system. The apparatus includes multiple internal modules that are compressively coupled to each other. Each of the internal modules includes a pair of rigid end plates located at opposing ends of the internal module, and a stack of membrane bounded compartments that are layered from one of the end plates to the other. Each of the rigid interior end plates includes an electrode, and the electrode of one of the rigid interior end plates is electrically connected to the electrode of the other of the rigid interior end plates to complete an ionic circuit through each of the internal modules. The present disclosure is also directed at a non-modular apparatus including a stack and a compression device for compressing the stack to prevent leaks. The stack includes a pair of rigid end plates located at opposing ends of the stack, a plurality of membrane bounded compartments layered between one of the rigid end plates and the other of the rigid end plates and fluid manifolds extending through the membrane bound compartments. The compression device is fixedly coupled to opposing ends of the pair of rigid end plates and includes compression members movable to compress one of the rigid end plates towards the other of the rigid end plates. The compression members are positioned to apply force to the stack in the vicinity of the fluid manifolds.
