Filter underdrain with prefabricated cells |
摘要 |
An improved method for constructing filter underdrain systems may be provided which uses prefabricated underdrain cells. The prefabricated underdrain cells may have a one piece construction having side walls and a bottom. The side walls may include a porous plate support ledge with a ridge at the center of the ledge. The ridge helps ensure that the sealant forms a uniform and effective gasket when the porous plates are installed.
