Water treatment pressure vessel having internal conical distributor plates

摘要: A pre-manufactured fiberglass reinforced plastic ("FRP") tank may be fitted with one or more conical internal diffuser plates (also termed nozzle plate, filtration chamber separator plate). To insert the plate into FRP tank, a liner is cut perpendicular to axis of and along sidewall so as allow complete access inside tank. The results in two opposing substantially equal surfaces that mate weld grooves on plate. first face welded mating groove side while other creates hermetic seal between interior exterior both welds. second time, times, install additional required. Each has wall section now becomes an extension completes liner. One riser tubes can installed through central openings plate(s) provide for ingress egress liquid from
