Ultraviolet (UV) rays can play havoc, not only on light-sensitive chemicals such as sodium hypochlorite (NaOCl), but on the storage tank itself. Snyder-Crown has developed a new HDLPE resin for storage tanks which not only stands up to UV rays, but also keeps them out.
HDLPE #880059, a new opaque white resin, was specifically designed for storing NaOCl. Its opacity prevents UV rays from attacking the sodium hypochlorite while its white colour reflects the sunlight. Reducing exposure to these decomposition catalysts means longer shelf life for NaOCl.
Rotationally molded polyethylene (PE) tanks have homogeneous walls. Without any fibres for the chemicals to wick along, there is consistent corrosion resistance throughout the tank. PE tanks also have excellent impact resistance, which minimizes damage to the tank during shipping and installation.
Tank performance is dependent not only upon the materials used, but also on the manufacturing process. Snyder-Crown designs the tanks so that the resin is in the bottom knuckle radius of the tank. Snyder Unitized Molded Outlet (SUMO®) helps maximize tank drainage to remove sedimentation that can occur with time.
HDLPE #880059 opaque white tanks may provide a cost-effective alternative for storing sodium hypochlorite for the water treatment, wastewater treatment, pulp and paper, or chemical processing industry.
