Sodium hypochlorite is a well-known and aggressive oxidizer that is used in many applications. Our end-use customers often use “hypo” in the water treatment business to eliminate bacteria and viruses from water supplies.

Anyone looking to maintain a safe and secure storage tank system has three challenges to overcome: UV rays, off-gassing, and oxidation. Over the years, Poly Processing has established a set of industry leading best practices that represent an ideal sodium hypochlorite storage system for overcoming these challenges.

A wide variety of colors are available for polyethylene storage tanks. Cosmetics to match the surrounding buildings and landscape, customer preferences, and the application or the chemicals being stored are factors determining tank color selection. However, one color which is almost always selected for higher end storage solutions, such as storing harsh, aggressive chemicals such as sodium hypochlorite, is black.

One of the challenges in storing any oxidizing chemical is engineering a tank that not only stores the chemical but has a greater life expectancy and a measure of safety. Whether you’re storing sodium hypochlorite, sulfuric acid, hydrochloric acid, or other oxidizing substances, it is critical to design the storage tank with the chemical in mind.

Proper tank design is crucial to successful safe chemical storage. Purchasing a chemical storage tank isn’t just about selecting the right size — it is vital to design the proper tank configuration for the safety of your employees, the protection of the environment, and to leverage your investment.

When you have questions about chemical storage or concerns about your chemical storage tank system, you want quick answers. You want to know who to call and get a live voice without getting the runaround. A solid customer service team takes great pride in delivering service that saves you time and eliminates any hassles.

Poly Processing's tanks are manufactured in the United States and are able to accommodate a wide variety of fittings and locations of fittings. This flexibility allows for proper inputs and venting, ensuring a safe and effective solution for a given chemical and longer tank life as well. A common point of confusion that we hear from customers is: Which fittings can I use on my tank, and where can they be installed? We've tried to simplify the answer to that question by considering each area of the tank and the corresponding compatible fittings. 

Seismic codes govern structural design to prevent damage to buildings and structures during an earthquake. It’s common knowledge that buildings must conform to specific seismic codes, but your chemical storage tanks also have seismic regulations. Any facility in a seismically active region, including everywhere along the Pacific Rim, must pay careful attention to the safety measures established in the International Building Code.

Chemical leaks present several major challenges for your facility. They can cause damage to storage systems, employees, and the environment. Repair and cleanup costs can be expensive, and the leaked chemical is wasted.

Twenty years ago, the availability of commercial grade cross-linked polyethylene (XLPE) for chemical storage tanks was limited to a small number of sources. The limited supply, as well as a wide variation in quality, made it challenging to find quality resin for chemical storage tanks. 

Maintaining the proper temperature of a chemical inside a high density crosslinked polyethylene tank can be critical for safe and effective storage. For example, sodium hydroxide and caustic soda need to maintain temperature to prevent crystallization at lower temperatures.
