Provide Safe & Simple Pool Sanitization
Ensuring your pool's water is properly sanitized is a crucial job for aquatic facility operators. There are ways to make this job safer and more simple.
Q: Is there a safer, simpler way to sanitize my pool?
A: Onsite chlorine generation could be the answer.
Let's look at simplicity first. Onsite chlorine generation is essentially a one-step process. You add a small amount of salt to pool water—ideally through an automated feeder—as it passes through a chlorine generator. The generator uses DC electric current between positively and negatively charged plates to convert the salt in the water to sodium hypochlorite, a form of chlorine, at near-neutral pH in a sufficient concentration to disinfect the pool water. Self-cleaning systems use reverse polarity to remove calcium buildup on the plates, reducing maintenance requirements.
Systems are sized to produce a specified number of pounds of chlorine to meet disinfection needs based on the size of the pool—or multiple pools if the chlorine generator can feed multiple pools.
Onsite chlorine generators solve a number of cost and safety issues. First, there are no delivery or storage issues with salt, typically bought in 40-pound sacks. Salt delivery requires no special hazmat trucks with special permits and restrictions, nor does salt require any special storage facilities. Additionally, the cost of salt is lower and much more stable than the price of bulk chlorine.
Because the onsite-generated chlorine is pH-neutral, fewer chemicals are needed to stabilize pH levels. That reduces cost, but most important, it reduces the biggest cause of chlorine gas releases, the most dangerous hazards associated with bulk chlorine.
Pool owners and operators typically add muriatic acid to the water to stabilize pH, and when the acid and chlorine are accidentally mixed by human error, fires or explosions can occur. More often, an accident creates a cloud of highly toxic chlorine gas that can lead to respiratory problems that require emergency medical responses and hospitalization. In some cases, the gas cloud can be deadly.
Finally, safety and cost come full circle when you consider that a chlorine-related incident can cause a pool to be shut down until conditions are remediated.
