Is Chlorination the Way To Go?

There seems to be a lot confusion over which form of disinfection is likely to be the best choice for many tourism establishments. Previous regulations made chlorination virtually mandatory, but the new rules open up a range of other choices.

It is no coincidence that chlorination is almost universally used by municipalities and other large systems. It is extremely reliable and effective, and has the advantage of providing residual disinfection, that is, it protects water that may remain in the pipes for some time. Unfortunately, many operators have the impression that chlorination systems are costly and complex, and therefore not suited to their needs.

In fact, there are some very simple chlorination systems that can be used, and the flexibility that they provide can make them the best choice for many operators. An important advantage of chlorination is the simplicity of monitoring. You can determine that the water is safe by measuring the level of residual chlorine. This is a relatively simple test that the operator can perform. Where other disinfection systems may require samples to be sent to a lab at frequent intervals, self testing is generally possible where chlorination is used. Although periodic lab testing is still required, it is at much less frequent intervals.

Another advantage of chlorination is the ability to adjust for changing conditions. Where there is a short term increase in bacterial contamination, chlorine levels can be adjusted, based on monitoring, to maintain safe water. The levels are then re-adjusted when the bacteria count returns to normal levels.

All of this underscores the advantage of consulting a qualified engineer before any system components are purchased or installed. You’ll need sign off from the engineer for approval of any system you install, and getting the right professional advice at the beginning of the process will help insure that you choose the best system for your application.
