How can I check chlorine levels after using chlorine disinfection tablets?

Instachlor tablets by Palintest are rapidly dissolving chlorine tablets that can be used for a number of disinfection and water treatment applications. They contain sodium dichloroisocyanurate (NaDCC) which is an organic chlorine donor that when added to water, releases a given amount of chlorine into solution. The applications of Instachlor are wide ranging from personal water disinfection for travellers up to the disinfection of water storage tanks on board ships. Instachlor tablets carry BS EN 12931 approval making them a suitable chemical for water treatment of water for human consumption. You can read more here. They are however only intended for casual or periodic water chlorination so it is not recommended that supplies of treated water are consumed for more than 90 days in any given one year period.

Instachlor range comes in a number of different tablet strengths.

A slow release alternative to Instachlor tablets are the Steadichlor range, which are designed for applications involving flowing water, such as the continuous treatment of flowing water systems and disinfection of repaired mains.

How many tablets do I need for my application?

The Instachlor tablet range comes in a number of different strengths, and tablets are named such that they provide that level of available chlorine in mg/l when added to 1L of water. For example, 1 x PR-1000 tablet added to 1L of water will provide 1000mg/l of available Chlorine. This can be scaled for your given water volume. Palintest provide in depth guidance about the different levels of chlorine needed for your application, and you can check out the instructions sheets here.

Do I need to measure the chlorine levels?

It is recommended that you measure the chlorine levels to check that an adequate chlorine residual is achieved in your treated water. The Chlorocol pocket test kit is a wide range, simple-to-use chlorine test designed specifically for this application. It contains enough tablets for 50 tests and a colour changed is observed which correlates the levels of chlorine present in your sample. It is available here.
