Sanitizers for Irrigation Water
Chlorine, chlorine dioxide, ozone and peracetic acid are commonly used for disinfection of irrigation water.
Ensuring that the correct concentration of sanitizer is important to successful operation of the system. Many process control and HACCP procedures will prescribe the concentration (and type) of sanitizer to be used, which will need to be recorded and acted on accordingly. Too much sanitizer may effect the crops, whilst too little will not reduce the microbial or algal load in the water.
Some sanitizers can cause damage to crops when dosing is too high, whilst dosing levels too low can be ineffective and lead to contamination of produce.
