Greetings Tebogo. As William alludes to, it depends on how, where and the duration of storage. The original supplier is always a good starting point. After that you need to consider how you are making up the products and then how long you are keeping prior to dosing. Dosing is another consideration, are you using static mixers etc. is your maintenance good. Finally, how does the composition of you waste water vary over time (relatively stable or prone to fluctuations)?
