Bridging the GAPs: Approaches to Treating Water On Farms

I M P L EM E N T I NG AG R I CU L TU R A L WA T E R T R E A TM E N T S ON TH E F A RM

In this module, we will focus on both system evaluation as well as troubleshooting if problems arise. We will cover basic components, methods for monitoring chemicals as well as devices and approaches for correcting issues as they arise. We’ll also discuss a multitiered approach to water treatment and monitoring.

Components of water treatment systems

There are several components of water treatment systems that we have covered in the previous sections of this module. In this module we’ll reinforce some of those concepts.

Calcium hypochlor ite chlor inator

A calcium hypochlorite chlorinator is one option growers have for treating their irrigation water. This system uses a 68% calcium hypochlorite tablet. Just as with other forms of chlorine, the active ingredient is hypochlorous acid.

These tablets are similar to pool chlorination tablets, though those tablets have other ingredients added. Tablets for agricultural water treatment must be compatible with the chlorinator system. There are various sized systems available for irrigation water treatment, based on the flow or volume of water going through the systems.
