3.4.1 Requirements for the calcium hypochlorite granulate
Description
Based on the experience gained in the past 30 years with the dosing of calcium hypochlorite granulate
using the GRANUDOS system, we discovered that the quality of the granulate has a significant impact
on the dosing’s functional safety. Here, we define our minimum requirements for the calcium hypo-
chlorite granulate. If these quality criteria are met, a proper dosing operation can be assumed.
The following can be checked upon delivery to gain an initial impression of the quality:
The granulate must be white, free of clumps, and no strong chlorine odour must be present when
opening the drum.
