Pumped Chlorination (Chlorination Module) - Graf oneAdvanced Operation Manual

The usual carbon sources serving as nutrient solutions are:
Brenntaplus VP1 (recommended, available from Otto Graf GmbH: item no. 106556)
simple alcohols like methanol, ethanol, etc.
sugar solutions, syrup, molasses, etc.
The choice of carbon source depends on availability, C fraction (how effective is the agent?),
shelf life, thermal stability, and other factors. The nutrient solutions are generally harmless and
completely biodegradable. Please bear in mind that the nutrient content and the odour may at-
tract vermin (e.g. ants).
9.3.4.3 Dosing
The right C dose depends above all on the application. Approximate or calculated values are
therefore first entered for the dose and control unit settings during commissioning. Please refer
any questions to GRAF. Maintenance work may then readjust the dosage by changing the
runtime.
