3.1
Regeneration/disinfection of GENO-mat
MN-Z demanganisation systems
Note:
We recommend to have the regeneration/disinfection per-
formed by Grünbeck’s authorised technical service/authorised ser-
vice company.
3.1.1 Oxidant
Designated area of application:
Oxidizing agents are used for the regeneration and disinfection of
deferrisation and demanganisation systems; they are also dosed up-
stream of deferrisation and demanganisation systems in order to
completely oxidise iron II and manganese II compounds.
The dosing and the dosing volumes depend on the iron and manga-
nese concentrations contained in the raw water.
You can use either our GENO special granulate
1)
or
GENO-oxi plus (liquid).
3.1.2 Preparing the regeneration agent
Fill the regeneration tank with filtered water (for respective quanti-
ties refer to Table G-1). We recommend installing a filling tap in the
pure water pipe for this purpose.
Pour the GENO special granulate
1)
or GENO-oxi plus into the tank
and mix using the integrated hand mixer until the special granulate
has dissolved completely.
Install a suction hose between the regeneration tank and the ball
valve at the control valve.
