Programming
The below procedure describes the general rules and procedures for proper programming of the bleed set point
and chemical dosing pumps.
The effective bleed set point should be defined by the owner or by its representative (contractor, water treatment
specialist,...) in function of the following parameters:
•
Make Up water quality parameters
•
Materials of construction: refer to the "Water Care" on page 7 and the submittal information of the
BAC equipment
•
The water treatment program implemented, including formulation and concentration of biocides and anti-
scale / anti-corrosion inhibitors
•
The system volume to be treated
Anti-scale and anti-corrosion dosing is made in function of the make up water quality. An impulse will be given to
the dosing during XX minutes / YY seconds after each XXX liters of make up water.
Biocide will be dosed in shock during X minutes / YY seconds at regular interval (weekly or daily mode).
Pre-bleed is done before dosing and bleed lock out to be made for X hours / YY minutes after dosing.
