Qualfloc™ PAM Flocculants for Paper Industry
We supply a full line of powder
flocculants and liquid coagulants which are suitable for many different types
of paper production and paper mill wastewater treatment plants. Major
applications for our products in the paper industry:
·
Paper
Retention Aids-Anionic & Non Ionic
·
Paper
Retention Aids-Cationic
·
Paper
Dye Fixer & Formation Aids
Qualfloc™-P series of retention reagents
have been specifically developed for single retention reagent application or
combined (with minerals or organic coagulants) treatment applications. Polymers
can be used as a retention reagent on the machine for paper fibers and fillers
to obtain optimum water utilization and enough retention. Polymers can also be
used for drainage improvement during paper manufacturing. Normally, higher
molecular weight polymers are good for retention improvement and lower
molecular weight polymers are good for drainage improvement. Depend on the type
of fibers and fillers, a retention aid with proper molecular weight
should be chosen by balancing out the importance of
retention and drainage functions as required. Lab testing and plant testing for
choosing the best polymers are suggested.
Qualfloc™ polyamine and
polydadmac coagulants are used generally together with an anionic retention aid
providing the cationic charge to enable the dual product system to function
correctly, to neutralize the charge on anionic trash in the water circuit, as a
fixing agent to control the 'stickiness' in the coated broke and together with
AKD and ASA sizes to improve cure rate.
Qualfloc™-P series of cationic and anionic flocculants can be used for
the treatment of white water and wastewaters from the paper processing. It is
normally used together with Qualfloc coagulants and polyaluminium
chloride (PAC) coagulant for best results. For sludge dewatering after the
thickening or flotation stage, Qualfloc cationic polymers are normally
used.
