In pulp and paper making processes, the presence of water, heat
and organic material continuously being processed is a favorable environment
for microbial contamination. The addition of biocides is intended to eliminate
any form of biofouling and to also prevent contamination on the end-product,
visible as spots on the paper film.
Lonza provides an extensive range of oxidizing
biocides, preservatives, halogen stabilizers and surfactants to address
bacterial development during the wet-end process.
Lonza’s calcium hypochlorite and range of organic
biocides, such as our Isocil®, Bardac® and Barquat® biocides, are also used to treat
the raw water that is used in the process.
Lonza Equinox® 15 Stabilizer is a formulation aimed
to stabilize active chlorine and maximize its efficiency where the biofilm is
building. When the Lonza Equinox® 15 Stabilizer treatment program is compared
to sodium bromide and ammonium sulphate based treatment programs, Lonza
Equinox® 15 Stabilizer has a favorable ecotoxicological profile, rapid
biodegradation and a low vapor corrosion generation. Equinox® 15 Stabilizer has
been used globally for decades in the pulp and paper industry.
