Introduction
Qualfloc™ PAM (polyacrylamide)
products are polymers manufactured and distributed by Bestac International for various application fields. Produced by
polymerizing of high purity acrylamides, the polymers are generally used as a
flocculant in an aqueous media to enhance the solid-liquid separation processes
and as a result, the separation speed is rapidly increased and the aqueous
media becomes clear and free of fine solid particles.
Water used in most industries (process water, mining,
wastewater etc) needs to be treated to reach acceptable environmental standards
for discharge or for recycling use back to the process. The water often
contains suspended fine solid particles which need to be separated and removed,
however these fine particles are normally very stable and do not settle readily
under gravity. In these circumstances, polymer flocculants and coagulants are
added to destabilize the suspension and solid particles are then flocculated
and rapidly separated.
Due to the broad spectrum and uncertain quantities of the
chemical, biological & mineral contents of the water to be treated, the
selection of
the correct product or product combination to reach
successful and cost efficient treatment
is vital. To this end we have developed an extensive product line to suit most
applications for solid-liquid separation include thickening (either by
settlement or flotation), subsequent filtration or centrifugation, sludge
dewatering etc. In most circumstances, it is more economical to use powder
grade polymer products than liquid or emulsion types. The obvious savings is in
the transportation and storage costs and generally, powders can also be
manufactured at lower cost when compared to emulsions. Our Qualfloc™ flocculants powder grade
product line include mainly:
·
Anionic PAM, Anionic charge: up
to 100%; Molecular weight: Low to Ultra High
·
Cationic PAM, Cationic charge: up
to 82%; Molecular weight: Low to High
·
Non ionic PAM, Molecular weight:
Medium to High
·
Amphoteric PAM where both anionic
and cationic charges are required
The anionic and cationic charge of our products can be made from
very low to almost 100%, molecular weight from very low to ultra high. Thanks
to the advanced microbiological process
that we use in producing our own high purity acrylamides (no copper, low
ferrous content, no inhibitors), which made our products ultra high molecular
weight possible. High molecular weight is an advantage in many cases and the
polymers will invariably outperform similar products of lower molecular weight
for rapid settlement or centrifugation where required.
Other than the standard application
for general use in water treatment industries, Qualfloc™ polymers can also be used in many other
applications for specific requirements. For oil industry, we have the Qualflood™ (Enhanced
Oil Recovery, EOR), Qualmod™
(Profile Modification), Qualmud™
(Drilling Mud Additives), Qualdrill™
(Shale Inhibition, Clay Stabilization). For potable water
industry, we have the Qualfloc™-W series, and for paper industry we have the
ultra soluble Qualfloc™-P series
that are developed for use as retention reagents. For agriculture, landscaping
& nursery and environmental protection, we have Qualsoil™-WC series product for water conservation, Qualsoil™-EC for land erosion control
and Qualsoil™-DC for dust control
etc. We also supply Polydadmac, Polyamine and dicyandiamide type coagulants.
Our major advantages:
·
Super high product quality using advanced
microbiological processing. Ultra high molecular
weight, low impurities, full range ionic charge
coverage, full line product for choice
·
Very competitive price. Economical to
use, effective at very low dosage levels

storage, extended shelf life
Our powder products and polyamine & polydadmac coagulants are
produced to comply with world health and environmental standards enabling these
polymers to be used safely in the food and potable water industries.
