BASF globally launches new cationic powder flocculant range with Zetag® ULTRA for high dewatering performance at low dosage rates. We have summed up this contribution in our corporate purpose: We create chemistry for a sustainable future. BASF had sales of € billion in 2012 and more than 110,000 employees as of the end of the year.
Placed by BEA Mountain Mining Corp., part of Aureus Mining Inc., the order covers one 21mdiameter highrate thickener, two belt linear screens (9 m2 and 6 m2) and a flocculant plant with auto dilution for increased steadystate conditions.
The ultrahighrate thickener is sized mainly on hydraulic loading and would therefore have a smaller diameter (and hence, smaller footprint) than the equivalent highrate thickener. The size limit of this type of thickener (12m diameter) may therefore require multiple thickeners to handle the full stream.

It is an ultrahigh molecular weight anionic polyacrylamide flocculant supplied as a free flowing granular powder. FlocREADY 1524P is a high performance product designed to improve clarification and dewatering operations. FlocREADY 1524P has found application in a wide variety of mineral processing operations including the following:
further increase of the feed rate to 650 m 3 h1 sees the thickener close to overflowing for the higher dosage with no further increase in underflow volume fraction, while a stable low bed is ...
In high solids, a flocculant (such as a high molecular weight polymer) that produces large aggregates might have lower settling rate than a flocculant that produces smaller aggregates (such as a low molecular weight flocculant), which does not reflect a better performance of the latter flocculant, but simply wall adhesion effects in a narrow ...

However, fluctuation of an interface level between clear and unclear areas of the thickener can effect flow rate adjustment. The purpose of such an override is correction for errors in the mass control signal as well as for changes in flocculant feed rate.

Bridging flocculation is typically found to be most effective when ultra high molecular weight polymers, (5 to 15 MDa) are used in relatively low dose such that less than about half the surface area of the particles has adsorbed polymer. If the dose is higher such

Again, feed solids concentration, flocculant dosage, system hydraulics and so forth will be examined to define parameters important for sizing and operating a high rate thickener. Continuous high rate thickening tests to examine feed rate (hydraulic stress) versus flocculant dosage and feed solids sensitivity at known pH.
