Praestol 2540 Equivalent — Medium-Charge Anionic Polyacrylamide
Praestol 2540 is a long-established anionic polyacrylamide used in wastewater treatment and in solid–liquid separation duty in mining. In the Praestol naming convention the leading digits identify the charge family and the following digits step the charge within it, so 2540 sits in the anionic series rather than the cationic one. Grade-level figures for it are distributed through the manufacturer data sheet rather than published openly, so we position against the service profile and the charge family, not against numbers we cannot source. Our matching product is a high molecular weight anionic polyacrylamide at medium anionic charge on our own scale — the same working position 2540 occupies in a municipal or mineral circuit. Set the grade on a jar or cylinder settling test against your current polymer, at your current dose, before you change anything; we ship a free trial quantity for that.

Dosage Guide
Municipal clarification duty typically runs at low single-digit ppm on the liquor; mineral settling duty is set in g/t on dry solids. Start from your current Praestol 2540 rate and confirm by jar or cylinder settling test before changing the dose.
Frequently Asked Questions — Praestol 2540 Equivalent — Medium-Charge Anionic Polyacrylamide
Is this the same product as Praestol 2540?
No. It is our own anionic polyacrylamide, made in our plant, positioned to do the same job in the same part of a circuit. We are not a licensee of Solenis and this is not a repackaged or copied product. The only honest way to establish whether it works for you is a side-by-side test against the polymer you run now.
Why do you not publish the Praestol 2540 charge density and molecular weight?
Because the manufacturer distributes grade-level figures through the data sheet rather than publishing them openly, and we are not going to put a number against their grade that we cannot source. What we can state is the charge family — 2540 sits in the anionic series — and the working position it occupies. Our own charge and molecular weight are stated on our own scale.
Can I switch straight over at my current dose?
Use your current dose as the starting reference, not as the answer. Two anionic powders at the same nominal position can still differ in dissolution time and in how they respond to shear in your mixing arrangement. Run a jar test on your liquor, or a cylinder settling test on your pulp, then step the rate until clarity and cake or underflow behaviour both hold.
We use several Praestol anionic grades. Does one product cover them?
Not automatically. Grades in the same anionic series step through different charge levels, and a step in charge changes the result on a real liquor even when molecular weight is comparable. Tell us which grades you run and on what duty, and we will send a trial quantity of the closest single match plus one step either side so you can bracket it on your own material.
What do I get with the trial sample?
A free 5 kg trial quantity, the batch TDS, COA and MSDS, and a written test protocol covering make-up concentration, ageing time and dose stepping. If your current polymer has a data sheet you can share, we will point out where our scale does and does not line up with theirs before you spend time on the bench.
