Urgent! Looking for advanced coagulant/flocculant!
(OP)
Hi, I am currently looking for advanced coagulants/flocculants that can efficiently treat most types of industrial wastewater: plating, dyed wastewater, emulsion wastewater, etc. Please let me know if your company manufactures or you know any of wastewater treatment products that are efficient, unique and environmentally-friend. Thanks in advance!

Nalco: it's hard to beat them. They (literally) wrote the book. When, some years ago, the company I was working for had some difficulties getting good floc from a treated buffered oxide etch suspension, Nalco sent out a service engineer by the name of John Fields. This guy took his suit jacket off and climbed right up on the treatment tank along with us until we got the process dialed in.
Generally; it's hard to find a 'one size fits all' polymer for the range of treatment operations the original poster describes. A thorough program of jar testing will bear rich fruits in avoiding problems later. I always preferred to do this myself, but a lot of the vendors will do it for you. If you go this route, make sure to provide truly representative samples of production waste to whoever is doing the evaluation.
It is better to provide raw wastewater and have the pH adjustment that immediately precedes flocculation performed in the lab doing the evaluating. The chemical reason for this: precipitated waste solids are rarely in a state of true equilibrium with the aqueous phase they're suspended in. Aging that mixture for some hours or days before the polymer evaluation can easily lead to erroneous conclusions.

Sometimes, you need to add baffles to a jars to acheive the mixing levels required for proper dispersion of coagulants.

Try Nalco, The Dober Group, Buckman Labs, or your local chemical supply guy.
