Octolig by MGI out of Colorado has a proprietary heavy-metals selective ligand binding resin that we looked at using for mine drainage (nickel mines).
I know they have some plating waste stream experience, so you may want to give them a call to check your particular stream.

Anyone know off the top of their heads what ASME/ANSI standard deals with socket (fusion) welding of small ID ( < 3") Halar (ECTFE) chemical service piping?
Thanks in advance.
If he is using diatomaceous earth as the filter aid, it will be a costly system to operate!
Check with your local regulators. Depending on the specifications of the filter, performance testing, selection of filter aids, and previous approvals you might be able to get away with it. In domestic...
I may be a little off base here, but the whole question of "engineer" vs. "Professional Engineer" is one more of a legal nature, based on professional and personal liability. Personally, I am a degreed and licensed Professional Engineer in the Province of Ontario. As a...
Membrane manufacturers? It will depend if you want membranes themselves or membrane systems. It will also depend on the market/projected use.

Hi Mike,
It will all depend on the type of salts, their concentrations and the levels that you wish to reach. There are a lot of methods to remove salts, but if your client is concerned about cost they may not be terribly happy with any of them.
You can do on-line searches for removal of...
Sodium Bisulfite, very common in dechlorination operations. Typically (38wt% sol'n NaHSO3, 1.3 s.g.) stoichiometry is around 1.46 mg/mg. Rule of thumb would be to oversize the dosing requirements to account for poor mixing kinetics and non-ideal reaction parameters, 5-10% oversize (the...
Hmmm. Without an analysis of what is in the groundwater it is difficult to say exactly what may be causing the corrosion. The type of pump and location of the corrosion are also helpful (i.e. length of contact period, specific areas, different metals which may act as a galvanic cell with an...
I am trying to determine the most probable corrosion rates for brass hydrant components in a stagnant (treated, disinifected) water system. We are looking at a potash biocide treatment, with an estimated concentration od 100 to 150 ppm. Ideally the solution will be in contact (non-flowing)...
