Hi there,
I am looking to purchase activated carbon beads (carbon beads that have been activated by temperature or steam; not chemicals) and I was wondering about the best UK suppliers. Has anybody got any good recommendations? Failing UK suppliers, are there any other companies that may be able to help me?
The beads I am looking to use cannot leach any Phosphorus into the water effluent; this is a very important requirement.
Best regards,
Jack
You can find many suppliers here :

among them several in UK and Europe in general. They sell several products, so you just have to ask for materials physically (not chemically) activated.
I don't recommend one with respecte to others. Just ask free sample for your tests ... Norit provides easily such free samples, well-characterized, in general.

Dr. Lee,
It appears that you're strictly interested in carbon "beads" rather than the more common form of granular activated carbon (GAC) as Dr. Celzard has suggested. GAC has a highly irregular particle shape that can occur in different morphologies. The term AC "beads," however, is more commonly used to refer to spherical extruded AC particles of extremely uniform size and shape. Spherical AC is a rather novel shape for carbon sorbents, and there aren't many manufacturers that produce it.
However, if you're simply looking for GAC, Dr. Celzard's suggestions above are good. FYI, "temperature" activated carbon is more commonly referred to as thermally activated carbon or steam-activated carbon (if steam is used as the activating agent). Also, even with a very pure activated carbon there will likely be a very small amount of phosphorous leaching. You'll have to determine for yourself if that amount is significant or appreciable.
Best of luck in your search, Dr. Lee.
