jarthur. With respect, I strongly suggest that you and others go to https://www.phoslock.com.au. On a smart phone, you can scroll down to the very bottom where you will find some headings in blue. In particular "What We Do", and " Technology". There are several sub headings, that are links to a whole world of information that provides all that you have suggested & much, much more. You can then access / tap further into deeper layered links with feasts of technical and other information and be reassured for why you have invested in the global leader of water remidiation. You will marvel at the sheer weight and volumes of professional information and technical papers on offer from our company. Truly, take the tour so you can truly appreciate the company that is becoming, the company you have invested. You won't be sorry. There are no new questions here. Hi mickem, as requested, I'll edit respond to yours others a bit later.
