Pet in perspective, page-29

Hi Kev
hopefully you will have more luck with this one. a don't really see them as a competitor to PET but, different use ? many of our projects are smaller one offs so setting up a plant might not be feasible and on big lakes where setting up might be worth it looking at the volumes per day/ hours treated treating a big lake might take so long, then what would be the cost firstly and i would think these would be treating to water column and not sediment where more of the ph gets released from from time to time so if trying to treat that the system would need to be in place full time, ie can't just have a moblie plant at a small lake for 1 month and then leave
