Ground Water Puzzle
Ground Water Puzzle
(OP)
I have a ground water bore that has a high concentration of iron (40ppm) Manganese 2ppm Magnesium 10ppm and H2S. With pH adjustment and aeration I can get the majority of the contaminents out.
I am looking for various methods of removing the flock with a continuos feed period of approx 12-14hrs. 100,000 litres required per 24 hrs
I have been informed that the use of upflow clarifiers can have problems with temperature differential.
I will utilse the water in a fish farm and the minimal use of chemicals is of desire.
Thanks

RE: Ground Water Puzzle
polymer flocculants can attach to fish's gills and kill them, so be careful there.
Following pH adjustment, use filtration methods, e.g. sand filters would work well at 20 gallons per minute, or increase settling basin retention time. Allow the metal hydroxides to settle unassisted.
Not sure where you are getting the temp differential. Can you explain? Also not familiar with upflow clarifier.

what is the pH of the water at the moment,.
RE: Ground Water Puzzle
Temperate diff problems with well designed upflow clarifiers only really where there are extreme temp differences. Can be got round by insulation.
