EDTA is a very good start for research purpose, but I'm a bit
leery of adapting it to production work, because it is very
nondegradable and stay in the surface water for a VERY LONG
TIME, and it started to cause problems. If you dump EDTA into
sewer system, it goes right through the treatment plants and
gets dumped to the ocean. At least, EDTA solution should be
reused until it becomes ineffective, to minimize the quantity.
