Hi!
I seem to be out of the loop at work. Too embarrass to ask my coworkers to explain it to me.
Can anyone explain what nucleation and seeding is?
Our process is basically a precipitation process where copper is precipitated by reacting Ca(OH)2 to Cu(OH)2. We have a sedimentation tank...
According to the downstream team, the anthracite was not contaminated with Leonardite. I forgot to mention that the order of the sandfilter is anthracite, sand, pebbles, then gravel.
Would the oxidize antracite produced quinones at a pH of 4-7? How about if MnO- is present? Would only a...
Thank you for all the help.
We're coordinating with the downstream team to have a small-scale experiment with a mini chelate tower model. We're waiting for the downstream teams evaluation. Hopefully, the small-scale experiment will bear positive responses.
Our team is running around in...
Do anyone know what would cause brown discharged from sandfilter?
The sandfilter is compose of gravel and anthracite.
Would reducing agent particulary SO4 react with antracite forming brown discharged?
The sandfilter is used to reduced copper and clear water. However, in this instant...
Would you happen to know what would be the specific effect of chlorine to the chelate resins? Is it the formation of CuCl2 that would result to high Cu of the treated water of chelate? According to the manual for the resin my supervisor read, the effect of chlorine interchanges the selectivity...
Wow! Thank you dadgad, that really helps. From the information I got downstream, the chelating resins are a styrene-divinylbenzene copolymer introduced iminodiacetate.
The structure is basically a R-COONa.
Added question, do reducing agent such as sodium metabisulfite affect the chelating...
From what I understand with our downstream's chelate towers, it only absorbs the Cu2+ ions and not exchange ions with the waste. They said that since hypochlorite is an oxidixing agent, it makes the resins release the copper ions already absorbed by the resins. I find it dubious considering what...
I need help.
In my work place (we mainly treat copper contaminated water), our downstream are pointing the chlorine content of our water for the cause of their copper concentration going up after the waste has gone through their chelate towers. This chlorine content shows no visible indication...
