Coagulant-floculant problems

Hello, I have problem with coagulant which I'm using in our ETP. We are using this coagulant: Aluminum Chloride Hydroxide Sulphate, dimethylamine- Epichlorohydrin Copolymer. First one is with 15-30 % (w/w) Second one 5-12 % (w/w) Specific gravity = 1.025 (T = 298K) ph = 1.8 - 2.8 Viscosity 10-30 cps...

There is a lot SO4, SO3 and S from sodium dithionite and I need strong oxidizing agent for this reason, which can lower COD of the waste water. But you have already sulfur compounds in. The oxidation with Peroxide also will create sulfate. I didn't say it properly, srry about that. The idea is to h...

I will make detail explanation, so you will have more understanding about my situation. The main idea is to use H2O2 for oxidizing the components in the waste water because there is also a stable organic ( not hazard , toxic or so on.) components + sodium dithionite + NaOH, who increase the COD valu...

Mixing of hydrogenperoxide with hydroxide is a risk of self decomposition. Why not use sodium peroxodisulfate or other more safe peroxide compound. Carosh salt or something. I forgot to mention that we are using coagulant aluminum oxychloride. There is a lot SO4, SO3 and S from sodium dithionite an...

Mixing CO2 + H2O2 in specific environment

Hello, I almost 99.9% that nothing dangerous will happen, if I mix CO2 and H2O2 in specific environment, but the verification is the most advance shape of knowledge, so my question is: If I mix CO2 + H2O2 with waste water which have ph between 9.00 and 11.5(before neutralization with CO2), and the w...
