What is Chemical Wastewater Treatment? (with pictures)
What is Chemical Wastewater Treatment? (with pictures)

25/1/2021, · Acidic wastewater typically has a pH value lower than seven, and must be made more basic through chemical processes. Very specific amounts of basic chemicals are added to acidic tanks in order to neutralize the contents. Lime is the most commonly used base, as it is easy for specialists to measure just how much to add.

it can be discharged into a munici-pal sewage system. Cleaning fluids, process chemicals, and excessive sewage require process-ing through a series of tanks where neutralizing chemicals are added, and waste materials are allowed to precipitate. The resulting sludge is removed to a dump site, and the “clean” wastewater is released into

Wastewater treatment issues: Cyanide destruction questions

As far as I know, you ,can, neutralize cyanide with a Sodium Hypochlorite solution (Bleach) under basic conditions (pH = 9-11) which will oxidize cyanides (CN-) ions ,into, cyanates (CNO-) ions. However cyanate is also toxic (not as much, but still), but I read that you ,can, transform them ,into, NH3 and CO2 by adding a strong inorganic ,acid, to cyanates ( bringing to pH =2).
