Around 2.25 the lab tech is a bit clumpsy; why not write the labels first, then stick em to the beakers.

Hello sir I got two questions: 1) If we need to add a coagulant aid (flocculant) to increase the flocs size and to add lime or soda to adjust the pH value, how to proceed it with mining wastewater polluted with cyanide and heavy metals.
2) Which coagulant, flocculant and adjust pH are good for that. Thank you so much.

For cyanide add sodium hypochlorite and naoh. till ph between 9.5 to 10.5. agitation. required. then add flocc like alum and lime

[@rajibbarman5194]

How different strength of alum is made?

[@omk9853]

How the flocs are settle down without addition of polyelectrolyte?

[@lalalayeyeyeye3576]

polyelectrolytes and aluminium sulphate are both floculating agents

[@RamRam-eh7ix]

Bs rest karna do settle down ho jayega

[@cevredoktoru3627]

I got two questions;
1)hoe many minutes or seconds we will wait at 100rpm velocity?
2) how much al sulphate add ?how do we know the proper quantities? Do we have a basic data sheet table etc...

[@sithararao8408]

To answer your questions:
1) We have to do 100rpm for 1 minute
2) We have to take in graduation of 2 ml, 4 ml, 6 ml, 8 ml and 10 ml
