AI Thread Summary
Designing a machine for reclaiming industrial wastewater involves selecting appropriate flocculants for effective treatment of effluents like spent degreasing water and CNC coolant. The discussion highlights the need for guidance on how to choose flocculants and questions the feasibility of a universal flocculant that could work across various types of wastewater. Additionally, there is a query regarding the necessity of neutralizing pH levels before the treatment process. Participants in the discussion reference existing threads and resources for further information on flocculation.

Hey guys,

I am interested in designing a machine for clarification (reclaiming) industrial wastewater from a plant. The effluents to be treated would be Spent Degreasing water, spent cnc coolant or other process water.

I would be looking to use Flocculants for this purpose. Please see this video for reference -

My question is how do you select the flocculants? And will there be a possibility of 'One-Floc-Suits-All' type of additive that would work with different effluents?

And is it necessary to neutralize the pH before treating the effluent?

Thanks,
KV

Lots of information on this including a couple of threads on here.

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
