Waste treatment for my manufacturing plant
Waste treatment for my manufacturing plant
(OP)
Hi guys,
So I'm currently designing a PFD which looks perfect at the moment in regards to all the mass balances and units like my batch reactors, centrifuge, ultrafiltration, cation exchange column etc....
Only problem i'm faced with currently is how to treat the waste coming out of the system.
I have a a stream with pichia pastoris, a stream with waste proteins and medium, elute waste, sublimated phosphate buffer. Does anyone have any knowledge on the best way to dispose of them safely?
Thanks for reading.

RE: Waste treatment for my manufacturing plant
We probably need a bit more information on things like concentration and quantity, and what are your options for disposal.

RE: Waste treatment for my manufacturing plant
I'll find out and get back to you on the conc. and quantity, however what's the significance of the concentration and quantity?
Also thanks for the reply!
RE: Waste treatment for my manufacturing plant
Concentration and quantity gives an indication on what sort of process might be viable.
If for example you had only a few litres of waste the solution may be very different to if you had a million litres of waste.
Likewise a very diluted waste might be dealt with differently to a very concentrated waste.
I don't think many of us would be familiar with Hong Kong's regulations , but what options do you think might be available eg: to sewer, to land to ocean etc, or do you have to be zero discharge and you could look at recycling.

RE: Waste treatment for my manufacturing plant
I haven't been able to find much on the exact numbers for discharge levels, however I have found suspended solid levels need to exceed 20 mg/l and dissolved oxygen levels need to exceed 4mg/l... Is that sort of the same thing?
Also it be advisable to group all streams into one and treat them in a unit as one stream? If so what sort of unit?
I've found that activated carbon is really good for waste water. In regards to above would I could the addition of all streams as waste water and treat it as such?
Sorry for all the questions aha

Then I could determine the volume flow and COD right?
The various streams include cooling water, pichia pastoris (yeast cells), interferon & growth medium, waste proteins & medium, elute waste, sublimated phosphate buffer
RE: Waste treatment for my manufacturing plant
In most application, the total wastewater stream can be combined. To treat an individual stream, there would have to be a characteristic that is present that would make it more cost effective to separate the stream.
RE: Waste treatment for my manufacturing plant
Also from what I have researched thus far, I could combine all the streams into one and treat as such:
Pre treatment (screening, grinding and equilization) -> Primary Treatment (pH adjustment and to remove nutrients) ->Secondary Treatment (Removes soluble biodegradable organics) -> Tertiary Treatment (Removes non-biodegradable organics) -> Disinfection (Removes Living organisms) -> Disposal (Remove/accumulate redisual matter)
Would this make sense?

I'll research further into everything and get back to you if anything strikes a chord
RE: Waste treatment for my manufacturing plant
From research, i've found that secondary treatment involves the following units: Activated Sludge -> Aerated Lagoon -> Trickling Filter -> Anaerobic Lagoon -> Stabilization basin
Does this sound suitable to the various streams in my waste water?
Also i've been seeing that a filter bed is more efficient than activated sludge, if so why is it not being used in main industries?
Thanks

A biological filter may work

Would I require disinfection? or could I just straight dispose of it anywhere

RE: Waste treatment for my manufacturing plant
If you direct discharge, it is likely that disinfection will be required. Not so for indirect discharge.
Most industrial plants attempt indirect discharge since the permitting requirements are more abbreviated.
The other wastewater discharge parameters will also be spelled out in the permit.
