    Calculating dissolved water to work out BOD in a waste water treatment activated sludge design?

    Hi everyone, I'm currently designing a waste water treatment of a plant that manufactures interferons. This is the last process I need to design and I am done! yay. I have decided to use an activated sludge system and I need to work out the Biochemical Oxygen Demand levels in the influent and...

    Waste water treatment - Activated Sludge design

    Are you referring to the method about obtaining information from a similar facility? Also is there a site I could go to in order to find similar facilities?

    Waste water treatment - Activated Sludge design

    I meant consumed/dissolved sorry and there is not much literature I can find on this. Would I work the oxygen consumed by each component of the affluent stream and make a total?

    Waste water treatment - Activated Sludge design

    So i'm designing a plant that manufactures interferons. I've completed a majority of the plant and now i'm left with treating the waste water of the system. I am required to calculate the amount of oxygen produced by all the substrates in the waste water and to design a settler/clarifier. I'm...

    Waste treatment for my manufacturing plant

    Okay so say i've made waterwaste treatment system up to the secondary treatment and the effluent stream from the last unit of the secondary treatment is in agreement with the discharge levels.. Would I require disinfection? or could I just straight dispose of it anywhere

    Waste treatment for my manufacturing plant

    So i've been told by my mentor that I should concentrate on the secondary treatment mainly. 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...

    Waste treatment for my manufacturing plant

    I'm having trouble finding any literature on water discharge however I have found levels that shouldnt be exceeded for suspended solid levels and dissolved oxygen levels. I'm not sure if that would be sufficient? Also from what I have researched thus far, I could combine all the streams into...

    Waste treatment for my manufacturing plant

    In order to do that I need to determine whether to group all streams into one stream and treat them in a unit as one stream? Then I could determine the volume flow and COD right? The various streams include cooling water, pichia pastoris (yeast cells), interferon & growth medium, waste...

    Waste treatment for my manufacturing plant

    So what I need is less to do with the disposal it's more of the treatment I need to concentrate on. 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...

    Waste treatment for my manufacturing plant

    The disposal method must be economically feasible and fit Hong Kongs regulations as this is where the plant is located. 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!

    Waste treatment for my manufacturing plant

    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...
