Thanks for this interesting presentation. I am a wastewater engineer more into the activated sludge process and trickling filters of domestic wastewaters and this was a good overview of the MBBR technology.
Hi Douglas! Thank you for your kind words. We are glad to be able to share our knowledge and educate! If you have any other questions feel free to reach out to us at info@ssiaeration.com!
thank you very much for the excellent work. One thing is not clear to me. When you compare mixing requirements by media type you define 4.5 m3/h for SSI media but correct me if I'm wrong do you mean 4.5 m3/h*m3 of media? thanks!
It is one of the best presentations ever seen in before related to the Biological filtration of MBBR treatment systems in different industrial applications. Thanks a lot for your great efforts.. May i know your official email for commercial consultation services for us in India? we have requirements. So kindly share your company details for approaching you for consulting service to our company in India. We are looking forward. Thank you!
Hi Abhi, Thank you so much for your kind words! If you want to reach out directly to doreen@ssiaeration.com I can put you in contact with our team. We have an office in Hyderabad but also have a separate MBBR/Process team based out of the USA. I can introduce you to both teams and we can take a look at your requirements and go from there. -Doreen
@@ssiaerationinc Hi, I just spoke to your person from Hyderabad. I belong to this region, only I'm very much surprised your company is located here, very nearer to me. Thank you, we have clearly sent our requirements to your local office. Thanks for your kind support.
Why do Fine Bubble Aeration Diffusers require more periodic maintenance than Coarse Bubble Diffusers? I've been at a startup plant site for each currently in operation and wasn't quite aware of that. A really solid presentation though.
hi! Fine bubble diffusers have smaller slit sizes vs coarse bubble so its much easier for the slits to get clogged which can impact airflow. if the slits get clogged the membrane can stretch, tear. Coarse bubble have much large holes and have a higher airflow going through them so they are less likely to clog. The trade off though is reduced efficiency, higher energy costs
Is there such thing as 'RAS' equivalent in MBBR in case you need more biology? Also why is the limit 200 microns for biofilm thickness. And wouldn't you need DO of
Hey! Its a bit of a long answer and could depend on your particular installation. If you want to talk to one of our MBBR experts more about it we would be glad to go into the technical details for your application. Send us over an email at info@ssiaeration.com
Hi! Really nice video! Iam having a doubt in Solid Retention time and hydraulic retention time. The SRT how do we calculate it? Can we control it or we consider it as infinite?
Hi Elizabeth! You can control the SRT by manually adjusting the sludge waste rate based on the food to microorganism ration or MLSS concentration. Basic calculation for SRT is lbs/day of suspended solids in aeration basin divided by lbs/day of suspended solids wasted from the system
Depending on the configuration of the MBBR or IFAS system, phosphorus can be removed biologically in two (2) primary ways: 1) Through assimilation whereby Phosphorus/Phosphorus compounds are used as nutrient for biological cell growth, or 2) via anaerobic-aerobic combinations whereby Phosphorus Accumulating Organisms (PAOs) are readily adapted to absorb dissolved phosphorus and removed via solids separation. In option #2, the system is typically operated as IFAS (hybrid MBBR with MLSS) to allow the proper PAO activity and solids separation steps.
@@ssiaerationinc I work in Industrial Water and for many plants as a Field Engineer. The few MBBR startups I've worked on so far over the last year we have typically had to add Phosphoric Acid for Phosphorous as it is not that typical for it to be in the industrial wastewater to have good cell growth in the MBBR. In the beginning, I used to be so confused about the chemistry in understanding. But eventually, i understood it was micronutrients for cellular well-being and growth. Still, i appreciate the answer to the person who asked the question above in clarifying understanding either way.
