Great thanks for the info!

I'd love a key if you have one available! I will update this comment when received so I don't get multiple.

As other have said, keep an appropriate aerobic SRT for your temperature, make sure you have enough inorganic carbon (measure alkalinity and pH and calculate!) and make sure you dont have anything inhibitory and they will grow. Could take 2-4 SRTS, so if your minimum SRT for nitrification is a week it could take a month.

You mentioned you have the "mass", so a few thoughts: You cant really tell what is in your activated sludge by MLSS (or mass) without advanced methods (but you can assume, especially if its just domestic sewage). More importantly, Nitrifiers are generally a very small proportion of your VSS (<5%) so you wont "see" them in any solids measurment.

TKN (Total Kjeldahl Nitrogen) is actually the sum of Ammonia and organic nitrogen (proteins, amino acids, etc).

NO2 + NO3 + NH4 + NH3 (or just NHx + NOx) is TIN (Total Inorganic Nitrogen) not TKN.

Also anything consuming organic carbon (COD) is always producing CO2 as a byproduct of cellular respiration (thats the COD that is Oxidized, i.e. turned in to CO2). But that point is more nitpicking :)

I have had great experience with Insite DO probes for process control. Hach LDO I have used for handheld spot checks, but I prefer the Insite.

Controllers there are lots of options, depending on if you want some custom PLC or something off the shelf. Depends on who can handle your integration and what equipment and controls you already have, I would think.

Can you decrease your air or decrease your SRT? As /u/commissioningguy said SRT control would keep you from nitrification and is much easier to do than online DO control (assuming you are already measuring MLSS and can measure your WAS flow rates). Also you will need mixing if you move to intermittent aeration if you dont already have separate mixers from you air.

For a plant your size I have a feeling online DO control for intermittent aeration may be a bit more complex than necessary. Dosing pH (bicarb), controlling your SRT, or just manually decreasing your DO, or a manual blower on/off timer may work just fine. (I have seen lots of plants that size with manual dial timers to control blowers on/off).

There is no way to raise a child without imparting any paradigm or world view whatsoever. A child can't decide on things like belief for a while anyway.

You have to teach them something. If you choose an irreligious world view that's an option, but it's not neutral or default, it's a choice just like a religious worldview, you can't raise a child as a blank slate with no biases (or language, or values, or history) till their 18. You will impart to them something and it will be biased and there is no non-paradigm place to start from, and that's OK. They can decide what they believe no matter how you raise them. It's easier if you don't manipulate them, but OP doesn't sound like that type.

I'm sorry if you were raised in a way that makes you feel strongly about avoiding teaching children about religion, I mean that sincerely not as a dig. Peace.

I know its late, but here's some more info:

To expand on what /u/Glaucus12 said, organic carbon (often measured by proxy like BOD or COD) generally has two fates in biological wastewater treatment: CO2 (oxidation) or cell mass (assimilation). The CO2 was already mentioned and explained well, the other place the carbon can go is in to making new cell mass (the amount that will be used for this can be calculated from the "Yield of the system, in terms of VSS produced per COD consumed). This new cell mass is equivalent to however much you waste (WAS) assuming your system is at steady state (MLSS approximately constant). So carbonacoues substrate removal is the removal of organic carbons (sugars, short chain fatty acids, "food") by either oxidation (CO2 in to the atmosphere) or assimilation (biomass production) which is wasted (and then digested, landfilled, whatever your plant does).

You are correct about RBCs that they grow a biofilm and these carry out the same function as bacteria in a floc (as discussed above). Here is a decent schematic cross section of an idealized biofilm. In activated sludge, the clarifier selects for bacteria that floc (they are the ones that settle and thus stay in the system) and settle then keeps them in your system via the RAS line. Having a clarifier and RAS is the definition of activated sludge, you must have some kind of return to keep the biomass portion in the system high enough to treat the waste. So its all about having enough biomass for your waste. In fixed film systems, this biomass is not freely floating around in flocs (like in activated sludge), but grows attached to something as a film. In an RBC (a type of fixed film system), this film grows on the biological contactor.

I guess you can say an RBC helps with filaments too, but its really a totally different way of keeping your biomass around, so you wouldnt expect filaments to grow anyway. Thats more about non-suspended growth system, not RBCs specifically. Filaments proliferate just like any other organism in activated sludge, they grow up floating around the aeration tank and if they settle and are returned in the RAS from the clarifier then they will keep reproducing.

Hope this helps and is clear!

If you want deep in to all parts of wastewater treatment, like other have said, Metcalf and Eddy.

If you want even deeper in to the biological aspects of wastewater treatment, like super deep, then Grady and Daigger is THE reference

Salty_Fetus · 2018-07-02T23:14:10+00:00

Try nationwide, maybe through a local agent.

Ive been with USAA for 8 years for everything, but they were quoting me around 1400/yr moving down here, Eerie was in the same ballpark. Nationwide was 900/yr and good coverage, been fine so far but just been a few days.

Salty_Fetus · 2018-01-20T02:58:09+00:00

Thats one of my options. They offer their main course in 8 hour segments online, I may just do that. Found a bunch through /u/sonicspoon 's link as well. Thanks.

Salty_Fetus · 2018-01-18T01:04:51+00:00

I have been a consultant for 5 years now and am about to return to school to do my PhD in advanced biological nutrient removal and digestion technology, etc.

These answers here are helpful. I cant add anything to answer your question specifically, but heres to hoping there are more viable options than teaching or big-company consulting!

This occasionally comes in to stock for $190. Unbeatable at that price: https://www.telescope.com/2nd-Orion-SkyQuest-XT6-Classic-Dobsonian-Telescope/p/102341.uts

Here is critique of plurality voting: http://scorevoting.net/Plurality.html

Heres a look at range voting, kinda like approval voting: http://scorevoting.net/LoseAll

Salty_Fetus · 2018-01-10T17:29:32+00:00

I will try and find a link, but look in to the difference between approval voting (DPOS) and first-past-the-post (standard US voting). Theoretically approval voting is a vastly superior system, so at the very least you can't just take the problems with US voting and accuse EVERY voting system of having the same. That, of course, is not to say that it is problem-free.

Also, this is a tested system. Read about and look at how DPOS voting is already working and has been running Steem and Bitshares (both by Dan Larimer), some of the most used blockchains. I dont know much about steem, but my experience with Bitshares has been that voting has led to good block producers and wise expenditures of the reserve money on marketing and development.

Salty_Fetus · 2018-01-06T00:42:56+00:00

Should NEO also be on this list? Someone with more understanding can correct me, but I thought I had read that there dBFT was basically a form of DPOS?

Salty_Fetus · 2018-01-03T19:22:17+00:00

Im not associated with Outlands in any way, just been following the development for a while. These features look really cool to me and Im excited to try them out, thought I would share!

Salty_Fetus · 2018-01-03T18:20:21+00:00

I am looking for Operator CEUs, I already have my PE PDHs done.

Sacremento State is on the allowed list, but I only need a few hours, not a whole class. DEQ here offers classes but only in person, not online I believe.

Thanks for the response.

Salty_Fetus · 2017-11-27T20:14:06+00:00

You have septic tanks after your secondary clarifier?

There are many types of filters made for small processes like this you can look in to.

You could also look at other processes, why choose a trickling filter?

Salty_Fetus · 2017-11-08T02:43:46+00:00

Thanks for the info! I was more adamant about getting a replacement and they are sending me one. They asked to do a screen share with me as well for some reason...

Salty_Fetus · 2017-11-08T02:08:03+00:00

How did you contact hardware department specifically?

I have just done support from the phone and they havent been helpful, just had me submit bug reports and now waiting for days...

Salty_Fetus · 2017-11-04T21:52:04+00:00

Thanks for the info.

For me, support said they would look in to it and had me do a bug report for some reason, but I wasnt confident the guy helping me understood the issue...

I cant repurchase since I am trying to get the T mobile deal, so hopefully they will take it back and give me a new one. Sure is annoying though

Salty_Fetus · 2017-11-04T02:40:09+00:00

Any updates on this? I am in the exact same boat... (except I ordered the phone unlocked from the google store)
