As a newbie in water treatment, this channel is truly a blessing. Thank you! Entering my first potential wastewater customer today (2nd time coming to the customer site) Wish me luck 😅
Thank you for promoting the best parts of this trade we have found ourselves in, but Inquisitive and investigative and holding a positive attitude. This stuff can be tons of fun and rewarding. Some facilities are not very welcoming or receptive to inquiring operators but don't lose heart my fellow Operators.
Dude, you are inspiring. Your explanation is spot on and easy to understand. What a wonderful resource for wastewater operators and the other folks we need to "get it" when we need their understanding for support. Thank you.
Great video. We run the same disk thickener at our plant. Problem we are having is we use a rotary lobe pump to pump the thickened sludge to our digester. If the thickened sludge is too dry we tend to cavitate the pump.
You did very well, just one thing you should have done a Filtrate samples to check the capture rate to ensure you are not sending more solids back, you are clear and good data.
We got that dried curse delivered, stored in moist mixing room, and a pain to clean without chlorine... Then, I would run many bags up to the sbr's for daily use. It was also horrid in the eyes.. The wind would blow it around while we dumped it.. I hated that stuff.. Thanks for the memories.
I admire your guts to handle the sludge. 98% of the people I know would scream if they even saw it. I did sampling of it, many times. Weigh, cook, re weigh, record, do another
@@WastewaterOperationsChannel I have a case where anaerobic pellets are fully coated, encased, leading to anaerobic sludge washout by flotation from their own gas. I can't come with a reasonable explanation. Surface tensioner has been my first thought but Polymer dosages have been triple checked reduced without any benefit :/ Anyway, great channel thanks you for taking the time to answer.
Very helpful with optimizing I work in water treatment at a plating company and I had no idea that my water was so cloudy because I was using too much floculent and it’s really important my water is as clear as possible because we evaporate it and the extra particles mean I have to empty and clean the evaporator tank more often, and we have around 10,000 gallons of built up waste sooo can’t exactly stop processing very often. So that’s my long way of saying thank you you gave me the things to look for and try. P.s all I got was a crash course and told good luck at my company when I decided to take over water treatment have been doing it for less then a week
Anthony Keep up the good work. Lots of folks end up kind of on their own but what makes the difference is our willingness to say “I don’t know” and learn something new.
First off, Very helpful and insightful video. Secondly, What kind of dry solid content are y’all getting? Using a screw press and velodyne mixer, we hover btw 16%-20%.
Excellent video!! Don't remember all the specifics of the polymer we were using. But it worked great! However, keeping it properly dialed-in to prevent over or under dosing was a nightmare.. Flows and sludge characteristics could fluctuate a lot, and rapidly. The process ended up being rather attention intensive, regardless of all the automation. (Retired operator, City of Hayward, Calif.)..
I'm just curious to know what is the gallons of polymer per hour are added to the sludge feed rate in gallons per minute. Ours is about 4.5 gallons of polymer per hour for 150 gallons of sludge per minute.
Iv been thrown in the deep end and left to operate a centrifuge with only a days training... desperate to learn as much as I can about this so I don’t mess up!! Need the cake to be coming out dry so I can load more in the wagons.
@@WastewaterOperationsChannel what’s your email address? After a week on it tweaking around with settings I managed to get good dry cake being produced but still don’t have fully clear centrate... cheers
I accidentally spilled a large dose of swimming pool flocullant on a well. I pump all the water out. The well had only 1000 liters and I spilled a liter of a swimming pool flocullant ,aluminium hydrochloride. It as been 4 month now. The well is on mud. Can I use the water? Is it still dangerous? What happened to the flocks? Are they still toxic? Did they dissolve with time? Thanks.
@@WastewaterOperationsChannel thank you for the quick reply, one more question! Polymer is injected how many times in the whole process? Once obviously in this video when the two sludge streams are combined, but isn’t polymer also added earlier in the process?
I'm waste water Operator (Etp operator) ,I wnt job another country,am from India and I have passed the degree in waste water training treatment, Oxford institute since 2018
Reda thanks for watching and for the question. I wish it was an easy thing to answer...the answer is it depends. Processes like the one in the video are primarily thickening and use lower amounts (1-5 lbs per ton of material being thickened) Dewatering of digested sludges require much more (10-60 pounds per ton maybe more)
Fatih Thanks for reaching out! This specific Polymer is a Solenis product. As I stated in the video there are an infinite number of combinations and prices for polymers. So what we use and pay can be completely different than everyone else. If your interested further I’d suggest finding your local SNF and Solenis rep if you’re in the States. If not brands and corporations names will be different.
The polymer emulsions leaves the water murky when there is excess polymer in the solution. For most of these polymer products, a 5% polymer in water solution will be a white/cream color and very thick. The clearer the water, the closer you are to the correct level
Hello @@csl1315 , I would be so grateful if you could share some knowledge about these polymers, like their origins ( the raw materials) and some of their names I mean the chemistry behind them, if not please be kind to gide me where I can find those
@@csl1315 hi sir how to achieve clear water using polymer? And what is the best ph level before using flocculant? I work in waste water treatment metal recovery.

i don't work with Wastewater but now i want .... congrants dude... amazing video
Nicely described with full of clarity. Thanks.

Thanks WaterDude!
Wow! I get the gist of this, I'm studying to get operater certified, and this is helpful.
Gonna share this with our press operators. I know they can get some insight out of this video. Thank You !!!
Great video.

Yes viscosity can be a real problem when pushing high concentrations of solids for most any pump.
You did very well, just one thing you should have done a Filtrate samples to check the capture rate to ensure you are not sending more solids back, you are clear and good data.

Very informative video.Kudos
Hope seeing more practical vlog like this.
Really great clear video and nice to see some of the practical and theory in one video.
Thank you so much for those words of wisdom at the end.
Thanks for watching Alex!
@@WastewaterOperationsChannel did you ever encounter anaerobic sludge pellets with a coating all around them due to too much polymer ? Great content
Great question arkama
I don’t think I have seen that
But if you found enough poly to coat the pellets I would think you’d want to reduce dosing
@@WastewaterOperationsChannel I have a case where anaerobic pellets are fully coated, encased, leading to anaerobic sludge washout by flotation from their own gas.

Nice and informative video. Keep’em comin.
awesome video! I operate a DAF system and I think it might help in the treatment process as well, THANKS

cool video!
Very useful information. universities provide only theoretical knowledge but this type of video gave pretty good practical knowledge thanks a lot!!
Thanks for watching jd!
Hello. Great videos. Would you do a video on ammonia in digestate? How do you handle high levels of ammonia?
Justin
Thanks for watching
I’ve got some ideas on nh3 removal…stay tuned!
Hi. A really great video. Thank you for good explanation and separately for music!
Hi I want to ask, ever you tried to apply flocculant in a heavy mud? and measure the SG?

(Retired operator, City of Hayward, Calif.)..
Awesome video. Can you tell me about the mixing valve ? It’s a NRV or check valve with weighted arm ?
It’s a mixing valve
Kind of like a check valve, but the intended purpose is to add a bunch of shear right at the point of polymer injection.
Very Informative Video..
Good stuff! thanks
Very interesting Vedio and very attractive way of educating 👌.
Nice video! Im working on a wastewater plant in Finland 🙂
Very cool, thanks Jonas
What kind of plant?
How do you say B.O.D. in Finish?
I have job
I want job ,?
Great video man, I am looking forward to you next knowledge sharing. Thanks a lot for making these great videos and thanks for sharing

We use a centrifuge at my plant. Its interesting to see a different method. We get roughly 20% but there's a huge upfront and energy cost.
20% efficiency ???
@@leahfrances2229 yup. 24% with the right polymer.
I'm just curious to know what is the gallons of polymer per hour are added to the sludge feed rate in gallons per minute. Ours is about 4.5 gallons of polymer per hour for 150 gallons of sludge per minute.
So what is the brand of the polymer?
This polymer is a Solenis product
hello
i work in a paint shop plant , what is the diferent of polymer and detackification, i have problems about sedimentation
Hi sir how can i make water flow in filter press flow smoothly.? Because im having trouble the water didnt pass through it always stuck.

Why overdosing floculant leaves water murky?
The polymer emulsions leaves the water murky when there is excess polymer in the solution. For most of these polymer products, a 5% polymer in water solution will be a white/cream color and very thick. The clearer the water, the closer you are to the correct level
Btw I'm a QC lab technician for one of these major polymer manufacturers

That’s a bit of an oversimplification but yeah!
