Any water or Wastewater guys here?

Yeah, its a program that allows you to control a PLC or VFD remotely, also it allows you to have sensors basically anywhere you want them to control temps, and pressure. Its great for pump stations because it allows you to control a place without physically needing someone there.

It is basically for monitoring but it also allows you to remotely control the instrument as well.

 

That's awesome I will have to talk to my instructor about it tomorrow..

 

I'm mostly on the pure side. Actually I'm the one who gets to talk to the FDA when the show up. We are in a GMP environment, so things have to be up tight. Its a PITA, but its always interesting.

 

A lot of records and paper involved im sure.

 

it is interesting stuff. ill see if I can grab a screen shot of our system to give you a basic idea

 

Right on brotha

 

Yeah, between pathogen reduction methods, soil science and dewatering with polymers and centrifuges, there is a lot to get your head around.

 

Indeed. For a 15. Min. Temp. Calibration, its about 30 min of paper and computer work.

 

This is our sludge receiving from our dewatered bunker to our furnace. It allows you to check pipe pressure, lube pumps, bunker and hoper levels, and which leveling screws that are operating. also, you could click the words (running or stopped) and switch them on or off depending on what was going on within the plant. tracks everything you need to know.

 

You will work with the state, so yes, be prepared for lots of paperwork.

 

I can believe that, we have to take samples every 2 hours and record all the data, 24/7 365

 

yes, you also need to learn very fast that polymer is extremely slick if its wet. Did your plant have good luck with their centrifuges?

 

Yeah, we worked with centrifuges at several facilities as both permanent and temporary installations. For the most part, once the polymer was dialed in we had good success. The up front capitol spend was pretty significant, but high trucking and landfill tipping costs often made it pay off pretty quickly. As for polymer, I've seen a few nightmare polymer spills in plants that just about broke me. There isn't enough water in the world to clean it up...

 

Were one of the few plants that runs a centrifuge. Several people we have met at WW conferences swear against them and said plate press is the best way to dewater sludge. However, I disagree. We have had good luck with our centrifuges and they require very little maintenance for how much they run.

 

I've worked with chemical treatment and operational optimization of CWT, boilers, and waste water at refineries.

Water is a niche industry but an extraordinarily important one. You'll always have a job, that's for sure.

 

The facility I work at has its own waste water treatment facility that I have to monitor and sample. Also deal with large air compressors, boiler, cooling water systems, and everything else in the facility lol. We run DeltaV

 

I won't bore y'all with the chemistries of polymers/coagulants, but many are flocculants: coiled molecular chains that uncoil & expand when exposed to water and attract solids and other muck that's in the water. The good news, like skisaibike said, once you have the correct ppm dosage for your application, they work like a freaking champ. (Obviously if you have too much or too little, you won't get the clarification that you need among other potential problems.)

Unfortunately, because water causes floc to uncoil, it seems you need about 100lbs of kitty litter, another 100lbs of pig mats, a shovel, and a whole lot of curse words to clean up a gallon of even semi-wet polymer.

 

I am appointed to sit on a Board for a municipal authority, not too big,
30-40,000 "customers".

Starting a substantial upgrade at the plant, dollars and millions of gallons treated.

Under a few consent orders, DEP, EPA

Never a dull moment

 

Our waste water company is made up of board members as well.
