    Viscious Cycle - Retention Strategies Part II

    I could take a wild guess - are you in Alberta? It's crazy alright - my companies trying to compete with a whole other sector (oil & Gas versus Pulp & paper). They've been trying their best but still people leave. All I can offer is hold on tight - the ride isn't finished yet.

    Need help with compound

    jrpengr: If you can isolate I believe you can acid wash with pretty much anything you want, **then flush** and return to service. I.e. rydlyme, sulphamic, HCL. We clean our density meter with rydlyme and flush. Our system is partly potable water. Pulpmill so about 10 l/s potable and 950 l/s...

    Recent graduate with poor GPA, what do I do about my resume?

    Senseless wrote "truth is....anything less than a 4.0 is result of knowingly and purposefully diverting attention away from your academic life. Doesn't matter if its drinkin beer, chasing women, working, video games, drugs, wife, kids, sports, or just plain laziness. Its a choice!!!" I'd...

    Recent graduate with poor GPA, what do I do about my resume?

    My GPA wasn't all that great (in fact pretty horrible) - I never put it on the resume and had no issues. In fact one interviewer asked about it and I told him my GPA and he was happy I wasn't the brainiac type. He figured that straight A students had no life and therefore were socially inept...

    Need help with compound

    Went back to the manufacturer and it turns out sulphamic will disengage the inhibitors/buffers in the Rydlyme. Thanks Unclesyd.

    Need help with compound

    I'm more curious then anything since I want to make sure the system lasts. I do not know what the inhibtor is - the product is Rydlyme if you've ever heard of it. The set-up allows intermittent circulation of rydlyme through the system to remove the lime or Calcium carbonate build up. When...

    Need help with compound

    We use a inhibited hydrochloric acid to remove lime scale deposits in our lime slurry system. Once in awhile operators have used sulfamic/sulphamic acid in the system as well. I'm trying to figure two things. Something is gassing off to discolor surrounding stainless and also it corrodes the...

    Severance bonus

    I say keep your mouth shut - wait for the bonus, then leave quietly. I certainly wouldn't try and ask for it if I left before it was handed out and EddyC is right - you are risking a bad reputation but that depends on how much they liked you, how much you did for them to get the bonus and how...

    Hydrated Lime Slurry Pumping

    Does anyone have any reference material for pumping of lime slurries. Things like: 1) Line velocities (I've read around 4 to 7ft/s.) 2) Densities for pumping 3) Properties of lime slurries at various densities (viscosity etc) Does anyone have any actual testing performed that can be...

    Cleaning large running sewers

    The mill I'm at has a gravity sewer system which flows through 1200mm pipe and through various distribution boxes. Flow rate of 900 to 1100 l/s. Flow rates during maintenance days are around 50 to 300 l/s. Temp is 50 to 60 deg C To avoid costly bypassing is there a way to clean the...

    Diaphragm Pump Problems

    I can't tell you much about whether we like the pump or not since I don't work the area but we use a Allis-Chalmers - F4H1+731 - 6" X 4" X 8.5" for our Dregs transfer from green liquor clarifier. Checking maintenance history it appears / semi / yearly PMs the odd change out etc so I would...

    Industry Standard for Industrial Clarifier or Centrifuge?

    Furthermore we have had pretty good success with our GL&V clarifiers so you might try them.

    Industry Standard for Industrial Clarifier or Centrifuge?

    We are currently investigating centrifuges for sludge dewatering in our pulpmills wastewater secondary/primary treatment. We have come to the conclusion that there are many light duty decanting centrifuges and possibly 2 heavier duty suppliers. Alfa Laval and Andritz. These are the two we are...

    Coiled HPPE vs HPPE lengths with Weld Connections

    I tried heavy wall coiled 6" pipe... about the biggest you could get to save on fusion machines and operators during a directional drill. I would go with straight sections next time. It was a pain in the ass. I would suggest for anything under 4" use a coil. Anything over (and including...

    Anyone using Biomass boilers?

    Try www.tri-inc.net They have a system for turning biofuels into syn gas at a cheaper capital cost than most. Don't know much about it but we were investigating it for Hog (bark) fuel and our Black Liquor. Good luck.

    Diffuser scour situation

    We have a pipeline and diffuser for our effluent and the cover has been washed away. The divers are recommending a method that I see as being very costly. Anyone tried to replace cover on a pipeline or diffuser n a river? How did you do it - and did it work/last?

    Home Remodel

    I plan to remodel my house next year and I would like to do the calculations myself. Basically I want to knock out a load bearing wall (Larger than the typical opening) and raise the roof on an addition so that I have one continuous room. (kitchen / Dining / Entertaining) Since I'm only a...

    To do list

    I use a program on my PDA & computer called Trenotes. It's sort of like using outlook tasks but with more power. The main feature I liked was the ability to have sub tasks and auto updates for the main tasks. I.e - I have a main project with 10 subtasks... when I complete all the subtasks the...

    duty/assist/standby rotation of pumps

    First off it makes logical sense to have the VFD on the Assist pump, since it will save you the most energy and be varied the most. I would suggest the other VFD doesn't really matter where it goes. If the duty (100%) pump fails then the spare is kicked in at 100% No VFD needed. If the...
