gladken, Get the full chemical analysis of the FO from your vendor. After doing a combustion analysis, this will tell you what the ash is and how much is generated per pound of fuel combusted. Better yet, get the vendor to do it.
Hope this helps.

ashgar, One question; Without bridle blocks, How do you clean and maintain the bridle without shutting the process down? Remember, down time is money!
Hope this helps.

gmorin, volume flow is volume flow (cfm). Cut off the flow, volume goes to zero. Convert gas volume to liquid volume and this is the volume you lose.
Hope this helps.

Volunteer, You may want to take a look into Ultra-filtration/RO. Based on your flow rate, you're only looking at approx. 3.5 gpm which is well into the range of smaller UF/RO units. As for crystallizers, this is awful far down in their operating range.
Hope this helps.

phrex, I didn't mean to flog you on this one. When it comes to common sense, I have an old saying, "If common sense were a common commodity, the world would be a utopia". With that said, you've gained some valuable experince and the value of clear, detailed, and specific specifications and...
Procman, In the interest of saving drafting hours and ease of making revisions; I prefer the simple, "From Dwg. xyz" or "To Dwg. zyx" (both based on direction of flow). When tied to a specfic Equip. No., when revisions come down the line over the years,which they will, it makes revising the...
roker, There is standard piping layout design that has been used for years to approximate equal flow to nozzles in exchangers. The standard arrangements are based on the number of total inlet nozzles; less than 4, 4 to 6, more than 6.
In your case, 2-10", manifold: 30" with two 10" nozzle...
ghamsa, Pick yourself up a copy of Fisher Controls, "Control Valve Handbook". It will give all the info you need to size for slurry, liquid, vapor, gas service for pressure, temp., flow, and level control.
Hope this helps.

Tomfitz, You can utilize the Pump affinity laws to check the comparison. Better idea, demand the Manu'f. pump curve for the pump in question. No curve, no problem, the pump doesn't come into the plant.
Hope this helps.

dkf, There have been some minor hydraulic improvements in impellor design and at the suction impellor eye(due to CFD). The real cost savings have come about in the development of Hi-effciency motors and the implementation of VSD's.

SanEnr1, The first place to start is to get the sludge characterised. Is it hazardous or non-hazardous? And if hazardous, what are the hazardous components-concentrations. Are the pathogen levels high enough so that it cannot be used in land application? Once these types of questions are...
Timbl, When you say "weir" what kind of weir? Each type has it's own flow vs head characteristic. Do a web search for Isco. They are the experts on open channel flow measurement.
Hope this helps.

Rollerblades, Wood is derived from a carbon based life form. Therefore, the chemical formula is: carbon, hydrogen, oxygen, nitrogen, and a multitude of other elements, mixed-matched-combined into a multitude of organic and inorganic molecular structures that when combined make wood.
Remember...
luizmi, If the pump is properly bedded, anchored, aligned, balanced, and the piping is not forced onto the nozzles (except in cases of coldspringing) there should not be a problem with vibration. If there is, something is wrong with the pump or it's installation. As for flexible connections...
