We've been demonstrating the reduction of BTEX, MEG and THC on condensate coming from the piping of LNG to shore from the North Sea - but not sure if this is an issue in the United States - as far as the level of contaminant and the ability to discharge to ocean or river (EU Regs). Can someone...
Good Morning - looking for wastewater treatment firms currently working on treatment of leachate lagoon water from tar sands oil extraction in Alberta and Saskatchewan Canada.
Need information on current treatment regimes.

I'm looking for a good commercial greenhouse growers forum - need to ascertain average heating cost, using NG/propane or electric heat for commercial greenhouse growers during the winter. Anyone have a good forum that has national participation?

Hope you all are looking at the Interium Report that just went in for final approval - especially those of you who work in aquacultural rearing or agricultural wastewater treatment - as this is going to have some major impacts on federal hatcheries as well as private rearing facilites - as well...
Were working on a design for revamping existing oil-refinery wastewater system in Eastern Europe - one of the aspects is the storm water. Equals 36,000,000 gallons in 24-hours. The oil/PAH/THC/Aromatic is not of issue for us to remove - but there will be heavy precipitate at the end of the...
Heard that an American company got the contract with China to treat the water from the benzene spill at the freshwater plants - anyone know who got the contract?
Hello Everyone -
I'm looking for a company that manufacturers/provides coagualtion tank scrappers - the slow scrapper/paddle type that scraps the coagulated oils off the top of the water and to discharge pipe or weir.
Any referral to company or website would be much appreciated.
Thanks -...
Recent tests in Aberdeen Scotland by Codyne Limited have prove n the ability to coagualte emuslified oils from oil barge washout and bilge water to levels beyond oil/water separator (10,000 mg/l down to 5 mg/l on THC - less then 1 mg/l on aromatics) - allowing for direct ocean discharge...
Hi -
Can someone advise as to the typical chemicals added during the production of produced water? Primarily, are their surfactant residues in the produced water - and if so - is this from additions prior to DAF or oil/water separation filtration or where in the process?
thanks
Hello Everyone -
We've been working on the treatment of produced water coming off the oil rigs - reducing THC/COD/Aromatics/TSS below 5mg/l to meet the 2007 discharge regs for the North Sea. We've done that and are working with the various oil companies to take the technology onto the rigs or...
Can anyone advise where I can purchase large quantities of #6 (1/8th inch) course or fine thread teflon read-thread rod? Tried US Plastics and FABCO - but they don't have it.
Any other rod is ok - but has to be non-metallic and work in immersed temperatures up to 185-F.
Thanks

I am trying to find out what engineering changes are being adopted or discussed to address the new EPA rules concering CAFO's and AFO's (confined animal operations - such as hog/swine production). The new rules throw out the old 24 hour-25 year storm event, reducing manure and lagoon...
For those of you who build hog barns and manure lagoons - with the new EPA guidelines coming out - calling for "zero discharge" what if any new technologies have you found, new construction designs, are you having to implement to meet the new permitting regualtions?
Other then...
Another question - we utilize a dehumidification system to reduce high humidity - control mold/fungus growth in greenhouses - then take the humidity and turn it into heat for both the ambient air and as supplemetal hot bed heat. Cut's down natural gas/propane use by 45% - other then the projects...
Does anyone know if lanthanum chloride, when applied to remove (flocculate) phosphate from irrigation water can be broken/utlized by plants? Have used product to reduce/prevent algae blooms in lakes and ponds, but can't seem to find any literature that states grass/plants can utilize the...
