Gluestick Posted June 10, 2008 Share Posted June 10, 2008 Nawh!Same kit as was being used in all HM's nuke subs, cruise liners, brackish water wells in Southern Sain and best of all, Saudia.Anyway, I could live with a 4-5 year project re-cycle time.Bearing in mind that the feedstock was straight from the harbour, saline, and RO dumped 40% straight back, whereas MSF leaves serious deposits and RO only needs membranes replacing periodically, the HP pumps servicing and the sand bed filters renewed.Plenty of sand and plenty of energy!And all those lovely spares and service charges too!As Gordon Geko said, "Greed is good!"[:D] Link to comment Share on other sites More sharing options...

(ships and submarines). In high TDS, inshore, warm water they aremuch less viable. In particular, the Gulf has a high probability of oilcontamination which, as you know, is instant death to membranes. Coupled with aTDS of 45,000+ means your sand filters just don’t do it. Hence theneed for DAF units, flocculants, DMF units and cartridge filters all to get theright SDI for membrane inlet, plus of course the associated expensive chemicalpre-treatment, including knocking out the chlorine which is necessary to stopthe beasties growing in the sea water inlet. The bestrecovery ratio on sea water is c.40%, we are working on 38% so, at best, youare rejecting 60% of your inlet flow. Its better than MSF / MED admittedly butit comes with a very high risk and pre-treatment cost.Serious deposits from MSF ??????? Its brine, OK, its 60,000++ TDS but RO plants rejectbrine also, plus the reject chemicals, backwash debris etc. MSF plantsin particular and MED to a lesser extent are pretty bomb proof and don’t needany more specialised maintenance than is normally available in any powerstation environment. How muchbetter to use a thermal plant (MED these days) where your station overallthermal efficiency is high because you are extracting waste heat in the gasturbine exhausts that could otherwise be, well, wasted ! Particularly if youintegrate the plant with a back pressure steam turbine. Argue yourway out of that one!!!! [:P] Link to comment Share on other sites More sharing options...
Gluestick Posted June 11, 2008 Share Posted June 11, 2008 Joshing aside, Steve, there are still a lot of RO plants running/going in.Whilst this outfit do list MSF (in addition to other technologies), it does not appear as an app. on their ME project list.................here: Link to comment Share on other sites More sharing options...
powerdesal Posted June 11, 2008 Share Posted June 11, 2008 I agree GS, there are. My own major projects are a 5 migpd and a 3 migpd SWRO installation, both by CH2MHill, they are cheap to buy and hence offer short term (IMHO) advantages. I dont believe they are the "silver bullet" for water plants, at least not for 'less than clean' sea water.The plants on the list are, in the main, quite small, particularly in comparison with my recent 2 x 8 migpd MED units by SIDEM. Anything less than 5 million a day is small these days (hotels and ships apart). I consider my 3 migpd plant a bit of a side show. Link to comment Share on other sites More sharing options...

If there isn't, I think they should invent one.Come on, Gluey and Steve, knock it off, will you?[:P]Come out and play, or even fight, but don't be mean and keep it all to yourselves, hein?

Cat Posted June 11, 2008 Share Posted June 11, 2008 Anyway, speaking (as they were) about water...I'm awfully glad that it's just started raining again. I just love the rain, we don't get nearly enough of it, it cheers me up no end every time the sky darkens and the distant rumble of thunder makes the windows rattle.Oh look!

You'd best come in through your cat flap or you'll be struck by that lightning and it would serve you right for pretending you like the rain, OK?As for you, Frenchie, you'll have to bicker in English as the only remotely rude thing I can say in French is Va-t-en!
