The Desal plant ....thoughts??

[Tyke 0]

Wondering if anyone has any thoughts or concerns on the desal plant and what affect it could have on the local waters??We were fishing close by the other day (but not inside the designated no go zone)The water was quite cloudy,nearly milky.Everywhere else we fished was crystal clear.Could the outlet be stirring up the water??Also noted that we saw 4 boats run through the no go zone!

Considering the "Intake" and "Outtake" lines haven't been tapped I think your concerns are premature.

Hopefully none, but I have a feeling it's going to bugga things up

JackFlicked through a Uni of NSW paper recently (Roberts/Johnston/Knott) reviewing worldwide studies on desal plant impacts.The short version - many local variables of course, but you are talking salinity levels above normal generally extending no more than a few hundred metres, max. Depending on the type of plant, chemical discharge can be a consideration though.Port Stanvac should not be an issue on balance, but the Whyalla cuttlefish may start curling up their toes(?) if the boffins get it wrong with that desal...

I'll sit back and wait-reckon its still a tad too early to jump the gun

I thought it was doing limited runs already??Guess I'm looking for something to blame.

Dumping of tons of concentrated brine + dodge tides = not good,no matter how you look at it.:ohmy: :ohmy:

After speaking with a fisherman friend who knows a little about the subject of water, any concerns I had about the effects of brine being released have been calmed.

The main concern is going to be the harsh chemicals used to flush out the system

Fishie - desal technology is evolving, so fingers crossed;3.3. Impact minimisationDesalination technologies have evolved rapidly in recent decades. In a 1991 review, it was found that over 65% of desalination plants relied upon thermal distillation processes referred to as multi-stage flash (MSF), a process which yields high temperature brines, and greater atmospheric pollution (Al-Mutaz, 1991; Morton et al., 1996). Historically, MSF plantshave been popular in the Middle East where rich fossil fuel deposits have meant cheap energy is available (Tulharam and Ilahee, 2007). In nations such as the United States and Australia, these methods are rapidly being replaced by membrane based methods of desalination such as reverse osmosis (RO) plants, which tend to have lesser thermal impacts, but produce saltier brines (Dweiri and Badran, 2002; Tulharam and Ilahee, 2007). Developing pressure exchange technologies may assist in reducing the salt content of RO brines (Campbell and Jones, 2005). By reducing recovery rates (i.e. reducing the amount of freshwater extracted from a given volume of seawater), RO plants may improve energy efficiency, produce less salty brines, and reduce the need for pretreatment of intake waters with chemicals (Campbell and Jones, 2005).Hopefully this will have a positive outcome in terms of a reduced need to put nasties through desal systems for flushing :whistle:

Let's hope so Kon .... thanks for enlightening me
