Perth has two desalination plants with combined capacity of 150 billion litres of water a year
Rhian,
In realistic terms that translates to 450 Billion litres of brine from Perth alone. Add to that the many, many, many times more outflow from plants around the world, added by other massive pollution from ships & industry etc.& it's not rocket science that the oceans are acidifying at an alarming rate.

Your earlier post made two claims – that desalination “is only an option for small scale operation up to 300-500 Kl/day” and that there is a “huge blob of brine in a river in Perth WA” because of desalination. Both are wrong.

Both are wrong.
Rhian,
I did say I "believe" re the blob as I clearly recall reading & hearing about a huge blob of brine from a Desal plant going back & forth in Swan River some years back.

You obviously have something to gain from portraying desalination in a more positive light than it really is.
A 100Kl/day plant running off an 80Kva genset requires 180-200 Diesel/day alone.
No Green power can run that for a day in the first place.

Replenishing groundwater & dams are a far more environmental solution. Also, less waste will help as well.

Your memory is clearly faulty. Or, perhaps can you explain how there could be a salinity problem in the Swan River caused by discharge from a desalination plant, given that Perth’s two desalination plants are many miles from the river and discharge into the Indian Ocean.

Yes, desalination in energy intensive, but both of Perth’s desalination plants use renewable energy, which has low environmental impact and marginal cost.

I have nothing to gain from portraying desalination in a favourable light. My only vested interest in this issue is that, as a Perth resident, I want access to reliable, affordable high-quality potable water produced in a sustainable manner. I am happy that the Water Corporation has taken measures to deliver this.

More evidence that SusPopAus spruiks opinion based junk (social) science word salads masquerading as credible hard science analysis, without evidence while ignoring or omitting other factors....

Mr Saunders, have you ever been to a Tanton or TSCP writers' workshop?

You analysis resembles your mate running around Crikey comments section Dr Smithy who shoots messengers, avoids detail, makes BS claims to dog whistle young people while running protection for ageing boomers, fossil fuels and power?

Too easy when talking points are repetitively platformed by RW MSM & social media, starting with Fox News employing chums of Tanton's reporting to the top, hmmm?

Rhian,
Well, it may not have been the Swan but I clearly remember reading about some inlet near Perth having a brine blob from a desal just moving back & forth in the tide. I've tried to Google it but no luck.
