Waste Brine Evaporation Systems
DON'T TIP WASTE WATER DOWN THE CREEK!
AVIVAPURE™ has Permits from several Water Authorities to discharge the waste water (less than 200kg of salt) from Reverse Osmosis plants to the sewer. We can also obtain specific Permits from Water Authorities for larger discharge rates and for commercial sites. If you have a sewered service, you can apply to your relevant water authority for a permit for your plumber to make a connection to the sewer.
AVIVAPURE™ will not install any plant that could discharge any concentrated waste to creeks, rivers or lakes if it's potentially harmful to the environment. If you have a spare dam or some space, you could use the waste for aquaculture. Some farmers grow barramundi, mulloway, trout, red-claw, brine shrimp for fish food; seaweed, etc.
One farmer with a desalination unit draws feed water from a bore and discharges the waste into a nearby lake. The waste has a lower salt content than the lake. All the waterbirds congregate around the water discharge pipe to swim in the purer water.
Evaporation Ponds
Some users discharge the waste onto large, shallow, black-plastic-lined evaporation pans. When it is concentrated by the sun into brine, the salt crystallises and can be collected and packaged as a gourmet salt product, which provides extra income.
