the desalination plants on the sea shores will dump the chlorides back in to
the sea. That is no problem.
Salt% will be equilibrium in the Sea in a few minutes.
Also, theTHICKER BRINE will be better starting material for Soda /Alkali
plants.
What IS a problem? The anaerobic bacteria in the Septic Tank will all die!

the sea.
think of the whole lot of problems and diseases we are having because of
scarcity of water. an experimental initiative can always be taken. technology
will find solutions to any problems that crop up. salty water can kill many
bacterias and deadly viruses.

I do not think that is such agood idea. Where will we dispose the heavy
chloride content water then? Into rivers? It will only add to the increasing
pollution of river streams. Also, too much chloride can prove detrimental to
the fresh water aquatic life.

I'm uncertain where the notion of desalination (which is expensive) fits into

treatment can follow to further remove BOD and other polluting factors. The
water salinity would tend to make the oxidation more difficult. Certainly
ideas which centre around smaller-scale dry oxidation need to be rigorous in
achieving some sterilisation. The most useful ideas are through using
bio-remediation. This can achieve (re)cyling of waste as fertiliser through
sterilisation and also 'stabilising' the waste so that chemical decomposition
can make the nitrates fraction (ammonia conversion) available for plant
up-take. > To: [EMAIL PROTECTED]> From: [EMAIL PROTECTED]> Date: Sun, 11 Nov
