COULD SEWAGE BECOME OUR SOURCE OF DRINKING WATER? – The House


Assets are throughout us.

However hardly ever will we consider water as a useful resource particularly when contemplating wastewater.

But for over 50 years, Veolia, a utility firm has been changing wastewater into ingesting water in Windhoek, Namibia.

A tall order it could appear.

Nonetheless, come to think about it, water constitutes over 90% of wastewater.

If that’s the case, why can’t we go the additional mile to reclaim it?

WASTEWATER TREATMENT PLANTS

Image this…

The principle wastewater therapy plant in Nairobi receives over 160 cubic metres of wastewater every day.

That’s 160,000 litres of wastewater each day.

This converts to over 58 million litres of wastewater yearly!!

In fact this water is loaded with all kinds of pollution…

From microorganisms to fecal matter…

From dissolved compounds to suspended matter…

From metals to detergents…

There’s no scarcity of contaminants when contemplating wastewater.

However what will we do with the it after therapy?

It’s discharged into the encompassing rivers and streams…

These similar rivers and streams feed into our water reservoirs and thru the identical cycle of water therapy once more after someday.

If that’s the case, wouldn’t it make some sense to reclaim this similar water by treating it?

Wouldn’t it make extra sense to rechannel this recovered water for industrial amd home use?

What ought to occur with a view to make such an formidable transfer work?

HARMFUL MICROORGANISMS

Being probably the most feared water pollution, effectively eradicating microorganisms from our water is central if we’re contemplating reuse.

Although chlorination appears to work for ingesting water therapy, wastewater is a complete totally different ballgame.

By that, I imply that a number of disinfection phases have to be thought of for full elimination of dangerous micro organism and viruses.

Extra R and D have to be geared in the direction of testing some strategies on this regard…

UV Disinfection
Silver Nanoparticles
Modified Activated Carbon…
Potassium permanganate and so forth…

Disinfection of wastewater is essential.

However so is decontamination from dangerous substances suspended and dissolved in it.

DISSOLVED & SUSPENDED MATTER

A technique of lowering suspended matter from wastewater is thru the wastewater therapy course of itself.

Relying on the effectivity of the method, effluent from wastewater therapy vegetation may be additional purified from suspended and dissolved matter.

Although microorganisms could be dangerous, some could be helpful in degrading some suspended matter additional.

That is one technique employed in wastewater therapy.

Nonetheless extra methods may very well be utilized to utterly degrade different dissolved and suspended substances.

The usage of steel oxides reminiscent of titania, zinc oxide and magnesium oxide is gaining prominence because of their sturdy catalytic exercise towards some dissolved pollution.

The usage of adsorption can be vital on this regard.

Adsorption is the flexibility of a fabric to build up pollution on its floor thereby performing as a ‘filter’.

Helpful adsorbents in water therapy embody zeolites, silica, activated carbon, rice husk ash and so forth.

In different phrases, there are a complete vary of the way potential innovators might use to get well water from wastewater effluent.

CONCLUSION

To ensure clear ingesting water for all (a constitutional proper), innovators have to roll up their sleeves and get to work.

Already the present water sources are overstretched.

So why not take into account non-conventional sources reminiscent of wastewater effluent?

Different nations (like Namibia) have finished it efficiently.

So can we.
