Almost all what you need to know about Bio-sand filters

A biosand filter (BSF) is a point-of-use water treatment system adapted from traditional slow sand filters. Biosand filters remove pathogens and suspended solids from water using biological and physical processes that take place in a sand column covered with a biofilm. (Wikipedia)

How a bio-sand filter works ?

Video by : Samaritan’s Purse

Pathogens and suspended solids are removed by biological and physical processes that take place in the biolayer and the sand layer. These processes include:

  • Mechanical trapping: Suspended solids and pathogens are trapped in the spaces between the sand grains.[1]
  • Predation: Pathogens are consumed by microorganisms in the biolayer.[1]
  • Adsorption: Pathogens are absorbed into each other and to suspended solids in the water and sand grains.[1]
  • Natural death: Pathogens finish their life cycles or die because there is not enough food or oxygen.[1] (Wikipedia)

Now, it’s time for the juicy part : How to make a professional Bio-sand filter ?

There are 100s of DIY videos on Youtube on how to make a Bio-sand filter, but most of them are not enough to get the whole scientific and technical idea behind the BSF.
Don’t get me wrong, you don’t have to be an engineer or a technician to understand it .
Just read this AMAZING PDF file I found online by CAWST, explaining the very basics of the BSF… Check out the content :

These 11 Cities May Completely Run Out Of Water Sooner Than You Think

For decades scientists have been saying that the United States’ lakes, rivers and aquifers are going to have a hard time quenching the thirst of a growing population in a warming world. A recent report from NOAA’s Cooperative Institute for Research in Environmental Sciences does not alleviate those fears. It showed that nearly one in 10 watersheds in the U.S. is “stressed,” with demand for water exceeding natural supply — a trend that, researchers say, appears likely to become the new normal. “By midcentury, we expect to see less reliable surface water supplies in several regions of the United States,” said Kristen Averyt, associate director for science at CIRES and one of the authors of the study. “This is likely to create growing challenges for agriculture, electrical suppliers and municipalities, as there may be more demand for water and less to go around.”

A one scoop shower !

Once we started a simple campaign in the  street to talk to people about the importance of water and our huge waste .

And we distributed some decent flyers having some info about water waste , one of them was written on it  ” A 10 minutes shower uses about 90 Liters of water ” …

Then a man asked us ” Ok , its great , what do you want me to do ? , do you want us to stop taking shower ? “
We answered ” Of course not , we just want you to use less amount of water ” 
He wasn’t convinced , and he asked again about a solution , it’s like we were accusing him of wasting water during shower and we don’t have a solution to the problem ….

Well , i saw an amazing ad on the AsianDevelopmentBank account on Youtube ….

Sower man

An almost one minute ad showing a man brushing his teeth , washing his hair and body with only one scoop of water , almost 2 Liters

Its not impossible , and its not hard to get used to it , as there is one constant in the equation which is that you have to take a shower every now and then , but there is two variables ( Time & water ) ….

Simply : Reduce shower time , and don’t open the shower head you have all the way up …

That is our reply to the man who asked us about the solution , yes , we want you to do like the man in the ad as much as you can  , water is scarce ..

Finally :
Take action in spreading out the  message to the world , that is our reverie , our dream , A WATER WISE PLANET !

One burger sandwich requires more than 2,500 Liters of water !

Good evening everybody ,
Today we wanted to introduce you to the term ” Virtual water ” .
Virtual water is the water used in the industry of our daily life products , whether it was food , clothes or electric appliances .First of all , we are not telling you to stop eating burger , we justwant you to appreciate what you have for granted .
We want you to know the real value of WATER
As we all should know , water is included in EVERYTHING we use in our life , even the oxygen you breath , and yet we never know how much are we dependent on it !We have collected some good resources that will get you out of your mind while reading it !

BurgerFor example , lets start with the ” Beef ” :
Don’t look at it as it is just a small sandwich of beef , it takes on average three years before the animal is slaughtered t produce about 200 kilos of boneless beef.

During these three years the cow consumes about 1300 kg of grains to eat !
There is Also roughage , and roughage requires water … etc

It is a process of constant renewal …
We don’t want you to be bored from our long presentation , please check this amazing websites that will tell you more and more about ” The hidden water we use ” through an interactive way that you will never forget .
