Tanzanian engineer invents low-cost water filter

It looks good enough to drink but just seconds before, this water was full of dirt and bacteria.
Dr. Askwar Hilonga is a Tanzanian scientist who has created a water filter that he says can remove 99.9 percent of bacteria, micro-organisms and viruses.
The invention uses nanotechnology to filter out contaminants and produce clean water, and with ionized water filters you will have this with no problems.

Many areas are supplied with hard water meaning that your domestic water will contain minerals, iron and other impurities. This can cause water appliances such as washing machines, water heaters and dish washers to become clogged up and as a result, they don’t last as long as they should. Hard water can also affect laundry, work surfaces and bathrooms by creating an excess build up of lime scale. Installing a best water softeners for well water which will result in appliances and clothing lasting much longer. There are numerous brands on the market so it’s extremely important to go online and research the best water softener reviews. You will come across brands such as Calgon, Kenmore, Rainsoft, Waterboss and many more. The choice can be mind boggling so you need to look out for water softener consumer reports, water softening ratings as well as prices and ease of installation. If you find that water in your area is hard, then get a plumbing inspection. You can also check some best water softeners reviews.

One of the most popular top selling make is Calgon. The name is actually short for ‘calcium gone’ because it contains substances which react with minerals such as calcium, to eradicate them from your water supply. This particular brand, along with others such as Fleck, has undergone independent agency testing to prove that they work effectively to soften water. Always read the packaging on your water conditioning system to see whether this testing has been carried out by the likes of the Water Qualification Association or the National Sanitation Foundation.

Water tank prices can vary so it’s sensible to shop around at premiumlegionellaservices.co.uk/water-tank-installation-repair/ in order to get the best deal. Once you have managed to narrow down your search you will need to consider running costs, the size of your tank, efficiency ratings and whether an extended warranty is included in the price.

It will probably be the improvement to your kitchen countertops that you will notice first. You won’t need to use so much cleaning product on them to leave them smear free. This is all down to the water being softer. Your bathroom will seem shiner because there won’t be the usual lime scale lurking about. Your utility bills will become cheaper too because having a water softener allows your boiler to heat your water up much faster. They also got to rent a chiller from Power Mechanical to ensure that water is at the temperature you like. Lime scale deposits will be prevented from forming and this will allow all of your water appliances including your shower to run more efficiently.

Softer water is kinder to skin and hair so you may find that you don’t have to spend so much on hair conditioners or moisturizers. Your clothing will come out of the machine completely clean and fresh when laundering with soft water. Hard water naturally causes detergent and dirt to become trapped in the fibres of the clothing and this is what commonly causes fading and dullness. Special detergents have been created to deal with this problem but by adding a water conditioner to your home, you need only buy one generic detergent to clean all of your clothes. This is a great bonues as you will no longer need to purchase laundry softening detergents so this will save you money. It’s also common for hard water to create stains in clothing which are hard to shift, so softening your water will alleviate this particular problem.

If you do live in a hard water area you probably spend a fortune on bottled water every week. Any section online about the best water softener reviews will explain that softened water tastes so much better than hard water. Both the taste and the smell of your domestic water will improve dramatically. By not buying bottled water you will be doing your bit for the environment as well.

The filter can be tailored to absorb anything from copper and fluoride to bacteria and viruses. Gravity pulls the water down through a series of buckets connected by tubes. The buckets contain sand with a layer of ‘good’ bacteria on the top, which eat the microbes that contain diseases like Typhoid.
The magnetic quality of the sand also kills other bacteria as the water filters through it.
The final bucket uses nanomaterials to filter out any remaining microbes. In short, an invisible biological ‘net’ which stops bacteria from passing through, but allows the water to reach the final bucket bacteria free.
Dr. Hilonga was one of only four students in his year to graduate from primary school. He went on to university and won a scholarship to study a PhD in nanotechnology in South Korea.
When he returned home, he started looking for ways to use his expertise to help people to start with the reverse osmosis for your home.
“In Tanzania, 70 percent of households, of nine million households, are not using any kind of a filter. That is how big the market is. That is in Tanzania alone, nine million households. Now imagine in Kenya, Uganda, Ethiopia, sub-Saharan Africa, India and elsewhere. So the market is very big,” Dr. Hilonga explained.
One filter is capable of supplying many litres of clean water a day.
The Blue Sky primary school in Arusha uses it to quench the thirst of more than 70 children.
“We analysed the water around, and we have a river like 50 metres far from here, and we saw that it is not healthy, that water. Then we took water from the government supply, but we also saw that it was not going to be healthy and we want the best things for our kids, so we decided to buy the filter,” said Blue Sky primary school headteacher, Elena Ramos.
Dr. Hilonga has received a grant from the U.S. government to help him make his filter available commercially. One filter costs about 140 U.S. dollars.
He hopes the filter will one day be used to help communities and villages across Africa access clean water.
