Austrian design company, EOOS and water research institute, Eawag strives to improve sanitation in areas of extreme poverty with the use of mobile toilet which has a water filtration system independent.

Toilet as ‘The Blue Diversion Toilet’ was developed with the aim to improve the living conditions of 2.5 billion people who have difficulties of access to sanitation, and a major cause of serious diseases worldwide.

“We have designed a toilet that can be used anywhere. From the slums of Kampala, Uganda until at weekend house belonging to a millionaire,” said Designer The Blue Diversion Toilet, Harald Grundl.

Toilet Blue Diversion formed from a blue plastic with a high reach 190 centimeters. The toilet consists of a shallow bowl at the bottom and the water reservoir container and circulation system at the top of the back. In addition, it also provides facilities toilet sink and shower for cleaning.

Container inside the toilet bowl will separate the dirt with two different tank to 20 liters of urine and 15 liters of faeces. Having collected for three to four days, the dirt can be used as fertilizer.

Fluid from the sink and shower were siphoned and recirculated through the filtration system allows the provision of clean water for washing hands. Provision is made without the need to connect to the main water supply.

Grundl states, a system such as that contained in the toilet Blue Diversion is very important to use in developing countries and extreme situations, such as refugee camps with water supplies difficult to obtain.

“For the first time, clean water will be available in regions with water shortages,” said Grundl.

Eawag has now developed a version of the same filter for use in tap water in major cities with the name of ultrafiltration membranes. Membrane filters usually require regular cleaning to remove dirt that clog and therefore requires a lot of energy.

Eawag version of the filter membrane avoids this by using microorganisms suspended in a liquid. By using gravity to push the liquid through the filter, the microorganisms help clean the dirt through a natural biological process. This filtering system is ultimately capable of producing water that theoretically clean enough to drink.

The filtering system requires only 11.5 watts of energy that has been provided through solar panels. It is keeping the water moving around the system with a variety of pumps and power of flushing mechanism.

“Compared to conventional water recovery technology. This system has a low energy requirement. This can be achieved because the water used to wash into the low contamination source separation thanks to technology,” said Grundl.

The toilet is made of polyethylene plastic types with steel rods as a supporter. This facilitates the design of the toilet when locally produced and transported. The designers estimate that these toilets will be managed and leased by small businesses.

“Implementation of this system depends on how well our business model. There is no solution that relies on permanent subsidy will function in the long term,”

The toilet has two field tests, namely in Uganda in 2013 and Kenya in 2014. The current design is the fourth version and the second prototype working.

Many components have been redesigned since the first reshuffle toilet. This is done to make the toilet more suited to mass production. But a team of designers still hope to reverse some of the parts and reduce the cost of making that this toilet into commercially viable products marketed according to their target.

Water taps Tech H20, Save Water 30 Percent

Everyone needs water to bathe and cleanse the body. Clean water is the most important thing of course, but over time, the amount of water usage also affect a person’s life experience. The more water used, the fresh sensation after the bath becomes increasingly felt.

But many people do not realize, the use of excessive impact on the water supply in the future. Delta Faucet Company General Manager Asia Pacific, David Naber, seek appropriate solutions so that customers do not use too much water. “We utilize H20 Technology to create the latest products, Brizo. This technology reduces the amount of water that flows without the user realizing it.

This technology, continued David, enables users to experience the fun in the bath. Users will feel the water running pretty much even though not as much as expected. The trick, David modify the size of the droplets of water flowing from a shower head. The amount of water droplets vary in each product. However, David claimed the consumption of water savings can reach 30 percent.

“Users do not want to experience the bath is reduced with a little stream of water. This technology helps provide comfort while reducing the use of water,” explains David.

In addition, the product also pocketed certificate Brizo Environmental Protection Agency (EPA) WaterSense 2013. The program aims to protect water supplies in the United States in the future. WaterSense certification is given on the main criteria of the EPA that the water flow of 1.5 gallons per minute for faucets and 2.0 gallons per minute for a shower.

WaterSense labeled products alone could reduce the use of 20 percent water. One product WaterSense labeled Delta Faucet is Sotria. This product carries the tail design of a triangular aircraft on the muzzle. This faucet is specifically designed to be installed in a bathroom with a choice of four variants namely Polished Chrome, Brilliance Luxe Nickel, Polished Nickel, and Matte Black.

Sotria was launched in the US in November 2014. The price is priced around 400 US dollars, or Rp 5.2 million per unit. Although quite expensive, he believes its products can compete in the segment. Besides WaterSense, Sotria include H2O technology Technology that is a system controller dynamics of flow, pressure, and water temperature. This technology also makes it easy to enable users simply tap through the touch in some parts of his body.
