A simple solution is the Lifestraw, “The Lifestraw is an inexpensive way to deliver potable water to those in need, and it is considered an icon of humanitarian product design – it was included in Cooper Hewitt’s Design for the Other 90% exhibition, which featured products, architecture, and technology that has a positive impact on under-privileged demographics around the world” (Inhabitat ). People can drink from the Lifestraw from any

63 million people in the world- that’s 1 in 10, do not have access to clean water. This forces them to drink water contaminated with impurities like runoff from fertilizers, industrial pollution from nearby manufacturing plants, iron, lead, aluminum, barium, arsenic, and coliform bacteria. The alternative to this is using filters either built, bought, or donated by organizations such as The American Red Cross; but do these filters really work? The objective of this lab, is to discover whether or not certain filters actually purify water to a high enough quality to be able to safely drink.

Instead of being defeated by this, Clorox saw an opportunity to reposition its Brita brand as a “green” product to replace plastic bottled water, which was causing landfills to become clogged. By using Brita water filtration systems instead of bottled water, consumers would prevent millions of empty bottles each year from being dumped into landfills and Clorox saw this as an opportunity to revive the fast dying Brita brand. By conducting a successful marketing campaign, which promoted the green attributes of its water filtration system, educating customer about bottle waste and its affects on the environment, and encouraging them to switch to the Brita brand, sales of Brita water filtration system began to rise. To get consumers excited about the product and involved in the bottle “saving” process, the company created a website called FilterForGood which allowed consumers to pledge that they would reduce waste by switching to Brita. It also totaled the amount of bottles saved so that consumers could see how they were saving the environment and encourage them keep on using the Brita water filtration system.

The groundwater source is from GoldCentury gold mine, whereby excess groundwater is pumped out of mine at a maximum volumetric flow rate of 477L/s. It contains contaminants such as volatile organic compounds (VOCs), heavy metal impurities, sulphates, bicarbonates, microorganisms, dissolved minerals and objectionable gases, but focuses on the removal of dissolved inorganic contaminants such as calcium and iron. The most prevalent dissolved minerals which are Calcium and Magnesium, also known as hardness, can be removed by precipitation, requiring softening steps. The purification system designed is based more on efficiency over cost effectiveness. The purpose of treating the groundwater in this assignment, is to purify it to drinking standards to hydrate mineworkers underground during heated, intense mine-work operations, and for operating certain equipment and tools.

areas. The Urban areas are in Dhaka, Khulna and Chittagong Metropolitan Cities and the rural areas are Jessore, Gazipur, Netrokona, Kishoregonj, Naryangonj, Narshindi and Sunamgonj district.

During DSK’s decade of operation it has piloted a number of microcredit delivery methods to evolve an appropriate system to serve the poorest effectively.( Jinia,2016)
