The Importance Of Water Treatment

The goal of all water treatment process is to remove existing contaminants in the water, or reduce the concentration of such contaminants so the water becomes fit for its desired end-use.Sea water desalination process is actually done by converting salty sea water into fresh usable water.This is to increase the oxygen content in the water, to reduce the carbon dioxide content in the water, and to remove organic compounds such as methane, hydrogen sulphide and other volatile which is responsible for taste and odour of water.Distilled water and deionised water have been the most common forms of purified water, but water can also be purified by other processes including reverse osmosis, carbon filtration, micro porous filtration.For the wat...

Rate of Activity of the Enzyme Catalase in Hydrogen Peroxide Experiment

This caused the production of oxygen (bubbles) to happen sooner and since both sides of the filter paper disks are reacting in the beginning (as compared to only one side reacting at the beginning until it somewhat rises into the 3% hydrogen peroxide solution) it resulted in a decrease in amount of time taken to rise to them top of 3% hydrogen peroxide solution which increases relative reaction rate of the enzyme catalase.The dried filter paper disks become less sticky and fall off the rubber stopper (when trying to insert them into culture tubes) into the 3% hydrogen peroxide solution before the culture tube was inverted.To fix this problem, heat up the catalase enzyme extract solution to the desired temperature condition and use that c...

Brita Products Company Essay

Positioning choicesAt the beginning Brita company positioned the pitcher as a purification system providing water of unique taste.This functions as an asset to support and boost the sales of Brita’s pitcher (or any other water purification system), as there is high degree of brand awareness.Filters decrease health hazards by low quality tap water (even if not all dangers are eliminated).We believe that Clorox made an important decision for the promotion and advertising campaign under the idea of taste (“great tasting water”, “clear, fresh, wonderful”) because it was also consistent with the attributes of the core product (water indeed tasted better after filtration with a Brita pitcher).The publicity given to health problems due to water...

Introducting Brita to China Global Marketing

This is not just due to a water shortage, but also to extensive water pollution, which has led to increased and above-average mortality rates among those without access to safe drinking water.The government has no real answer to address either the water shortages or the extensive pollution that plagues their water supply, and makes its way into the mouths of 300 million of its citizens.The competition is now fierce in China for water filtration companies, as the drinking water remains poor.There is little to gain in promoting the BRITA filtering water bottle within China’s lower income and rural areas; instead, we will build our promotion around an idea that will provide clean water for many of China’s less fortunate citizens.BRITA Water...
