Traditional Method for Home Water Purification Of the various methods available for water purification‚ it was found that about 20 million people of the target market used the traditional boiling of water as their purification method. Boiling was considered inexpensive and helped in removing bacteria. Mechanical methods for home water filtration In the mechanical methods of home

The active fraction obtained was pooled together‚ concentrated by lyophilization and used as purified fibrinolytic enzyme for subsequent studies. The summary of purification steps involved for fibrinolytic protease is presented in the Table: 1.

Great Religions and Philosophies. : Greek Philosophy. In the 6th century B.C‚ there began a dualism in Greek Philosophy. The development of Greek Philosophy became a compromise between Greek monistic and oriental influences‚ in other words‚ a combination of intellectualism and mysticism. Thus began the pre-Socratic philosophy. The interests of pre- Socratic philosophers were centered on the world that surrounds man‚ the Cosmos. This was during the time of great internal and external disturbances

the two questions that were to be answered in experiment 2. The equation of this reaction is as follows (and is the same as that found in experiment 2):  During this experiment‚ we used recrystallization methods in order to help in the purification of the unknown solid‚ as well as drying and vacuum filtration. We then ground the unknown and combined it with different chemicals (such as acetanilide or phenacetin) and used the melting point ranges to determine the identity. We used the Mel-Temp

PRODUCTION OF VALUE ADDED PRODUCTS FROM USED TYRES THROUGH PYROLYSIS ABSTRACT Pyrolysis has the potential of transforming used tyres into useful recyclable products. This paper demonstrates the conversion of scrap tyres into its primary products which are Pyro Oil and Carbon Black and a secondary value added compound‚ Activated Carbon. Further‚ the objectives of the work also include optimization of parameters such as temperature and feed size to study the efficiency of pyrolysis at different

3: Variables Independent variable: The methods of removing lead nitrate (Pb(NO3)2) from water. There are various ways to remove lead dissolved into water. Many of them are expensive and/or very industrial. Due to my circumstances‚ I chose five that were somewhat doable. The five methods are coagulation‚ carbon filtering‚ reverse osmosis‚ ground coffee filtering‚ and distillation. Coagulation was done by using a flocculant (aluminum sulfate) that clump small‚ destabilized particles together so that

different rituals. In the Christianity faith we observed individuals prayer to their higher being. Muslims pray five times daily facing east to the city of Mecca. In Hindu religion we observed water purifications to rid the body and or mind of physical and spatial realms. Hindu believes that the purification allows one to connect on a more spiritual level with their god. With our finds from Earth‚ we have determined that this planet is indeed a religious
