Reverse Osmosis For Wastewater Recycling Reusing treated wastewater for beneficial purposes‚ such as agricultural and landscape irrigation‚ industrial processes‚ toilet flushing‚ or groundwater basin replenishment‚ is growing in response to environmental and economic concerns. One of the key factors involved in recycling wastewater treatment plant (WWTP) effluent for another use is the need to reduce total dissolved solids (TDS). This is often done by using a reverse osmosis (RO) system‚ which

benzophenone was quenched with sulfuric acid‚ and an extraction was performed in order to separate the organic phase containing the triphenylmethanol from the aqueous phase. The triphenlmethanol was then isolated and purified by crystallization and vacuum filtration. Reaction Scheme: Mechanism: The nucleophilic phenyl magnesium bromide attacks the electrophilic carbonyl of benzophenone to form a magnesium alkoxide. This is followed by hydrolysis by an acid to produce the alcohol‚ triphenylmethanol.

Kharishma Patel BIO 3422-E Urine Analysis Lab Objective The objective of this experiment shall be to examine the effects of different types of fluids on the renal system including rate of urine production‚ pH‚ and specific gravity. Hypothesis The group drinking water will have the highest rate of urine production. The group that drinks water only when thirsty will have the lowest rate of urine production. The specific gravity of urine for all treatment groups will be around 1.000. The pH for

sulphuric acid will be added to the refluxed solution‚ which will cause the salicylic acid to precipitate. This will then be filtered through suction filtration. Once the product has dried‚ purification must be done by recrystallization; dissolving the product in a minimum amount of hot solvent (water)‚ and then filtering once again through suction filtration. Finally‚ to complete the main purpose of the experiment‚ which is to compare the prepared product with a standard (salicylic acid from benzene)

The Effect of Enzymes on Apple Juice Production Biology Period 6 Background Info The purpose of this experiment was to determine which enzyme or the combination of the two enzymes makes the most apple juice from applesauce. We did his by‚ mixing 10 drops of an enzyme (cellulose/pectinase/both) into a few tablespoons of applesauce. We then left the rest to nature‚ and watched the liquid funnel out for 10 minutes. Lastly‚ we recorded our data. The cell wall is a complicated

for human life. Tenants‚ where factory workers and their families lived‚ were filled with problems. They had no filtration‚ making the air dirty and unsafe and were extremely cramped. This lead to deadly disease spreading quickly. One such disease was tuberculosis‚ which was spread by breathing in infected air by someone who had already contracted the disease. Without a good filtration system in the tenants‚ tuberculosis spread very easily. It was thought to have caused one-third of deaths over a

All surface water and some groundwaters require treatment prior to consumption to ensure that they do not represent a health risk to the user. Health risks to consumers from poor quality water can be due to microbiological‚ chemical‚ physical or radioactive contamination. However‚ microbiological contamination is generally the most important to human health as this leads to infectious diseases which affect all populations groups‚ many of which may cause epidemics and can be fatal. Chemical contamination
