water would be another challenge. 8. Is the water treated prior to its discharge? If so‚ with what? Sodium hypochlorite (bleach solution) is used to kill remaning organisms in the water grom the final settling tanks. The second stage is water DE chlorination‚ this is where chemical (sodium bisulfite) is used to neutralize the bleach prior to the clean water discharge. 9. Where is the treatment water discharged? Potomac River 10. Who monitors the discharge of treated effluent to ensure that it meets

of potential causes for smelly water‚ and the following are some of the most common. Chlorine Almost everyone is familiar with the bleach aroma of chlorine in the water. It may appear stronger at times‚ and this is typically due to excessive chlorination in public water sources. Chlorine is used by water treatment facilities for water disinfection and treatment. A Benjamin Franklin plumber in Arlington can provide the solution for chlorinated water with water filtration‚ eliminating not only the

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

chlorine is passed into boiling alcohol‚ both chlorination of the methyl group and oxidation of the primary alcohol group to an aldehyde occur‚ giving trichloro-acetaldehyde or chloral: When chloral is treated with caustic alkali‚ fission of the C-C linkage occurs‚ giving chloroform and a formate. Acetaldehyde and also many ketones‚ such as acetone‚ containing the CH3CO- group behave similarly when treated with calcium or sodium hypochlorite‚ chlorination of the CH3CO- group being immediately followed

Water Technology Hardness of Water: Natural waters containing large quantities of dissolved salts of Calcium (Ca) & Magnesium (Mg) is called hard water. It is a characteristic of preventing lather formation of water with soap. Ca2+ & Mg2+ ions react with soaps which are salts of fatty acids (stearic or palmitic acid) to give insoluble scums or precipitates of calcium or magnesium stearate or palmitate. 2C17H35COO- + Ca2+ → (C17H35COO)2 Ca (scum) 2C17H35COO- + Mg2+ → (C17H35COO)2
