When this process is utilized, there is an increased risk in the release of unwanted by-products can cause severe health risk. The use of chemical disinfection methods, results in the creation of disinfection by-products through the interaction of the disinfectants with natural organic matter (NOM) (Bougeard, Goslan, Jefferson, Bruce, and Parsons, 2010). Due to the minute amounts of the disinfectant by-products, a reliable…

    can be used to advantage. Ethylene glycol is added to water in car radiators to increase the boiling point in hot conditions and to act as antifreeze in cold conditions. The boiling point of water will increase 0.512°C for each 76 g of ethylene glycol (antifreeze) added to 1000 g of water and the freezing point will decrease 1.86°C for each 76 g of ethylene glycol added to 1000 g of water. This is also why salt is sprayed on roads in cold areas—reducing the chance of ice forming by lowering the…

  • Chlorine: Safe Drinking Water

    penetrates the surface. When the acid enters the germ it pierces the barrier of the germ slime coating and destroys the micro-organisms containing the diseases. Sometimes instead of using elemental chlorine other products containing chlorine such as sodium hypochlorite (bleaches) or chloramines are used. Sodium Hypochlorite is bleach that can be produced in two ways: o When chlorine gas is dissolved in sodium hydroxide, which produces sodium hypochlorite water and salt. Cl2 + 2NaOH + → NaOCl…

  • Persuasive Essay On Water Testing

    treated a certain amount of testing should be done to ensure that the treatment equipment will handle the problem and that it is sized correctly. Those treating city water, have the advantage that this water is tested to meet safety requirements and in some cases it may also be treated.

  • Chlorine Argument Essay

    and then the products that are formed are chlorine gas, hydrogen gas and sodium hydroxide. The reaction at the anode is the oxidation of the chloride, with the spectator ions being sodium. 2Cl^-→〖Cl〗_2+〖2e〗^- Then the sodium chloride solution that didn’t oxidise flows through the diaphragm into the cathode side where water has dissociated. H_2 O↔H^++〖HO〗^-. The H+ then goes and reduces at the cathode to form hydrogen gas2H^++2e^-→H_2. Then at the end sodium hydroxide solution exits the cell…

    shown reduced nanoleakage and good bond strengths. Prati et al have introduced the concept of Reverse Hybrid layer. In conventional hybrid layer , the mineral phase of dentin is removed by acid etching and replaced by resin infiltration around the exposed collagen fibres. In reverse hybrid layer, after acid etching and exposure of collagen fibres, application of NaOCl is done to remove exposed collagen fibres and also solubilise the fibres down into the underlying mineralised matrix to create…
