The design target was to reduce free chlorine levels of 1.0 ppm to less than 0.01 ppm, with 500 ppm of IPA present in the water. The outlet limit of 0.01ppm of free chlorine was chosen based on a "1,000 ppm-hours" rule-of-thumb. This "rule" set a guideline for a thin film RO membranes exposure limit to free chlorine.

Chlorine is available in one of three forms: sodium hypochlorite, calcium hypochlorite and liquid chlorine. 1.Sodium hypochlorite, commonly called "liquid bleach", is commercially available in strengths approximately 15% by weight. It can be added to the receiving stream by gravity, by the use of a chemical metering pump, or by physically ...
The electrochemical process for the production of sodium hypochlorite involves a series of oxidation-reduction reactions. Initially, the poles generated by electrodes result in the formation of ...
Sodium hypochlorite (NaClO) is a strong oxidizer, a disinfectant, extremely corrosive to metals, strongly alkaline and hypertonic (Tiwari et al., 2018); moreover, sodium hypochlorite is a bleaching agent (Flores et al., 2009). In turn, population growth and its corresponding increases in water consumption coupled with limited freshwater ...
The production process of sodium hypochlorite consists of a first block where the chlorine, caustic soda and hydrogen are produced in an electrolytic cell from brine and a …
Typically, these systems are rated to consume anywhere between 1 – 9 short tons of chlorine per hour. Contact us if your project requires a higher or lower flow rate. Standard systems have adjustable production rates and can produce as much as 220,000 gallons 818 m 3 of 200 grams per liter available chlorine of sodium hypochlorite in 24-hours.

installed in Boonton, N.J., replacing the use of sodium hypochlorite bleach. These developments paved the way for the future extension of water disinfection techniques utilizing liquid chlorine. Hypochlorite water chlorination gradually decreased in popularity, but it received renewed interest in 1928 with the commercial availability of high ...
The process is based on the partial electrolysis of NaCl present in seawater as it flows through an unseparated electrolytic cell. The resulting solution exiting the cell is a mixture of seawater, sodium hypochlorite (hypo), hydrogen gas and Hypochlorous acid. ... Chlorine generated at the anode immediately goes through chemical reactions to ...
• The selected dechlorination process must be able to neutralize the chlorine to levels below 0.01 mg/l. • Testing needs to be done at the point of discharge, the point you lose control of the water flow. • Spread dechlorination chemical in the path of the discharge water to insure that the initial water will make contact with the chemical.
The application of the chlor-alkali process is to produce 3 main chemicals: chlorine, caustic soda and caustic potash.
