The process examined is a typical sodium process. This process consists mainly in passing chlorine into a slurry of slaked lime and sodium hydroxide, generating Calcium Hypochlorite and sodium chloride. After separation steps, Calcium Hypochlorite (about 70 wt%) and an aqueous solution of sodium chloride are obtained as products.
1. 100kg of calcium hypochlorite 65% into 1 MT of water. The solution will be bleaching liquid at a density of 6.5% effective chlorine. 2.1% disinfection liquid can be formulated by adding 1.7 g of calcium hypo 65% into 1 MT of water. Advantages: 1) High effective chlorine content; 2) Good stability.
In chemistry, hypochlorite is an ion with the chemical formula ClO −. It combines with a number of cations to form hypochlorites, which may also be regarded as the salts of hypochlorous acid. Common examples include sodium hypochlorite ( bleach) and calcium hypochlorite (a component of bleaching powder, swimming pool "chlorine").

On-Site Generation of Sodium Hypochlorite ( <1% available Chlorine ) 3.0 BASIC OPERATING THEORY Generating Sodium Hypochlorite onsite is a simple and straightforward process that uses
What you see above, is a video of how sodium hypochlorite can be made at home. ("UC235", 2010)Structure Parts We know that the compound of sodium hypochlorite is made up of 3 elements which are; sodium, oxygen and chlorine.
Batch and Continuous Bleach Production Systems designed to manufacture sodium hypochlorite with greater efficiency and higher quality than previously obtainable. The process, which uses liquid or vapor chlorine and caustic, is versatile and has the design capability of making any concentration of sodium hypochlorite solution from 2 trade percent up to 20 trade percent.
This diagram illustrates the entire Chloralkali process. The chloralkali process uses salt and electricity to make chlorine, caustic soda, and hydrogen on-site for the production of sodium hypochlorite, ferric chloride, calcium hypochlorite, hydrochloric acid, and other chlorine derivatives, or to produce feed stocks for a variety of other chemicals.

preparing sodium hypochlorite by chlorinating a solution of caustic soda. Varying concentrations of this solution have found a multitude of applications so that the general public is now well acquainted with the material. This handbook will discuss sodium hypochlorite solutions. Sodium hypochlorite solutions have attained widespread use in ...
Calcium hypochlorite exhibits both acido-basic and oxydo-reduction properties: it is a strong base (as it accepts proton) and a strong oxidizing species (as it accepts electron). A calcium hypochlorite solution is basic as the hypochlorite anion can easily accept a proton from a water molecule leaving an hydroxyl anion in solution.
The RMIC values are based on a maximum dosage of 20 mg of calcium hypochlorite/liter of water and are to be com pared to impurity concentrations obtained by using sample procedures described in this monograph. If the actual dosage is other than 20 mg/liter, the user is cautioned to consult Table 2 for appropriate RMIC values.
Hypochlorite was the original form of chloride used for the disinfection of drinking water. Known as chloride of lime, calcium hypochlorite (Ca(OCl) 2) is a solid which can be used as a powder, granules or in tablet form and is still widely used today at smaller WTPs. The more familiar liquid sodium hypochlorite (NaOCl), which is commonly known ...
Sanitation. Calcium hypochlorite is commonly used to sanitize public swimming pools and disinfect drinking water.Generally the commercial substances are sold with a purity of 65% to 73% with other chemicals present, such as calcium chloride and calcium carbonate, resulting from the manufacturing process.
A cyclic process for producing calcium hypochlorite from sodium hydroxide and calcium hydroxide by chlorination with chlorine gas, which comprises the steps of: (a) adding sodium hydroxide as a solid or as a thickly concentrated aqueous solution into an aqueous solution saturated with calcium hypochlorite and sodium chloride;
Calcium hypochlorite is generally sold as 68% calcium hypochlorite combined with calcium chloride and other salts. It is used as a sanitizer in outdoor swimming pools. The calcium content hardens the water and tends to clog up filters; hence, some products containing calcium hypochlorite also contain anti-scaling agents.
Calcium Hypochlorite: Formula, Properties, Risks and Uses ... Its structure is shown in figure 1. Figure 1: structure of calcium hypochlorite . The production process of calcium hypochlorite basically consists of a reaction of hydrated lime (calcium hydroxide) with gaseous chlorine by the chlorination of a slurry of lime and caustic soda With ...

Calcium hypochlorite is added in granular or tablet form to swimming pools to kill germs that can make swimmers sick. Calcium hypochlorite destroys germs that are capable of causing numerous health problems for pool users–diarrhea, swimmer's ear (a nasty earache) and various respiratory, skin and wound infections.
