In a nutshell, a sodium hypochlorite generator uses electrolysis to convert a saltwater solution into sodium hypochlorite, hydrogen, and sodium hydroxide. It’s a cost-effective and efficient way to produce a powerful disinfectant on-site.
So, why should you keep reading? Because understanding the nitty-gritty details can help you make an informed decision, and let’s be honest, who doesn’t love a good science lesson?
Operating Principle
The core of an On-Site Sodium Hypochlorite Generator is its electrolyzer cell, where a brine solution (or sea water) flows through. When direct current is passed through the cell, electrolysis occurs. This results in the production of chlorine gas at the anode and sodium hydroxide and hydrogen gas at the cathode. The chlorine gas then reacts with sodium hydroxide to form sodium hypochlorite, a potent disinfectant.
Chemical Equation
For those who love the science, the chemical equation is
NaCL+H2O = NaCLO+H2↑
(Sodium hypochlorite)
NaCLO + H2O = HCLO + NaOH
(Decomposition into hypochlorous acid )
HCLO → HCL + [O]
(The new ecological oxygen precipitation )

Operational Requirements
Salt: 4.5 kg to produce 1 kg equivalent of chlorine
Electricity: 4-kilowatt hours to produce 1 kg equivalent of chlorine
Final Solution: Approximately 0.8% (8 grams/liter) sodium hypochlorite
PH Range
The generated solution has a pH value between 8 and 8.5
Advantages of On-Site Sodium Hypochlorite Generator
Cost-Effectiveness
The system only requires water, common salt, and electricity, making the total operating cost significantly lower than conventional chlorination methods.
Environmental Safety
The hypo solution produced has a concentration of less than 1%, making it non-hazardous and reducing carbon emissions.
Operational Flexibility
On-site generation allows operators to produce only what is needed, when it is needed, offering greater control over the disinfection process.
Advantages of On-Site Sodium Hypochlorite Generation in Mitigating Corrosion
Commercially produced hypochlorite solutions can be corrosive due to their high pH and chlorine concentration. On-site generators produce a less aggressive solution, minimizing the risk of corrosion in the piping system.
Addressing Scale Formation with On-Site Sodium Hypochlorite Generation
Commercial hypochlorite solutions can cause calcium carbonate scaling due to their high pH. On-site generators do not have this issue, as the produced solution has a balanced pH.
Gas Emission Concerns With Commercial-Grade Hypochlorite Solutions
Commercial hypochlorite solutions decompose over time, generating oxygen gas. On-site generators produce fresh sodium hypochlorite, minimizing gas production and associated risks.
On-site generators eliminate the need for storing or handling hazardous materials, making them a safer option for operators.
Chlorate Formation
The Concern
Chlorate ion formation is a significant area of concern in the electrochlorination process. Sodium hypochlorite degrades over time to form chlorate ion (ClO3-) and oxygen (O2). The degradation is dependent on the strength of the solution, temperature, and the presence of metal catalysts.
Decomposition Mechanisms
High pH Formation: 3NaOCl = 2NaOCl + NaClO3
Temperature Increase: Leads to chlorine evaporation loss
Implications
A high concentration of Chlorate is not advisable in drinking water as it poses health risks. Therefore, understanding the conditions that lead to chlorate formation is crucial for safe and effective disinfection.

FAQ
1, What is the working mechanism of sodium hypochlorite?
Sodium hypochlorite works by denaturing proteins in microbial cells. It disrupts their structure, hampering their function and ultimately leading to cell death. In a broader context, sodium hypochlorite acts as an oxidizing agent, effectively breaking down and removing stains, soils, and microbial load.
2, How does sodium hypochlorite turn into chlorine?
Sodium hypochlorite can yield chlorine gas under acidic conditions or high temperature. The acid or heat can split sodium hypochlorite molecules, releasing chlorine gas.
3, What is the bleaching mechanism of sodium hypochlorite?
The primary reactions that cause bleaching damage with sodium hypochlorite involve the incorporation of chlorine into double bonds and the conversion of hydroxyl groups into either aldehydes or ketones through oxidation.
4, What is the difference between bleach and sodium hypochlorite?
Sodium hypochlorite, or NaOCl, is a compound formed when chlorine interacts with a solution of sodium hydroxide. These substances are the primary by-products in most chlor-alkali processes. Often known as bleach, sodium hypochlorite serves multiple purposes and is highly effective as a disinfectant and antimicrobial agent.
5, What is the mechanism of bleaching process?
(a) Mechanisms of Bleaching
Degrading agents like oxygen, ozone, and chlorine-based compounds, including hypochlorite, are mainly employed for the bleaching of chemical pulps. Their action involves the elimination of phenolic structures and the breaking of carbon-carbon double bonds.
6, What is the process of bleaching chlorine?
(1) Chlorine lightens through an oxidative mechanism and requires the presence of moisture for its bleaching effect. When it comes into contact with water, it forms hydrochloric and hypochlorous acids.
(2) Hypochlorous acid is not stable and readily breaks apart to release elemental oxygen.
(3) This elemental oxygen is a more potent oxidizing entity.
7, What is the method of production of bleaching powder?
The formation of bleaching powder involves the passage of anhydrous chlorine gas over dry slaked lime. The primary chemical reaction can be represented as: 2Ca(OH)2 + 2Cl2 → Ca(OCl)2 + CaCl2 + 2H2O.
8, What are the three types of bleaching?
When it comes to laundry bleaching, you essentially have two primary options: chlorine-based bleach and oxygen-based bleach. Additionally, there are natural substances that possess bleaching capabilities and can serve as bleaching agents.
9, What are the 7 stages of bleach?
The progression of lightening dark hair occurs in seven distinct phases:
Stage 1: Black/Brown
Stage 2: Dark Brown
Stage 3: Light Brown
Stage 4: Dark Blonde
Stage 5: Medium Blonde
Stage 6: Light Blonde
Stage 7: Icy Blonde/White: At this final stage, almost no pigment should be left.
10, What is the difference between chlorine and bleaching?
The fundamental distinction between chlorine and bleach lies in the fact that chlorine is a naturally occurring element, while bleach is a compound made up of multiple elements. Chlorine bleach specifically refers to bleach containing sodium hypochlorite as its active ingredient.
