On-Site Hypochlorite Generation

How Hypochlorite Generation Compares to Traditional Methods

On-site sodium hypochlorite generation refers to the process of generating sodium hypochlorite (NaClO) directly at the location where it will be used, rather than transporting and storing pre-made hypochlorite solutions.

The process involves the electrolysis of saltwater (NaCl) to produce sodium hypochlorite solution, which can be used as a disinfectant or oxidizing agent in water treatment applications.

This method of hypochlorite generation has several advantages over traditional methods of chemical production and transportation, including cost savings, increased safety, and reduced environmental impact.

On-site generation eliminates the need for transportation and storage of hazardous chemicals, which reduces the risk of accidents and spills. It also allows for precise control of the concentration and dosage of hypochlorite, resulting in more efficient and effective treatment.

As concerns mount and regulations change regarding the safety and security of chlorine gas used for water disinfection, many utilities are choosing sodium hypochlorite, or bleach as it is commonly known, as a safer alternative. 

On-Site Hypochlorite Generation (OSHG} is the safe, sound, clean and green disinfection option.

Design Advances Create Surge in OSHG Adoption

On-site hypochlorite generation (OSHG) systems for disinfection have seen an increased adoption rate in the last decade as water and wastewater utilities continue to grapple with the onerous complexity of risk management plans (RMPs) in the case of gas chlorine disinfection and the operational or cost challenges of using bulk 12.5% sodium hypochlorite for disinfection. 

Since the early 1990's, OSHG systems in North America have used electricity to convert simple table salt (sodium chloride) into 0.8% (8,000 ppm) bleach or sodium hypochlorite.  

Design Advances

The latest generation of OSHG systems have been designed to emphasize safety, reliability and maintainability.  Design advances have all contributed to the latest surge in OSHG adoption. Examples of such advances are:

• Vertical electrolytic cells that vent by-product hydrogen immediately away from the system
• Modular cell configurations which allow for operational contingencies
• Efficient power management
• Open architecture

In most regions, acceptable paybacks are achieved by replacing bulk hypochlorite delivery with enhanced operator and ratepayer safety.

Why More Utilities Choose OSHG

Some of the largest water utilities in the country have turned to OSHG systems to better manage their hypochlorite disinfection issues.  Here's why.

Safety  

Removes safety concerns around gas chlorination and the maintenance of associated safety equipment such as emergency gas scrubbers.

Reduces Costs

Addresses safety and economic concerns around delivery of a hazardous material like 12.5% commercial bleach.

Better Design

Our next generation cell configuration is inherently superior to previous generation of horizontal electrolytic cells for safety and production continuity. 

Easy to Maintain and Operate

Engineered for ease of maintenance and simplicity of operation, Microclor® OSHG has clear cells, replaceable cells and a simplified transformer/rectifier.

Microclor® OSHG, cleanwater1's innovative OSHG product, is ideal for utilities that need 20 PPD to 2,400 PPD of chlorine equivalent produced.  Microclor® OSHG is the safer, economical disinfectant alternative to gas chlorine and concentrated sodium hypochlorite.
