On-Site Hypochlorite Generation
On-site generation refers to the process of producing water treatment chemicals on-site at a water treatment facility, rather than transporting them from off-site locations.
On-site generation can offer several advantages in terms of water quality. For example, it can provide greater control over the quality and consistency of the treatment chemicals, reduce the risk of chemical spills during transportation, and minimize the need for storing large quantities of chemicals on-site.
Additionally, on-site generation can be more cost-effective and environmentally sustainable, as it reduces the energy and carbon footprint associated with transportation.
On-site generation can help improve water quality by ensuring that treatment chemicals are produced and applied consistently and reliably, reducing the risk of contamination and ensuring that water is safe for human consumption.
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.
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.
Removes safety concerns around gas chlorination and the maintenance of associated safety equipment such as emergency gas scrubbers.
Addresses safety and economic concerns around delivery of a hazardous material like 12.5% commercial bleach.
Our next generation cell configuration is inherently superior to previous generation of horizontal electrolytic cells for safety and production continuity.
