Gas Chlorination Technology

Gas Chlorination Technology

One of the most popular chlorine applications is the decontamination of drinkable water. Gas chlorination leaves a residual, which the US Environmental Protection Agency needs in the water distribution system to prevent pollution in the pipelines, in addition to being a powerful but cost-effective disinfectant. In addition to disinfecting treated wastewater and reclaimed water, gas chlorine is used.

Gas chlorine is used in a variety of sectors for a variety of purposes, including cooling water and intakes, aluminium or gold fluxing, pulp and paper, food and beverage, rubber glove manufacture, flour bleaching, and more.

Chlorine gas has been used for more than a century. The vacuum-­operated solution feed technology ensures optimum safety and allows for versatile designs with various feed locations for varied control techniques. If the chemistry does not produce toxic byproducts, it is usually the least expensive method of chlorination for disinfection or biocide control.

FINDING THE RIGHT DISINFECTION TECHNOLOGY

The application should be carefully evaluated and questions should be asked in order to determine the optimal disinfection technology.

• What exactly are you attempting to achieve?
• What microorganisms are the ones you’re looking for?
• What is the approach for maintaining control?
• Is there a problem with disinfection byproducts?
• What is the capital expenditure and operational expense budget?
• Who will be using the system, and how difficult will it be to operate?
• What safety concerns must be taken into account?

OPTIMIZING INSTALLED ASSETS

To begin, it’s critical to work with renowned, dependable equipment vendors. Make sure you have excellent after-sales service from your local agents or the manufacturer for spare parts and technical assistance.

A site safety assessment should also be completed. Make sure the facility’s Hazard and Operatability Study (HAZOP), Risk Management Program, and Training Program are all up to date. Consider using scrubbers or container shut-off systems.

ALTERNATIVE TECHNOLOGIES

Chlorine gas feed systems are well suited to many chlorination technology applications, and the cost is usually an advantage. We haven’t noticed a reduction in the market for chlorine gas feed systems in favour of other technologies on a global scale. Thousands of gas chlorination systems are in operation and providing reliable service. Around the world, large gas systems are still the gold standard for disinfecting drinkable water.

Some people are considering replacing gas chlorine with other disinfection technologies due to safety concerns. However, current US requirements necessitate stringent risk management and process safety management processes. Chlorine gas system operators are well-trained, and strict safety protocols are in place to avoid any difficulties. The use of chlorine gas has been made much safer thanks to emergency gas scrubbers and container shut-off devices.

Other disinfection technologies should be investigated when chlorinated byproducts are a problem. Chlorine dioxide, chloramination, UV radiation, ozonation, advanced oxidation processes (AOP), and peracetic acid are examples of these processes (PAA).
