Air Products - OXY-DEP® VSA Wastewater Management System

The innovative OXY-DEP VSA process is a new on-site system that is changing the way municipal and industrial wastewater managers look at oxygen treatment. Quick and easy to install, the system can be deployed rapidly to cope with sudden increases in demand or provide a reassuring back-up to cope with regular fluctuation.

THE OXY-DEP VSA WATER TREATMENT PROCESS

Many water treatment plants experience regular peaks in demand as populations vary or production increases. This puts a strain on the people and equipment responsible for delivering clean water. Coping with this changing demand was the challenge for Air Products' water treatment specialists. They came up with an innovative new way of approaching oxygen treatment - the OXY-DEP VSA process.

By generating oxygen on site the OXY-DEP VSA process can increase the capacity of your treatment plant. It means oxygen is available on demand and is mixed straight into your wastewater basin helping improve performance at peak times.

CLEAN WATER PRODUCTION LEGISLATIVE CHANGES

The changing face of legislation governing waste means added pressure on those responsible for producing clean water. European environmental guidelines and country legislation require that we are aware of, and comply with, a range of standards.

The European Water Framework Directive (WFD) will have important implications over the course of the next few years, as will the Urban Waste Water Directive on the collection and treatment of some biodegradable wastewater. All this means that there has never been a more important time to reassess the efficiency of your wastewater plant, and consider new, innovative treatment processes.

WASTEWATER FLOW CHANGES

Changes in the concentration or volume of waste can occur at any time, both in municipal or industrial wastewater plants. Caused by seasonal variation in population or an increase in production, it can lead to systems being stretched even further.

Extreme temperatures also play a role, reducing the efficiency of the aeration process and affecting the biology of the plant. For a system operating close to capacity and which is less efficient than when it was new, this extra strain can prove too much.

OXY-DEP VSA: A NEW APPROACH TO WASTEWATER TREATMENT

These new demands call for a change in the way we look at the problem. The OXY-DEP VSA process is just that - a totally new approach to wastewater treatment. Using our extensive knowledge of on-site oxygen generation, we have developed the first treatment process where oxygen can be generated on demand using only an electric power supply.

This means that oxygen, which is generally a more effective process enhancer than air, can now be added to the treatment to boost capacity whenever it is needed. Quick to install and cost-effective to run, the OXY-DEP VSA process provides the peace of mind that comes from knowing you can cope with fluctuating demand no matter what happens.

OXY-DEP VSA WASTEWATER TREATMENT PROCESS BENEFITS

The OXY-DEP process is an ideal solution for municipal and industrial wastewater systems that need to increase capacity:

• Quick, easy installation
• Immediate treatment capacity
• Ideal for meeting fluctuations in flow
• Improved plant performance
• Cost-effective, fixed-price rental
• Peace of mind

TRADITIONAL OR OXY-DEP VSA WASTEWATER TREATMENT PROCESSES?

• When the capacity of a plant needs to be increased to deal with more waste, there have been only two options to date:
• Physically increase the size of the reservoir basin
• Add trucked-in liquid oxygen, which is generally more efficient than just adding additional aeration at low dissolution rate efficiency

These are both expensive options.

The new OXY-DEP VSA process offers a cost-effective way of generating oxygen on-site. This is a departure from oxygen-based remedies that have existed for the last 20 years. Easy to install and deploy, it provides the peace of mind you get from knowing you can cope with any eventuality.
