Liquid Waste Management - Wastewater Treatment Process
Industrial companies produce both hazardous and non-hazardous wastewater because of their manufacturing and production systems, including wastewater that contains EPA listed and characteristic wastes. The treatment of this wastewater has become a key component to a profitable operation. Companies require a cost-effective effluent treatment solution that can help them manage their entire wastewater stream that meets all federal and local standards, and is environmentally-friendly.
Covanta recycles millions of gallons of
wastewater every year. Our wastewater treatment process efficiently
deals with all types of wastewater and helps to eliminate the risk of
backups and service interruptions that could dramatically affect your
We start by conducting an on-site
waste stream analysis, utilizing our state-of-the-art laboratory network
to make sure we fully understand the issues you are facing with
wastewater management. We will then produce a Waste Characterization
Statement that lists all of the waste constituents and work with our
customers to select an environmental solution that will best suit their
Our Liquid Treatment process involves physical and chemical treatment techniques
to remove contaminants such as oils, dissolved metals and solids. The
water is then sent to municipal treatment plants for additional
biological water treatment, resulting in clean water that is returned to
the water cycle and typically to surface waters.
Our Liquid Direct Injection technology destroys contaminants and materials in a wide range of waste streams.
We inject liquid waste directly into our advanced controlled combustion
systems where the water is instantly vaporized and the remaining
contaminants and materials are destroyed.
Clean oil products are collected and reused or sold.
For organic waste streams, we
partner with organizations who have anaerobic digester facilities that
can turn wastewater into a renewable energy source.
There is an increasing need for
experience and confidence in the treatment and recycling of different
types of wastewaters, from residential and municipal sources to
industrial wastewater. Covanta has the expertise to provide a
value-added service that meets your needs.
American Airlines Wheel and Brake Center Case Study
The wastewater from American Airlines Wheel and Brake Center is processed through our Liquid Direct Injection process which pumps the waste water through atomizing nozzles directly into the combustion chambers where the contaminants are destroyed and the water is vaporized, thus avoiding landfills and eliminating potential landfill leachate impacts.
