Bayer Saves 1m Gallons Through Water Reuse

Bayer HealthCare has saved more than a million gallons of water since January with a wastewater treatment system at its animal health division headquarters in Shawnee, Kan.

CDI Industrial & Mechanical Contractors, Inc. of Kansas City, Kan., began installation on the proprietary wastewater system in early 2010. Since the system came online, Bayer says it has been able to reuse about 20,000 gallons of water a day.

The treatment system filters water through carbon adsorption tanks, removing any organic contaminants.  The treated wastewater is then transferred directly into the Shawnee facility’s cooling towers where it is used for office building temperature control and process temperature control in the production facility.

Previously, wastewater from the manufacturing process was only treated by adjusting its pH level.  After tests were conducted to confirm the wastewater was within the proper pH range, it was sent down drains into the municipal sewer system for further treatment at the local municipal treatment plant.

The process modification reduces Bayer’s need for using city water for make-up to the cooling towers, and also reduces the volume of wastewater sent to the local municipal treatment plant, Bayer says.

The Mechanical Contractors Association of Kansas City recognized CDI and its installation of the wastewater system with an Outstanding Mechanical Installation award at its semi-annual awards banquet in July.

Last September the Carbon Disclosure Project named Bayer as a leader in both carbon footprint and disclosure.

The company is aiming for Gold-level LEED for commercial interiors (LEED-CI) certification for a $17 million renovation project at its U.S. headquarters in Pittsburgh. Bayer opened a “climate neutral” office building in India last January.

  1. Bayer’s wastewater treatment system and reuse strategy is a great step in the right direction. Not only has it allowed Bayer to reduce its costs by decreasing the amount of municipal water it needs to buy from the municipality, but it also has allowed it to decrease the amount of wasted water that would have been processed again (increasing overall cost) and returned back into the sewer system. I would be interested to see a municipal incentive put into place that rewards companies (and eventually individuals) for decreasing the amount of water dumped into a sewer that then has to be re-processed. Could they offer a similar water credit to that which is being worked on with the smart-grid technology? Additionally, I think the ability to scale down and make affordable this type of water treatment and reuse technology, will be beneficial to the growing sustainable residential building space by being able to save homeowners money in the long run.

  2. Is Bayer doing any chemical/pharmacuetical treatment that can be shared with the healthcare community? We’re working on waste water treatment for hospitals but working to understand how these emerging contaminants can best be captured. Having Pharma behaind this huge effort would be tremendous.
