WASTEWATERTREATMENT

WHAT?New Hospital Herlev is con-structing a new wastewater treatment plant that will ensure that hospital waste-water is handled in accord-ance to the Environmental Protection Act’s regulations. The project is designed as a private-public innovation partnership.

WHY?Hospital wastewater is characterised by a complex mixture of hazardous phar-maceuticals, harmful patho-gens and antibiotic resistant bacteria. These cannot be removed by conventional means of wastewater treat-ment.

WHO?The private project partners consist of Grundfos Bio-Booster as project holder, DHI for testing and docu-mentation, Ultraaqua as a specialist in carbon, ozone and UV light and Neutralox for odour control. Herlev Hospital will build and own the wastewater treatment plant.

EXPECTED RESULTS:• Constructionoffull-scale

• Evaluationofrobustness,cost of operation and treatment performance in order to help define best available technique

• Demonstrationthatairemissions can be treated for pathogens and odours

• Demonstrationthattheby-products can be dis-posed of in an environ-mentally sound matter

• Developingacontrolmethod to detect when granular activated carbon filters are saturated in order to optimize replace-ment intervals.
