The Swanage Water Treatment Plant
Swanage Bay forms part of the Jurassic Coast World Heritage Site which is renowned for its geological significance and natural beauty. Effective sewage treatment is crucial as it prevents harmful pollutants and pathogens from entering the marine environment, helping to maintain the ecological balance and for the protection of public health. Moreover, a high standard of water quality helps preserve the reputation of this area with its high amenity value for all who enjoy this beautiful location whether for bathing, water sports or its wildlife.
The Swanage sewage treatment plant uses Membrane Bioreactor (MBR) process for treating all the waste water from Swanage even at the height of summer when holidaymakers boost the population to 26,000 people.
The presentation will discuss sewage treatment, focusing on membrane technology used for disinfection at the Swanage Water Recycling Centre (WRC). The talk will include a background into the treatment processes at WRC indicating the advantages and disadvantages of this type of technology. The talk will also examine the challenges faced by the water companies in regards to storm overflows in the face of the changing climate, public perceptions and the regulatory framework.
