The objective of the project was to develop a novel package plant using available process technologies that would be competitive in the domestic waste water treatment market. A market analysis identified the business opportunity for Balmoral Tanks to develop a package plant with higher treatment capability than its current product. A customer survey and a review of Regulatory standards provided valuable input into the design considerations for the package plant. A review of available process technologies and materials of construction resulted in the selection of a Moving Bed Biolm Reactor (MBBR) process and High Density Polyethylene material as the optimum design basis for the package plant. A detailed design exercise scoped out and specified all the components of the MBBR package plant. A four month duration programme for testing the prototype at Cranfield University facilities was devised which satisfactorily simulated typical domestic wastewater treatment operating conditions. Test rig problems associated with very low ambient temperatures were experienced in the early stages of testing and were identified and resolved. The prototype package plant unit subsequently operated satisfactorily and the performance was demonstrated to meet all the wastewater constituent removal design specifications. The MBBR process performance was shown to be consistent with published findings of other researchers. Novel fabrication methods developed by Balmoral Tanks resulted in the cost of the new MBBR package plant being only 3% higher than that of Balmoral Tanks current lower specification product. The new MBBR package plant is shown to be a potentially very marketable domestic wastewater treatment product.
