Abstract

The project site is a farm located in Sydingösby. The Gunnarsson family is living here. Carina and Stefan have two children. Stefan works at the farm while Carina works at SLU. This site has already a system for waste treatment, but it is not satisfying and not sustainable. Actually it does not permit a good reduction of BOD, nitrogen or phosphorus coming from the waste, and does not offer good recycling of the nutrients. Moreover the family has planned to build a guest apartment, and need to install toilets in the honey room. Thus maybe some of the existing parts of the current one-site system need to be re-dimensioned. And a new system has to be installed to fulfill the aims of BOD, N and P removal. In the first part we are going to describe the site, the current one-site system and the problems which occur. Then we are going to analyze in three other parts three possibilities to improve the waste treatment: the urine diversion, the composting, and the sand filter. We will after that conclude with the system seems to be, according to us, the best choice.
