170508 Water Recycling and Animal Farm

On the 8th of May, 2017, we went to the water treatment plant in Birsfelden called Ara Birs. Basel (Switzerland) has five(5) bigger plants and 22 smaller ones. The first two that was built in a very long time was built in the year 1963 and 1977 and was renovated and re-modernized in 2007. The company's name Ara Birs was derived from a river called Aare which passes through Bern, Solothun and Aargau and its mouth enters the Rhein river. They recycle rain water, waste water from habitat and water from roadside. The waste water of about 1000 habitat goes to Ara Birs for treatment.During raining season, they are able to collect about 4000 cubic meter of water everyday for treatment.
The recycling goes through 4 processing, first it goes through mechanical cleaning, where bigger particles are separated from the water then from there it goes through another mechanical cleaning where smaller particles are separated from the water and to the chemical processing where more oxygen is added to the water and in the next process the water is allowed to settle and some of the sewage sludge that settled is collected into the digester chamber to produce methane gas to produce about 40% of electricity they use. They have solar panels all round that produces about 25% to 30% of electricity and in all they produce about 65 to 70% themselves. We were also favored by one of their bosses who decided to buy us three tickets to watch F.C. Basel soccer match on Sunday. We came home from there.







After supper we went to Auntie Regula's farm to see what they do there. It was really nice. The whole family are hard workers. The dad, the mum and the children. We saw the fat cows they had, the fat dog and cats, the fat and sporty horses, the rabbits and how the milk was taken from this fat cows. The machines and the processes used there were beautiful. We had the chance to taste some cold fresh milk and to ride on the horse back. It was really fun. All the cows had there names and even the dog was called Deeva, it was lovely. On the farm, nothing goes waste, the water from the home of the farmer and his children which is on the farm goes into a big tank and its used to water the the plants to be sold and the grasses to feed the animals during summer. The droppings of the cows are used as manure to fertilize the land for planting. The milk of the cows collected are sold and they are able to collect about 1400 litre s of milk per day.









After there I went to play soccer with DEF.C.
