SEWAGE TREATMENT Sewage is a mixture of domestic and industrial wastes. It is more than 99% water‚ but the remainder contains some ions‚ suspended solids and harmful bacteria that must be removed before the water is released into the sea. The treatment of wastewater is divided into three phases: pretreatment‚ primary treatment and secondary treatment. Pretreatment Large solids (i.e. those with a diameter of more than 2cm) and grit (heavy solids) are removed by screening. These are disposed of in

Diffusion And Osmosis Abstract In this Diffusion and Osmosis lab a total of three experiments were performed. For experiment 5.1 we investigate diffusion through a selectively permeable membrane and the many factors that influence the rates of diffusion. In experiment 5.2 we investigate both animal and plant cells in different molar solutions and the different osmotic behaviors within the cells. In experiment 5.3 we test the osmolarity of plant cells through the usage of potato tuber cells

Introduction The aim of this experiment is to see the effect of different Pectinase concentrations have on the production on apple juice. Pectinase is an enzyme‚ which breaks down pectin‚ a polysaccharide found in plant cell walls. This enzyme is mainly commercially used to speed up the process of fruit juice production as the cell walls of plants are broken down more quickly. Therefore by changing the Pectinase concentrations‚ the results may show the effects it may have on how much apple juice
