    interior and exterior of the cell. The second type is active processes which use energy known as ATP to power the transport. There are two main types of passive processes called diffusion and filtration. This can be split into different types such as simple diffisuion‚ facilitated diffusion‚ osmosis and filtration. The objective of these experiments is to provide information on the passage of solutes and water through semi permeable membranes and relate them back to the study of actual living membranes

    activated carbon‚ an adsorbent used in water filtration influence the specific surface area and the porosity. In this study‚ coconut shell was used as the raw material and activation reagents such as Hydrochloric acid‚ Zinc Chloride and Phosphoric Acid were used. A single burn and double burn process was carried out for each method. The activated carbon obtained was compared in terms of absorption capacity‚ bulk density‚ BET specific surface area and pore volume. The best results were yielded for activated

    Water from the dam is screened by removing large contaminants. E.g.: Fallen Trees. Sedimentation: Allowing floc particles to settle out to form a sludge‚ which can be removed from settling tanks periodically. Filtration: Water from the settling tanks is piped to filtration tanks to be filtered. The water at this stage should be clear. Chemical Processes: Aeration: The screened water is then sprayed into the air to increase oxygen levels so that iron salt becomes oxidised and forms

    modifications of filtration and dialysis use a matrix-based fibrous material that provides a mechanism of separation in many homogeneous immunoassays. These materials may be coated with specific antibody-ligand to foster selection of specific materials or species. Certain labels use magnetic particles in conjunction with strong magnets to effect separation. Basic universally used separation mechanisms‚ outside of those incorporated in immunoassay‚ are centrifugation‚ filtration‚ and dialysis
