generate the pressure‚ because it does not diffuse. ACTIVITY 5: Filtration What were the results of your initial membrane analysis? Solute Residue for all solutes (Na/Cl‚ Urea‚ Glucose‚ Powdered charcoal) were present. Does the membrane MWCO affect filtration rate? Yes‚ the larger the MWCO the faster the filtration Does the amount of pressure applied affect the filtration rate? Yes‚ the greater the pressure‚ the faster the filtration Did all

Activity 1: Simple diffusion Introduction: Simple diffusion is the net movement of substances from a region of high concentration to a region of low concentration so its overall net movement is along the concentration gradient‚ simple diffusion does not require energy therefore it is ’passive’‚ substances are diffused across the membrane between the phospholipids. Materials and methods: * 20 mwco dialysis membrane * 50 mwco dialysis membrane * 100 mwco dialysis membrane * 200 mwco

ANATOMY AND PHYSIOLOGY Chronic Kidney Disease Cardiovascular System The cardiovascular system is sometimes called the circulatory system. It consists of the heart‚ which is a muscular pumping device‚ and a closed system of vessels called arteries‚ veins‚ and capillaries. As the name implies‚ blood contained in the circulatory system is pumped by the heart around a closed circuit of vessels as it passes again and again through the various "circulations" of the body. The Heart * The heart

also had a high refusal for salts as well as high refusal for organic contaminants. With the constant development and improvement of reverse osmosis membranes‚ they were able to take a step towards the commercial market first in 1965 with a water filtration pilot program utilizing the method in Coalinga‚ California under the leadership of Joseph W. McCutchan and pioneer Sidney Loeb. In 1977‚ Cape Coral‚ Florida started to use reverse osmosis on a citywide

are not in a fixed ratio‚ and while some mixtures‚ such as concrete‚ are useful‚ others including salt water‚ are not as useful to us. Filtration‚ distillation‚ paper chromatography‚ and centrifugation are just a few methods used for separating mixtures. There are many methods of separating mixtures. A more commonly known and used method is filtration. Filtration separates mixtures using filter paper‚

heterogeneous mixture from substances commonly found at the beach. Sand and salt water will be added to the beaker to be separated. The sand will then be separated through the means of filtration. Then the salt will be separated from the water through evaporation. Theory: If the heterogeneous mixture is separated through filtration then the salt water and sand should be separated completely.A heterogeneous mixture is a mixture that is not evenly distributed throughout. If the homogenous mixture is separated

activities contaminated groundwater in 1815. The three experiments were being conducted to determine whether oil‚ vinegar and laundry detergents have an effect on groundwater contamination. The experiment was also being conducted to establish whether filtration is an effective method of water treatment. Furthermore‚ the experiment was done to examine the difference in colour and smell between contaminated and treated water. Another objective behind these experiments was to examine which drinking water

Title of experiment 3: Gel Filtration Chromatography of LDH INTRODUCTION Gel filtration chromatography is a type of column chromatography in which separated protein‚ peptides and amino acids on their molecular size. The stationary phase consists of beads containing pores. The mobile phase is the solvent that is found both around the beads and in the pores of the stationary phase matrix. As the sample is passes through the column‚ the molecule that are larger than the pores will not retarded by

Solutions Offered by Rochem in Various Platforms 1. Reverse Osmosis: It is one of the most widely used technologies to treat industrial waste water. It has been commonly used to remove salts and various other impurities so as to improve the parameters such as pH‚ biological oxygen demand‚ chemical oxygen demand. This technology is already on the rise because of its efficacy and cost efficiency. Reverse Osmosis is a phenomenon wherein water is separated from a solution of dissolved solids by the
