Filtration Removal of contaminants from fluids (liquids or gases) using porous media Micron 1 micron (um) =10－6 m ＝10－3 mm= 3.9×10 -5 inch Three filtering mechanisms 1.Direct interception Basic filtration mechanism in liquid The essence is a sieving effect, mechanical interception of particles For example: a simple screen can intercept the size, particles larger than their pore size. When the particles are larger than the flow channel aperture, they are removed by the structure. The dirt holding capacity can be improved by the curved structure Screen does not have this effect Particles smaller than the pore size can also be intercepted by bridging Irregularly shaped particles / directionality Multiple particles hit the same filter at the same time 1). Irregular shape bridge 2). Multiple small particles 2.Inertial impact Auxiliary interception method for particles smaller than the pore size of the filter material Fluid-carrying particles ha...

Fundamental of filtration 1. filter Filtration is the operation of the solid and liquid separation by allowing the liquid in the suspension to pass through the pores of the porous medium under the action of an external force, and the solid particles in the suspension are trapped on the medium. Description 1). wherein the porous medium is referred to as a filter medium; the treated suspension is referred to as a filter slurry; the solid particles retained by the filter medium in the filter slurry are referred to as filter cakes or filter cakes; the liquid passing through the filter medium is referred to as a filtrate. 2). driving force of the liquid through the filter medium can have gravity, pressure (or pressure difference) and centrifugal force; 3). The purpose of the filtration operation may be to obtain a clean liquid product, or to obtain a solid product. 4). Washing effect: recover the residual filtrate in the filter cake or remove the soluble salt in the filter cake....

HOW TO MEASURE THE PRESSURE DROP Whenever you're pumping fluids through a pipe, you need to pay attention to your pressure drops. A pressure drop happens whenever fluid is met with resistance. That means it will happen over a stretch of pipe, through a filter or a strainer, through a valve, or any other type of pipe fixture. Pumps counter-act the pressure drops in your pipe system. In fact, you should be adding up all these pressure drops and resistances to select a pump that is capable of efficiently overcoming them. In other words, the pressure drop is a critical measurement that cannot be ignored. However, we often switch out pipe fixtures with little regard to the pressure drop and its effect on our pumps and processes. We even operate our control valves without monitoring the pressure drop we’re creating. Or we ignore our filters and let them clog because we do not actively monitor the pressure drop. PRESSURE IS DYNAMIC As we fluctuate pressure drops and resist...

                                  Pressure drop Pressure drop is defined as the difference in total pressure between two points of a fluid carrying network. Pressure drop occurs when frictional forces, caused by the resistance to flow, act on a fluid as it flows through the tube. The main determinants of resistance to fluid flow are fluid velocity through the pipe and fluid viscosity. Pressure drop increases proportional to the frictional shear forces within the piping network. A piping network containing a high relative roughness rating as well as many pipe fittings and joints, tube convergence, divergence, turns, surface roughness and other physical properties will affect the pressure drop. High flow velocities and / or high fluid viscosities result in a larger pressure drop across a section of pipe or a valve or elbow. Low velocity will result in lower or no pressure drop. The fluid may also be bi...
