Darcy’s Law expresses flux of water without particles through a nonwoven membrane as follows: J=∆p/(μ.R_m ) (4) where, J is the permeation flux (m3/m2s), ∆p is the transnonwoven pressure (Pa), μ is the viscosity (Pa.s), and Rm is the clean nonwoven membrane resistance or intrinsic resistance (1/m). Since fouling is going to take place in the separation process, the permeation flux will always be lower than the flux given by Eq. 4. Cake resistance -formed by cake layer- and fouling resistance…

Fracking is the process of drilling deep into the earth’s crust and injecting water, sand and chemicals under immense pressure in order to obtain natural gas. With this process there are benefits and also disadvantages. There are many risks to groundwater from surface spills that are associated with shale energy development, they can be managed or mitigated by following certain precautions and steps. Groundwater is present throughout the atmosphere. There is surface water, atmospheric water and…
