Suspension filtration works by passing a mixture of solid particles and liquid through a filter medium. The solid particles are too large to pass through the filter, so they are retained on the surface or within the pores of the filter. The liquid, which is now free of the solid particles, passes through the filter and is collected on the other side. This process separates the solid particles from the liquid, allowing for the purification or concentration of the liquid. **
