The researchers found that the use of biochar could lead to a significant improvement in bacterial removal from wastewater when compared with unamended sand biofilters, and their nuanced results provide important evidence for future exploration of ...What Centrifugation Is and Why It's Used,  · If the bucket spins fast enough, the water is pulled inward and doesn't spill. If the bucket is filled with a mixture of sand and water, spinning it produces centrifugation.According to the sedimentation principle, both the water and sand in the bucket will be drawn to the outer edge of the bucket, but the dense sand particles will settle to the bottom, while the lighter water molecules will ....
