Explanation:
Detailed explanation-1: -A sieve has holes in it that are big enough for some of the things in the mixture to go through. Bigger objects get trapped in the sieve. You can use a sieve to separate a mixture of marbles and water, but you cannot use one to separate sand and water.
Detailed explanation-2: -Filtration: the process for separation of mud from muddy water is filtration. If solid particles are in liquids, they pass through filter paper.
Detailed explanation-3: -Take a filter paper and make a cone of it. Fit this filter paper in a funnel. Keep a beaker below funnel. Pour mixture of soil and water in funnel. Water will pass through fliter paper and collect in the beaker. Soil will remain on the filter paper in the funnel.
