trapping contaminants while allowing clean water to pass through. It is
commonly used as a pre-treatment step in water treatment plants before the
water undergoes further purification processes like chlorination or reverse
osmosis.
How It Works
Sand filtration typically involves a
multi-layered filter bed, where water flows through different grades of sand.
The top layer, usually consisting of coarse sand, traps larger particles, while
the finer sand below captures smaller contaminants. The water that emerges from
the bottom of the filter bed is significantly cleaner and clearer, ready for
additional treatment if necessary.
Types of Sand Filters
