The greatest benefits of the Hydraid® BioSand filter (pictured right) for the work we do in very rural and remote communities include:

Biosand Filter : 19 Steps (with Pictures) - Instructables

A biosand filter is a simple type of water purification system that uses sand gravel gravity and some simple engineering to purify water contaminated with biologics and some chemicals. Its structure is generally made of concrete or plastic and is filled with layers of gravel and sand that encourage the growth of good microbes that are naturally present in water just like in the ground in nature.

Sand as a filter media - Biosand filter

In slow sand filtration the vertical height of the sand bed that the water has to pass through is important in terms of filtration efficiency. The reasons for this are the existence of biological activity in a sand filter which is known to occur at depths of up to 0.5m within a sand bed and the available surface area for mechanical filtration and chemical reactions.

Biosand Water Filter - Water Filtration for a Better Life

The biosand water filter has six distinct sections. The first section is the inlet reservoir where contaminated water is poured into the filter. The second section is a resting water level formed by raising the standpipe connected to the spigot.

Water purification using sand | SpringerLink

Slow sand filters are used to purify drinking water. Each filter consists of a large tank containing a bed of sand through which water passes at typical rates of 0.1–0.3 m h−1. Water is cleaned by physico–chemical and biological processes occurring at the air–water interface within the bulk water over the surface of the sand and within the bed of sand. The processes found in sand ...

How Biosand Water Filtration Systems Work

It has an inset plastic pipe and is filled with layers of sand and gravel. Dirty water is poured into the top of the biosand filter where a diffuser plate evenly distributes the water over the sand bed layer. The water travels down through the sand bed passes through multiple layers of gravel and collects in the plastic pipe at the bottom of the filter. The clean water then exits through the plastic piping for a family to collect in clean containers.
