What types of filters run with electricity ?
In RO purifier, electric pump increase water pressure to force across the RO membrane.
In Ultraviolate purifier to lighting the ultraviolate tube electricity required.
RO, UV can’t run without eletricity.

What types of filters can run without electricity ?
Ultrafilteration(UF) It uses a hallow fiber tube
for filtration.
Activated carbon It uses coal, wood, coconut
shell etc.
Ultrafiltration and Activated Carbon run without electricity.

Why gravity basedno-electricity Water Purifier?
Frequent power cuts in your area.
No continues tap water facility.

Technologies used in gravity based no-electricity Water Purifiers
Ultra filtration(UF)
Activated Carbon

How UF works?
Ultra filtration uses hollow fibers of membrane.
Water passes though the hollow fibers .
Suspended solids and solutes of high molecular weight are retained in fibers.

For what type of waterUF purifier suitable
If dissolved salts is limited in treated water public supply water or well, pond, river and rain harvested waters.

UF disadvantages Not remove dissolved
solids in water.
Effective when preceded by carbon adsorption or when combined with other purification methods.
To maintain a high pressure water flow, regular cleaning is required.

How Activated Carbon works?
Activated Carbon is a natural material derived from coal, wood, coconut shell etc.
Dissolved chemicals in water flowing over the carbon surface “stick” to the carbon in a thin film while the water passes on.

For what type of waterActivated Carbon purifier
suitable
Activated carbon not effective on hard ground water.
Activated carbon best suitable for lake, municipal supply water on least cost.
Activated Carbon filterdisadvantages
Not effective on bacteria, virus.
Not successful at removing dissolved contaminants or metals such as minerals/salts

Conclusiongravity fed water
filtration systems are a simple, but very efficient way to provide your family with safe water.
If your budget is low , gravity based no-electricity water purifier is best suitable.
