Fog Dehumidification Research Paper

Abstract

The most conventional way to attain water is from underground source and most of the world turns to ground water sources to meet its drinking water and agricultural needs. But like all sources that too comes at a cost and at some places it is not easily available as in other places.

Fog dehumidification technique has been studied as an alternative to the ground water. It’s a creative and innovative technique designed to catch and condense the fog into water droplets which runs down the mesh into a storage container.

Introduction

Overview

Currently most of the world turns to groundwater sources to meet its drinking water and agricultural needs. However, pumping water from aquifers requires a lot of energy and leads both to ground water

The mesh arrangement will be used to collect water which is not contaminated. The water will be clean and pure. There will be no impurities in the water as it is directly condensed from the fog which is enriched in water content. The collect water will be according to the health standards and will be drinkable.

Standard Fog Collector (SFC)

The standard fog collector is a small fog collector of 1m x 1m area on the inside of the frame. The frame is made of a rigid material or aluminum in order to provide rigidity to the structure. The diameter or width of the frame is normally 1cm. this type of structure is used where the water to be collected is in small quantity or for the experimental use.

Large Fog Collector (LFC)

The large fog collectors are very large in size as compared to the SFC. The typical arrangement contains 12m x 2m area on the inside mesh. The frame used for supporting such a large mesh is typically wooden. Wood logs are used to tie the mesh net with in order to provide rigidity in high winds and other weather conditions.

Past

The mesh is used to catch and condense the fog. The fog is rich with water content. The mesh catches the fog and condenses it into water droplets which run down the mesh into the piping which leads the water to the water container for storage. These water droplets are clean of any kind of impurities.

Climate Conditions

Fog is like a cloud which is physically in-contact with the earth’s surface. There are many processes of forming fog. In one method, low stratus clouds can form on a cold body of water, for example, the subtropical SE Pacific Ocean, and the resulting cloud base height above the surface and the thickness of the cloud may be a few tens or hundreds of meters. If such a cloud is moved by the regional winds toward the coastal mountains, the travelled fog may occur in the region having mountains. Another way to produce fog is adiabatic cooling of humid air masses when they move to the uphill. Oceans are mainly responsible as the source of humidity so that the combination of an ocean with a near-coast mountainous region is a desireable setting for collecting water from such orographic fog. If rain is a very limited source of fresh water, and groundwater is not according to the health standards and expensive source, then the fog collection projects are very necessary and they make sense to be installed. These conditions lead to a considerable number of fog collection
