Water Distiller – Working Principle, Parts, Types, Uses

What is a water distiller?

A water distiller is a device that is used to purify water by removing impurities and contaminants. It works by heating water to its boiling point, causing it to evaporate and leave behind any solid contaminants. The resulting steam is then cooled and condensed back into liquid form, producing purified water. Water distillers are commonly used to produce purified water for drinking, cooking, and other applications where clean water is important. They can be particularly useful for people who live in areas with poor-quality tap water or for those who want to ensure that their drinking water is free of contaminants.

The water distiller transforms the water into steam to remove arsenic, fluoride, viruses, lead, and other impurities.

There are both huge automatic systems and compact countertop models of the water distiller. It can be your reliable ally in gaining access to clean and fresh water for cooking, drinking, and other household applications. It might be a worthwhile investment for a more convenient and healthier way of life at home.

It has various uses in health care facilities, particularly in laboratory units, for cleaning and sterilising.

The distiller’s operation is based on the natural phenomenon known as the water cycle. The sun’s energy warms the water in the oceans and turns a portion of it into water vapour. In clouds, this vapour is concentrated. When atmospheric conditions are favourable, water returns to the Earth’s surface as rain after being cooled and condensed.

Principle of Water Distiller – How Does a Water Distiller Work?

1. The water distiller transforms water into steam by boiling it.
2. The steam is then condensed and cooled to transform it back into a liquid.
3. Everything that cannot be converted into steam, such as minerals and microbes, is left behind.

To initiate the distillation process, water is placed into the boiling chamber. The boiling chamber has a heating element that will bring the water to a rolling boil. As the water’s temperature increases, steam is produced. The top of the boiling chamber is vented, and rising steam goes through the vent into a condenser, leaving germs and fluoride behind. The condenser is a stainless steel tube coil where the vapour will be transformed back into a liquid.

A powerful fan at the top of the distiller cools the vapour, resulting in the formation of water droplets. These droplets then travel through an activated carbon postfilter as they move down the condenser tube. This is because some pollutants, such as volatile organic compounds, can exist in a gaseous condition and may have escaped with the steam into the condenser. Through adsorption, the activated carbon removes any remaining pollutants clinging to the water droplets. The water droplets are then expelled from the distiller and collected in a glass container or stainless steel reservoir.

Parts of a Water Distiller

A water distiller is a device that is used to purify water by removing impurities, contaminants, and other unwanted substances from it. There are several key components of a water distiller:

1. Boiler or heating element: This is the component that generates heat to boil the water. It is usually made of stainless steel and is located at the bottom of the distiller.
2. Boiling chamber: This is the container where the water is heated to boiling point. It is usually made of stainless steel and is located above the boiler or heating element. Glass is used to construct smaller water distillers, whereas stainless steel with copper, tin, or titanium coatings is used for larger units. It is intended to hold the water that will be distilled.
3. Condenser: This is the component that cools the steam produced by the boiling water and condenses it back into liquid form. It is usually made of copper or stainless steel and is located above the boiling chamber.
4. Collection chamber or bottle: This is the container where the purified water is collected after it has been condensed by the condenser. It is usually made of glass or plastic and is located above the condenser.
5. Pre-filter: Some water distillers have a pre-filter that is used to remove larger particles and contaminants from the water before it is heated and distilled. The pre-filter is usually located at the inlet of the distiller, where the water is first introduced.
6. Carbon filter: Some water distillers also have a carbon filter that is used to remove chlorine, pesticides, and other chemicals from the water before it is distilled. The carbon filter is usually located after the pre-filter, before the water enters the boiling chamber.
7. Water Level Gauge: It makes it easier to regulate the amount of water in the vapour generator. When the amount of water in the boiling tank’s liquid phase decreases, the mechanism allows the evaporating liquid to be retrieved.
8. Control valve: It is a device that permits mechanical or electromechanical regulation of the water flow towards the vapour generator tank.
9. Immersion resistors: They generate heat when an electrical current passes through them. These are protected from the external environment by a metal plate and a ceramic cover.
10. Refrigerator water outlet: It is a conduit used to condense water vapour (cooling).

Types of Water Distillers

Types of Water Distillers Based configurations

Distillation systems are available in both manual and automatic variants.

1. Manual distiller system

• It can create only 1 gallon of water at a time. 
• After the first gallon of water is produced, the system must be physically refilled in order to produce the succeeding gallon. 
• The capacity of a manual distiller is determined by the volume of water it can produce per hour. In manual distillation systems, 1 gallon-sized glass or plastic jars are typically utilised.

2. Automatic distiller system

A water pipe is connected to automatic water distillers, which produce pure water continually. When the holding tanks reach a predetermined level, production is halted by electronic controls or float valves. The capacity of an automatic system is determined by its daily output capacity. Automatic distillation systems can hold between 3 and 25 litres of water in a stainless steel reservoir.

Based on their usage in various locations, they are classified as follows:

a. Plumbing distillers

• It may be included into the plumbing system. It could be a cost-effective choice for water distillation. 
• It requires maintenance, such as removing sediments from the bottom of the boiling chamber.

b. Household distillers

• One sort of residential distiller is the easy-to-install single-effect distiller, which may be placed on a desk or kitchen counter. 
• The technology permits the addition of the required amount of water to distil, collect, and filter it.

c. Commercial distillers

• With its multiple-effect distillers, the daily output of these distillers ranges from 75 gallons to millions of gallons. 
• With commercial distillers, multiple boiling chambers are included to produce more distilled water.
