Pure Drinking Water in Crisis and its Sustainable Solution

Every person needs at least 20-50 liters of safe & clean water a day to drink,cook and bathe.The world is facing a growing water crisis where half of the world's population is expected to be living in water-stressed areas by 2025.Today, over 2.5 billion people lack access to safe,clean drinking water.[1] 

We are proposing Atmospheric Water Generator(AWG) Technology. It uses condensation process to turn humidity into potable water.The atmosphere contains an astounding 37.5 million billion gallons of water,in the vapor phase.[2]

Bangladesh has Relative Humidity(RH) between 35% and 74%,Temperature between 18ºc and 35ºc.Thus,Bangladesh has the optimum condition to produce large volumes of water from air. It's large coastal area is ideal for AWG.[3] 

 A test has shown AWG can produce:[4]

• If 95% RH,40ºC+ Temp: 8,400 Liters water per day 
• if 85% RH,30ºC+ Temp: 5,640 Liters water per day 
• if 60% RH,25ºC+ Temp: 3,288 Liters water per day

Global AWG Market Size:[5]

Bangladesh has a population of 160 million.But access to safe drinking water is still low at 34.6%.Despite progress,19.4 million people are still drinking water with a level of arsenic above national health standards.The presence of manganese,chloride and iron contamination also reduces the quality of drinking water.More than 41% of people drink water from sources with faecal contamination.A third of the drinking water has high counts of E.coli bacteria that confirmed the MICS survey.[6][7] People have been complaining for long against WASA,a water supplier to 20 million people in the capital,for its stinky, filthy water.BARC found water contains ‘coliform bacteria’,BSTI has no comments on the water supplied by Dhaka WASA.[8] It is reported that 86% of WASA’s drinking water comes from ground water.As a result,the ground water level is falling between 1-3 meters every year.[9] 

Factors:[10]

• Ground water is contaminated with Arsenic,dangerous microbes,heavy metals etc.
• Approx. 43,000 people die each year from arsenic-related illnesses.
• Arsenic free tube-wells are not available in all villages.
• SDG Affairs said that Bangladesh has still a long way to access to clean water and sustainable sanitation by 2030.
• Excessive use of groundwater, now the ground water level is falling between 1-3 meters every year.

In summer, most of the major cities suffer from water crisis. Rivers around major cities have become polluted. In the case of ground-water resource, the presence of arsenic in ground-water is affecting the people of rural areas. More than 41% of people drink water from sources with faecal contamination.This rises to 61.7% at the point of consumption.[11]

Bangladesh is going to face severe water crisis within the next couple of decades due to random contamination of surface and ground water, absence of comprehensive water sharing with neighboring countries and mismanagement in preserving rain water. Today, rivers across the country are being filled up or being encroached upon in such a manner that is threatening the very existence of human habitation.Presently 86% of WASA’s drinking water comes from ground water. Besides, excessive use of ground water during the Boro season may have an adverse effect on the country’s drinking water, warned IFPRI.[12]

All of this is preventable through access to clean water. Now, many new technologies have sprung up that bring water to communities. So,we have to address the social constraints through communities‘Knowledge Attitude Practice’[13]towards life and livelihood and shape the all actions as mass-people oriented action through public participation.

Proposed Conceptual Diagram of Atmospheric Water Generation System: 

How does it Works?

Air + Energy = Water

Systematically process is:

Natural Air -> Air Filter -> Condenser -> Water -> Filtered -> Purified -> Safe & Pure Drinking Water

Technical Characteristics:

The amount of Water Production will depend on Environmental Conditions and on the percentage of relative humidity. It is possible to produce from 50L up to 5000/10,000/20,000 liters of water a day by a unit or units and can be powered by any of them like - electricity, diesel generator, solar power, battery storage system or windmill's turbines generated power etc. For facilitating the production we can consider locally available power sources. This AW generator can be made fixed or movable. Power consumption to produce water will depend on what types of power sources will be used, Temperature and RH of that day. It will operate on 50hz or 60hz and either 220 – 240V (single phase) or 380 – 440V (3-phase). Main part of the generator is the compressor. Therefore, the lifespan of the generator will depend primarily on the maintenance of the compressor.

Types:

Residential, Commercial and Industrial

Description of the Generator:

A Generator unit will consist of two parts:

• Water generation part
• Water reservoir with filter and purification part

These two parts will be easily attachable and separable or fixed.

Equipment of the Generator as a Unit:

• Compressor (Refrigerant R410A)
• Copper/Aluminium tube Condenser Coil with aluminium fins
• Fan
• Air Filter (Multi layers)
• Heat Sink (Aluminium)
• Water Tank (Food Grade Plastic/ BPA-free PET)
• Water Pump
• Automatic Water Level measure equipment
• Power Source with a) Alternator b) Voltage Regulator
• Tray
• Water Filter and Mineralization (Activated Carbon and Mineralizer)
• Purifier (RO) etc.
• Display Units (Temperature & Humidity, Voltage-Current-Power, Water Level, Compressor Pressure etc. meter/sensor)
• Control Panel (Touch Screen/Button)
• Alarm System for Malfunctioning
• Frame and Box

Water Delivery Container:

• Water Delivery Jar (Food Grade plastic/Glass Bottle/ BPA-free PET bottles)

Where this Generator Can be Applicable:

The leading applications are in locations where do not have access to any sources of water.

These include:

• Humanitarian applications in traditional areas of water scarcity
• Island and rural communities with limited fresh water supplies
• Temporary humanitarian applications in disaster or war zones
• Growing industrial and commercial applications
• Corporate CSR programs
• Commercial and industrial

Ideal Places of Bangladesh for Setting this Generator:

• Warm coastal areas with high humidity are ideal
• Other places having high humidity in air

Here we are using environment friendly equipment. i.e. R410a refrigerant and rotary compressor. For cost minimization in Bangladesh aspect the solution offers both types of parts i.e, copper and aluminium made. For getting most safe and clean water using RO purifier, Carbon filter, food grade plastic or BPA-free PET bottle or container. Safety purpose using (Temperature & Humidity, Voltage-Current-Power, Water Level, Compressor Pressure) meter or sensors and will have Alarm system for any malfunctioning etc.

Bangladesh is going to face severe water crisis within the next couple of decades due to random contamination of surface and ground water, absence of comprehensive water sharing with neighboring countries and mismanagement in preserving rain water. Today, rivers across the country are being filled up or being encroached upon in such a manner that is threatening the very existence of human habitation. According to a survey conducted by the BWDB, there are 310 rivers in Bangladesh. Most of these are almost dead. 

It is reported that presently 86% of WASA’s drinking water comes from ground water. Besides, excessive use of ground water during the Boro season may have an adverse effect on the country’s drinking water, warned IFPRI. The excessive use of the ground water, the ground water level is falling between 1-3 meters every year.

Every person needs at least 20-50 liters of safe, clean water a day to drink,cook and bathe. The world is facing a growing water crisis where half of the world's population is expected to be living in water-stressed areas by 2025. Today, over 2.5 billion people lack access to safely managed, clean drinking water.

So, we need to choose a solution or technology that is suitable and sustainable for people to access to safe drinking water along with will create economic and social prosperity in Bangladesh. Measuring the Bangladesh’s climate and environmental infrastructure we can easily choose the Atmospheric Water Generator(AWG) technology that extracts humidity from the air creating pure drinking water from the world's most abundant source – the Atmosphere.

In Bangladesh, no such solution is implemented yet. 

In five years, hopefully will be able to cover most of areas of Bangladesh where have crisis of pure drinking water and gradually will ensure that each and every people of Bangladesh will have to access to pure, clean and safe drinking water.

In five years, hopefully will be able to cover most of areas of Bangladesh where have crisis of pure drinking water and gradually will ensure each and every people of Bangladesh will have to access to clean and safe drinking water.

Need to make people aware of drinking pure water and to know them about approx. 43,000 people die each year from arsenic-related illnesses and excessive use of groundwater the ground water level is falling between 1-3 meters every year.

So, need to arrange "Community Based Program" as - Awareness of health and environment, to make people concern about health and illness, How harmful the ground and surface water are for drinking since these water sources are contaminated with Arsenic and harmful bacteria etc . 

Let the communities know about Atmospheric water, Atmospheric water's health benefits, how hygienic, safe and clean the AWG water is, compare to WASA or available bottled water or surface or tube-well water. We can also offer this technological solution to the communities as Community-Based-AWG setup, it might be done through NGOs.

1. Financial and Technical issues are the barriers to reach my goals.
2. Competitor - Present Bottled Water, that's source is available tap water or surface water-sources (e.g. rivers or lakes) which is treated in treatment plant of WASA or ground water sources (e.g. wells).

Need to arrange Community Based Program - i.e. Awareness of health and environment, make communities concern about drinking available surface or ground water which is contaminated with Arsenic/E.Coli/Heavy metals etc. and about root cause of water borne diseases and related illness. Also, need to know them how heavy use of ground water the ground water level is falling between 1-3 meters every year that is not a good for our agriculture (agricultural lands become barren), environment and human survivability.

So, we shall introduce the communities about Atmospheric Water and Atmospheric water's health benefits, how hygienic, safe and clean the AWG water is, compare to WASA or available bottled water or surface or tube-well water. We shall offer this technological solution AWG to the communities as Community-Based-AWG setup, it might be done through NGOs.

In near future, we shall try to introduce simple and easy, inexpensive AWG system where electricity/power will not be required. 

NO

Ten members now.

Yes, we think so - our team is the best-placed to deliver this solution to our communities. We have Mechanical, Electrical And Software Engineers. MBA and CA peoples. All they are talented. We have the capability of implementing this solution in Bangladesh.

if we get financial support and training from the expertise then we shall be able to ensure international standard of our product in respect of quality.

NO.

Who your key customers and beneficiaries are:

Water is essential for human life. So much so that the UN considers access to water a fundamental right. Part of the UN Sustainable Development Goals to achieve a better future for all is the call for universal access to clean water.

Every person needs at least 20 -50 liters of safe, clean water a day to drink, to cook with and to bathe. The world is facing a growing water crisis where half of the world's population is expected to be living in water-stressed areas by 2025. Today, over 2.5 billion people lack access to safely managed, clean drinking water. 

What product/service you provide:

Atmospheric Water Generator Technology. It uses condensation process to turn humidity into potable water. The atmosphere contains an astounding 37.5 million billion gallons of water, in the vapor phase.[2]

So we think this solution will help Bangladesh to overcome severe water crisis where Bangladesh is going to face within the next couple of decades due to random contamination of surface and ground water, absence of comprehensive water sharing with neighboring countries and mismanagement in preserving rain water. 

There are three types of model AWG here:  Residential, Commercial, and Industrial. 

How you provide it:

Let the people know about Atmospheric water's health benefits, how hygienic, safe and clean this water is, compare to WASA or available bottled water or surface or tube-well water. We can offer this AWG solution in communities as Community-Based-AWG setup through NGOs by arranging health program, seminars  etc.

Organizational Support Model is suitable

Applied to the Tiger Challenge to get Technical and Financial help thereby i will be able to set up a factory in Bangladesh to manufacture this AWG in a cost effective way and that will be affordable for my county people. As well in my factory so many county people will be employed - skilled and non-skilled workers, engineers, social workers for making the people aware of drinking safe water and save people lives etc.
