Water Desalination: Analysis & Desalination Cost
Water Treatment & Desalination Cost
We know that over 71% of the earth is covered by water. Water clearly seems to be abundant in nature but we have a global water shortage. Why is it so, when 71% of the earth is cover by water? The primary reason is that out of the total water available on earth's surface, only 2.5% of it is freshwater. The remaining water is saline water, ice or groundwater. Humans use fresh water for consumptions and daily usage. Saline water cannot be used for the same and hence, water treatment by water desalination is bound to play a very important role in the global water crisis.
Water desalination is the process of removing salt and other minerals from saline water for the purpose of human consumption. Human beings cannot consume saline water or use it for daily purposes as well. In plain words, the conversion of saline water to fresh water can be termed as water desalination. It is important to have an analysis of the water quality for water desalination. Reverse Osmosis is one of the most popular methods of desalination these days at a reasonable desalination cost.
If you are looking for water desalination companies and desalination equipments, we at IDS Water have them all, including a wide variety of services for water testing and monitoring. Our aim is to provide you with the best services available for water related requirements. We can connect you to our clients who are well known for their products and services as water desalination companies. You can also avail water desalination equipments and other water testing kits from our network of dealers across the country and worldwide.
Reverse Osmosis (RO) Desalination
Reverse osmosis water desalination is one of the most effective processes of water treatment. It is a water purification method that uses a semi permeable membrane; a type of biological membrane that allows certain molecules or ions to pass through it by diffusion. The rate of passage of such molecules and ions depend on several factors such as pressure, concentration and temperature. An applied pressure is used to overcome the osmotic pressure in reverse osmosis.
There are many applications for reverse osmosis, which includes:
- Drinking water purification: Drinking water should be purified to the best extent possible. Reverse Osmosis (RO) is used extensively for drinking water purification. Reverse osmosis water purification system is portable and can be use for the purification of water taken from almost any source. In this process, water is pumped into the reverse osmosis water purification unit module, where it is run through a multi-media filter and undergoes ion exchange in the process. Reverse osmosis process clarifies the water and removes any particle larger than 5 micrometers. Most importantly, the process of reverse osmosis eliminates turbidity, hence, making the water appear drinkable.
- Wastewater purification: Water collected from various wastewater regions including drains, unclean ponds, natural rainwater reservoirs etc, can be reused for various purposes such as land irrigation, watering of plants and other agricultural and farming related uses. Reverse osmosis can be largely used for purposes apart from just drinking water which includes providing safe water for animal husbandry, bathing, water shows etc. The water desalination cost is also kept in a check in this way.
- Purification of water in the food industry: The food industry used a huge amount of water for various purposes such as cooking, cleaning, drinking, storing etc. Under such needs and conditions, clean and reliable form of water is essential. Hence, reverse osmosis can be used to provide services in the food industry. Reverse osmosis is used extensively in the dairy processing industry as well. While shipping, milk and other dairy products are concentrated using the RO method.
- Desalination: Reverse Osmosis is an increasingly popular method of water desalination of seawater for general public use. Reverse osmosis has relatively low energy consumption. For saline water present in saline wells and estuaries, Brackish water reverse osmosis method is used for desalination. Normally, saline wells and estuaries have water with lesser amount of salinity as compared sea water. Hence, less amount of pressure is needed to remove the salinity in such cases.
Advantages of Water Desalination & Desalination Cost
It has been a long time since the resolve to solve the problem of global water scarcity was vaunted by world leaders. In the course of time, things have made progress but there is still a lot of room for improvement and innovation. Water desalination does not come for a cheap cost. While a lot of research has been done on methods of water desalination, the desalination cost has always been a concern on the faces of researchers. Nonetheless, the process of water desalination has its benefits, which can be listed as follows:
- Relief to areas of drought: There are many places in the world where there is no access to clean water for basic human needs. In the Sub-Saharan lands of Mali and North Africa, water scarcity and drought is a serious threat to the existence of local people. The biggest advantage water desalination is that these water scarce places can avail water for their use. It offers safe and reliable source of water to such communities, which is essential for their sustenance and growth.
- Alternative source of water: The present global water scarcity situation poses serious threats to the lifestyle of people. With just 2.5% of the total water on earth being fresh water, it is necessary to have an alternative source of water. Agriculture and farming need a huge amount of water and it is from these that the distribution of food is maintained in the world. An alternative source of water can be of a huge relief to agriculture and farming and it will help in producing surplus amount of food.
- Better quality of water at places: There are many places in the world, which have fresh water supply largely, but the fresh water available over there is not safe as a lot of bacterial decomposition, algae and other water pollutants affect the water quality over there. The introduction of water desalination can provide a new source of water consumption, which offers better water quality.
- Surplus production in fresh water fishing: Fresh water fishes have always attracted people but the production of fresh water fishes is limited to places having ample amount of fresh water. With the process of water desalination, it is possible to have fresh water fish production in places where fresh water is scarce, thus giving way to ample fresh water fish production.
- Lower energy costs: Transportation of saline water makes it heavy. Thus, that results in higher cost of transportation due to more weight. Desalination process can reduce the cost of energy that needs to be moved by trucks and other transportation methods. Thus, transportation of water from the sea to places facing scarcity of water ends up being cost efficient.
So, if you are trying to find out about water desalination and desalination cost, IDS Water will provide you with all the consultation and assistance need to get the best deals. We look forward to connect you to our clients who are experts in providing water treatment and water desalination solutions and services.
