Water Use & Availability
Prolonged drought, water shortages and concerns for our health have changed forever the way Australians think about water – no more so than in the fast growing area of South East Queensland. Not so long ago we assumed the water out of our taps was OK if it looked clean and didn’t smell too bad.
With global connections through the internet and information becoming more readily available – people are starting to ask questions about their water.
- Will we have enough water into the future?
- Where does our water come from?
- How safe is it to drink?
Governments implement strategies around the sources and supply of water.
Agriculture and industry consume large quantities of water and are looking to minimise usage.
Householders also want to minimise use and are concerned about its quality and how to improve it.
That’s where we come in. Total Water Solutions provides a comprehensive range of products, advice, and analytical and consulting services; aimed at optimising the use of our most precious of resources.
Why Purify Water?
Understanding the qualities of water will help answer this question.
Water is like a magnet. When it comes into contact with other substances, it readily absorbs them. That means as rain water moves through our environment, it can pick up harmful substances which are then drawn into our water supply – for example air pollution or toxic chemicals in the ground. Without filtration, we end up drinking these substances and bathing in them. Water can also damage or cause corrosion to pipes and appliances.
Water quality is affected by:
- the occurrence of natural elements like minerals in the soil
- intended additives – chlorine/fluoride
- accidental additives – pollution from mining or agricultural activities, leaching of surrounding soils or airborne pollutants
The science to analyse water problems and the technology for solving them have made rapid advances in recent times. So whether it’s domestic drinking/household water or industrial/commercial water, there are solutions to water purification and efficiency in water usage.
Water comes into our homes from different sources – each having a unique set of characteristics.
Tank water collected off your roof through gutters and downpipes, is open to a variety of contaminations: from chemical pollutants in the city, through to leaves, dirt and animal droppings. In some areas … Continue reading →
Town water originally comes from a variety of sources. Water authorities set up catchment areas that trap the water running above and through the ground. It then sits in large dams waiting to be used. Town water is known as a … Continue reading →
For those who are technically minded, we thought to include some interesting information about the carbon filtration process.
How does carbon filtration work and what is the process in making a carbon filter?
Carbon actively filters water, not only through grain size, but also by its ability to bind organic and inorganic materials to itself through an electrical charge on its surface – a process known as adsorption.
Carbon filtration is used for filtering wastewater and removing fine insoluble, metals and chlorine compounds from domestic water.
There are several types of carbon produced for differing filtration needs.
Activated carbon is made from any organic material containing carbon. Commercial carbons are made from sawdust, wood, charcoal, peat, lignite, petroleum coke, bituminous coal, and coconut shells.
We choose these raw materials in order to provide the best activated carbon to our customers.
The coal is pulverized to very fine particles like talcum powder. The powdered coal is mixed with a binder to “glue” it back together. Then it’s pressed into briquettes. These are then crushed and classified to the size of the desired end product. This process, called reagglomeration, creates a uniformly activated carbon that is harder and less dusty than the original product.
The sized material is heated in an oxygen void environment to remove the volatile components of the coal. The carbon is then activated by additional heating in a controlled environment of oxygen and steam. The activation process creates a highly porous graphitic plate structure with tremendous surface area.
Another way to visualize this is: If you had a 200 litre drum full of dry carbon, you could add 166 litres of water to the drum before it would overflow. Therefore, 80 percent of the drum volume is air.
The pore space is the internal volume of the carbon granule. It consists of all the cracks and crevices created when the coal is crushed and glued back together, and the volume between the graphite plates. The distance between the graphite plates determines whether the space is an adsorption pore or a transport pore.
That’s the process for getting the carbon filter made. What happens when that carbon filter is introduced into a water filtration system?
