The importance of aeration for superior water treatment

Water treatment is essential for keeping all bodies of water clean, whether this is an ornamental lake, small pond or a council or industrial wastewater plant. The most common water treatment technique is aeration that can be achieved using anything from small pond pumps to much larger aeration pumps.

Aeration keeps water bodies clean by adding air into the water column, promoting aerobic biodegradation of any organic pollutants by microbes that flourish in aerated water. Most people with a fish tank or backyard pond already understand the importance of using a simple pond cleaner that circulates air within the water. People tend to forget however, that aeration can be just as necessary in larger bodies of water, particularly in waste water treatment plants, because it helps to reduce the amount of organic matter in the water.

Aeration is an environmentally friendly type of water treatment

No-one wants to add lots of chemicals to fresh water bodies, whether this is their backyard fish pond, a beautiful lake or a dam on their property. Reducing our environmental impact is important for everyone and water treatments using aeration comes out tops for being the cleanest type of treatment available.

Aeration works because the circulated air contains oxygen that is used by the bacteria in the water to degrade organic matter. As the organic matter is broken down it forms carbon dioxide and water, which is obviously harmless. This added oxygen also helps to keep fish and other freshwater creatures alive in the water, maintaining a healthy ecosystem and is another reason why pond cleaners are so important.

However, if the water is not aerated, the microbes can’t break the organic matter down fast enough and it starts to build up and form a sludge at the bottom of the pond or lake. The organic matter is still broken down by the bacteria, but it is much slower in the absence of sufficient oxygen and leads to the release of carbon, hydrogen and sulphur that combine to produce hydrogen sulphide and methane.

This results in a lowering of the water’s pH, creating acidic conditions, a rotten egg smell to the water and the death of fish and other creatures that live in the stagnant water. All of this can be prevented by using pond pumps or larger water treatment devices that simply circulate air through the water.
