TOP 7 WATER TREATMENT METHODS

 

By nature water is pure however, due to human behaviors, natural disasters, mixing of chemicals, water supply around the world were tend get contaminate. This brings about an undrinkable solution, since it can contain deadly bacteria and viruses, among other disease-causing agents. Luckily, mankind was able to develop different water treatment methods to allow our water supply to be safe to drink. While there are some methods that are not effective on a larger scale, all of them make untreated water potable for human consumption. Today it is important to understand why water treatment is required for domestic or industrial purposes.

 The water treatment process can be varied according to the locations, purposes and the technology used to treat polluted water.

 

Coagulation / Flocculation

Coagulation is adding liquid aluminum sulfate or alum and/or polymer to raw or untreated water. The resulting mixture causes the dirt particles in the water to coagulate or stick together. Then, the groups of dirt particles attach together, forming larger particles named flocs that can easily be removed via filtration or settling.

 

Sedimentation

When water and flocs undergo the treatment process, they go into sedimentation basins. Here, water moves slowly, making the heavy floc particles settle to the bottom. Floc that accumulates on the bottom is known as sludge. This is carried on to drying lagoons. Direct Filtration does not include the sedimentation step and the floc is just removed by filtration.

 

Filtration

In filtration, water passes through a filter, which is made to take away particles from the water. Such filters are composed of gravel and sand or sometimes crushed anthracite. Filtration gathers together impurities that float on water and boosts the effectiveness of disinfection. Filters are regularly cleaned by means of back washing.

 

Disinfection

Before water goes into the distribution system, it is disinfected to get rid of disease-causing bacteria, parasites and viruses. Chlorine is also applied since it is very effective.

 

Sludge Drying

Solids that have been gathered and removed from water via sedimentation and filtration are transferred to drying lagoons.

 

Fluoridation

Fluoridation treats water supplies of communities to adjust the concentration of free fluoride ions to an optimal level so that dental cavities can be reduced. It is compulsory for Hunter Water to perform water fluoridation to conform to the NSW Fluoridation of Public Water Supplies Act 1957.

 

pH Correction

To adjust pH levels, lime is combined with filtered water. This, also, stabilizes naturally soft water so corrosion can be minimized in the water distribution system and plumbing of customers.
