Why Treat Wastewater?

It's a matter of caring for our environment and for our own health. There are a lot of good reasons why keeping our water clean is an important priority:

Wastewater treatment

The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.

What is the most widely used water treatment technology?

Many water treatment plants use a combination of coagulation, sedimentation, filtration and disinfection to provide clean, safe drinking water to the public. Worldwide, a combination of coagulation, sedimentation and filtration is the most widely applied water treatment technology, and has been used since the early 20th century.

Why is coagulation important in water treatment?

It is, however, an important primary step in the water treatment process, because coagulation removes many of the particles, such as dissolved organic carbon, that make water difficult to disinfect. Because coagulation removes some of the dissolved substances, less chlorine must be added to disinfect the water.

Why are pathogens removed from water?

Usually, the pathogens that are removed from the water are removed because they are attached to the dissolved substances that are removed by coagulation. In the picture below, the coagulants have been added to the water, and the particles are starting to bind together and settle to the bottom.

Can coagulant be added to water?

In the picture below, the coagulants have been added to the water, and the particles are starting to bind together and settle to the bottom. Coagulation jar test in a water treatment plant. As coagulation does not remove all of the viruses and bacteria in the water, it cannot produce. safe drinking water.

What is residual water?

Residuals are the by-products that remain in the water after substances are added and reactions occur within the water. The particular residuals depend on the coagulant that is used. If ferric sulphate is used, iron and sulphate are added to the water. If ferric chloride is used, iron and chloride are added.

Is coagulation safe for drinking?

What is the purpose of a water well?

Water wells are "engineered holes in the ground" that are constructed to access water that fills the cracks and pores of rocks in the earth's upper crust. This water in geologic formations is called ground water. It soaks through layers of earth and rock from rainfall and snowmelt.

Why is the water recharge process so slow?

Recharge is relatively slow because the replacement (recharge) water from rain or snow melt generally must filter down (infiltrate) slowly through the soil and rock to the ground water table.

Is ground water always free of sediment?

Most ground water moves very slowly and its long travel time in a dark cool environment means that it has few, if any, of the millions of microorganisms that are virtually always found in lakes or rivers. Ground water is usually free of sediment and constant in temperature.

Taste, odor, turbidity, and color are the principal physical properties of water that are noticed by the user. Objections are usually made for aesthetic reasons. However, these characteristics may also indicate possible health hazards or the potential for reduced operating efficiency of well equipment; and therefore should not be ignored.
