What are the different types of water treatment systems?

The most common types of household water treatment systems consist of: 1 Filtration Systems#N#A water filter is a device which removes impurities from water by means of a physical barrier, chemical, and/or biological process. 2 Water Softeners#N#A water softener is a device that reduces the hardness of the water. A water softener typically uses sodium or potassium ions to replace calcium and magnesium ions, the ions that create “hardness.” 3 Distillation Systems#N#Distillation is a process in which impure water is boiled and the steam is collected and condensed in a separate container, leaving many of the solid contaminants behind. 4 Disinfection#N#Disinfection is a physical or chemical process in which pathogenic microorganisms are deactivated or killed. Examples of chemical disinfectants are chlorine, chlorine dioxide, and ozone. Examples of physical disinfectants include ultraviolet light, electronic radiation, and heat.

Why is chlorine added to water?

After the water has been filtered, a disinfectant (for example, chlorine, chloramine) may be added in order to kill any remaining parasites, bacteria, and viruses, and to protect the water from germs when it is piped to homes and businesses.

What happens when chemicals are added to water?

Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralizes the negative charge of dirt and other dissolved particles in the water. When this occurs, the particles bind with the chemicals and form larger particles, called floc. Sedimentation.

What is the treatment for drinking water?

Treatment for drinking water production involves the removal of contaminants and/or inactivation of any potentially harmful microbes from raw water to produce water that is pure enough for human consumption without any short term or long term risk of any adverse health effect. In general terms, the greatest microbial risks are associated with ingestion of water that is contaminated with human or animal (including bird) faeces. Faeces can be a source of pathogenic bacteria, viruses, protozoa and helminths. The removal or destruction of microbial pathogens is essential, and commonly involves the use of reactive chemical agents such as suspended solids, to remove bacteria, algae, viruses, fungi, and minerals including iron and manganese. Research including Professor Linda Lawton 's group at Robert Gordon University, Aberdeen is working to improve detection of cyanobacteria. These substances continue to cause great harm to several less developed countries who do not have access to effective water purification systems.

Because so much of the pollution that ends up in the oceans starts out on land, one way to reduce ocean pollution is to reduce pollutants in rivers and other effluent that ends up in the sea.

Lesson Summary

Many technologies are available to conserve water as well as to prevent and treat water pollution.

What is the process of removing pollutants from water?

Another natural method is called rapid infiltration, which is a process where a basin is filled with wastewater, which has already gone through a pre-treatment. The ground acts as a filter and removes the pollutants from the water. This method is similar to what happens in a septic system.

What are the different levels of wastewater treatment?

There are several levels of wastewater treatment; these are primary, secondary and tertiary levels of treatment. Most municipal wastewater treatment facilities use primary and secondary levels of treatment, and some also use tertiary treatments.

How to reduce pressure on septic system?

Following some water conservation practices can greatly reduce pressure on your septic system. For more information about conserving water, see the fact sheet about Water Consumption. Here are a few things that you can do to care for your septic system: 1 Do not use your drain or toilet as a garbage disposal; avoid putting dental floss, diapers, coffee grounds and paper towel down the drain, as they can clog up your septic system. 2 Spread your loads of laundry out over the week. When too much water is added to the septic tank, it does not have time to treat wastes, and you could be flooding your drainfield with wastewater. 3 Plant grass on your drainfield, but keep trees and shrubs away from it, because roots can clog the system and cause damage. 4 Do not drive on your drainfield, because this can compact the soil and damage the septic system components.

Why is oxygen important in wastewater treatment?

How deep are lagoons?

Shallow lagoons, that are less than 1.5 metres deep, are used for primary treatment, which allows the solid waste to settle to the bottom of the lagoon over a period of 6 to 20 days.

What is raw water treatment?

As mentioned above, the exact components of a raw water treatment system depend on the quality of water being drawn from in relation to the quality of water needed, but in general, a basic raw water treatment system typically includes some type of: chemical feed to help facilitate the flocculation or coagulation of any suspended solids.

What happens when water is coagulated?

When coagulation is complete, the water enters a flocculation chamber where the coagulated particles are slowly stirred together with long-chain polymers (charged molecules that grab all the colloidal and coagulated particles and pull them together), creating visible, settleable particles that resemble snowflakes.

Where does raw water come from?

Raw water (untreated water found naturally in the environment) can come from many sources, including rivers, lakes, oceans, or groundwater. Usually, when an industrial plant draws in the water from their surface water source, they pull it in (with pipes or by gravity) through a mesh screen or grate to eliminate the larger objects, such as twigs, ...

What is gravity settler?

The gravity settler (or sedimentation part of the raw water treatment process) is typically a large circular device where flocculated material and water flow into the chamber and circulate from the center out. In a very slow settling process, the water rises to the top and overflows at the perimeter of the clarifier, ...

What is control panel?
