The Importance of a Multi Level Water Recycling System

In addition to the economy, wastewater recycling is of utmost ecological importance.

When we talk about recycling, we soon think of aluminum cans, glass bottles and newspapers and everything else, but water can also be recycled. Water recycling is a reuse of treated wastewater for purposes other than direct consumption, such as agricultural use and landscape irrigation, industrial processes such as washing and cooling machinery, discharging toilets and refilling basins of groundwater, among other applications generally for non-potable use, is very important in several aspects.

Recycling water is an important means of saving both financially and ecologically and can be applied on a large scale, such as in industries or on smaller scales, such as in your own home through water recycling systems such as rainwater harvesting.

Applications of the Result of a Water Recycling System

We can replace drinking water from public water networks using a water recycling system, which we usually use for non-consumer uses, for recycled water, for agriculture, irrigated outdoor & landscaping, or public places such as parks. Other non-durable applications of a water recycling system include cooling water for power plants and oil refineries, industrial process water for installations such as paper mills and carpet paints, flushing cleaning, dust control, construction activities, concrete mixing and artificial lakes.

Water is sometimes recycled and reused in the same place, for example, when an industrial facility recycles the water used for cooling processes or collecting rainwater. A common type of recycled water is water that has been reclaimed from municipal sewage or sewage.

Indirect Reuse in a Water Recycling System

Wastewater treatment can be tailored to meet water quality requirements. Recycled water for landscape irrigation requires less treatment than recycled water for consumption, as it maintains a high concentration of organic matter and mineral salts, using only the removal of pathogenic factors and toxic elements and meeting the needs of plants.

Although most water recycling systems have been developed to meet the demands of non-potable water, several projects use indirectly recycled water for potable purposes. These projects include a recharge of groundwater aquifers and the increase of surface water reservoirs with recycled water. In groundwater recharge projects, recycled water can be disseminated or injected into aquifers of groundwater and groundwater to increase groundwater supply and prevent intrusion of salt water into coastal areas.

Types of recyclable water

Grey water

Gray Water is the generic term given to the water of showers, bathtubs, laundries and bathroom sinks in your home. Properly treated by a water recycling system, this water can now be recycled and reused for irrigation of interiors and landscaping and discharges of toilets.

Black water

Blackwater is the term used for biological wastewater, such as the public sewage collection network. This water can and should be treated before returning to the natural stream, before returning to rivers and aquifers.

This type of wastewater recycling is much more complex, and has large-scale and long-term planning, targeting the entire ecosystem and the path of these waters. Using various chemical and physical processes, the treatment of these waters is essential to avoid the pollution of the environment by biological waste.
