How is water recycled and reused?

Water reuse (also commonly known as water recycling or water reclamation) reclaims water from a variety of sources then treats and reuses it for beneficial purposes such as agriculture and irrigation, potable water supplies, groundwater replenishment, industrial processes, and environmental restoration.

What type of treatment makes reuse water potable?

There are two types of potable water reuse: Indirect potable reuse: Uses an environmental buffer, such as a lake, river, or a groundwater aquifer, before the water is treated at a drinking water treatment plant. Direct potable reuse: Involves the treatment and distribution of water without an environmental buffer.

Water recycling is helping us achieve planetary sustainability in many ways. We tend to forget that sources of potable water on our planet is limited, less than 2% of the water on our planet is fresh water, including glaciers and polar ice caps. The goal is to substitute recycled water where potable water is unnecessary. For example, we can use recycled water to recharge underground aquifers, irrigate landscapes and crops, and flush toilets. By using recycled water more frequently we can sustain the limited supply of potable water for drinking and cooking.

The settled blackwater is then diverted ...

How often should I service a blackwater treatment system?

Owning a blackwater treatment system doesn’t pose any serious problems that we’ve noticed so far. It’s serviced every 3 months by the company that installed it. We do need to be careful of what we send down our drains as chemicals and anti-bacterial products can destroy the bacteria colony; but that’s been a good thing as it means we use more environmentally friendly products.

How does aeration work?

The result of the aeration stage is then piped into a sludge settling chamber. Sludge sinks to the bottom and partially treated water is forced upwards through a mechanism that has another bacteria biomass covering it. This colony of bacteria then consumes most of the oxygen in the mix and breaks down any remaining solid particles.
