| Components of a Greywater Recycling System |
1. Collection Unit
The whole system first owns a collection unit. The wastewater from the building is collected and fed into a collection unit using pumps or gravity. The collection unit removes contaminants using biological, chemical, and physical actions.
2. Treatment Unit
The wastewater from the collection unit is pumped next to the treatment unit where “ultrafiltration” is conducted to remove particles, bacteria, and viruses before the next recycling stage.
3. Storage Unit
The treated wastewater is collected and stored in a designated tank. This stored water can be used as needed for toilet flushing or irrigation. However, to maintain water quality, prolonged storage should be avoided.
Types of Greywater Recycling Systems
Now, there are various variations for the greywater recycling system employed. The treatment unit can be simple or sophisticated based on the amount of greywater discharged. This shows a greywater recycling system, where the collected greywater is under a filtration treatment to avoid odor and that can be used for plant growth alone.

But here shows a treatment system, where the greywater is subjected to two ways of treatment. The water subjected to ultra-treatment is reused for toilet flushes and irrigation. While the water that undergoes only filtration is used to flourish plants.
