Contaminants and debris in greywater can pose health risks and damage plants, so effective filtration is essential to ensure the water is safe and suitable for use.
There are two main types of filtration systems: biological and physical.
Biological systems use living organisms to break down organic matter and remove contaminants, while physical systems rely on mechanical processes to filter out solids and other impurities.
Physical systems can include sedimentation, sieving, and screening processes, while biological systems may utilize bacteria, fungi, or other microorganisms to break down organic matter.
Depending on the specific needs and limitations of your project, you may choose to use a combination of both biological and physical filtration systems to ensure the best results.
By properly selecting and implementing a filtration system, you can effectively remove contaminants and debris from greywater, making it safe for use in irrigation, toilet flushing, and other non-potable applications.
Design and build the system
Once you have your collection and filtration methods in place, it’s time to design and build your system. This may include pipes, pumps, and storage tanks. Be sure to consider the size and capacity of your system, as well as any necessary safety features.
