Hi Shawn,
A simple system commonly known as a laundry to landscape system could be optimised to industrial scale if need be. Laundry water either for reuse in Laundry or for use in irrigation.
The laundry to landscape system allows for a limited number of trees and shrubs to be irrigated by utilizing the built-in pump within the washing machine. The water pumped from the washing machine is unfiltered and is simply dumped onto the plants and trees. Valves are added to provide some flow balancing to the system. Because the greywater is unfiltered it is mostly not used in drip irrigation systems.
Also, using ozone has over time proven to be inefficient and expensive especially on a large industrial scale as for oxidizing these soluble pollutants. Use of biological treatments is presently gaining sway and is most sustainable for this process.

Hi, Amali, Could you please indicate studies on "using ozone has proven to be inefficient..."? Expensive, yes, I admit, but inefficient.?, Where are the facts based on data?

Hi Pedro.
I am not an expert in this field but it is of concern to me and I have had to read lots of related literatures assessing the system functionality. The efficiency of the system often comes into question due to the need to maintain an optimal ozone dosage. Low dosage may not effectively inactivate some viruses, spores, and cysts. And because the concentration of ozone generated from either air or oxygen is so low, the transfer efficiency to the liquid phase is always a critical economic consideration.
