Validating AOx Effectiveness

Introduction

This is a program to validate and quantify the efficiency of OriginClear’s patent-pending Advanced Oxidation Process, AOx™, in removing Persistent Organic Compounds that are found widely in tap water, and many bottled waters as well.

We call these compounds microtoxins, because even in low doses, many have the potential to affect the immune and endocrine systems in humans and animals.

There is a wide array of these compounds. This program focuses on the most widely-known microtoxins. We will continue to publish results of our testing as it progresses.

We follow best practices for scientific sampling. While interim readings may be taken in-line or using quick-result test kits, a certified laboratory is called in to analyze the results of each major test before it is published.

Method

We implement AOx in two proprietary designs, implementing two kinds of electrochemical reaction to degrade microtoxins. These are Direct Oxidation (DO), and Indirect Oxidation (IO).

We deploy both reaction types for each compound we test, to benchmark relative efficiency. Our systems in the field typically implement a combination of Direct and Indirect Oxidation. We have observed a significant synergistic effect from this combination, potentially boosting results further in operating conditions.

For DO, we use a lab-scale reactor set using our patented inline reactors. We place the sample into a holding tank, feeding into the reactor for a controlled period. We perform successive runs to model larger scale systems. Typical treatment time per run is three minutes though we have proven shorter run time with great success.

For IO, we use a lab-scale static tank where we place electrodes in a mesh configuration lining the bottom of the tank. This creates a gaseous cloud in the water. In our dirty-water systems, we use this process as a flotation method to extract suspended solids and oils. In this instance, the water remains clear, since we are working with drinking water. Typical treatment time can vary between 30 minutes and 90 minutes.

This process occurs in real time, as we are able to deploy an array of tubes to achieve suitable residence time, and we have the synergy of DO and IO when operated in sequence.

Procedure

We create a sample solution which may be artificially high in contaminants (approximating typical animal testing), or in concentrations found more typically in our drinking water.

Direct Oxidation

The static tank is filled with the test solution. We then pump the solution into the reactor inlet, and we control flow to obtain a three-minute residence time in the reactor. The effluent is typically run through the reactor again several times, to approximate real-world results at scale, where very long reactor tubes provide lengthier, and therefore more effective, residence time.

Indirect Oxidation

A 1-litre reactor cell is filled with the sample solution. The gaseous cloud is generated. During the 60-minute test, samples are taken every 15 minutes.

The Test Series

OriginClear is conducting tests on a variety of contaminants present in drinking water at a microtoxin level, beginning with glyphosate, the key ingredient in Monsanto’s Roundup® and many other commercial herbicides. Reports on the full test series follow.
