Laboratory Services

We can carry out jar testing to identify:

• the most cost effective activated carbon for your situation
• the required dose of PAC to achieve a certain level of compound removal.

It would be tested on your water and under the specific WTP conditions you will be using it in.

In addition to the standard production tests, We have a highly sensitive Potable Water laboratory capable of conducting analysis of:

• dissolved organic carbon (DOC)
• biodegradable dissolved organic carbon (BDOC)
• UV absorbance scans for characterisation of organics

These facilities allow us to optimise our products for the Potable Water industry. In addition, we can provide technical support for our customers, such as optimisation of ozone dose and BAC operating conditions. This is a unique and valuable testing method that we offer all our customers.

We carry out aging analysis on GAC/BAC samples from Potable Water treatment plants. This thorough set of analyses includes:

• mineral composition
• particle size evolution
• activity decay

This information is crucial to predict the bed life of the carbon and assists in identifying any process problems that may have been going on unnoticed.

As part of our product development programs for activated carbon used in Potable Water treatment we routinely perform leachate testing. This research ensures that we know how to achieve an activated carbon product that:

• has no floaters
• has no pH effects and
• contributes no water soluble leachates during the commissioning process.

By using a laser defractometer we can with extreme precision determine the particle size of our PAC products. It is used both as a quality control in production as well as for evaluating different carbon applications and performances.

We have been undertaking special trials in close cooperation with Coca Cola Amatil in carbon optimisation studies. The goal is to provide the best carbon for removing chloramines and disinfection by-products after super-chlorination.

We carry out gold adsorption kinetic testing and sugar decolourising trials. The outcome of these trials will assist in selecting the most suitable carbon for a specific application.
