Grander Technology
at a textile-dyeing factory
At the Polytechnical University in Hong Kong graduate student Wong Siu Kuen examined the application of Grander Technology in textile dyeing factories, which often find it difficult to comply with environmental regulations and operate in a very competitive business sector.
Before a textile product can be sold, it must be subjected to dry and wet treatments. Experts know that with the wet treatment the quality of the water has a decisive effect on the quality of the final product. The quality of water in Asia is often quite bad, and one attempts to compensate for this by the addition of chemicals such as metal masking products, anti-chlorine products or resin treatment. The dosage of these chemicals must be calculated exactly as otherwise there is the risk of dyeing faults with a consequent inability to reproduce the products correctly.
The study examines whether water revitalised using Grander Technology behaves differently from local tap-water and whether it is possible by its use to reduce the environmental impact and costs.

A summary of the results: “Introducing the revitalised water system is a breakthrough for textile wet treatment, because the revitalised water improves the effectiveness of the process. The most important point for the manufacturer is that the revitalising process does not result in any by-products, and there is no need for electric power, filters or chemicals.
In other words, the installation of a revitalised water system is the sole initial investment necessary, and the system proves itself to be advantageous for the factory from the moment it is installed. |
