CLEAN DRINKING WATER: ENABLING DIGNIFIED LIVING

THE VULAMANZ WATER FILTER SOLVES A PROBLEM AS ANCIENT AS HUMANITY:

ACCESS TO CLEAN DRINKING WATER ENABLING DIGNIFIED LIVING

The VulAmanz Microfilter (“VM”), is a novel water treatment technology aimed at decentralized water treatment for drinking water provision and the treatment of wastewaters for recycling and reuse. It is a niche ‘fabric microfiltration’ technology developed in South Africa between University Researchers and the Specialist Fabrics Industry. The development was aimed specifically at the realities of developing economies and brings the advantages of membrane technology to developing economies. It offers significant advantages over conventional (physio-chemical) water/wastewater treatment, and over current commercial membrane technologies.

The core of the technology is a very robust woven polyester microfiltration fabric that has an effective pore size of ~ 1.3 microns (when clean). Hence the membrane is able to produce a permeate with a turbidity of < 1 NTU, and remove about three logs of bacteria. The effective pore size decreases significantly as the membrane fouls, improving the permeate quality.

The VM requires no water treatment chemicals, is gravity‐driven, extremely robust, easy to operate and maintain, and is potentially inexpensive and economically attractive. Cleaning of the fouled membrane is achieved by simply brushing the membrane, or allowing it to dry out, and no exotic chemicals are required.

 

 

THE VULAMANZ TECHNOLOGY

 

 

Uses unique, robust

WOVEN FIBRE MICRO-FILTRATION MEMBRANE

Pure water can pass through the membrane easily, but contaminants (suspended solids, colloids, bacteria etc…) cannot pass through easily.
