Potable Water


Recent independent tests carried out in the UK have proven that the patented VVF Technology can remove over 99% of cryptosporidium oocysts from fresh water without the use of chemical additives.

Cryptosporidium is a protozoan pathogen which can cause gastro intestinal illness in humans and animals. In its oocyst phase the parasite is protected by an outer shell that allows it to survive outside the host for long periods of time and makes it very resistant to chlorine-based disinfection. The cysts are round in shape and usually average 3.5 – 4.0μm in diameter.


Ingestion of these cysts causes cryptosporidiosis. Symptoms usually include; dehydration, nausea, fever, vomiting, diarrhoea, weight loss and stomach cramp or pain. Immunocompromised people may develop serious, chronic and sometimes fatal illnesses due to infection. There is no reliable treatment for cryptosporidium infection.

Cryptosporidium oocysts are frequent contaminants of water, with contributions from human and non-human hosts such as livestock, agricultural practices, infected feral and transport hosts. Several community-wide outbreaks of cryptosporidiosis have been linked to drinking water or recreational water contaminated with cryptosporidium.

The VVF Technology can be used on portable water applications to help prevent water that has been contaminated with Cryptosporidium reaching our taps. Due to its ease of application and connection into an existing system, it is ideal in emergency situations where an outbreak has been identified and where immediate removal of the protozoan is required.


The patented VVF technology has a proven record of removing manganese from potable water to levels of well below 50 ug/ltr. In doing so the technology will also prevent the build up of manganese film on the sleeves and bulbs of UV applications which can render them incapable of their purpose.

In recent uses it was noted that following the installation of the VVF technology there was no further requirement for weekly hand cleaning of the sleeves or bulbs of the UV application.
