Das Numen H20 is a modular system and research on biological sustainable water purification mechanisms aiming to provide free drinkable water from

local water resources and an aesthetic moment in cooperation with nature triggering contemplation and reflection on water related issues like water pollution

and waterpotability criteria, water prepa- ration, water availability, water monopolism and water privatisation processes.

 

The modularity of the system aims to be adaptable to new site specific challenges, like the different climate condi- tions, the individual pollution cocktail of

water and the energy resources found on the venues of its installation. This process of local adaptation offers invention potential for new filter steps to be

developed. So to say the setup and design wants to change due to the site specific needs, the modular system is confronted with. Its feedback triggering

research and development.

Mycelial Biofilter System

 

The announcement and implementation of a diploma thesis on the issue is intended as the field of mycofiltration is a relatively new and exciting field for scientific

research. One of the primary roles of fungi in an ecosystem is that of decomposition of organic compounds. Petroleum products, pesticides and herbicides, that

can be contaminants of soil, are organic molecules. Fungi therefore have potential to remove such pollutants from the soil environment, a process known as

bioremediation.

Mycelial mats have been suggested (see Paul Stamets/ Growing Gourmet and Medicinal Mushrooms) - as biological filters, removing chemicals

and microorganisms from soil and water. The use of fungal mycelia to accomplish this has been termed ÒmycofiltrationÒ.

The shell of D. polymorpha is triangular - or triagonal with a sharply pointed shell hinge end (umbo). The maximum size of D. polymorpha can be 5

centimetres, though individuals rarely exceed 4 cm (Mackie et al. 1989). Its most obvi- ous characteristic is the prominent dark and light banding

pattern on the shell which may be either smooth or zigzag in shape. The outer covering of the shell is generally well polished.

 

These mussels are filter feeders; they use their cilia to pull water into their shell cavity where it passes through an in- current siphon and it is

here that desirable particulate matter is removed. Each adult mussel is capable of filtering one or more liters of water each day, where they

remove phytoplankton, zooplankton, algae, and even their own veligers (Snyder et al., 1997). Zebra mussels are able to filter particles smaller

than 1μm in diameter, although they preferen- tially select larger particles (Sprung and Rose 1988). Thus bacteria may represent an important

ood source (Cotner et al. 1995, Silverman et al. 1996). Any undesirable particulate matter is bound with mucus, known as pseudofeces, and

ejected out the incurrent siphon. The particle-free water is then discharged out the excurrent siphon.

The Department of Sanitary and Environmental Engineering (DESEE) at University of Kassel developed a small, transportable and easy-to-use

drinking water unit based on membrane technology which is able to supply a group of 200 – 500 people with a minimum daily drinking water

demand of 7 liters per person. In remote regions and cases of disaster neither electricity nor chemicals for disinfection are available, thus a

gravity-driven microfiltration membrane was chosen to generate drinking water under these circumstances. The unit can be operated by

everyone meaning not only especially skilled and trained personnel.

 

We support the sustainable nature of easy-to-use, little energy consuming and almost no technical support demanding devices, thus are using

the same kind of gravity-driven microfiltration membrane system that is used in the described invention of the University of Kassel. Its design

will be especially adapted to our needs. As the last component of our modular filtration chain it will cleanse the biologically pre filtered water to

the quality of drinkable water.
