The Portable Natural Biological System (P-NBS) is the modular and mobile solution developed by AYALA Water & Ecology (Israel) for its energy-free sewage treatment technology The Natural Biological System (NBS™). The system is based on portable units design according to international dimensions of sea containers that can be transported by trucks.
Technology validated in lab.
Basic technological components are integrated to establish that they will work together. This is relatively “low fidelity” compared with the eventual system. Examples include integration of “ad hoc” hardware in the laboratory.
Selected for Testing
Selected for Testing: This innovation has been selected by BRIGAID because of its promising value for reducing the risks or the impacts of extreme hydro-climatological events. After a rigorous assessment, BRIGAID has positively approved the innovator’s testing plan, and decided to provide ongoing support for the testing activities.
We have constructed and tested the Portable-NBS at our experimental farm in Zippori (Israel) using municipal sewage that we purchase from the regional WWTP. All sewage is supplied raw and treat it onsite according to strict Israeli regulations using established electricity-free NBS technology for over 27 years. The Portable-NBS produced treated sewage at a production rate of 12 m3/day, which is the flow regime stated for unrestricted irrigation.

How does it work?

The P-NBS Is an engineered ecological system that allows natural physical, chemical and biological processes to occur all at the same time thanks to the existence of: a) Chemical-aggregates with natural or engineered minerals and active surfaces, b) Physical-gradient of substrate sizes, surface textures and porosity, and c) Biological-specialized plants and additives able to support a healthy microbiome which promotes contaminant degradation, sequestration and volatilization.
