The Portable Natural Biological System

Small waste streams such as roadside/rail toilets, guard posts, house or small neighborhood sewage; contaminated wells and boreholes for drinking water

Developed by Ayala Water & Ecology

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.

TRL8. System incorporated in comercial design
System complete and qualified. Technology has been proven to work in its final form and under expected conditions. In almost all cases, this TRL represents the end of true system development. Examples include developmental test and evaluation (DT&E) of the system in its intended weapon system to determine if it meets design specifications. 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.

See more information about this level and the TRL and SRL levels.

The main components of the system have been tested separately, and an initial integration exercise has been conducted.

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.

Limitations/conditions under which this innovation does not work or is less effective

The P-NBS™ is robust to changes in influent water flow, however the average monthly influent should match the stated operating parameters in order to maintain the effluent quality. – – A stable platform is needed for the placement of the P-NBS™, and should be protected from incidental mishaps such as wildlife or other potential damages. – Cold weather is not a problem while the P-NBS™ is being used. If the M-NBS™ is not used during long periods of cold weather, the system will require a few days to thaw out and recover hydraulic conductivity.

Added value
• It is a mobile system made to fit on standard ground and sea transport vehicles in a single container, thus can be delivered to any location with a single truck
• There is no need for ground work infrastructure, save for a sturdy platform. This enables the client to quickly prepare for delivery and set up.
• The setup is quick and simple. The P-NBS™ arrives pre assembled and is put in place, balanced and connected with the help of a boom (on the truck) and a 2 person team.
• The PNBS™ is stable and long-lasting (30+years). It meets strict regulatory demands without the need for skilled intervention, energy or chemicals.
• The P-NBS™ enhances local surroundings and environment, providing air filtration and a pleasing aesthetic condition.
