Plasma Water Sanitation System

The Plasma Water Sanitation System (PWSS) is an innovative water treatment system that eliminates 100% of virus and bacteria through the transformation of a continuous flow of contaminated water into plasma. Through a sharp pressure drop inside the reaction chamber, the water is transformed into biphasic liquid-gas stream. The biphasic flow is exposed to an electrical current field that ionizes the water particles generating a stable plasma state; subsequently, the water elements are recombined and condensed as potable water suitable for human consumption.

Microorganisms are impacted by a series of phenomena typical of the plasma state such as: Plasma thermal effect, ionization, irreversible electroporation and genetic material rupture.

The first of multiple possible applications of this technology, the PWSS Camp Unit, developed wholly by Advanced Innovation Center, is a distributed solution of high energy efficiency and low operational cost. It is specifically designed for the decentralized Production of potable water in communities that today lack a safe water source.

A Camp Unit can produce 2,500 liters of potable water per day, with ease of operation and maintenance, enough to satisfy the basic needs of 125 people.

The system is designed to efficiently accept additional filters such as reverse osmosis, activated carbon, retro-wash and chlorine treatment in accordance to other regulatory needs.

Specifications

• 1 Camp Unit contains 2 PWSS units
• PWSS technology eliminates 100% of virus and bacteria. Other contaminants that may be present in the water may be removed through complementary conventional treatment and filtering stages that may be applicable to the source water and local regulations.
• Two PWSS Units can supply the demand of 250 persons based on 20 l/day per person daily consumption.
• Equipment cost: US$50,000 per Camp Unit (2 PWSS units). The cost is within acceptable ranges for the IDB for these types of solutions (US$1,000 – 1,500 per family).
• Delivery and installation costs: Location specific.
• Operating costs: Location specific, local electric power cost dependent.
• Dimensions Camp Unit: Length: 3 m Width: 2.4 m Height: 2.5 m
• Power: 3kW.
• Units are outfitted with telemetry and automatic control systems.
• A set up and follow up control stage is considered for pilot units.
