With this new plant, Katara Cultural Village will save between 5,000 and 15,000 cubic meters of fresh water per day. In recent months, Veolia has also opened significant wastewater treatment and reuse plants in France and […]

Sanitation District is the site of the first installment, at a commercial facility, of a new supercritical water oxidation (SCWO) technology capable of producing clean water and minerals from waste slurries. The clean-technology startup 374Water Inc., originating from Duke University, developed the technology, known as AirSCWO.

Membrane developer ZwitterCo says its membrane is fouling-immune in cases where fouling of membranes by natural organic matter necessitates frequent membrane cleaning. By enabling restoration of membrane performance by simple water flushing, the new membrane reduces maintenance downtime and lengthens membrane lifespans.

The technology separates, dries and sterilizes solid material from a liquid slurry, while recovering valuable nutrients, in a single step. Outputs of the process are pathogen-free solids (class A-EQ depending on the application), along with a concentrated aqueous solution of nutrients, such as ammonia, that can be used as feedstock for agricultural fertilizer manufacturing, and clean water for reuse.

The primary goal of these regulations is to prevent contaminants and toxins that are present in bioprocessing-facility wastewater from entering sources of drinking water, which then must be treated by municipal water-treatment plants. An additional emerging area of interest focuses on water reuse — for both regulatory reasons and economic ones — because the cost to treat and reuse some wastewater can be far less than the cost of starting with untreated water.

This technology, originally characterized and developed at the University of Birmingham and commercialized by spin-off company Salinity Solutions, is said to use 50% less energy and generate 80% less waste than conventional RO, while purifying up to 98% of the water.
