The offered method of water purification is based on the photocatalytic degradation of contaminations. Photocatalysts are received as a results of the modification of layered nanoclays by polymers that can absorb both visible and ultraviolet light. Experimental tests have shown that hybrid photocatalysts may efficiently degrade water pollutants as a result of oxidation by singlet oxygen energy or electron transfer. Morover it has been proved that hybrid photocatalysts have the ability to adsorb hydrophobic compounds thereby additionally improving the water purification process.
An integrated acid mine drainage (AMD) solution has been developed using a combination of biological and chemical treatment steps to produce desalinated water fit for reuse or discharge. This process produces a smaller volume of solid waste when compared with conventional lime or limestone neutralization processes and offers the opportunity to extract valuable by-products such as elemental sulphur calcium carbonate pellets and magnesium hydroxide
A versatile point-of-consumption water treatment bottle has been developed that allows users to process untreated water (without a pump system) using different chemicals or filter components found in a typical household. This allows the user to easily adapt the treatment to what is available rather than having to buy specific replacement components thereby ensuring consistent use over longer periods in remote areas
A carbon nanotube-infused filtration membrane for higher throughput filtration of oil-containing wastewater. The structure of the membrane reduces fouling and increases mechanical strength thereby increasing filter lifespan and and enabling cheaper wastewater filtration. The membrane has application in industries needing to manage the disposal of oil-water emulsions such as oil fields metallurgical pharmaceuticals and petrochemicals.
A fluidised bed bioreactor which uses thermophilic bacteria to remediate industrial municipal or agricultural wastewater to potable water without requiring pre-cleaning. The bioreactor simultaneously produces energy in the form of biohydrogen and biomethane during the water treatment process
This Algae pilot is the first of its kind in Sweden. The algae convert unwanted substances to utilities. The goal is that algae cultivation will reduce our emissions of carbon dioxide and purify waste water to minimize over-fertilization of our waters and at the same time produce an energy-rich algae mass that is raw material for biodiesel (algae with high fatty acid content), animal feed (protein-rich algae) etc.
