The present invention relates to delivering sample preparation technologies to enhance the performance of point-of-care agricultural diagnostics by improving the capacity to detect trace contaminations of pathogenic organisms along the entire food supply chain including pre- and post-harvest processing and distribution. Sample preparation is crucial for adequate test performance of downstream diagnostics like LAMP and supports sensitive detection of bacterial contaminates. This invention increases the speed and scale of routine pathogen surveillance and the efficacy of management response and mitigation of foodborne disease outbreaks.

The invention relates to a system and to a method for purifying faecal-free and surfactant-containing domestic wastewater, in particular grey water and kitchen wastewater. An electrochemical treatment unit (3) and a device for introducing gas (11, 12, 14) are provided. Furthermore, at least two dirty water tanks (1, 21) are present, wherein domestic wastewater to be purified is fed to the first dirty water tank (21) from at least one first consumer, and wherein domestic wastewater to be purified is fed to the second dirty water tank (1) from at least one second consumer. In addition, at least two clear water tanks are present, wherein the purified domestic wastewater originating from the first dirty water tank is fed to the first clear water tank (22), and wherein the purified domestic wastewater originating from the second dirty water tank is fed to the second clear water tank (6).

A process for removing oil and other organics, especially naphthalenic acid, is disclosed. The process involves use of electrical fields using electrodes in the device, inducing gas bubbles which force contaminants to the surface of the solutions to be skimmed off and recovered.

A process for treating a source fluid in a manner that results in converting a carbon constituent into a carbonate constituent. The process includes the steps of providing the source fluid to a first treatment step, the source fluid being aqueous and comprising: at least one ppm to no more than five percent (by volume) of a hydrocarbonaceous component, and an impurity that includes a metal, a hard mineral, and combinations thereof. The process includes reacting the source fluid via the first treatment step to produce a treated aqueous stream comprising at least one percent to no more than thirty percent (by volume) of a hydroxide constituent.

A water treatment equipment includes a reaction chamber, a waveform generator, and a controller. The reaction chamber includes a pipe having a first electrode and a second electrode. The first and second electrodes are coupled to a waveform generator. The reaction chamber includes a water inlet, and a water outlet. The waveform generator is coupled to the first and second electrodes. The waveform generator is configured to generate an electrical current with a frequency that is substantially equal to the electrical resonance of the pipe of the reaction chamber. The controller is configured to control the waveform generator, wherein the reaction chamber is configured to enable a flow of ozone and water to be treated through the pipe.

A method and device is provided for combining various forms of flotation techniques to achieve a very high degree of purification of waste water while energy consumption is maintained low.
