摘要： A process a system for treatment of an input gas are disclosed. The input gas (e.g. biogas) comprises carbon dioxide. First and second gas-liquid contact stages each comprise one or more gas-liquid hollow fibre membrane contactors permeable to carbon dioxide, each with a gas side and a liquid side. The input gas flows through the gas side of the first gas-liquid contact stage. A first carbon dioxide absorption solution, comprising ammonia, is circulated through the liquid side of the first gas-liquid contact stage, to absorb some of the carbon dioxide from the input gas to leave an intermediate gas flowing out of the first gas-liquid contact stage. The intermediate gas flows through the gas side of the second gas-liquid contact stage. A second carbon dioxide absorption solution, comprising ammonia, circulates through the liquid side of the second gas-liquid contact stage, to absorb carbon dioxide from the intermediate gas to leave an output gas flowing out of the second gas-liquid contact stage. The process is controlled so that more precipitation of ammonium bicarbonate occurs in the first carbon dioxide absorption solution, per unit volume of first carbon dioxide absorption solution, than in the second carbon dioxide absorption solution, per unit volume of second carbon dioxide absorption solution.

摘要： A gas treatment assembly for controlling the CO 2 /CH 4 ratio of a gas stream (generally from a biogas unit) to make it more suitable as input for a combined heat and power (CHP) system uses a treatment module (10) in which the gas and a treatment liquid pass in contraflow, separated by a membrane (18). Generally the membrane has the form of a bundle of tubes, with one flow path passing through the interiors. The membrane is selected to allow passage of the gas (or a part thereof) but to resist passage of the liquid. It may be microporous and hydrophobic.

摘要： System and method for a urine and wastewater treatment are described. The urine and wastewater treatment system can include a tank configured to receive liquid waste (102), an air blower (114) configured to blow air into the liquid waste to reduce the density of the liquid waste and to generate crossflow, and a filtration unit comprising an ultra-filtration stage (104) comprising a first permeate outlet and a first concentrate outlet and a reverse osmosis stage (112) comprising a second permeate outlet and a second concentrate outlet. The reverse osmosis stage is configured to receive a first permeate from the ultra-filtration stage.

摘要： Particles in a liquid flow are monitored by reflected light fluorescence. The flow may pass through a flow cell (10) having a viewing window (14). The flow cell may be partitioned by a membrane (12) so that deposition of particles can be monitored. The use of reflected light fluorescence enables the monitoring of small particles (under 3ųm) which are important in the fouling of membrane surfaces in membrane bioreactors, but which are undetectable by conventional direct observation methods.

摘要： A non-sewered toilet system and method for separation and treatment of human waste are described. The system can include a frontend system with a solids separator (100), a buffer tank separation system (200), a liquid waste treatment system (300), and a solids waste treatment system (400). The solids separator (100) can separate combined human waste including feces or urine into a separated solids portion and a separated liquid portion. The buffer tank separation system (200) can deliver a solids portion of the input stream to the solids collection tank and deliver the liquids portion to the liquids collection tank. The liquid waste treatment system (300) can receive liquid waste collected in the liquids collection tank and deliver a usable water. The solids waste treatment system (400) can receive a slurry from the solids collection tank, heat the slurry in a reactor to a temperature that is at or above the critical point of water to inactivate pathogens.

摘要： Non-sewered toilet system and method for separation and treatment of human waste are described. The system can include a frontend system with a solids separator (100), a buffer tank separation system (200), a liquid waste treatment system (300), and a solids waste treatment system (500). The solids separator can separate combined human waste including feces or urine into a separated solids portion and a separated liquid portion. The buffer tank separation system can deliver a solids portion of the input stream to the solids collection tank and deliver the liquids portion to the liquids collection tank. The liquid waste treatment system can receive liquid waste collected in the liquids collection tank and deliver a usable water. The solids waste treatment system can receive a slurry from the solids collection tank, heat the slurry to inactivate pathogens, and form feces cakes with a filter press. A combustor can reduce the feces cakes to ash.
