    摘要: Disclosed is a waste processing plant and method of processing waste biomass. The plant includes a waste receiving apparatus for receiving biomass waste and processing it into a liquid stream before passing it to, anaerobic hydrolysis tanks for hydrolysis, acidification and acetylation of the stream, before passing it to, a heat exchanger for raising the temperature of the stream to a pasteurization temperature, pasteurization tanks for holding the stream at the pasteurization temperature to ensure adequate pasteurization before passing it to, and anaerobic methanogenesis tanks for anaerobic digestion of a portion of the stream into biogas. Also included is a centrifugation apparatus to separate oil from the stream, wherein at least a portion of the stream which is downstream of the hydrolysis tank(s) and upstream of the methanogenesis tank(s), and which has a temperature of above 68° C., is centrifuged by the centrifugation apparatus to remove a portion of the oil.

    摘要: A reverse osmosis filtration system (100, 100A, 100B, 100C), comprising: a raw water pipeline (L1); a reverse osmosis filtration unit (10, 10A, 10B, 10C) configured to filter raw water supplied by the raw water pipeline (L1); and a faucet (30, 30A, 30B, 30C) connected to the reverse osmosis filtration unit (10, 10A, 10B, 10C), wherein the faucet (30, 30A, 30B, 30C) is operable such that a water outlet (33) of the faucet (30, 30A, 30B, 30C) is selectively in communication with a product water outflow pipeline of the reverse osmosis filtration unit (10, 10A, 10B, 10C). The reverse osmosis filtration system (100, 100A, 100B, 100C) further comprises a pump unit (50, 50A, 50B, 50C) arranged between the raw water pipeline (L1) and the reverse osmosis filtration unit (10, 10A, 10B, 10C), wherein the pump unit (50, 50A, 50B, 50C) is configured to selectively pump the raw water in the raw water pipeline (L1) to the reverse osmosis filtration unit (10, 10A, 10B, 10C) according to a pressure in the product water outflow pipeline. The reverse osmosis filtration system (100, 100A, 100B, 100C) can operate stably even when a pressure in the raw water pipeline (L1) is low, can provide the operation stability of the reverse osmosis filtration system (100, 100A, 100B, 100C), and can realize on-demand water supply for the reverse osmosis filtration unit (10, 10A, 10B, 10C).
