摘要： PROBLEM TO BE SOLVED: To provide a desalination apparatus and a washing method of a pretreatment membrane of the desalination apparatus which can efficiently remove scale and extend back washing intervals.
SOLUTION: The desalination apparatus includes a pretreatment device 13 having the pretreatment membrane 12 removing turbid matter in raw water 11; a reverse osmosis membrane device 17 having a reverse osmosis membrane (RO membrane) 16 removing salinity from filtrate 14 from the pretreatment device 13 to produce fresh water 15; a fresh water back-washing line 30 feeding the fresh water 15 produced in the reverse osmosis membrane device 17 to the pretreatment device 13; and a chlorine feed part 32 feeding chlorine 31 to the fresh water back-washing line 30. The fresh water 15 is used for back-washing of the pretreatment membrane 12.

摘要： PROBLEM TO BE SOLVED: To lower the loss by conversion to electric power and improve the energy efficiency by driving a pump, which pumps up sea water, by transmitting driving force of a driving source through a transmitting means to the pump and driving a power generator by the driving force transmitted through a transmitting means. SOLUTION: A diesel engine 4 which is a driving source of this water producing apparatus 1 is connected with a power generator 5 and a high pressure pump 6 through a clutch 3 and the clutch 3 selectively drives either the power generator 5 or the high pressure pump 6 by switching operation. That is, the high pressure pump 6 is driven by a diesel engine to operate the water producing apparatus 1 and by switching the clutch 3, the power generator 5 is driven by the diesel engine 4. To carry out water producing treatment, sea water 7 is pumped up by the high pressure pump 6 and desalinated by a reverse osmosis membrane 8 to obtain drinking water 9. On the other hand, in the case that the power generator 5 is driven, the driving force of the diesel engine 4 is transmitted to the power generator 5 and obtained electric power is sent to heaters and luminaires 11.

摘要： PURPOSE:To provide an apparatus and a method for treating drainage in which the concentration of solid components is relatively low, a large amount of drainage is treated efficiently with compact equipment, and troubles including blocking in a piping system hardly occur. CONSTITUTION:Drainage to be treated is received in a drainage vessel 1 for the sedimentation of solid components. The supernatant in the drainage vessel 1 is discharged by a supernatant draw line 5 to concentrate the drainage in the drainage vessel 1. The concentrated drainage in the drainage vessel 1 is agitated by the air discharged from a bubbling pipe 2 and is led into a separation-dewatering machine 8 through a concentration line 7. The filtrate, after the solid component being separated by the separation-dewatering machine, is returned to the drainage vessel 1 through a reflux line 9.
