PROBLEM TO BE SOLVED: To provide a water treatment apparatus which is compact and portable. SOLUTION: When an operation handle 29 is turned, rotational force is transmitted from a first step planetary gear mechanism 10 to a second step planetary gear mechanism 11 while the speed of the force is increased multi-stepwise, a pump shaft 27 is rotated in each pump chamber 34 and 35, and raw water is supplied to a RO module 2. The raw water supplied to the RO module 2 permeates the reverse osmosis membrane in the module to be cleaned. Concentrated water by the RO module 2 is introduced in turn from a faucet part 6 (raw water discharge opening) to a concentrated water introduction passage 41 by way of a pipe body 46 and a faucet part 40 (for recovering the concentrated water). The second pump sucks the concentrated water into the RO module 2 by the actuation of a valve body 44 associated with the rotation of the pump shaft 27, the sucked concentrated water is discharged from a concentrated water drain passage 43 to a faucet part 42 (for discharging the concentrated water), and the discharged concentrated water is discharged from a drain hose 51.
