摘要： PROBLEM TO BE SOLVED: To provide a pipe cleaning apparatus which can clean reciprocatingly effectively in piping, and a cleaning method of the piping which can clean reciprocatingly effectively in the piping using the pipe cleaning apparatus. SOLUTION: The pipe cleaning apparatus 1 comprises a cleaning part 3 which contacts to the inner wall 2a of the piping 2 and removes fouling from the inner wall 2a of the piping 2 by the movement of the whole pipe cleaning apparatus 1 in the piping 2. The cleaning part floats on a fluid 6 flowing in the piping 2, and at the same time moves (rises and lowers) in the piping 2 accompanying the movement (rising and lowering) of the fluid 6.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus and method for preventing the oxidation of groundwater which can avoid a risk of trouble generation, such as deterioration of pumping efficiency and clogging, due to adhesion of iron oxide, generated in groundwater before being pumped up, to a storage pump in a well, piping for pumping water and the like.
SOLUTION: The apparatus 1 for preventing the oxidation of groundwater is provided with a wood 40 as organic matter, which is disposed in the groundwater 20 in the well 10 and contains vegetable fiber. The wood 40 has a reducing power of changing the oxidation reduction potential of the groundwater 20 in the well 10 to a minus side.
