摘要： A water float is formed by fixedly sandwiching a plurality of foamed resin members spaced apart from each other in a plane, with a pair of surface sheets of thermoplastic resin. The thus-formed water float of a large area may suitably be floated on water surfaces of lakes or ponds, pools, dams, rivers and seas, for preventing deterioration of water qualities due to occurrence of mosses, such as water-bloom; or as bases for installing thereon view facilities such as illuminations, advertisement media and solar batteries. A plurality of the water floats may be disposed in a plane and connected with each other so as to form a water float connection system of a larger area.

摘要： A method of producing an aqueous solution of slaked lime is disclosed the steps of which includes introducing water into a slaked lime-dissolving apparatus comprising a dissolving tank (1), a water supply piping (2) connected to a lower part of the tank, a stirring blade (3) disposed within the tank in its bottom part, an effluent piping (6) connected to an upper part of the tank for discharging aqueous slaked lime solution, and a fluidized slaked lime layer height-control device (5) disposed within the tank above the stirring blade, subsequently introducing a predetermined amount of slaked lime into the tank, feeding water, with low-speed stirring, to the tank from the water supply piping in such a rate that the water in the cylindrical or rectangular upper part of the tank ascends at a rate of from 0.25 to 1.2 mm/sec, and taking out an aqueous solution of slaked lime from the tank through the effluent piping.

摘要： A method is disclosed for reducing the corrosiveness of a water supply, and preventing the generation of red water caused by iron rust, by modifying the Langelier index of the water, which comprises:
(1) determining the amount of carbon dioxide required to increase the concentration of free carbonic acid in the water based on the existing and desired Langelier indices, and the acceptable pH range, of the water supply;
(2) dissolving the said amount of carbon dioxide gas in the water to generate free carbonic acid in the water; and
(3) adding a substantially saturated aqueous solution of slaked lime to the water supply such that the free carbonic acid is neutralised and the desired Langelier index is achieved.
An apparatus for carrying out the method is also disclosed.摘要翻译： 公开了通过改变水的Langelier指数来降低供水的腐蚀性并防止由铁锈引起的红水的产生的方法，其包括：（1）确定增加所需的二氧化碳的量 基于现有和期望的Langelier指数和供水的可接受的pH范围，游离碳酸在水中的浓度; （2）将所述量的二氧化碳气体溶解在水中以在水中产生游离碳酸; 和（3）将大部分饱和的熟石灰水溶液加入到水源中，使游离碳酸中和，达到所需的Langelier指数。 还公开了一种用于执行该方法的装置。
