Abstract: The present invention provides a use of an inorganic salt or acid capable of producing free phosphate or fluoride ion in reducing the hardness and/or alkalinity of a water system containing residual antiscalant. In the lab test, it is found that the addition of a suitable amount of sodium phosphate or sodium fluoride may induce alkalinity reduction as well as hardness reduction. The production efficiency can be enhanced since the scaling was relieved and heat exchange efficiency can be improved. Meanwhile, lower scaling stress also means lower antiscalant dosage and cost, and thus the total operation cost can be reduced.

Abstract: Embodiments include a beam determining unit intended to be connected to a wireless heterogeneous network and a beam-searching method for a wireless heterogeneous network. In the context of a millimeter wave heterogeneous network, it is proposed to do away with the conventional exhaustive beam-searching procedure which is both time and power consuming. Instead, it is proposed a two-step procedure where a line of sight path is determined between a user equipment and a small cell of the millimeter wave heterogeneous network based on positioning information of the user equipment and the small cell. Then, it is determined an optimal antenna beam pair comprising antenna beams at the user equipment and the small cell based on the determined line of sight path and the antenna beam directions available at the user equipment and the small cell level.
