Abstract: An integrated boron removal and flocculation process for treating fracturing wastewater is disclosed. The process comprises: adjusting the pH of the fracturing flowback liquid to be treated to become alkaline and adding thereto an oxidant to carry out a reaction for a certain time period, so that the state of the boron present in the liquid is changed; and then adding a barium salt to the resulting reaction mixture to carry out a further reaction between the barium salt and the boron in the changed state to produce a precipitate. The stability of the flowback liquid is deteriorated by the addition of the oxidant.

Abstract: Automated processes, computing systems, devices and other aspects of a wireless data network are described. According to various embodiments, message flooding in the wireless network is reduced through the use of “dummy” messages from the radio unit (RU) to the distributed unit (DU) and/or layer two (L2) switch. The dummy messages prevent timeout of the RU's data in the L2 switch's routing tables, thereby prolonging the period of time that the L2 switch is able to more efficiently direct subsequent traffic toward that particular device.
