Abstract: The invention relates to a method for cleaning a sensor in a wastewater monitoring arrangement comprising at least one sensor with a sensor surface, such as an optical sensor with a window, lens, or the like. In the monitoring arrangement, during a normal operation mode, a sample flow of wastewater is arranged to flow past the sensor surface and the sensor is arranged to provide measurement values that describe a quality parameter of the wastewater. The method comprising steps of: starting a sensor cleaning cycle by discontinuing the sample flow; starting a cleaning liquid flow; arranging the cleaning liquid flow towards the sensor surface; mechanically cleaning the sensor surface by an automatic cleaning device; discontinuing the cleaning liquid flow after a predetermined cleaning time and ending the cleaning cycle; and starting the wastewater flow again.

Abstract: A method of controlling addition rate of an odor control chemical to a wastewater line by adding odor control chemical to the wastewater. The method includes measuring a level of dissolved sulfides in the wastewater line using a sulfide probe placed in said wastewater line, transferring data on the level of dissolved sulfides to a computing unit, determining a required odor control chemical addition rate in said computing unit based on said level of dissolved sulfides, and adding the odor control chemical at said required addition rate. The method allows for accurate on-line control of the level of H2S in the wastewater line.

Abstract: The invention describes a method and system for controlling the addition rate of a contaminant control chemical to a water or wastewater line. The level of hexavalent chromium as a contaminant in the water or wastewater is measured using a spectro-photometric probe placed in the line. Data representative of the level of measured hexavalent chromium content is read into a computing unit, which determines a required contaminant control chemical addition rate based on said level of hexavalent chromium content. The contaminant control chemical is then added at the required addition rate to reduce the amount of hexavalent chromium to a predetermined level.

Abstract: According to various embodiments of the present invention, systems and methods for local number portability in a telecommunication network are disclosed. An embodiment of a method includes submitting a local number portability (LNP) order for the TN directly to a first telecommunications carrier that the TN is to be transferred from, triggering a port of the TN in accordance with the LNP order, and porting the TN from the first telecommunications carrier to the second telecommunications carrier, wherein the second telecommunications carrier is bypassed by the customer during the submitting and the triggering of the LNP order. Other embodiments are also disclosed.

Abstract: According to various embodiments of the present invention, systems and methods for local number portability in a telecommunication network are disclosed. An embodiment of a method includes requesting a real-time (RT) customer service record (CSR) request for a telephone number (TN) associated with a local number portability (LNP) order, the requesting occurring prior to a second CSR request that occurs as part of a submit process for the LNP order; receiving, in response to the request for the RT CSR request, a RT CSR response from a telecommunications carrier that the TN is to be transferred from as part of the LNP order; and validating data in the RT CSR response in order to prevent rejections of the data in the second CSR during the LNP process. Other embodiments are also disclosed.

Abstract: According to various embodiments of the present invention, systems and methods for local number portability in a telecommunication network are disclosed. An embodiment of a method includes receiving a telephone number (TN) to test for its porting activity as part of a local number portability (LNP) order, accessing a LNP call tester (LCT) to determine a current local routing number (LRN) for the TN, and determining, based on the TN and current LRN, whether the porting activity is completed for the TN in relation to a core telecommunications carrier servicing an owner of the TN. The porting activity may include at least one of port in, port out, and migration of the TN. In one embodiment, the planned porting activity for the TN associated with the LNP order is known prior to determining whether the porting activity has been completed. Other embodiments are also disclosed.
