An automatic measurement system for Sludge settling Velocity comprises a sampling and shooting module, a data service module, a data processing module, and a measurement and analysis module. The sampling and shooting module is configured to collect samples and to obtain test images of samples. The data processing module is configured to collect and store process data. The measurement and analysis module is configured to obtain the sedimentation ratios of samples according to test images. The sludge activity is analyzed according to the sedimentation ratios. When the sludge activity is abnormal, the process data are obtained from data processing module, and the process analysis data are obtained according to the data and the sludge activity analysis results. The automatic measurement system can avoid errors caused by manual measurement and improve accuracy and efficiency of detection and can avoid the problems of untimely detection.

Various embodiments disclose an electronic circuit for an electrochemical gas sensor. The electronic circuit comprises a first switching element electrically coupled to a reference terminal of the electrochemical gas sensor and a ground voltage terminal. Further, the electronic circuit comprises a second switching element electrically coupled to a sensing terminal of the electrochemical gas sensor and the ground voltage terminal. In an instance in which the electrochemical gas sensor is powered OFF, the first switching element and the second switching element are configured to electrically couple the reference terminal and the sensing terminal to the ground voltage terminal such that current generated when the sensing electrode and the target gas react while the electrochemical gas sensor is powered OFF flows to the ground voltage terminal and the potential of the reference terminal and the sensing terminal remain the equal.

The present invention relates to a release aid that includes at least one succinic anhydride derivative for use in a papermaking process. For example, the release aid of the present invention is particularly useful for use in a paperweb creping process. The present invention also relates to a paperweb creping method that includes a release aid comprising at least one succinic anhydride.

Release aid

The present invention relates to colloidal silicas having a low S-value and a high solids content, the preparation thereof, and the use thereof in the production of paper. When used in the production of paper, the colloidal silicas of the invention exhibit good retention and drainage performance so that they can be used in lower amounts compared to conventional colloidal silicas. The present invention also relates to an apparatus and a method for producing such activated colloidal silicas.
