    Abstract: The invention relates to a computer-implemented method, computer program, and device for evaluating timed-based probabilities of failure of sections of a pipe network. To do so, the pipe sections are clustered into classes based on structural and environmental parameters; within each class a sample of pipe sections are selected to be inspected. The scores that are obtained through the inspection are used to train a model of pipe conditions of pipes in a class, in order to estimate the pipe conditions of pipes that have not been inspected. The pipe conditions are used to parameterize a predictive model of pipe failures.

    Abstract: Disclosed is a wastewater treatment system and method for an advanced treatment of refractory organic matters in wastewater. The wastewater treatment system comprises an ozone treatment device (1) and a biological filter (2). An ozone dosing device (3) of the ozone treatment device (1) prepares ozone by electric discharge using air or pure oxygen as a raw material. A mixed gas including ozone and excess air or oxygen discharged therefrom is introduced into an ozone-oxygen contact tank (7) such that the wastewater to be treated is subjected to ozone oxidation treatment and oxygen absorption, and an effluent is introduced into the biological filter (2), so that the biological filter (2) does not need to provide an aeration device to increase oxygenation for microorganisms. The wastewater treatment system and method fully utilize the supersaturated dissolved oxygen in the effluent of the ozone treatment device (1) to replace the aeration system of the subsequent biological filter (2), and have the advantages of high mass transfer efficiency, high biological activity, high volume load, high removal rate, and the like. The filter (2) has a simple structure and high backwashing efficiency, which significantly reduces operating costs. For the removal of refractory COD, the economics of the overall process are greatly improved.

    Abstract: An apparatus for generating and storing in a tank (22) a flowable slush (2) of frozen particles usable inter alia in ice pigging comprises a control system (100) which is arranged to monitor an operating parameter OP of an agitator (23) in the storage tank. The control system initiates a slush comminution and separation or dewatering cycle when a control parameter CP based on the operating parameter OP reaches a threshold value CPt. The control parameter may represent a cumulative energy input to the storage tank (22). Comminution may be performed prior to separation, with the treatment cycle being terminated when a sensed rheometric parameter RP of the slush circulating in the treatment flowpath reaches a target value RPt.

    Abstract: La présente invention porte sur une zone humide artificielle pour l'élimination d'un ou plusieurs polluants d'un effluent comportant au moins deux compartiments, dans laquelle les dimensions des compartiments permettent de favoriser différentes réactions. La synergie des réactions se produisant dans les différents compartiments permet d'améliorer la capacité épuratoire d'une zone humide artificielle selon l'invention par rapport à une zone humide artificielle de l'état de l'art. Les dimensions des zones humides selon l'invention permettent également d'atteindre un taux cible d'élimination de polluants de l'effluent, avec une emprise au sol aussi petites que possible. La présente invention porte également sur une méthode de définition d'une telle zone humide artificielle.
