Abstract: The problem addressed by the present invention is to suitably generate or update an algorithm for a water treatment system. In a filter management server 1 for managing a water circulation management system W for treating wastewater using one or more filters 31, an acquisition unit 101 acquires information necessary for analyzing filter 31 performance or sample water DW. An analytical unit 102 analyzes the one or more filters 31 on the basis of the information acquired by the acquisition unit 101. An analysis results analytical unit 104 analyzes the one or more filters 31 or sample water DW on the basis of the results of the analysis by the analytical unit 102. An update unit 105 updates the algorithm for water treatment on the basis of the results of the analysis by the analysis results analytical unit 104. This configuration solves the aforementioned problem.

Abstract: A water treatment apparatus management system which manages a household water treatment apparatus located at or near a place of water use, and treats water before treatment with at least one type of filter to produce treated water for the place of water use. The system includes: a filter information storage unit storing information regarding an in-service filter used in the household water treatment apparatus; an information receiver receiving information regarding performance change of the in-service filter from the household water treatment apparatus; and a water type estimation means that estimates a water type of the water before treatment based on the information regarding performance change and the information regarding the in-service filter. The information regarding the in-service filter includes reference information of performance change of the same or the same type of filter as the in-service filter for each of plural types of reference water before treatment.

Abstract: Appropriately generate or update algorithms for a water circulation management system. In a filter management server having a processor for managing the water circulation management system equipped with various sensors including a treated water sensor and a drainage water sensor, for treating drainage water using one or more filters, the processor acquires, using the various sensors, predetermined information necessary for analysis of each of performance of the filters and status of use by a user of a water utilization unit. The processor generates, by analyzing the predetermined information and based on information from the various sensors, information related to timing of replacement of the one or more filters, and user use information including use status of a water utilization unit by the user and water use information including water pollution degree. The processor executes control to notify the user of the water use information and the user use information.

Abstract: The present invention addresses the problem of providing a water treatment system with which it is possible to efficiently share a plurality of water utilization means including a shower, and with which it is possible to use drain water in environments in which it is difficult to secure water. Provided is a water treatment system containing shower stalls 5-1 to 5-4 which, when input water is used by a user, output the used water as drain water, wherein treated water sensors 4C-1 to 4C-4 are capable of detecting a given physical amount, or an amount based thereon, pertaining to at least a portion among the water input to each information processing device controlling the shower stalls 5-1 to 5-4 and the drain water output from each of the shower stalls 5-1 to 5-4. An information generation unit 102 generates information pertaining to the use by a user U of each of the shower stalls 5-1 to 5-4 on the basis of at least a portion of the results from the treated water sensors 4C-1 to 4C-4. This thus solves the abovementioned problem.
