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.

The problem addressed by the present invention is to suitably generate or update an algorithm for a water treatment system. In a filter management serverfor managing a water circulation management system W for treating wastewater using one or more filters, an acquisition unitacquires information necessary for analyzing filterperformance or sample water DW. An analytical unitanalyzes the one or more filterson the basis of the information acquired by the acquisition unit. An analysis results analytical unitanalyzes the one or more filtersor sample water DW on the basis of the results of the analysis by the analytical unit. An update unitupdates the algorithm for water treatment on the basis of the results of the analysis by the analysis results analytical unit. This configuration solves the aforementioned problem.

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. The water treatment system containing shower stalls which, when input water is used by a user, output the used water as drain water, wherein treated water sensors 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 and the drain water output from each of the shower stalls. An information generation unit generates information pertaining to the use by a user of each of the shower stalls based on at least a portion of the results from the treated water sensors.
