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: A reverse osmosis system and method includes a pump pressurizing a feed stream, a first and second membrane array that generates permeate and brine streams. A first energy recovery device uses first energy from the second brine stream to pressurize the first brine stream. A first and second auxiliary and bypass valves are associated with the first and second energy recovery device. A second energy recovery device uses second energy from the second brine stream to increase a second pressure of the feed stream. A first flowmeter generates a first flow signal for the first permeate stream. A second flowmeter generates a second flow signal for of the second permeate stream. A third flowmeter generates a third flow signal for the second brine stream. A motor drives the first energy recovery device. A controller controls the in response to the flow signals.
