Abstract
A water treatment method including: a concentration step of concentrating microorganisms in sample water to purify a concentrate; a detection step of detecting an inhibitor contained in the sample water or the concentrate; a determination step of determining whether to perform a removal step based on a result of the detection in the detection step; the removal step of removing the inhibitor from the concentrate in a case where the removal step is determined to be performed in the determination step; and a measurement step performed after the determination step or the removal step, of measuring the microorganisms contained in the concentrate.
Claims12
A water treatment method comprising:
- concentrating sample water containing microorganisms to obtain a purified concentrate comprising the microorganisms;
- detecting an inhibitor contained in the sample water or the concentrate to obtain a detection result;
- determining whether remove the inhibitor from the concentrate based on the detection result;
- removing the inhibitor from the concentrate when determined to be performed in the determining;
- and
- measuring the microorganisms contained in the concentrate after the determining or the removing;
- wherein conditions for the removing are determined according to an index value of the inhibitor, said conditions including:
- at least one of a type, number, frequency, sequence, and duration of the removing;
- and/or the amount of reagent to be used in the removing.
A control apparatus comprising:
- a sensor configured to detect an inhibitor contained in sample water containing microorganisms or a concentrate purified by concentrating microorganisms in the sample water;
- and
- a controller configured to determine whether to remove the inhibitor from the concentrate based on a detection result obtained by the sensor;
- wherein, when the controller determines that the inhibitor is to be removed from the concentrate, the controller is configured to control a water treatment process so that the concentrate passes through a removal apparatus that removes the inhibitor from the concentrate prior to measurement of the microorganisms, in a removing, the removal apparatus determining conditions for the removing according to an index value of the inhibitor, said conditions including:
- at least one of a type, number, frequency, sequence, and duration of the removing;
- and/or the amount of reagent to be used in the removing.
