Systems and methods for testing biocide

A method for testing one or more biocides, comprising:

• controlling a first three-way control valve to fluidly couple a source of water to a first test conduit of a first test column of a biocide testing system;
• circulating a flow of the water into a first inner volume of the first test conduit;
• immersing a first plurality of test coupons positioned in the first inner volume in at least a portion of the flow of water;
• fluidly coupling the first test conduit with a second test conduit of a second test column of the biocide testing system by opening a second three-way control valve coupled to a first loop conduit that is coupled between the first test conduit and the second test conduit;
• circulating the flow of the water into a second inner volume of the second test conduit;
• immersing a second plurality of test coupons positioned in the second inner volume in at least another portion of the flow of water;
• controlling the second three-way control valve to fluidly isolate the first test column from the second test column;
• after a first time duration:
• fluidly coupling a source of a first biocide to the first test conduit by opening the first three-way control valve,
• circulating a flow of the first biocide into the first inner volume of the first test conduit,
• immersing the first plurality of test coupons positioned in the first inner volume in at least a portion of the first biocide, and
• determining an effectiveness of the first biocide based on the immersion of the first plurality of test coupons in the portion of the first biocide;
• and
• after a second time duration:
• fluidly coupling a source of a second biocide to the second test conduit through a bypass conduit by opening the second three-way control valve;
• circulating a flow of the second biocide into the second inner volume of the second test conduit;
• immersing the second plurality of test coupons positioned in the second inner volume in at least a portion of the second biocide;
• and
• determining an effectiveness of the second biocide based on the immersion of the second plurality of test coupons in the portion of the second biocide, wherein a start time of the second time duration is coincident with a start time of the first time duration, and an end time of the second time duration is subsequent in time to an end time of the first time duration.

• circulating the flow of the water into a third inner volume of the third test conduit;
• immersing a third plurality of test coupons positioned in the third inner volume in at least another portion of the flow of water;
• fluidly isolating the first and second test columns from the third test column by closing the third three-way control valve;
• and
• after a third time duration:
• fluidly coupling a source of a third biocide to the third test conduit through the bypass conduit by opening the third three-way control valve,
• circulating a flow of the third biocide into the third inner volume of the third test conduit,
• immersing the third plurality of test coupons positioned in the third inner volume in at least a portion of the third biocide, and
• determining an effectiveness of the third biocide based on the immersion of the third plurality of test coupons in the portion of the third biocide, wherein each start time of the first, second, and third time durations is coincident, and an end time of the third time duration is subsequent in time to an end time of the second time duration, and the end time of the second time duration is subsequent in time to an end time of the first time duration.
