1. A system for isolating and analyzing a plurality of water and coagulant chemical samples in a water processing facility, the system comprising:
an isolatable chamber for receiving the water and coagulant samples wherein the isolatable chamber further comprises a closable outlet valve located at the bottom of the chamber and an inlet located in a region proximate to the top of the chamber wherein:
the inlet is configured to receive a first sample comprising water and a first quantity of a coagulant chemical at a first time period;the system comprises the first sample;the closeable outlet valve and the inlet are configured to isolate the first sample in the chamber from the rest of the water processing facility at a second time period, whereby the first sample in the chamber can become sufficiently quiescent to allow gravitational settling of suspended particles in the first sample in the chamber;the closable outlet valve is configured to release the first sample at a third time period;the inlet is configured to receive a second sample comprising water and a second quantity of the coagulant chemical at a fourth time period, wherein the second quantity is different from the first quantity;the system comprises the second sample; andthe outlet valve and the inlet are configured to isolate the second sample from the rest of the water processing facility at a fifth time period; an optical detector configured to view and characterize the sizes of a plurality of suspended particles:
in a region of the first sample in the chamber at the second time period; andin a region of the second sample in the chamber at the fifth time period,wherein the first sample region and the second sample region protrude into the chamber; a controller comprising a processor and software wherein the controller is configured to:
send signals that open and close the outlet valve;receive particle size information from the optical detector, wherein the particle size information comprises:
the characterized suspended particle sizes in the first sample at a first time point, wherein the first time point is during the second time period;the characterized suspended particle sizes in the first sample at a second time point, wherein the second time point is during the second time period;the characterized suspended particle sizes in the second sample at a third time point, wherein the third time point is during the fifth time period; andcharacterized suspended particle sizes in the second sample at a fourth time point, wherein the fourth time point is during the fifth time period;wherein:
the first time period, the second time period, the third time period, the fourth time period, and the fifth time period occur sequentially; andthe first time point, the second time point, the third time point, and the fourth time point occur sequentially; andproduce a report showing suspended particle size as a function of time and coagulant chemical quantity; whereby coagulant dosing is adjusted according to the report. |
