In critical water analysis and water quality monitoring environments, the ability to rapidly detect, identify, and quantify nuisance taste and odor algae or problem particulate matter in real-time is essential to providing high levels of customer satisfaction.
FlowCAM accelerates sample processing to just a few minutes - allowing you to quickly monitor algae and particulates throughout your process and make it more efficient.
A good floc formation is important for drinking water plants, because it is the mechanism used to collect and transport all filterable pollutants, including Cryptosporidium, Giardia, bacteria, viruses, arsenic, total organic carbon (TOC), and disinfection byproduct (DBP) from the water supply.
The FlowCam allows you to control pollutant-floc formation through coagulant chemical dosing and floc-motor speed, measure and track floc formation in flocculation and sedimentation basins, and review the rapid success-failure feedback of dosing and mixing changes long before filter turbidity or particle counts have an opportunity to spike. Additionally, you can achieve a clear advantage in process optimization and control by tracking and trending the floc and suspended solids imaging, count and size data over time.
You can also use the FlowCam to capture detailed images of floc particles. With FlowCam’s VisualSpreadsheet® software, you can perform complex object analysis on floc particles with unparalleled accuracy and speed. FlowCam also measures such as floc diameter, volume, volume concentration, and counts in near-real-time, data can be analyzed in either numerical or graphical formats.
Filter issues can affect plant performance and increase cost of plant operation. Most algal species are rejected by filters because they are larger than the pore size of typical water plant filters. Filter fouling can occur as a result of accumulation and adsorption of rejected materials at the media surface. In the presence of algae, the layer of rejected material at the media can be “cement-like” for the particulate material rejected by the filter surface. This algal slime contributes to a greater resistance to filtration, reduced filter runs, and the need for frequent backwash cycles.
The algae monitoring capabilities of the FlowCam accelerates sample processing to just a few minutes. With faster and more accurate detection, confident assessment of a growing presence of nuisance algae is achieved so that remedial action may be taken before the algae bloom becomes problematic in the filter system.
Water treatment plant performance is evaluated by methods such as turbidity, particle counting, and microscopic particulate analysis (MPA). While MPA combined with particle counting provides critical information about the type and number of organisms and particles present, it is a very time consuming process.
The FlowCam accelerates sample processing to just a few minutes, and combines the imaging aspect of MPA with the particle distribution and concentration information of particle counting. The analysis compares the type, size, and quantities of bioindicators and particles found in the raw water to those found in the treated water. These methods provide a unique view and can be used to evaluate filtration efficiencies (or log removal) in conventional and membrane filtration systems.
