Particle Analysis Instruments in Water Treatment

The purification of drinking water is a multi-step process that typically requires cleaning with a biochemical or catalytic agent and filtration through a solid phase media. This process is doubly complicated by the varying requirements of different water sources. Groundwater may contain significant volumes of suspended particulates such as salt or geological sediment, while water drawn from underground sources may comprise high levels of harmful minerals such as arsenic or manganese. Particle analysis instruments are used for quality control and process monitoring in water treatment applications. This method provides quantitative detection of microorganisms or suspended solids in a sample, to qualify the purity of filtrate water. It can also be used to assess the demands of a new feed and to monitor the long-term performance of filtering components. This blog post will explore some of the leading particle analysis instruments for water treatment processes in more detail. FlowCam The FlowCam range provides a direct image-based assessment of particle size and morphology across an overall range of 0.3 ? 5,000 micrometers (?m). It can accurately count and measure the concentration of particles in a heterogeneous solution, with advanced particle morphology characterizations enabling identification of particles such as different algal species. This innovative particle analysis instrument can apply over 40 different morphological measurements to individual particles with a high measuring throughput of up to 1 liter per minute (L/m). The FlowCam is preferable for measuring particles and detecting the presence of cleaning or catalytic agents that have propagated through the filtration process. Multisizer 4e The Multisizer 4e is a robust particle analysis instrument that is used for characterization of marine particle species and suspended solids in water. It operates on a novel arrangement of the Coulter Principle and Digital Pulse Processing (DPP) for ultra-high-resolution particle counting and characterization. This particle analysis instrument boasts an overall sizing range of 0.2 ? 1,600 ?m for volumetric quantitation of organic or inorganic particles in feed water. It can provide rapid assessment of the microorganisms and total suspended solids in a sample to characterize the feed and inform water filtration best practice, with built-in filtration efficiency calculations in the software. The Multisizer 4e can also be used for quality control of filtrates to ensure drinking water is safe for human consumption. nCS1 The nCS1 operates using a unique technology known as microfluidic resistive pulse sensing (MRPS) to size subvisible particles in solution. It can precisely measure nanoparticles of any physiochemical composition across a range of 40 ? 2,000 nanometers (nm). This particle analysis instrument is preferable for quality assessment of feed waters with severe filtration requirements. Nanoscale organisms and harmful particulates may be resistant to cleaning agents small enough to pass through the porous structures of a filtrate component. The nCS1 provides quantitative analysis of nanoscale particle species in drinking water to ensure unerring water treatment efficiency.
