  • The Measurement of Turbidity and Suspended Solids
    We say that a particular water sample is turbid when the sample is hazy or cloudy. The main effect of the haziness is that we cannot see clearly through the sample after a certain distance, as the distance over which it is possible to see clearly decreases as the turbidity increases.
  • Is Your Cooling Tower Water Filter Missing 85% of Suspended Solids?
    An effective cooling tower water filtration system removes suspended particles to reduce turbidity and prevent scaling and corrosion in your equipment. But not all filters are created equal. Most filters capture only the largest solids, making the cooling water appear clear but actually leaving

    before & after flocculation/softening. * Acceptable levels dependent upon alkalinity. * Turbidity analysis to meet new filtration requirements. * SUVA alternate compliance test. Compliance Deadlines: * Large Surface Water or GWUDI**Systems January 1, 2002. * Small Surface Water or GWUDI**Systems January
  • Water Quality Changes During 500-Year Flood Controlled with Sievers TOC Analyzer
    During the flooding, the Cobb County - Marietta Water. Authority realized the importance of knowing more than. just the turbidity levels in their source water. By identifying. TOC values, the plant was able to optimize their chemical. addition, potentially avoiding excessive chemical costs
  • Development of a Low-Maintenance Turbidimeter
    State-of-the-art turbidity meters for potable water analysis are based on the nephelometric measurement principle as described in Standard Methods and adopted by the ISO standards. Turbidity is determined by the measurement of light, scattered at an angle of 90° to the incident beam.
  • Coagulation and Flocculation
    Water is clarified using the processes of coagulation and flocculation, which remove suspended solids (turbidity) from water by causing the suspended particles to aggregate into a slime, that settles out of the water. This technique is used in treating wastewater, both industrial and treated sewage
  • Organics Aren't Invisible: A Guide for Simple Online Monitoring
    counter-terrorism or water security. Despite the critical need, many plants still rely primarily on turbidity for monitoring and process control. Today, UV-based technologies are making continuous online organics monitoring simple, accurate, and affordable for many plants. In this article, we'll discuss
  • Tech Tip 7 - Epoxy Crystallization
    It can often come as a surprise, but crystallization is more of an inconvenience rather. than a problem. The ones who are most aware of it are our customers. Frequently, a jar, bottle, bucket or container looks cloudy, turbid or even solid upon inspection. By definition, it is referred
