A Strategy For Optimizing Water Treatment Plant Performance Using Light Scatter Technologies
Two new particle detecting technologies have been developed to help optimize filter performance at water treatment plants (WTP).
Hach FilterTrak 660™ Sc Laser Nephelometer Even More Practical For Ultra-Low Turbidity Monitoring
Now compatible with the Hach sc100 Controller, the FilterTrak 660 sc Nephelometer connects as a ‘plug and play’ sensor with the universal, dualchannel controller that features an inherent power supply.
Degassing Boiler Feed Water in China with 3M™ Liqui-Cel™ Membrane Contactors
ShenLan Environment Inc. located in Shanghai, China uses 3M™ Liqui-Cel™ Membrane Contactors in their boiler feed water treatment systems. These systems realize lower operating costs with the added benefit of reducing the chemicals added to the boiler feed water.
Application Note: Continuous Monitoring Of Drinking Water Provides Assurance Of Safety
A water utility in Ohio wanted to learn more about the variability of water quality parameters such as pH, ORP, turbidity, and chlorine. Previously, most of these parameters had been measured by spot sampling protocols with only a few
measurements during a daily period. In order to more accurately assess the water variability, the utility used a YSI 6920DW Drinking Water Multiprobe
Operations And LRV Calculations At Southwest Pipeline Project Drinking Water Treatment Facility
This presentation will discuss the operation of a 4 MGD pressurized two-stage Ultrafiltration (UF) plant over a 14 month period at the Oliver-Mercer-North Dunn (OMND) Drinking Water Treatment Facility, North Dakota.
A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Raw And Finished Drinking Water
Total organic carbon (TOC) analysis is an important indicator of water quality throughout the drinking water treatment process. Raw source water is progressively treated in chemical coagulation, flocculation, sedimentation, and filtration steps to remove particulate matter and natural organic matter (NOM).
Application Bulletin: Reverse Osmosis
Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached
Application Note: Desalination Plants: YSI Instruments Monitor Flow & Water Quality At Multiple Stages
Desalination is the process of removing salt from sea water or brackish river or groundwater to make potable water. By YSI
Advances In Paper-Based Devices For Water Quality Analysis
Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.
Application Note: YSI 600 Optical Monitoring System Used To Protect Lake Oconee, Georgia Water Quality
Northern Georgia is experiencing unprecedented development; consequently, water quality in many of its watersheds is in jeopardy of severe degradation. The State of Georgia, Environmental Protection Division (EPD) has implemented
an NPDES monitoring and enforcement program designed to prevent construction activities from impacting water quality
