WASTEWATER ANALYSIS WHITE PAPERS & CASE STUDIES
Hach’s off‐the‐shelf Real-Time Control System for Sludge Thickening (RTC‐ST) adjusts the sludge thickening process in real time. Thanks to the RTC-ST, a wastewater treatment plant improved thickened sludge consistency and gas production while reducing money spent on excessive polymer dosing and maintenance.
Rumors, Half-Truths, And Truths About Temperature And pH
A few months ago I received a call from an angry user who was using one of our differential probes and a controller. Embedded in the probe is a thermistor that measures temperature.
How Automated Real-Time Controls Can Provide More Consistency In Wastewater Treatment Operations
Within a wastewater treatment plant (WWTP), operators typically face an extremely wide range of different variabilities.
Coal Yard Runoff Compliance Using Actiflo® Technology
Storm water runoff from a 37-acre coal storage yard utilized as part of daily operations at an industrial site in Southwestern Pennsylvania posed a problem when the Pennsylvania Department of Environmental Protection (DEP) updated the facility’s NPDES permit.
Measure And Control Cyanide With The CNSolution 9310
The CNSolution 9310 analyzer is used in precious metal processing to measure and control cyanide used in the hydrometallurgical leaching of gold and silver from the ore.
Color, Turbidity And Philosophy
When we humans look at objects we describe them in terms of color. We say that an apple is red or a leaf is green. To us color is an attribute just as surely as the mass or dimensions of an object. But the fact is that color is a pure human construct. Take away the human and it does not exist.
Pilot Testing Potassium Sulfate Crystallization
ICP’s Ochoa Mine Project is projected to produce approximately 714,000 tons per year of SOP (K2SO4) from polyhalite ore for greater than fifty years as concluded in a feasibility study.
Calculated pH By Differential Conductivity Measurement In Mixtures Of Alkalizing Agents
Proper measurement of pH is a key factor of corrosion risk surveillance in water-steam cycles.
Case Study Of Swan Turbiwell Quarterly Calibrated Unit Versus Quarterly Verified Unit
This paper presents the field data collected over a twelve month period at a municipal surface water treatment plant employing traditional clarification and filtration. The final effluent turbidity was monitored by the third party compliance turbidimeter, a Swan Turbiwell (Protocol Turbiwell) was calibrated quarterly just as the compliance turbidimeter, and a second Swan Turbiwell (Non-protocol Turbiwell) that was not calibrated.

Smart Wireless Technology Solves Environmental Monitoring Challenge
Faced with the challenge of meeting environmental monitoring legislation, Korsnäs Gävle needed a way to monitor water from their heat exchangers for contamination before discharging it to the sea. Additionally, the board and paper manufacturer required new sensors for continuous monitoring of pH, dissolved oxygen, and water temperatures from effluent emissions in their basins and ponds. In this case study, learn how Korsnäs Gävle implemented a wireless sensor network to quickly achieve compliance and meet its monitoring needs.
How To Control Activated Sludge With Online Sensors
The goal for domestic wastewater treatment in the 21st century should be to have a minimal carbon footprint and to be 100% self-sustainable with regards to energy, carbon, and nutrients – while achieving a discharge or reuse quality that preserves the quality of receiving waters (Water Environment Research Foundation (WERF), 2009). Sustainability with respect to energy requires both conservation and production. By Dr. Robert Smith, Ph.D., P.E., BCEE, YSI, a Xylem brand
