Dissolved Oxygen Measurement
11/11/2013
One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

Immediate pH Correction For Fluctuating Flow
2/19/2014
In a number of water, wastewater and industrial process applications, pH is one of the most critical and highly sensitive analytical measurements. Examples of critical pH applications include: Reverse Osmosis (RO) systems in which a controlled feed of caustic solution is typically added to the feed stream in order to convert a portion of dissolved carbon dioxide into bicarbonate precipitate allowing for removal by the RO membrane.

Secret To Disinfection Monitoring For High Chlorine Residual Wastewater Applications
8/2/2015
Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.

Recording & Control: In Coagulant Dosage Applications For Potable Water Treatment
7/1/2019
Potable water or drinking water as it is also known, is water that is safe to drink or to be used in food preparation. Typically, in developed countries, tap water meets the required drinking water standards although only a small proportion is actually drunk or used in food preparation. Coagulant is added to potable water as part of the treatment to create suspended solids that are large enough to be removed through the process of sedimentation.

How To Read An Encoder
9/13/2013
The HR-E LCD encoder has a 9-digit Liquid Crystal Display (LCD) to show consumption, flow and alarm information. The display automatically toggles between 9-digit and 6-digit consumption, rate of flow and meter model.

Application Note: Water Flows From The Golden Hills Of California
1/20/2010
Each morning John Johnson drives the few miles from his smalltown home in northern California to the Center at Pardee Reservoir. Nestled among the foothills of the Sierra Nevada mountain range, the reservoir is a long 100 miles away from San Francisco Bay. By YSI

Improved Efficiencies In TOC Wastewater Analysis For Standard Method 5310B And EPA Method 415
10/16/2014
Total organic carbon (TOC) measurement is of vital importance to the operation of water treatment due to organic compounds comprising a large group of water pollutants. TOC has been around for many years, and although it is a relatively simple analysis in theory, operational efficiency is paramount.

Background And Summary Of Tests For The 2000PV Restraint
4/13/2021
The 2000PV is a restraint for PVC pipe and the standardized mechanical joint. This product is the result of years of testing and evaluation and its performance has been proven by thousands of hours of proof tests, as well as third-party evaluations. This report describes the 2000PV through the 12" size.
