Up against their BOD permit limit, the Rand-Whitney Containerboard mill in Montville, Connecticut was proactively seeking solutions that would enable them to monitor their production processes more closely with the goal to identify sources of high wastewater loading and make…
Reducing product loss and limiting COD discharge to the municipal sewer system were key goals for a dairy manufacturing plant. The facility looked to Real Tech to help achieve these goals, installing an industrial grade, real-time BOD/COD probe on the…
LOST PRODUCT = LOST REVENUE Manufacturers in the food and beverage industry lose significant quantities of product in the production process. In the dairy industry, milk losses are on average 2-3% of total production and can be even higher for…
Water quality monitoring has evolved significantly over the past decade. Today’s industrial manufacturers have access to technologies that are capable of monitoring various wastewater quality parameters and contaminants of concern in a simple and effective manner. A continuous stream of…
Real-time BOD monitoring is becoming increasingly popular, and it’s no surprise as the alternative is a 5 day wait for lab results. Continuous organics monitoring opens the door for many new treatment process control and optimization possibilities that can result…
Wastewater quality can change drastically and quickly – particularly in the case of industrial discharges – to generate shock loads within the wastewater treatment system. In addition to potential operational problems such as increased chemical and aeration demand, shock loading…
A paper recycling facility in Ontario, Canada, needed an effective solution for monitoring carbon content in the wastewater in real time for nutrient dosing optimization and process control purposes. The plant’s existing control strategy was to monitor COD by collecting…
PARAMETERS TO MEASURE FOR NUTRIENT DOSING IN WASTEWATER BOD, COD, TOC, TSS OVERVIEW Nutrient dosing in wastewater must be carefully controlled to ensure a favorable nutrient ratio is achieved, resulting in good quality effluent. Real-time online monitoring of organic loading…
PARAMETERS TO MEASURE FOR AERATION OPTIMIZATION BOD, COD, TSS, DO OVERVIEW A significant portion of a wastewater treatment plant’s energy costs are due to aeration operations (~45-75% of the total energy). The required aeration rate of a biological treatment system…
SPECTROPHOTOMETRY OVERVIEW Spectrophotometry is a well-established analytical method, which has been used for decades in chemistry, physics, biochemistry, and chemical engineering for quantitative analyses. A light source and sensor are used to measure the intensity of light passing through a water sample…
