Wastewater from dairy applications has high amounts of calcium and phosphorus. This characteristic may cause scaling on the media of a Moving Bed Biofilm Reactor and may cause poor COD removal. Veolia was able to retrofit the client’s existing MBBR with the newly designed Z-MBBR media by AnoxKaldnes, which improved the operation of the entire wastewater system.
A Netherlands power station installed 3M Liqui-Cel membrane contractors for O2 removal. This case study explains how the membrane system exceeded expectations, achieving oxygen removal down to 5 ppb.
Controlling dissolved oxygen (DO) levels during beverage production is vital for ensuring consistent product quality and shelf life. This is particularly true for canning, where high DO levels can cause breakdown of the can lining, corrosion and even leaking – which in turn can result in product waste and customer dissatisfaction. In some cases, can supplier warranties have exclusions for high DO levels.
Dissolved gases like NH3, H2S or NOx in waste water lead to contamination in the sewage system and high treatment costs for municipal waste water treatment plants.
Too much of a good thing can create new problems as quickly as it resolves old ones. Maintaining a proper balance of antifoaming agents and polymer additives is critical for sustaining the appropriate air bubble size and distribution needed to achieve dissolved oxygen (DO) requirements for neutralizing high biochemical oxygen demand (BOD) in many industrial and food processing wastewater applications.
The city of Buhl, Idaho, obtains all of its drinking water from groundwater sources through multiple wells. Prior to 2009, the city did not treat the groundwater but only added chlorine in the form of bulk 12.5% sodium hypochlorite to provide a disinfectant residual. A combination of factors including: changes in EPA and state DEQ regulatory requirements, growth of the residential population and growth of the industrial food processing customers forced the City to build a new water treatment plant to provide filtration to address the naturally occurring arsenic present in the groundwater.
In the food and beverage industry, there is a growing awareness of environmental considerations wherever chemicals are used. In response, companies are trending towards alternative systems that operate with less chemical usage.
