Investigating the Effectiveness of Antibiotic Combinations Utilized in Fuel Ethanol Production

Bacterial infections during fuel ethanol fermentations can negatively impact the fermentation process and lower ethanol yields. Lactic acid producing bacteria (LAB), such as Lactobacillus , Lactococcus , Weissella and Pediococcus , are a common source of contamination due to their ability to grow in the harsh conditions, low pH, high temperatures, and high concentrations of ethanol, present during fermentation. [...]

An Introduction to Brewery Wastewater Treatment

Wastewater treatment can be overwhelming, and brewery wastewater treatment is no exception. Regulations and permits often require breweries to treat residual wastewater leftover from the brewing process, and failure to treat this water can result in fines and penalties and the effluent from your facility may negatively impact your community. Wastewater treatment comes in various forms, from primary treatment [...]

Four Commonly Asked Questions in Brewery Wastewater Treatment

Can you recommend a product or treatment to assist in the breakdown of a heavy scum layer?   Front end screening can aid in the removal of gross solids, followed by mixing which will keep the scum layer homogenized. Once homogenized a dissolved air flotation (DAF) or clarifier can be used to remove the solids prior to biochemical oxygen demand (BOD) treatment if needed. If there is at least a day of [...]

10 State Standards Update

The Great Lakes – Upper Mississippi River Board (GLUMRB) of State and Provincial Public Health and Environmental Managers have completed the 2018 Edition of the Recommended Standards for Water Works, commonly referred to as the 10 States Standards. Participating State and Provincial agencies meet on an annual basis to establish design guidelines for the waterworks industry. These policies act as guidelines [...]

Your Performance Index: Things are Not Always as they Appear – the Impact of Internal Filter Maintenance

Internal filter inspection is an essential part of any scheduled maintenance routine. The external view of your filters is not always an accurate representation of what is happening within. Consistent internal inspections will keep your plant running optimally and provide early detection of issues, that when resolved quickly can prevent the need for larger, more expensive repairs. Below you will find a list of [...]

Turning Data into Intelligent Action

Industrial consumers have more access to data than ever before, but what to do with it? Can advancements in technology really make us better tomorrow than today? This thought-provoking article will introduce a concept to building context into data to ultimately achieve intelligent actions or recommendations from computing systems. While our example will hit home for water treaters, the concept behind this process and [...]

What’s Trending: Design Build

Design build projects are not a new concept in the construction industry but is new to the water treatment industry. In recent years, an inflation of design build work has emerged within the marketplace and it’s expected to continue to gain momentum. So, what is a design build project? Design build projects often require bidding into a design build proposal rather than bidding directly to a contractor. This [...]

Benefits of Side Stream & Media Filtration in Cooling Towers

Cooling towers scrub large volumes of air and effectively remove solids consisting of dust, microbiological organisms, and various airborne debris. Tower water adds suspended solids in the form of corrosion products, microbiological growths and wood fibers from the tower and process leaks. If allowed to settle, these solids can generate many problems within the system. With heavy solids loading, even the best [...]

Cooling Tower Spring Maintenance

Winter layup of cooling towers can create an environment susceptible to growth and incubation of corrosion causing bacteria. Cooling tower cleaning and maintenance prior to spring start-up is recommended by OSHA to remove biofilm and prevent Legionella bacteria, and by most cooling tower manufacturers to maintain system efficiency during the summer cooling season. Cleaning and disinfecting the cooling tower basin [...]

Your Performance Index: The Importance of External Filter Inspections

Maintenance is vital to the success of treatment plants across all industries. External filter inspection on a regular basis will keep your plant running optimally and promote system longevity. Consistent inspections will catch minor repairs that when fixed in a timely manner, do not become bigger, more expensive repairs and also prevents a full plant shutdown. When inspecting filter exteriors, there a few things you [...]

Filming Amine Use in Multi-Metal Hot Water Systems

Corrosion in industrial and commercial water treatment continues to be a major concern as companies strive to reduce costs while maintaining their assets. The need to protect heat exchange equipment and associated piping is vital in minimizing operational costs and preventing downtime. Traditionally, copper and carbon steel have been the metallurgies of choice for comfort heating and cooling heat exchange equipment. [...]

Minimizing White Rust in Galvanized Cooling Systems

Galvanized coatings for cooling tower systems (cooling towers, evaporator tube bundles, etc.) have been used in the industry since the 1950s due to their relatively low cost and long service life. The galvanizing process bonds a layer of zinc metal to steel. When properly applied and passivated, the zinc coating works as a non-permeable sacrificial anode to prevent corrosion of the underlying steel structure. White [...]
