The City of Plymouth processes 150,000 gallons of raw sewage a day. Before 2009, the plant had no headworks installed at all. The raw sewage was being dumped into a pond. Because of this, the plant suffered major ongoing sludge and BOD problems. A city engineer recommended a new system be installed to combat these problems. After doing research, the engineer found a Franklin Miller system that proved a perfect solution.

Temporary water reuse systems help industrial plants avoid costly downtime by maintaining treatment capabilities during maintenance, failure, or testing—offering fast deployment, flexibility, and permanent-quality results.

A microbrewer’s expertise is in brewing, not engineering. Discover how you can get the most out of production lines without the costs associated with hiring outside engineers or experts.

Every waste treatment system in the world has a biosolids management issue.  For some it is just volume disposal; for others it is toxic disposal; for still others the issue is meeting the discharge requirements. By Chip Bettle, Absolute Aeration, LLC

Originally constructed from the 1920s to 1949, the Gulf Intracoastal Waterway (GIWW) is one of America’s most remarkable transportation arteries. The New Orleans District U.S. Army Corps of Engineers operates and maintains the GIWW in Louisiana, and maintains its six locks for both navigation and agricultural purposes.

Replacing mechanical seals twice per year was difficult and expensive for Chester, IL, but a more serious problem occurred when the seals failed with the Mississippi River at flood stage and the sealed lift station underwater.

After researching different ozone systems, plant officials ata 12 MGD wastewater plant in Arkansas chose to install BlueInGreen’s HyDOZ technology in order to more efficiently meet current permit requirements, as well as prepare for future legislation.

Comminution technology has been evolving quite rapidly in response to the increasing burden entrained solids have placed on treatment facilities. More advanced devices have been developed in rapid succession. The result has been an exciting and fluid race between the leading manufacturers to develop the best size reduction device. The latest grinder innovations to be introduced have coupled the power of twin shaft grinding with higher flow capabilities and screw screening systems. Here’s a rundown on the past and present state of the art in wastewater solids reduction.

Accurate flow measurement is critical for process control and regulatory compliance. Flow meters are essential instruments for water and wastewater facilities, installed at multiple locations throughout entire systems. For the most part, these are permanent installations. However, portable flow instruments prove beneficial in certain situations.

The Emerald Coast Utilities Authority (ECUA) was having a difficulty with their sewage grinders. They were running four grinders supplied by a well known manufacturer at two of their pump stations, with each station processing approximately 10 mgd. Unfortunately, their first set of grinders turned out to be problematic. They created a lot of down time and generated excessive maintenance costs. ECUA needed a new solution to solve their problems and get their pump stations functioning properly.

In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.

Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

Waste water, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial wastes.

Leaks found in 60 psi high density PE pipe by FELL in less than three hours. Acoustic and CCTV failed to find any leaks after more than a year of investigation. Read the full case study to learn more. 

Flex-Tend flexible expansion joints have a proven record of providing protection for pipelines subject to subtle or sudden movement. As with all products used in the water and wastewater industry, protection is optimized with the selection of the proper assembly incorporated into a sound design. This paper is intended to provide assistance in both of these areas.

Water and wastewater piping come in a variety of materials, joints, and diameters. They can meet a multitude of demands and needs for the country's infrastructure.

Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.
