Global Approach To Wet Weather Issues: Key Steps To An Improved Water Quality

Wet Weather issues have evolved over the last generation. From an environmental side issue twenty years ago, they have gained the forefront of environmental concerns. This paper will present the key steps to achieve a global approach to Wet Weather issues. Each of the best management practices available have been ranked and reduced to critical steps that can be implemented sequentially in order to achieve an optimized global approach to wet weather issues.

CeraQ Ceramic Membranes Provide Robust Solution For Automotive Parts Manufacturing

An automotive parts manufacturing plant was using a polymeric membrane to remove oil from water it used to rinse parts. The rinse water contained between 6% and 7% oil and the customer wanted to remove >95% of the oil from the water so the water could be reused in the plant.

Would You Like Some Free Green Energy With That?

Some of the world’s most environmentally efficient and profitable green energy technologies are being specifically tailored to the needs of the beef, poultry, pork, rendering and stockfeed industries.

Custom Solutions For Reuse Applications

As supplies of fresh water become increasingly scarce, methods of recycling and reusing this vital resource are getting more attention than ever before. Orenco’s AdvanTex Treatment Systems consistently produce clear effluent that meets the most stringent permit limits.

Interceptor Sewer Rehabilitation In Lucas County, Ohio

Rehabilitating the Lucas County Interceptor Sewer No. 500 was a two-phase project. The most recent phase required a solution that would be impervious to the corrosive influences found in these environments. 

Join Hydro International For The Vortex Flow Controls In Practice Webinar

In this follow-up webinar Technical Product Manager, Phil Taylor will demonstrate in more detail how to select and design a Hydro-Brake using our free online design tool. The Hydro-Brake is one device that should be in every stormwater engineer’s toolbox. Hydro invented the vortex valve back in the 1960’s and has led the world in its development and design ever since.

City Solves Wastewater Plant Dilemma With Dynablend™ Liquid-Polymer Technology

The City of Marengo, Illinois operates an activated sludge wastewater treatment plant that processes an average volume of 1.8MGD with a maximum capacity of 5.94MGD. In the fall of 2007, the operators of the plant began to observe reduced performance of their liquid-polymer feed system that was in place at the city’s facility. The Dynablend™ liquid-polymer unit was a good fit for the Marengo plant because of its reliability and performance over a wide range of polymers commonly used for sludge processing. Read the full case study to learn more.

Boosting Accuracy For Long-Term SSO And CSO Planning

Accurate flow measurement is increasingly imperative for sanitary sewer overflows (SSOs) and combined sewer overflows (CSOs), which are a rapidly growing area of concern for municipalities.

Advanced Circulation Technology Combined With Solar Power Cuts Expensive Aerator Run-Time And Provides Efficient Mixing In Wastewater Treatment Ponds

The energy and maintenance costs associated with mechanical aeration are compelling managers of municipal and industrial wastewater treatment plants (WWTP) to find alternate technologies. The goal is to provide more efficient wastewater aeration and mixing by reducing high operation and maintenance costs associated with mechanical aerators. By Joel Bleth, president, SolarBee Inc.

Z-92®/Z-33™ Uranium-Arsenic Treatment Process - Schurz Elementary School, Nevada Case Study

This uranium, arsenic and gross alpha removal pilot study was conducted for the Schurz Elementary School treatment facility in Schurz, Nevada. The Schurz Elementary School well contains concentrations of uranium, arsenic and gross alpha in excess of the State regulated Maximum Contaminant Levels (MCL).

Reducing Total Phosphorus In Water Resource Recovery Facilities

Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.

Dissolved Oxygen Measurement In Wastewater Treatment

A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.

Process Monitoring And Control For Increased Productivity And Efficiency

The Littleton/Englewood wastewater treatment plant, Colorado, put in place processes to effectively monitor the levels of ammonia in their wastewater treatment.

AquaSBR Sequencing Batch Reactor: Food And Beverage Industry

This application note explores Sequencing Batch Reactor (SBR) systems that have been installed worldwide in a variety of applications, ranging from a few gallons per minute (GPM) to thousands of GPM.

What Are You Doing To My Pipe: Can PVC Pipe Be Loaded?

The argument has been used that PVC pipe is delicate and can’t be subjected to any kind of loading. In EBAA's years of testing we have found that is not the case at all. PVC can take an extreme amount of strain.

Removal Of PFCs With Activated Carbon

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).
