After anticipated growth of the New Jersey casino industry fell short, Atlantic City Sewerage Company’s Baltic Avenue Pump Station was left with grossly-oversized long-shaft sewage pumps that operated inefficiently and were prone to cavitation.

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.

VigorOx® WWT II is an equilibrium peracetic acid solution that contains 15% peracetic acid (PAA) by weight at full concentration. The solution exists as an equilibrium of PAA, hydrogen peroxide, acetic acid and water.

Lower tipping and hauling fees, plant and site odor, processing times and more for the waste industries.

The city of Auburn, AL has two wastewater treatment facilities – the Northside Water Pollution Control Facility and the H.C. Morgan Water Pollution Control Facility. In 2012, the H.C. Morgan facility was upgraded, and treatment was converted from chlorine to UV. This case study will provide you with details about the selection process, why our TrojanUVSigna™ was chosen, and how we helped simplified the conversion from chlorine.

In order to improve the efficiency of biofilm technologies, a high-performance biocarrier has been developed, based on requests for ideal carrier characteristics.

Inland Empire Paper Company (IEP), located in Millwood, WA specializes in the production of newsprint paper using a combination of mechanical pulp and recycled newspaper pulp. IEP produces an average of 525 tons per day of newsprint and specialty paper products in 20 to 40 pound weight paper. 

In the design of wastewater treatment plants, aeration typically involves supply of both oxygen and mixing. Aeration is a large consumer of both energy and operational costs. The Aire-O₂ Triton aerator/mixer is a process aeration technology that addresses both of these aspects and is environmentally friendly, which is a winning formula to help achieve long term sustainability. By Cheri D. Cohen, Aeration Industries International, Inc.

Supersaturated dissolved oxygen (SDOX®) can cut aeration-related energy costs in half for a range of applications, including activated sludge systems, oxidation ditches, odor control in collection systems, and more.

When it comes to pH measurement in water and wastewater treatment, there are two focal points for the word ‘standard’ — one is a compliance-related state or federal water quality specification; the other is a specific fluid used as a calibration reference point to ensure pH instrumentation accuracy. Here is why both are important and how they affect the best pH measurement outcomes in both areas.

As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

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.

Siemens offers to our customers the ability to make both process measurements, and to remotely monitor the activity and health of instrumentation, whether you have a SCADA, PLC or DCS system, or not. By utilizing Siemens’ ability to offer unparalleled flow, level, pressure, temperature, and weight measurement we can provide a broad range of process measurements and offer unequaled monitoring of the health and performance of those products.

A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.

Stockholm water company produces biogas from their wastewater facility which feeds Scandinavian Biogas for energy production. As they need to accurately meter what they sell to the energy facility they used a project contractor firm to engineer and define the best solution for the project.

Power plants and refineries around the world must manage and treat complex effluent waste streams from the Flue Gas Desulfurization (FGD) process. Flue gas is generated by the combustion process of fossil and fossil-derived fuels, such as coal, oils, and natural gas in power plants. Petrochemical refineries may generate flue gas from a number of different processes, including Catalytic Cracking, Steam Methane Reforming, and Heaters or Furnaces.

The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

Hydrogen sulfide (H₂S) gas in wastewater environments is a familiar concern. But waiting until its odor is detected can be too late to exert as much control over it as desired. Fortunately, a new ability to monitor H₂S concentrations — in the liquid wastewater stream, in real time — is advantageous for wastewater professionals in terms of safety, cost, and consumer complaints. Here are four ways to capitalize on that capability.

A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.
