White Paper: Surface Aeration Revisited The intention of this paper is to have a critical review of the theory and practice of today’s Waste Water Aeration Technology

How The Ukiah Wastewater Treatment Plant Solved Its Debris Problem

The water treatment needs of both Ukiah Valley and Lake County are served by the Ukiah Wastewater Treatment Plant. Nestled between Highway 101 on the west and the Russian River to the east, the facility features a scenic view of surrounding valleys of vineyards seemingly out of a Steinbeck novel. Construction of the facility was completed in 1958 back when the city had a population of around 9,000. Since then, the population has grown by about 78% to a total of 16,000 residents. The plant’s five pumps are equipped to handle 2.8 MGD (million gallons per day) of dry weather flow, and 20 MGD of wet weather flow. Even though the plant is equipped to remove some floating material, they were having issues with an overflow of unwanted debris.

Crusher Provides Cool Solution Freeze Dried Mushrooms

When establishing a processing and freeze-drying system for an exotic mushroom customer, Van Drunen Farms in Momence, Illinois found themselves in search of a solution for a unique set of challenges.

Optimizing Aeration Reliability In Food And Beverage Wastewater Applications

In addition to penalties for non-compliance, wastewater treatment plant (WWTP) operators in the food and beverage industry risk excessive losses caused by problems at the wastewater treatment facility.

Case Study: Prosonic S Provides Reliable Control Of Filtration For Raw Sewage Water

In the inlet of the plant, the raw sewage water is filtered through 3 automated systems. The filtration systems are equipped with an endless mesh, which captures the solid materials. By Endress+Hauser, Inc.

Treatment Of Produced Water By Electrocoagulation

Produced water (PW) is salty water trapped in the reservoir rock and brought up along with oil or gas during production. It subsists under high pressures and temperatures, and usually contains hydrocarbons and metals. Therefore, it must be treated before being discharged to surface water. Different techniques are being used to treat PW through phase separations, system control and design, and chemical treatments. In this paper, we discuss our experimental results on treating PW through electrocoagulation (EC).

Increasing Capacity: AE-DENITRO + Hydrotech Discfilter

The City of Palm Coast, located on the east coast of Florida, expanded their existing Wastewater Treatment Plant (WWTP) to increase capacity to 6.83 MGD due to population growth, as well as add the production of reclaimed reuse water for use within the City.

White Paper: Challenging Urban BMP Assumptions There are two broad classifications of structural Best Management Practices (BMPs). This paper is concerned with devices or techniques that are intended to capture and hold materials that can be separated by gravity, buoyancy, screening, and skimming.

Using ATP In Suspended Growth Wastewater Treatment Systems – What Is The Benefit?

Suspended growth systems, such as activated sludge, are a very common form of secondary wastewater treatment. The potential to optimize and improve the operation of such treatment plants using ATP is tremendous. ATP can directly quantify active biomass, which is key to providing secondary treatment. Two of the many potential uses for ATP in a wastewater treatment plant are aeration and solids optimization and toxicity monitoring and identification.

The Savings Are Blowin' In At Port Washington Wastewater Treatment Plant

The municipal wastewater treatment plant in Port Washington, Wisconsin, is located on the picturesque shore of Lake Michigan, so it’s essential that their plant performs as designed.

Filter Installations Remove Solids From FGD Scrubber Effluent

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.

Textile Manufacturing

The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

Panametrics Achieves Challenging Wastewater Flow Measurement On A Lined Ductile Iron Pipe

A municipal wastewater plant in North America sought a reliable flow measurement for one of their key wastewater lines. The existing dual-channel ultrasonic flowmeter from a competitor had consistently failed to provide accurate readings.

Instruments For Environmental Applications

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.

Recording & Control: Aeration Control In Wastewater Plants – Accurate And Fast Control Of Aeration Process

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

Pikeville, Kentucky Medical Center Leak Found Despite Ambient Noise

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. 

Ultrasonic Flow Meters Improve Biogas Measurements

As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.

Scrubber Application

This customer supplies district heating and electricity for the region of Sønderborg. For one of their waste applications a MAG meter failed within 6 months, and was successfully replaced with a Panametrics Aquatrans AT600.

Remote Monitoring And Maintenance Through Digitalization

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.

Lab Gas Sub-Metering Accuracy Improves With Thermal Flow Meters To Save Money

Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.
