How To Avoid The Biggest Wastewater Aeration Mistake

It’s common for wastewater treatment plant operators and design engineers to get comfortable with one type of blower for aeration. However, multiple blower technologies are available to consider when designing a new system. Understanding the difference between them, as well as the pros and cons of each based on the specific application, is critical to the decision-making process.

SEPAREL Available In External Perfusion And Internal Perfusion Varieties

SEPAREL hollow fiber membrane modules from the DIC Corporation provide exceptional degasification performance with a proprietary non-porous membrane which utilizes a Surface Skin membrane (SS membrane) for enhanced degasification. Available in both internal perfusion (PF series) and external perfusion (EF Series) varieties, SEPAREL modules are optimized for a variety of degassing applications.

Expanded Use Of Split Seal Technology For Large Pumps And Agitators New advances in split mechanical seals have expanded its application for use in both water and wastewater systems. These systems move vast amounts of fluid through pipes and tanks. Water-based fluid systems comprise the largest fluid transport systems in the world with wastewater streams being the largest. While the systems’ designs can vary by region, most use centrifugal pumps to move fluid. Many of the centrifugal pumps are very large and difficult to assemble, so they have not typically been sealed by mechanical seals which require total equipment disassembly. However, split mechanical seals have advanced so that these pumps can now be sealed without equipment disassembly.

Identifying Accurate Reference Materials For Water-Testing Confidence

Going through the motions of water sample testing for regulatory reporting requirements is only half the battle. It is also important that water operators use appropriately qualified reference materials and procedures to ensure the accuracy and reliability of their results. Here are some insights into reference-material evaluation that can generate the highest confidence in water testing results.

Design Considerations For Packaged MBR Systems

Applying Membrane Bioreactors (MBR) in lieu of conventional activated sludge systems delivers higher effluent quality while eliminating secondary clarification processes. These systems incorporate flat-sheet or hollow-fiber membranes with pore sizes measured in micrometers or nanometers, which allow for complete retention of solids inside the treatment system.

Water Plant Upgrades: 4 Reasons To Break The Re-Order Habit

A large percentage of the flow meters purchased for municipal water plants are replacements for older meters in existing facilities or distribution systems. It’s a common practice to replace aging meters with the same technology, often from the same manufacturer.

IMS Biological Odor Control Systems Protects The 2013 Sustainable GCC Project-Of-The-Year From Odors

Olayan Voltas Contracting Company was awarded the 2013 “Sustainable GCC Project-of-the-Year” by MEP Middle East magazine for the utility complex at Al Bustan Village, a brand new residential community north of Riyadh, Saudi Arabia.

Centerfeed Fine Screen Dramatically Increases Throughput

The Rotamat screen has been a popular choice for protecting debris sensitive technologies downstream such as MBRs. Through a constant program of responding industry needs, Huber Technology has developed the RPPS Star Pro series centerfeed fine screen. When combined, the Star and Pro options for the RPPS increases capacity and enables for even finer perforations, allowing for increased screenings removal in a tighter footprint.

Wireless Lift Station Monitoring Application Note

Powerful Pump Monitoring for Optimal Lift Station Performance. Trimble Unity software combined with the Telog wireless, battery-powered, multi-channel recording telemetry system provides a GIS-centric cloud and mobile platform for monitoring lift station pump on/off cycles along with sump levels. Clamp-on current sensors monitor pump run on/off to one second resolution. 

VFD Energy Savings For Pumping Applications

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.

How One Wastewater Treatment Plant Saved Time And Money Measuring Turbidity And TSS The wastewater treatment plant of a major corporation is designed for a population capacity of 6 million people and is considered a very large wastewater treatment plant.

Thermal Flow Meters For Mixed Gas Applications

Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.

Control Of THMs With Chlorine Dioxide

Chlorine dioxide (ClO2) is effective as both a disinfectant and an oxidant in water and wastewater treatment.

Harmonics Reduction Methods

There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.

Reduce SBR Maintenance Costs With Jet Aeration

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.

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.

Alcoholic Beverage Fusel Alcohol Testing With Static Headspace

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.

Determination Of Hexanal In Foods Utilizing Dynamic Headspace

Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.
