WASTEWATER
What To Know Before You Invest In New Headworks Equipment
Successful headworks investments depend on understanding site needs, matching technology to application, evaluating total cost of ownership, and choosing vendors that prioritize long-term performance and reliable support.
WASTEWATER CASE STUDIES AND WHITEPAPERS

Creating Reusable Water From Municipal Sewage
Al Shamal is the capital city of the municipality of Madinat ash Shamal in Qatar. With the majority of the town's population not yet connected to a sewer network, there was an immediate need to provide a wastewater treatment plant to treat wastewater generated from the towns' population and small industries. Ashghal, the Public Works Authority of Qatar and its end user, decided to install a tanker discharge facility with a compact sewage treatment plant to produce effluent suitable for reuse in irrigation.

Rental Blowers Offer Proactive Approach To Aeration-Related Infrastructure Projects
As the nation’s wastewater infrastructure continues to age and the demands on its systems continue to grow, a proactive approach to upgrades and enhancements is paramount. However, important wastewater projects involving aeration systems have often been delayed by utilities because of the high costs associated with temporary air while the project unfolds. Rental solution providers can have a significantly positive impact on the overall cost of a project, allowing the work to move forward.

Earthquake Resistant Ductile Iron Pipe, Valve, And Hydrant System
Recently, ASCE released its Infrastructure Report Card, giving the nation’s drinking water infrastructure a D: in poor to fair condition and mostly below standard. Many water utilities and communities are doing the hard but necessary thing in finding the resources to upgrade their aging water infrastructure. And, for those in earthquake prone areas, hopefully considering an earthquake resistant system.

The Minimalist Guide to Water Quality Analysis For Biological Nutrient Removal
Nitrogen and phosphorus are two wastewater constituents that, together, pose one of the most high-profile threats for consumers and the environment. An abundance of these elements is what ultimately leads to the formation of toxic algae in surface waters, an environmental issue that regularly gains mainstream headlines and, in some cases, poses an acute health risk to consumers.

How To Size An Advanced Oxidation System For A Variety Of Treatment Options
While UV AOP technology continues to gain traction, there are few regulations or standards for it, making it difficult for engineers to specify equipment size for new installations.
-
The Key To Accurate Waste Gas Flow Measurement
Wastewater treatment facilities have a tremendous opportunity to utilize the biogas they generate to lower energy costs and minimize odors. However, the practice isn’t as widespread as it could be, as the precision gas flow and methane content readings required to optimize the process often clash with the misconception that biogas is messy and difficult to measure reliably. With the proper equipment, it is possible to accurately measure biogas to cut emissions and reduce or eliminate the energy bill.

This report describes the 2000PV through the 12" size.
LATEST INSIGHTS ON WASTEWATER
-
The White House has finalized plans to roll back rules under the National Environmental Policy Act (NEPA), narrowing its focus and limiting what the current administration claims are needless delays for federal approval of water, energy, and other infrastructure plans. For water and wastewater utilities, the changes could speed up permitting for critical projects, although experts warn the tradeoffs could do more harm than good.
-
Traditional sewer systems, while effective, often require significant capital investment, invasive implementation measures, and complex maintenance. As a result, innovative decentralized wastewater solutions are necessary to address the needs of communities or commercial areas in need of wastewater service. One such solution is the liquid-only sewer (LOS) system.
-
While many scientific and technical reports show that floods are becoming larger and more common, reports underestimate how their frequency is changing. Flood sizes get the spotlight, but governments and experts need to also consider their frequency to address implications overlooked by traditional management methods.
-
In areas with storm drains, the water can quickly overwhelm the drains, causing flooding hazards. For this reason, many towns have ordinances dictating how much ground can be covered with impermeable substrates.
-
Technology like advanced process control systems can streamline operations, create opportunities to lower costs and emissions, and ensure effluent quality meets the highest standards. Research also indicates that implementing an appropriate control strategy can help reduce N2O emissions.
