Every city is located in a unique physical setting, with specific environmental, climatic and geographic characteristics. Historically, when resources and technologies were limited, people adapted settlements to their surroundings, took advantage of local benefits wherever possible, used design and accessible materials to mitigate undesirable conditions, and recognized intrinsic limitations. This gave rise to the many regional variations among historic settlements, including distinct overall plans, urban forms, building materials and architectural character.
In the GDT™ process, high efficiency Mazzei® injectors aspirate ozone gas from a generator at 1-15% weight providing dynamic mixing and mass transfer. Dissolution is enhanced in a Flash Reactor™, determined for each application on the basis of feed gas concentration, operating pressure, reaction rates and desired transfer efficiency.
Achieving consistent water pressure is a challenge for geographical areas that have grown faster than the development of infrastructures to accommodate water demand and for businesses such as fast food restaurants and strip malls.

Partnering with Siemens provides the reassurance of best-in-class products, and the precision, integration and reliability in process automation to help you deliver optimum efficiency and productivity.
Micropollutants like PPCPs are known to pass through waterways and contaminate the environment. Some wonder what threat they pose as they find their way into biosolids and, eventually, into our soil.
Researchers from Iowa have developed a system that utilizes algae for wastewater nutrient removal and gives utilities a chance to offset costs with the process.
Updates to a seminal document for running water and wastewater utilities as efficiently as possible call for review by those facing new obstacles.
With the change in administration comes a potential paradox for water and wastewater treatment in the oil and gas industry: Will increased production accompanied by decreased regulations call for more treatment technology or less? Either way, the market is poised for change.
The U.S. EPA has updated the list of approved test procedures that can be used to analyze wastewater for compliance under the Clean Water Act.
A new best practices guide from the U.S. EPA provides discharge permit writers and pretreatment coordinators with tips on helping wastewater treatment plants deal with industrial effluent.

The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?
While the term “Water Resource Recovery Facility” may seem like nothing more than a trendy phrase, the name change represents a distinct shift in the role that wastewater utilities can now play.
Conversation at the 2016 SESWA Stormwater BMPs, LID and Green Infrastructure Seminar in Atlanta GA that I attended recently touched upon the idea of computers taking our jobs and ‘Engineering Bots’. This has of course happened in other industries, but I didn’t anticipate it happening in the stormwater planning, design and management world.
Living near water requires that we plan for situations when we have too much of it. Throughout history we have dealt with flooding when weather events exceed “normal” parameters.
