Water Environment & Technology (WE&T) is the premier magazine for the water quality field. WE&T provides information on what professionals demand: cutting-edge technologies, innovative solutions, operations and maintenance, regulatory and legislative impacts, and professional development.
Remediation to the Rescue
After failing to meet its discharge permit limits, District 1 of Savannah, N.Y., faced a tough decision: Replace its old sand filter at a significant cost to the community or face a consent order. The district decided to pursue an alternate course.
Used to inject treatment chemicals in virtually every water and wastewater facility, metering pumps should be considered separately from virtually every other type of pump. Metering pumps have undergone several distinct technological
changes during the past 60 years, compared to most other pump types, which have evolved little during this period. Changes in the way a metering pump operates truly have expanded the scope of what a metering pump can achieve.
Engineering and the Glass Ceiling
A woman engineer may not have to “be a man” to succeed in today’s world. But being a woman can still hold her back in her career, according to a new U.S. National Academy of Sciences (NAS) report on women in academic science and
engineering, Beyond Bias: Fulfilling the Potential of Women in Academic Science and Engineering.
