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.
Toward a renewable future
energy, and nutrients are at the heart of the challenges that must be addressed
to meet the needs of the ever-increasing global population. The wastewater or
“used water” sector must not only continue to provide high-quality effluent to
protect human health and the environment, but also find ways to tap into
previously overlooked sources of water, energy, nutrients, and other
Nutrient removal remedies
Consistently meeting low permit limits for nutrients can sometimes challenge even the most experienced facility personnel. Optimizing TN and TP removal requires an understanding of the chemical species of each nutrient, their expected concentrations throughout the process, the basic concepts of the processes designed to reduce them, and the interaction of components within the treatment facility. Having knowledge of process controls, and understanding how to apply them to daily facility operations, is essential for achieving low concentrations of nutrients — and doing so consistently.

Bigger footprint, smaller world
profile of the water sector is growing. Cities, businesses, and even the public
are beginning to pay water the attention is deserves. But simultaneously, the
water sector itself is undergoing a consolidation and transformation. In more
places, drinking water, wastewater, stormwater, groundwater, reclaimed water,
and every other type of water are unifying through integrated planning.
Centralized assets, operations, maintenance, and financing provide new
opportunities, but also new challenges.
the May issue, the article, “The promised and the practical,” examines a New
England perspective on integrated planning and permitting. Several communities
are exploring an integrated planning approach. The obligation to engage
multiple stakeholders and address the regulatory mandates for myriad planning,
engineering, and natural resource interests requires municipalities and
agencies to push beyond traditional solutions.
the operations level, integrated planning also can lead to gains. “Scottsdale
seeks one water” describes how an organization sought to meet higher customer
expectations, stricter regulations, and stiffer economic pressures as well as
face a more demanding workforce and increased environmental concerns at an
affordable price. This utility’s optimization program is helping to manage
these challenges now and into the future. The program brings all utility
operations — water, wastewater, reclaimed water, water quality, engineering,
planning and scheduling, and others — together under one holistic system.
Also in this issue:
Operator ingenuity. Operators find a simple fix to avoid pump
From crisis to opportunity. Emergency rehab leads to cutting
aeration treatment costs by 43%.
Appreciating operators. Utilities recognize the
professionalism of the sector’s workforce.
A secret hidden in plain sight. Competitive bidding is an
often-overlooked strategy for controlling electricity costs.
