Toward a renewable future

Feature 1 art Water, 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 commodities. 

 

Nutrient removal remedies

Feature 2 art 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


The 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.
 

In 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. 

At 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 cavitation.
  • 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.
