Getting the most out of WEFTEC

A sample schedule shows the breadth of topics presented

The numerous choices of educational activities and events to attend at WEFTEC® 2011 can be overwhelming, especially for those new to the Water Environment Federation (WEF; Alexandria, Va.) technical conference and exhibition. To help attendees get the most from WEFTEC, WE&T has prepared a sample schedule that maximizes learning opportunities in a broad range of wastewater treatment topics.

Nutrient compliance and a bigger carbon footprint?

carbon footprint art

Lowering nutrient loads helps to prevent eutrophication, which has its own serious, negative impact, but in doing this, wastewater treatment plants (WWTPs) may worsen other environmental impacts, including carbon footprints. WWTPs can use life-cycle assessment (LCA), a technique that measures the direct and indirect environmental impacts of a specific process, to compare and balance these effects.

 

Exam in progress

Voluntary and mandatory environmental certification and licensing programs  benefit the profession by documenting an individual’s professional competence and showing that individuals have met industry certification standards. Even though significant differences exist among certification programs, there are key resources and strategies that can help all applicants in the quest to become certified.

Green infrastructure, numeric limits are among recent trends shaping the stormwater field

As a relatively new discipline, stormwater management continues to undergo significant shifts in approach and emphasis as scientific understanding changes and experience suggests potential improvements. With the scheduled release this fall by the U.S. Environmental Protection Agency (EPA) of its long-awaited stormwater rulemaking, stormwater management practices in the United States can only be expected to experience further change.

Stormwater: treating and reducing CSOs

In many municipalities, wet weather flows are a huge stress on collection system capacity. Utilities that are striving to manage combined sewer overflows (CSOs) have a number of options in treatment technologies and operations strategies.

Treating CSOs is a regulatory requirement in many regions. While chlorine traditionally has been used to provide disinfection for CSOs, ultraviolet (UV) light can be a cost-effective alternative. Learn more about UV reactor design for stormwater and other wastewater applications.

Some utilities concentrate their efforts on capturing wet weather flows in existing infrastructure for later treatment. For instance, the Lowell, Mass., Regional Wastewater Utility has reduced CSOs significantly. The utility installed flow depth sensors and an automated gate control system and changed its operating philosophy to maximize in-line storage.

Nutrient removal: meeting new effluent limits

Wastewater treatment plants that discharge into nutrient-sensitive watersheds face strict new regulations requiring enhanced removal of total nitrogen and total phosphorus. Learn more about the nutrient removal strategies utilities are implementing to maximize plant performance. The October issue focuses on technologies that can achieve ultralow nutrient removal — from oxidation ditches to reverse osmosis — as well as supplemental carbon sources.
