Cost-Effective Sludge Thickening Processor Using MEMBRAY™ Membrane Bioreactor
The Valley Center Municipal Water District (VCMWD) operates two wastewater treatment facilities in Valley Center, which is located in the northern part of San Diego County, California. Both WRF's incorporated an in-house membrane thickener (MBT) design and selected Toray's MEMBRAY™ Membrane Bioreactor (MBR) modules for the process. VCMWD's objectives were to conserve water and meet the Regional Water Quality Control Board's effluent standards (Title 22), so the reclaimed water can be used for irrigation and other reuse applications. The MEMBRAY™ MBR modules helped the local utility achieve these goals.
Taiwan Mandates Water Reclamation For Economic Sustainability
As a leading global supplier of semiconductors and other related IT components, access to a consistent supply of clean water is essential in Taiwan for sustaining a growing economy. However, in 2015, the country experienced one of the worst droughts in its history. Combined with frequently occurring typhoons that hamper the availability of clean water, this sparked the government to implement countermeasures immediately. Read the full case study to learn more.
50+ Links To Assist Small, Stressed Water Utilities
While any drinking water or wastewater treatment operation can be challenged by demands from changing seasonal conditions or regulatory requirements, those pressures can quickly compound for personnel forced to wear multiple hats at small- to medium-sized utilities. Here are scores of links to helpful resources for such operators for the municipalities and consulting engineers who work with them.
Preparing To Tackle The Hydra Of LCR Revisions
As a journalist serving the water industry — but not yet a seasoned technical veteran — I attended a recent Lead In Drinking Water Forum sponsored by AWWA NJ to learn about the challenges of complying with the proposed Lead and Copper Rule Revisions (LCRR). What I heard impressed upon me the technical, administrative, and logistical challenges of delivering safe, lead-free drinking water all the way to user taps. Here are my takeaways.
Congress Ends The Year With A Splash
Congress ended 2019 with a splash, culminating in a budget for Fiscal Year 2020 (FY-20), House passage of the U.S-Mexico-Canada Agreement (USMCA) on trade, and impeachment of the President of the United States.
What To Watch As The Texas Legislature Takes Up Climate, Energy, Water, And More
We’re past the midpoint of the Texas legislative session and the bill filing deadline is behind us. Because the legislature only meets for five months every other year, there’s a lot to accomplish in a short span.
EPA's Looming Risk Resilience Assessment (RRA) And Emergency Response Plan (ERP): What You Need To Know
The U.S. EPA has a new Risk Resilience Assessment (RRA) and Emergency Response Plan (ERP) compliance deadline coming for water systems across America. These key plans are set to come due in 2020 and 2021 with varying deadlines as per the size of the utility’s service areas. This article will give you tips to be ready for the EPA deadlines.
How The EPA Reacts To A Government Shutdown
Did you know that the Environmental Protection Agency (EPA) had a published Contingency Plan in anticipation of the current government shutdown? I guess in hindsight, you would have expected it for an agency with 134 facilities dotted across the country. And in fact, it’s required by the Office of Management and Budget (OMB) under Circular A-11, Section 124 that all government agencies have plans for an orderly shutdown “in the event of an absence of appropriations.”
Getting Serious About Lead Service Line Replacement
It has been 32 years since the amended Safe Drinking Water Act (SDWA) banned the installation of lead pipes in water systems nationwide. Unfortunately, that decision has not yet translated into action for every lead service line (LSL) installed before that point. Fortunately, someone has done a lot of legwork toward getting a handle on that process. Here is a preview of the help they have to offer.
Activated Sludge Treatment In A Municipal Sewage Treatment Plant
A design/build contractor needed a quiet, efficient aeration system for a 250,000 GPD field erected WWTP that was to be located adjacent to a school. A restriction on ambient noise at the location of the proposed WWTP required a quiet aeration process. Read the full case study to discover how Mazzei solved the problem.
