New RO membranes tested on Red Sea, Egypt

Speciality chemicals company LANXESS has launched its Lewabrane seawater reverse osmosis membranes following testing on the Red Sea in Egypt. Deutsche MeerwasserEntsalzung (DME) GmbH, a Duisburg-based company were contracted by LANXESS to conduct the tests. The Lewabrane RO S400 HR elements underwent testing in Sharm El-Sheik, Egypt in a commercial, industrial-scale desalination plant, and an extensive set of conclusive data has been collected during this time. Three different elements with high rejection rates (HR) are currently available: Lewabrane RO S400 HR, S440 HR and S085 HR 4040.

Submerged UF membranes for MBR

Membrane technologies company QUA has launched the EnviQ™ submerged ultrafiltration membranes for wastewater treatment and recycle applications as part of the Membrane Bioreactor (MBR) process. EnviQ's includes features such as reverse diffusion and specially designed air diffusers. QUA said EnviQ significantly lowers the total installed cost of biological wastewater treatment and recycle systems as compared to conventional activated sludge processes with tertiary filtration. EnviQ is currently offered in three configurations: E-8C, 16C and 32C, each having surface area of 80, 160 and 320 m2, respectively.

Hollow fibre UF used to retrofit Del Rio plant

Koch Membrane Systems has started-up the initial phase of its retrofit to the ultrafiltration (UF) system at the City of Del Rio's water treatment plant located in Del Rio, Texas. The full retrofit project is scheduled to be completed over the course of a year. In 2003, the city commissioned a new Aquasource brand UF membrane filtration plant in response to the Interim Enhanced Surface Water Treatment Rule (IESWTR) and recommendations by the Texas Commission of Environmental Quality (TCEQ). By 2011, the plant's original UF membrane cartridges were showing signs of wear, requiring frequent fiber repairs. Following successful testing of Koch Membrane Systems' TARGA II UF membranes, it was determined that a retrofit could be implemented with minimal modification to the existing system.

Clearing Things Up at Prequannock WTP

In 2010, the city of Newark, N.J., retained Hatch Mott MacDonald to investigate potential solutions to a problem at Pequannock WTP. Decant tanks were providing minimal solids removal as a result of removed tube settlers from deterioration. Inclined plate settlers were identified as a feasible alternative for improving supernatant water quality and were selected for pilot testing.

Be the Change: Embracing New Approaches to Foster Innovation in the Water Industry

The pressure to accommodate change will drive our traditionally risk-averse industry to embrace new and different approaches at an accelerated pace. Further, the demand for a zero-energy footprint will also drive improvements in co-generation efficiencies, energy conservation and recovery methods, and comprehensive resource recovery.

CDC preparing Ebola guidance for wastewater treatment personnel

In a recent conference call with AWWA and other major water organizations, the CDC shared it has prepared and is conducting an expedited internal review of an interim guidance on wastewater worker safety and the inactivation of the Ebola virus by wastewater treatment processes.

New partnership to measure farmers' conservation impacts on U.S. water quality

The U.S. Department of the Interior and U.S. Department of Agriculture have announced a new partnership that will provide a clearer picture of the benefits of farmers' conservation practices on the quality of the nation's waters.
