Updated Guidelines Reflect Growing Interest in Water Reuse
The new 2012 edition of the Environmental Protection Agency’s Guidelines for Water Reuse reflect the growing interest in water reuse in the United States and around the world. The guidelines, released earlier this month, include a host of case study examples to illustrate that trend.
New Orleans Assesses Damage from Hurricane Isaac
Two weeks after Hurricane Isaac swept ashore in Louisiana, a preliminary damage estimate put the toll at about $68 million for infrastructure controlled by the Sewerage and Water Board of New Orleans.
Pump Company Aids in Flooding Relief
There were five coastal parishes, among others, affected by Hurricane Isaac.
Examining Payback on New Generation High Speed Blowers
Upgrading to the latest aeration system or blower technology can help utilities cut operating costs and streamline operations. ‘Next generation’ aeration blowers are 10 to 20 percent more energy efficient than previous systems.
Cloud-Based Scada Offers Alternatives to Traditional Systems
Cloud-based SCADA is an alternative for the water and wastewater industry. It can help utilities limit the need for hardware and software purchases, installation and maintenance. A cloud-based service shifts the task of housing, maintaining and displaying data from the municipality to the service provider.
Web-Based Software Provides Cross-Platform Compatibility
Replacing a full supervisory control and data acquisition (SCADA) system is a big undertaking. The SCADA system at Western Municipal Water District’s southern California wastewater plant was no longer sufficient for their needs, so staff began working with a California-based systems integration company to implement a new system.
New Radio System Speeds Data Transfer
The Padre Dam Municipal Water District in California recently upgraded its wireless monitoring system with ProSoft Technology Industrial Hotspot Radios in mid-2010, greatly improving the speed of data transmission.
Media Upgrade Helps Eliminate Polymer in Arsenic Removal System
Plant and operations management for an 18 mgd arsenic removal water treatment plant in Corcoran, CA, have replaced filter media in their pressure filtration system to complete the process of eliminating a costly and troublesome polymer addition. As a result of the media change in the arsenic removal system, arsenic concentrations dropped from the range of 6-8 ppb after polymer cessation, down to a range of non-detectable to 5 ppb.
NWRI Publishes UV Disinfection Guidelines
