Businesses today operate in an environment characterized by change, complexity, uncertainty, and anxiety (Friedman 2005). All employees in all industries must be empowered to achieve optimal performance through effective actions, decisions, and problem solving (Figallo and Rhine 2002). No industry is more typical of this than the wastewater industry. And the Detroit Water and Sewerage Department (DWSD) faces the same challenges common to all wastewater utilities: losing knowledgeable staff, renovating and replacing aging facilities, sustaining compliance, and constraining rate increases. DWSD management has recognized knowledge management (KM) as a key business strategy to help address these challenges, and has proactively focused resources to take KM throughout the organization, from management and first-line supervisors to field operations and maintenance staff.
By investing in new technologies and infrastructure, together they can help reduce problems associated with water shortages
While both humans and their commercial operations rely on fresh water more than ever, sources of clean water are becoming scarcer. Climate change, droughts, increasing agricultural needs, water pollution, and global economic and population growth all contribute to frequent freshwater supply disruptions.A recent report by Barclays, a transatlantic bank, maintains that the energy industry, a...
In this study, anaerobic granular sludge (AGS) was used as a novel adsorbent for hexavalent chromium (Cr (VI)) removal from aqueous solutions. Factor experiments were conducted to find out the effects of different variables on the biosorption process. Among these terms, the impact of three main independent variables (contact time, initial pH and AGS dosage) on the removal efficiency of Cr (VI) was modeled using a well-fitting polynomial equation (R2 = 0.9044), by conducting 20 batch experiments designed by a...
Energy costs for water utilities are large, and growing
Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of annual costs. But water and wastewater utilities can generate and export energy – in multiple forms.

Water Innovations utilizes a 2-stage Cyanide Oxidation (CN) system that can treat from 2 GPM to 10 GPM. In the first stage of treatment, hypochlorite oxidizes cyanide to cyanate. It consists of two double-wall “Batch” Cyanide Oxidation Tank and an accumulation tank for cyanide-bearing rinse water, each tank equipped with one mixer. Wastewater containing cyanide will be pumped or flow by gravity into the first tank and then on to the second tank for complete cyanide oxidation. Both tanks have liquid...
Shared sanitation facilities are often the only feasible option for sanitation provision in informal settlements. When implementing infrastructure for wastewater collection and treatment, information regarding quantities and constituent loadings is required. Up to now, such data are not available for shared sanitation. In order to provide this information, this study focuses on wastewater characteristics of a shared sanitation facility in North Namibia. The input data used for planning are compared with monitoring...
