Chesapeake Seals the Deal

The City of Chesapeake, Va. is located in the region called Hampton Roads, the 27th largest metro area in the country with more than 1.5 million residents. With an annual rainfall of approximately 48", its designers must contend with the prospects of determining where 294 billion gallons of water will go. A large share of this rainfall will find its way into the storm sewers. Last year, the City Council appropriated an extra $467,600 for contract cave-in repairs. The City of Chesapeake has recognized this problem and is developing a program to address it.

Greensand Process Removes Iron, Manganese, Arsenic from Groundwater

Manganese greensand is a specially processed medium for iron, manganese, and hydrogen sulphide removal. This premium non-proprietary filter medium is processed from glauconitic greensand on which a shiny, hard finite thickness manganese oxide coating is formed and is firmly attached on every grain by a controlled process.

Filtration Fundamentals

Over the years, water quality has noticeably deteriorated worldwide. This decline in water quality stems from the extreme demand on very limited natural resources. Various principles of filtration are used in many applications to improve the general quality of the water that is being treated. Along with screen filters, coagulation/filtration, neutralizing filters, oxidizing filters, clairifying filters and carbon filters are other treatment methods that may be used.

Zero Waste: A Look at the Future of Reverse Osmosis

Most reverse osmosis systems waste as much as 20 gallons just to produce one gallon of product water. The new technology called "ZeroWaste" eliminates this problem by returning the concentrate water from the reverse osmosis system back to the home's plumbing, resulting in 100 percent efficiency.

Integrated Technology Simplifies Dewatering Process at Two Municipal STPs

The borough of West Mifflin, Penn., is a community located about nine miles southeast of downtown Pittsburgh. For years, the West Mifflin Sanitary Sewer Municipal Authority (WMSSMA) hauled liquid from its New England STP (a 1.2 mgd plant) to the Thompson Run facility (a 4.5 mgd plant), where it was processed on a belt press for dewatering. However, the hauling and associated labor proved very costly, and it was not always easy to coordinate dewatering schedules for both plants.
Additionally in the late 1990s, the WMSSMA faced a requirement to achieve higher cake solids and provide odor control that would respect nearby homes and businesses. Moreover, space constraints and staffing reductions necessitated a simple-to-operate installation.

Municipalities Tap into Benefits of EDR Water Treatment

No one wants to drink radium, nitrates or arsenic. However, if not for some technologically advanced methods of removing these contaminants, we all might be sipping on some very unhealthy water.

Point-of-Use Reverse Osmosis

As the residential point-of-use (POU) reverse osmosis (RO) industry approaches its 35th anniversary, it is time for a reality check on the industry's progress to date as well as a look ahead to new technologies or improvements that the industry may introduce for POU RO systems in 2003.
