The Deep Tunnel Sewerage System (DTSS) is an efficient and cost-efficient solution to meet Singapore’s long-term needs for used water collection, treatment, reclamation and disposal. Conceptualised and managed by PUB, Singapore’s National Water Agency, it was conceived as a cost-effective and sustainable solution to meet Singapore’s long-term used water needs.

A balanced wastewater process is a beautiful thing — plenty of biochemical oxygen demand (BOD), plenty of O₂, and all those hungry little microbes are fat and happy. But what can be done when dissolved oxygen (DO) takes a nosedive and there’s not enough O₂ to satisfy industrial and food processing BOD? Here are some preparations to consider before wastewater treatment goes completely out of whack.

Confronted by everyday operating challenges, many decision-makers at drinking water and wastewater organizations do not always have all the time they would like to develop big-picture strategies and tactics for current and long-term concerns. Fortunately, multiple dedicated water-advocacy organizations do. Here are seven areas where water strategists, decision-makers, and other leaders can benefit from those valuable insights.

The Salisbury Township, Pennsylvania WWTP discharges into an unnamed tributary which leads into the Pequea Creek Watershed as part of the Susquehanna River Basin.

Clean water is a necessary resource for life, business, and the environment in which we live throughout the world.

The Hudson River, in the Capital District of Albany, NY, is a popular recreational area for boating, swimming and fishing. Unfortunately combined sewer overflows following storm events and snow melt from sewer systems dating back to the 1800’s were causing increased fecal coliform counts which in turn resulted in health alerts and limited access to the river. After considering several alternatives, the Albany County Sewer District selected a Wedeco Duron 60i2-2.5X4, with high power Ecoray 600W lamps, for their disinfection system.

The Santa Clara Valley Water District in San Jose, CA, required additional water supplies to maintain regional economic vitality for its growing community. 

A Kaeser EBS series screw blower is making wastewater treatment considerably more efficient and effective at the Goldsteig dairy factory in Cham in the Upper Palatinate region in Germany.

Visitors to the Japanese Gardens above the City of Los Angeles’ Donald C. Tillman Water Reclamation Plant (DCT Water Reclamation Plant) become more tranquil as they stroll along the walkways.

Increasing water scarcity, which results in higher water costs, is pushing manufacturers to reclaim and reuse their wastewater. 

Water and wastewater piping come in a variety of materials, joints, and diameters. They can meet a multitude of demands and needs for the country's infrastructure.

The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

A water purveyor was in urgent need of a chemically resistant flow instrumentation with a long life of service that allowed reliable and long-term stable dosing of the sodium hypochlorite solution.

The argument has been used that PVC pipe is delicate and can’t be subjected to any kind of loading. In EBAA's years of testing we have found that is not the case at all. PVC can take an extreme amount of strain.

In wastewater treatment, aerobic digestion enables plants to increase their capacity by injecting oxygen into the wastewater head space.

This application note explores Sequencing Batch Reactor (SBR) systems that have been installed worldwide in a variety of applications, ranging from a few gallons per minute (GPM) to thousands of GPM.

Learn how a wastewater treatment plant in eastern Switzerland relies on the targeted use of flocculants to prevent sludge washout. 

A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.

This application note explores a test which demonstrated significant improvements in Oil-in-Water monitoring of industrial wastewater in comparison to the weekly grab sample analysis method.
