The textile industry in Bahrain dates to ancient times. In the time of Alexander the Great, the country was as known as a producer of clothes seen throughout Arabia and the Indian subcontinent. Modern day Bahrain maintains its strong tradition in textile manufacture.
There’s a new wastewater pump in town. Launched at WEFTEC 2016, the Flygt Concerter integrates control panel intelligence inside the pump. Lisa Riles, North America Flygt Product Manager with Xylem, sat down with Water Online Radio at the show to discuss how the new pump works.
A global scarcity of resources is a compelling reason for businesses and people to use raw materials more responsibly. Modern municipal water supply concepts must therefore not only consider such aspects as the structural development of the region and the population’s quality of life, but must also integrate the sustainable use of water in their policy planning.
As some of you may have heard, LuminUltra has partnered with Microbe Detectives to offer DNA testing services to the drinking water and wastewater industries. So “Who’s on First?” (pun intended); simply put, the partnership’s combined technologies tell you who is in a given water or wastewater sample, and how much is in that sample.
You may have heard about the tragedy in Flint, Michigan — but to keep everyone on the same page the water in that system has turned toxic.
While most of the country was seeing red, white, and blue this past Fourth of July, many Florida residents were seeing green.
More than 6,800 cubic yards of structural concrete are being used in the construction of a new Trickling Filter and Trickling Filter Pump Station in Bismarck, North Dakota. These structures are being built well below the area’s water table, and the more than 6,800 cubic yards of concrete will protect them against the effects of Mother Nature.
The water treatment plant at the client’s site was designed not only to meet low level discharge requirements for overall environmental compliance but also to meet the regional discharge levels of the Great Lakes Restoration Initiative (GLRI). This initiative included strict discharge limits of mercury at 1.3 parts per trillion.
Energy efficiency is more crucial to the water industry than ever before. With ever-increasing costs and regulatory pressure, plant operators are constantly looking for ways to strategically manage energy use. Tom Kemme, the global product manager at Magnetrol, took the time to walk Water Online through the critical areas of energy use at a treatment plant, the advantages of measuring heat transfer over pressure drop, and how proper management can impact a plant’s bottom line.
When I look back at 2016 one of the most significant trends I observed was the growing acceptance of ORP measurements, especially for monitoring disinfection. With one caveat, the ORP value measured in a solution provides an unambiguous measure of the disinfection efficacy.
The U.S. EPA’s latest roster of concerning drinking water contaminants offers clues into what may be threatening consumers and the regulations that come next.
A U.S. EPA “call to action” for improving drinking water seems to lay the groundwork for the new president to address public health.
Polyfluoroalkyl and perfluoroalkyl substances like PFOA and PFOS have emerged as the contaminants of greatest concern for many consumers. While the U.S. EPA has issued a health advisory with limits on the chemicals, some affected communities wonder if their restrictions go far enough. So, what is an acceptable amount of PFOA in your drinking water?
With winter snow comes the inevitable introduction of a water source foe: road salt. With potential hazards posed to consumers and the environment, it’s up to treatment plants and utilities to do something about it.
Many drinking water utilities have made or are considering the switch from chlorine to chloramine to avoid regulated disinfection byproducts. However, the Water Research Foundation warns that chloramination presents its own set of problems.
There have been many publications lately that claim universal appeal of the ORP sensors and their applicability across the board. This concerns me, because the authors sometimes forget to mention some well-known practical limitations of the method, let alone the realities of water treatment applications potentially influencing the sensor performance.
When Flint Michigan discontinued purchasing water from the Detroit Water Authority and began using the Flint River as their raw water source they unfortunately did not consider the potential impact on lead and copper corrosion and the impact on the public.
When is the last time you took a moment to stop, and smell your water? A continuous supply of clean and safe drinking water is something that most people take for granted. We rarely go to the tap doubting that the water will be clean and safe. Recently, the general population and water supply professionals have become concerned about the safety and protection of our drinking water supplies.
For water treatment operators and utility officials, the summer months don’t just mean sunshine, pool parties, and barbecues. The season also brings the peak time for algal blooms, the toxic clouds formed in surface water thanks to increased nutrient contamination and rising temperatures. With rising instances of toxic algae around the country and increased regulations for eliminating it, utilities have had to keep pace.
The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?
We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.
Chemical, petrochemical, and oil-reﬁning plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution. These external demands are matched by equally compelling internal pressures to address product puriﬁcation needs, ﬁnd alternatives to utilizing costly fresh water in production processes, reduce the carbon footprint, and operate efficiently and proﬁtably.
