Critical Factors in Adopting Cooling Media for Central Air-Conditioning Systems in Hong Kong
There has been a dilemma about whether to adopt water-cooled or air-cooled air-conditioning systems at various times for different developments in Hong Kong, strongly influenced by the local government. Fresh water has been a scarce resource as a cooling medium; however, in recent years, the local government has advocated water-cooled air-conditioning systems, using fresh water or sea water as a ...

Influence of cavitation phenomenon on the hydraulic behavior of leaks in water distribution systems
This paper examines the hydraulic behavior of leakage from water distribution systems under condition of cavitation. For this purpose, an experimental model featuring small (i.e., a fraction of a millimeter) orifice openings was designed and built to simulate idealized cracks in defective pipes. During the tests, water was allowed to flow through the cracks at controlled pressures during ...

Why PPR has several colors: green, gray, white or other colors. What are the differences?
As it is known, there are several manufacturers worldwide, from America to Romania. Each manufacturer has their own system of colors and lines. In fact, this is a market strategy. This means that if no special materials are used in the production of PPR, the color is not very important, except for the color black. PPR as a raw material exists in several forms. It is generally called PP-R or ...

The biological safety of distribution systems following UV disinfection in rural areas in Beijing, China
In rural areas, UV disinfection has a great potential for drinking water treatment because of the ability to achieve target disinfection levels and the ease of operation and maintenance; however, UV disinfection provides no disinfection residual to the water distribution system. This study examines the biological safety of rural water distribution systems following UV disinfection. The results ...

What is a CAV constant air volume damper?
What is a CAV constant air volume damper?Constant air volume valve (CAV) is a mechanical self-operated device, also known as CAV damper, suitable for ventilation and air conditioning systems that require constant air volume. The air volume control of the constant air volume valve does not require external power. It relies on the air force in the air duct to locate the position of the control ...

SCADA monitoring maximizes pump system performance - Case Study
The system tracks pump efficiency so repairs can be anticipated with timely, accurate and reliable information. Manually managing a water system can be difficult, especially with population growth and limited resources. Saving time and money are common challenges for utilities. Water system management was an ongoing concern for the city of Eureka, Mo., located approximately 28 miles southwest of ...

6 Things You Should Know About Legionella
Just last August, about 120 people in the South Bronx were infected with Legionnaires’ Disease and 12 people died. At the time, up to 5 cooling towers in the area tested positive for Legionella, a fatal bacteria that grows in warm, damp environments and can spread once contaminated water has become aerosolized and the vapor is inhaled. In this post, we’ll be discussing where ...

Waste Heat as a benefit of VOC Destruction with a Thermal Oxidiser - Case Study
Application Although many look at the energy used to destruct VOCs as an unnecessary waste, Dickinson Legg (now Garbuio Dickinson), the world leader in the design and manufacture of Primary Tobacco Processing Plants saw it as an opportune way to supplement the heat required in their client’s tobacco refining process – in very different ways. Garbuio Dickinson chose an ERG owned ...

Drive Operational Efficiency with Water and Wastewater Digitization
Any organization with a long history is bound to resist change. Most municipal water systems have been in place for decades, and many of their processes reflect the technology of earlier periods. They may still use paper requisition forms or manually log system information into spreadsheets. Inefficient processes increase costs and are prone to human error. As water utilities deal with aging ...

Pearl river valley water supply district case study
Performance History and Discussion In-Pipe Technology implemented the first phase of a collection system Professional Services Program in 2001. Beginning in 2002, additional collection system basins were added to the services program. Currently, the treated areas include the North and South shore of the Pelahatchie Bay, the Main Harbor, and two Lagoon Waste Water Treatment Plant (WWTP) collection ...

A result-oriented, hands-on, lean-thinking leader
“When I was a kid, I would take apart every toy I got, rebuild it, then play with it—maybe a sign of an engineer-to-be,” said Jonathan Gur, who has worked in the water treatment industry for more than 30 years. “I have held management and executive positions with global companies – both in municipal waste-water treatment/potable water supply and the technology ...

Total Dynamics of Quartz–Water System at Ambient Conditions
New data on the dissolution and growth of quartz in acid, nearly neutral and slightly alkaline solutions at ambient conditions are presented. During batch dissolutions, aqueous Si-concentrations increased nonlinearly towards limit values. During parallel growth experiments, however, the high Si-concentrations corresponding to 13-fold supersaturation with respect to quartz did not decreased. To ...

Valves in Water System of Heating Air Condition
Common valves in water system of heating air condition include gate valve, globe valve and butterfly valve. Gate vale For its moderate length, rotary adjusting rod and good regulating performance, gate valve is widely utilized in large caliber pipes. Globe valve Globe valve is suitable for small caliber pipes for its long length, rotary adjusting rod and good regulating performance ...

Evaluation of chlorine decay models under transient conditions in a water distribution system
Residual chlorine concentration decreases along distribution networks because of factors such as water quality, physical properties of the pipeline, and hydraulic conditions. Hydraulic conditions are primarily governed by transient events generated by valve modulation or pumping action. We investigate the impact of transient events on the rate of chlorine decay under various flow conditions. ...
