BERMAD Waterworks

In our recent webinar “BERMAD Air Control in Sewage & Wastewater Applications”, our waterworks expert, Wes Caudle, discussed the importance of air valves in sewage & wastewater systems for efficient operation and protection from vacuum conditions and surge pressure. Our discussion covered the design, selection, and operation of air valves in sewage & wastewater systems. If you are interested in learning more, you are welcome to watch the webinar recording.

From its inception 57 years ago until today, BERMAD, a world leader in water flow management and control, continues to operate its business with a strong focus on sustainability.
The company develops and manufactures unique standout products and solutions, in terms of their quality and suitability for customers' needs, long service life and minimum cost of ownership as well as in terms of their hydraulic and energy efficiency.

In our recent webinar “BERMAD Large Hydraulic Control Valves - Specification and Selection”, our waterworks expert, Micha Baer, talked about the History and the need for Large Control Valves, discussed the Various types, Pros and Cons, Requirements and Specifications, Features and Benefits, and presented Case Studies of Large Hydraulic Control Valves Projects.

Proper valve sizing is a vital factor in water system design. Accurate sizing is critical to achieving optimal efficiency, stable operation and system/valve longevity. That said, choosing the right valves can be a complex and time-consuming task as water system designers need to take multiple factors into account. In this webinar, we learned how to use BERMAD's Sizing software.

In a recent BERMAD webinar on Smart Metering with Electromagnetic Flow Meters, Elad Orenstein, Smart Metering Product Manager talked about the benefits of using electromagnetic flow meters in collecting accurate data and making it available anywhere, anytime.

Air valves are commonly used in sewage and wastewater systems to increase the system's efficiency by evacuating large volumes of air during pipeline filling and releasing entrapped air and gas pockets during pressurized operation. Air valves provide protection from vacuum conditions by enabling large volume air intake; protecting pipelines during draining or bursts; and providing controlled air relief to reduce potential damage during water hammers or surge pressure.

A GUIDE FOR SYSTEM DESIGNERS

The presence of uncontrolled quantities of air in water systems can seriously affect their performance, causing inefficient filling and draining procedures and flow reduction, while increasing energy costs. It also disrupts the operation of some of
the system’s components.

In a recent BERMAD webinar, “How to Design & Implement a Pressure Reducing Station for Extreme Pressure Difference,” Micha Baer, our Waterworks Application Engineer, talked about the challenges in dealing with extreme high pressure in a water supply pipeline.

In a recent BERMAD webinar, “Smart Metering with Electromagnetic Flow Meters,” our Smart Metering Product Manager Elad Orenstein talked about the benefits of using electromagnetic flow meters to collect accurate data and make it available anywhere, at any time.

In a recent BERMAD webinar, “Optimal Air Valve Selection for Water Systems,” our application engineer Tal Levi presented tools to optimize the selection of air valves, parameters affecting performance, and premature kinetic closure. 

In a previous blog post, we described how as a result of rising awareness about energy savings and environment protection, water supply and distribution systems need to be more efficient and be able to operate optimally at minimum pressures. While single-chamber control valves were traditionally used in these systems due to their cost-efficiency, their functionality is limited in such low pressure conditions.

Since the turn of the last century, hydraulic control valves that utilize line pressure as the energy source for their operation have been used in water supply systems. These valves are used for specific control functions that include pressure and flow control, water level control in tanks and reservoirs, remote open and close, and more.

Water hammer, or hydraulic shock, is a major concern in bulk water supply systems. It is even more of an issue when dealing with high pressure systems where failure may have a catastrophic impact. It is caused when fluid moving through the system is forced to suddenly stop or change direction, creating a pressure wave that can create vibration and noise, damage pumps and other system components, and even collapse pipes.

What’s the connection between control valves and smooth take-offs and landings at Berlin Brandenburg Airport?

The Berlin Brandenburg Airport is a 14.7 km² airport that is situated 18 km south of Berlin, Germany, and is currently under construction. The 6.8-billion-euro project began in 2006 and includes two parallel runways, a six-floor passenger terminal, a 32-meter observation tower, and a museum and gift shop. The facility is designed to handle about 65 aircrafts, with a passenger capacity of up to 27 million per year. The airport is expected to open in autumn 2020.
