According to World Economic Forum 2017, a water crisis is evaluated as one of the highest risks to the world and with the largest impact.
As populations grow, pressures mount and finding a more sustainable relationship between water and energy supplies become critical in less than two decades.
Today, close to one third of the world’s population is estimated to live in water stressed and scarcity areas and by 2040, almost 20% of all countries are anticipated to experience extremely high water stress.
Yet, water and energy loss in the water sector are extremely high. In fact, the average amount of water wasted by waterworks is 40% worldwide and 26% in Europe – due to errors, leakages, and water pressure.
At the same time, 4% of global electricity is consumed by the water industry – a figure that is expected to double by 2040 – and water accounts for up to half of a municipality’s total energy bill.
According to the UN, 1/3 of the world’s population will live in water stressed areas in 2025.
In less than two decades, demands will rise due to growing populations, urbanization, and a larger middle class.
Danfoss pressure sensors and variable speed drives are a key component for reducing water and energy loss throughout the whole water cycle.
Experiences from 112 systems in 10 different countries show that better pressure control reduces non-revenue water and unnecessary energy consumption significantly.
In average, improved pressure management leads to 38% reduction in pressure and 53% less new breaks. Among other benefits, the energy consumption is reduced by 20-40% and the typical water leakage reduction is 38%. Moreover, the improvements result in extended asset lifetime and fewer network related complaints.
Danfoss KPI pressure switches are used for regulating, monitoring and alarm systems in industrial applications. The KP series are suitable for plant in connection with liquid and gaseous media.
Maximum energy efficiency for both water /wastewater and Industrial pump/fan applications
SWITZERLAND: The Wehrliau pumping station in Bern delivers up to 1.20 M liters of drinking water hourly. iC7 drives play a key role in ensuring reliable supply.
In early 2023, the Warren County Utility District (WCUD) in middle Tennessee was faced with a dilemma. The water tank in their Short Mountain (SM) pressure zone required cleaning and repairs as part of federal compliance regulations, but with only one tank in the pressure zone, as is the case with many rural municipalities, they had few options to maintain water service to customers while the tank was out of service during the washout process and while repairs were completed. WCUD maintains a 4.0 MGD Water Treatment Plant, six storage tanks, four remote pump stations, into four pressure zones with approximately 650 miles of mains to serve 9,000 customers in rural portions of Warren and five adjacent counties.
Recipes for cheese are thousands of years old, passed down through generations and crossing continents —like the Swiss cheese recipes used by Shep Ysselstein, owner and “grand fromage” of Gunn’s Hill Cheese in Woodstock, Ontario, Canada.
Danfoss PAHT 25 pumps help to increase profitability and reduce NOx emission of a combustion turbine installed in Kingsbury, California.
Over the past decade, the use of Sea Water Reverse Osmosis (SWRO) for desalination has taken off. With proven efficiency rates up to 92% and energy savings of up to 65% compared to traditional solutions, the opportunities of SWRO technologies deserve further exploration.
For the mechanical systems that manage the indoor environment in this desert city, consistency and simplicity are desirable traits. Owners of casino hotels and restaurants that operate around-the-clock require HVAC equipment that is reliable and easy to operate and maintain.
