Climate change and environmental saving necessities: pressure independence in water systems
Climate change and increasing population growth is having a big effect on the availability of water and therefore distribution to consumers. Lord Bevan recently called for the reduction of 40 litres of water per day per household. HL2024 can achieve this, as well as reducing energy and CO2 emissions.
Pressure independence for water companies
Pressure independence in the water system is a way to limit the use of water and pumping energy. What exactly is pressure independence and why is it so important? Ing. Eric van der Blom from Cenergist explains: “Normally, when the pressure on a connection or tap increases, the flow rate will increase as well. Consequently, the consumer uses more water. A higher flow rate in the distribution system causes a higher pressure loss and less flow further in the system.
To have enough flow and pressure at the end of the distribution system, the water company can increase the pressure at the pumping station, but this will increase the use of water at the beginning and the pressure loss further in the system. To avoid all of this, the unique pressure-independent flow controller HL2024 equalises the flow rate during both increasing and decreasing dynamic pressure. The pressure increase in the distribution system therefore has no influence on the maximum flow rate to the households.”
