Seepex supplies energy saving package for wastewater treatment plants
Smart Air Injection ( SAI ), SEEPEX ’ s patented sludge pumping system , is delivering cost savings to wastewater treatment plants ( WWTP ) around the world . One of the many satisfied customers of the energy-efficient technology is the WWTP Hetlingen , near Hamburg , Germany , which will now save around 20-25 % of energy in thick sludge pumping alone .
Environmental and economic considerations play a decisive role when municipal water utilities are considering the purchase of new pumping technology . Worldwide , SEEPEX ’ s energy-efficient and low-maintenance SAI-system ensures that thick sludge reaches its destination at low pressure , even over distances of one kilometre .
Two conveying technologies for a customised solution
With SAI , SEEPEX , the world ’ s leading specialist in progressive cavity pumps , pump systems and digital solutions , has launched a customised system solution . It uses a combination of progressive cavity pumping and dense phase pneumatic conveying to transport highly dewatered sludge discontinuously in short plugs in a particularly energyefficient manner , unlike any other conventional conveying technology .
In principle , it ’ s just like the good old pneumatic mail . As a result , friction losses only occur along these plugs and not in the entire pipe , resulting in numerous unique advantages , such as the ability to transport up to 1 kilometre with a low-pressure pump and PN10 piping .
For municipal water utilities in the UK , the alternative to conventional processes , which has been tried and tested worldwide for years , can quickly pay for itself . More than 80 customers already benefit from this innovation , which is patented in Europe , the USA and China .
