Wastewater now and in the future is a challenge that needs to be addressed with a long term approach. Wastewater treatment has emerged as a frontrunner, with the capability to address existing water demand-supply gap to a large extent. It plays an instrumental role in reducing the dependency on the current depleting ground water resource in the country.
The rising price of fresh water plus a range of new environmental factor and most importantly the energy cost of transporting wastewater to the treatment plant must be accounted for when planning a modern wastewater system. Grundfos India, a global leader in advanced water solutions and a trendsetter in water technology has introduced its innovative SE1 pump with an S-tube impeller to cater to the wastewater treatment processes. The Grundfos S‐tube impeller is designed to help meet all these diverse challenges.
The main and interlinked challenges which the water utility companies face today in relation to the transport of wastewater are:
Aside from stricter controls on usage, the rising cost of energy has increased the incentive to find more efficient methods of transporting wastewater. Water‐saving innovations have also created new problems. For example, more efficient toilets use less transportation fluid, thus increasing the risk of clogging farther down the line. Traditional wastewater pumps add to this clogging risk rather than solve it because of the design issues such as, leading edges on which waste material easily gets caught, bends in the pipework, cutting mechanisms and reduced free passages.
The fundamentals of the revolutionary S‐tube impeller, have actually been on pump designers’ drawing boards for decades. The volume and diversity of waste material to be transported was relatively low, and therefore details such as the water and energy usage were barely considered by utility providers. It is only in the past two decades that a variety of factors have all collided to make the S‐tube design relevant. These include: increased environmental awareness, new government legislation and directives, and the rising cost of water, energy and wastewater transport.
Integrated with motors, hydraulics and a seamless functionality, the intelligent SE1 solutions is one of the most efficient wastewater pumps. Grundfos SE range of pumps with an S-tube impeller have also been able to significantly boost energy savings in wastewater operations while simultaneously reducing the number of jamming related incidents.
