For wastewater treatment plants, energy can account for as much as 75% of the overall operation costs of the facility. Aeration systems are the largest energy user in wastewater treatment plants (more than 60% of the total electricity cost), so improvements in efficiency can significantly reduce energy costs
Up to 75% of your compressed air costs will be spent on energy, so state-of-the-art aeration equipment can make the difference, not only to reduce your carbon footprint, but by substantially lowering life cycle costs. Choosing the right technology is crucial. The benefits of taking the time to learn about the range and choice of products from positive displacement blowers, screw blowers, air blowers, or turbo blowers, are immeasurable.
The spectrum and process complexity in theenvironmental industry make it indispensable to choosea well-established, knowledgeable supplier for everyapplication. Thanks to its wide range of technologies, itsbrands’ excellent reputation and its outstanding globalteam of application experts, Robuschi can provide themost suitable solution that combines superior efficiency,small footprint, minimum maintenance, operating costs,long service life and low noise emission. There arepopular control choices for an output blower systemand there are custom solutions. The main thing to do isspeak to an expert about your particular application andits requirements.
The initial investment in wastewater treatmentequipment constitutes only one of the key elements toconsider when choosing a solution. In fact, if we look atthe total cost of ownership, we are better able to assessthe cost competitiveness of each area of spending ie.capital investment, installation, operation and ongoingmaintenance costs. We provide solutions that look atkeeping to a minimum all of these components: energyconsumption, installation and set-up, service andmaintenance.
Excellence in applications is achieved thanks to aclose cooperation with our application engineers.Robuschi offers the experience and know-how gainedover of many decades as one of the industry leadingsuppliers and partners. Domestic sewage treatmentideally provides conversion processes that can turn thedischarge product into a useful byproduct, such as CHPpower, farming or even animal feed.
Choosing the best solution for sewage treatmentsystems that meet the regulations for residentialconditions as well as protecting the environment isessential. There are rainwater, drainage, and pollutantsconditions that vary.
Robuschi is able to offer a wide portfolio with varioustechnologies targeting the most efficient operationpossible, to accommodate the needs of all applicationsand their constraints. In addition to that, we providea wide range of supporting technologies such asfrequency converters, human machine interfaces andinteractive web-based communications tools to keepenergy cost down and optimise process flows.
With its market leading brands and products, Robuschi is in a unique position in the wastewater treatment sector.This is the result of a long and sustainable history of customers’ partnerships built through optimised, tailoredand high quality solutions whose reliability and performances have stood the test of time. From our engineeringexcellence to our management skills, we have the solutions to any waste water treatment plant or sewagetreatment plant application – from the initial install to providing parts and ongoing service.
In the primary sedimentation stage, sewage flows through large tanks.These tanks are used to settle sludge while the grease and oil rises to the surface and is skimmed off.Primary settling tanks are usually equipped with mechanically-driven scrapers that drive the collected sludgecontinually towards a hopper in the base of the tank where it is pumped to treatment facilities using blowers orsimilar technologies. As a result biological materials remain on the surface and the heavy components (mainlysand) are isolated.
The aeration tanks in wastewater treatment plants are activated with oxygen by using compressed air. A thoroughmixing of the sludge with oxygen increases the gas yield and reduces its retention time in the tank. Even betterresults are achieved with warm compressed air. Blower technologies can be found invarious types of wastewatertreatment plants, including aerobic activated sludge systems, SBR, nitrificationdenitrification in a single basin and MBR.
Using slurry pumps, tough, abrasive, viscous liquids and particles in suspension can be transferred from one tank toanother of the wastewater treatment plant.
Air is used to expand the filter bed, breaking up compacted material. Clean backwash water is pumped in,suspending the loose material from where the particles are lifted through and carried away.
Removing and reintroducing the activated sludge to and from the wastewater treatment process. Loading &unloading from tankers and other transport methods. The activated sludge is the main product of wastewatertreatment and needs to be removed from the facility on a regular basis, however some product maybe requiredto remain on site for reintroduction into the process in times of high inlet flow and long periods of wet weatherto ensure the efficiency and operating life of the plant. Once removed from site the activated was once just takento landfill but is now used in various applications such as CHP power, farming and animal feed. Depending on theconveying process the operating pressure is normally higher at around 1-2 bar.
