Innovations for wastewater pumping

Friday, March 2nd, 2018 von admin

Fig. 1

At the previous Ifat, Swiss company Egger presented a further development of their completely retracted Turo centrifugal impeller TA for raw sewage conveyance. To date, a large number of pumping stations that are burdened with high solid loads (such as fibrous materials, wet wipes, etc.) have been successfully equipped with them. Blockages could be eliminated or – under extreme load – reduced to a minimum.

At Ifat 2018, the company is now presenting a low-clog and 100% dry-running-safe centrifugal pump hydraulic system. A further development of the Eurodyn hydrodynamic shaft seal in conjunction with Turo Vortex hydraulics makes absolutely dry-run safe use possible. The pump hydraulics and shaft seal operate completely contact-free. In the case of wastewater pumping operations that comply with the regulations, the pump set as designed by Egger enables 4-years of maintenance-free operation.

Maintenance-in-place-solution for progressing cavity pumps

Monday, February 19th, 2018 von admin

Progressing cavity pumps from Allweiler can be delivered with an Optifix option. The pump can be disassembled in five steps, and eliminates the need to dismantle it from piping to change the rotor, stator, joints or shaft seal.

Designed to deliver superior speed and efficiency, Optifix’s easy exchange design is optimized for safe and streamlined inspections, parts removal and service operations. In wastewater treatment service, Optifix can reduce mean time to repair intervals by as much as 85 percent and boost pump service life by up to 500 percent when combined with patented Alldur stator solution.

PSG at Anuga FoodTec 2018, Cologne

Thursday, February 15th, 2018 von admin

PSG has been providing pumps for the food and beverage industry for over two decades. The PSG brands that serve this market meet the strict requirements for hygienic transfer with certifications like 3A, FDA, EC 1935/2004 and EHEDG, providing solutions that safely transfer high value fluids. The exhibition motto at this year’s show is “Resource Efficiency,” which refers to utilizing resources in a sustainable and optimized way to minimize impacts on the environment, or in other words, to deliver greater value with less input. Specifically, the PSG brands that will be on display at this year’s show include:

Hygienic rotary lobe pump with smooth housing

Wednesday, February 14th, 2018 von admin

The smooth design of the rotary lobe T.Sano series means a completely smooth housing which attracts barely any dirt or dust. This design has been specially developed for the hygiene and food industry, because not only the materials and the cleanability of the pump chamber are subject to strict requirements in the food industry, the outer contours are also taken into account. Ideally, the design of the pump housing must have no rough edges or dead spaces to make sure that no contamination can set.

Self-cleaning tank inserts for waste water tanks

Thursday, February 8th, 2018 von admin

At this year’s Ifat trade fair in Munich, KSB is presenting its ready-to-install self-cleaning Amaclean tank insert. Amaclean decreases the amount of stagnant water in the pump sump and reduces the need for maintenance and cleaning.

In combination with select impeller types featuring in the waste water pumps used, this tank insert eliminates the need for flushing valves. Amaclean’s patented design and gel-coated inner surface prevent waste and fibres contained in the waste water from depositing in and at the lower parts of the structure.

Andritz to supply irrigation pumps for Egypt

Thursday, February 8th, 2018 von admin

International technology Group Andritz has received an order from Concord for Engineering and Contracting, Cairo Egypt, to supply 17 vertical line shaft pumps, including a set of spare parts, for a pumping station providing the water supply to the Nubaria irrigation canal, located south of the city of Alexandria. Start-up is scheduled for 2018.

The pumps supplied will be individually adapted to the customer’s specifications and achieve an aggregate flow rate of 11.7 m3 per second.

Each pump achieves a head of 28 meters at a shaft power of 222 kW.

What To Consider When Selecting a Filter-Press Pump

Friday, February 2nd, 2018 von admin

Technical paper by Peter Schüten:

High-Pressure Air-Operated Double-Diaphragm (AODD) Pumps Deliver The Operational Advantages Necessary For Optimized Operation Of Chamber Filter Presses.

In many industrial processes that feature the handling of liquids, the substances that are being transferred may occur in an aqueous or “muddy” state, with the liquid portion needing to be removed. This liquid-removal stage may take place during the production process – for example, in the filtration of edible oils or yeast solutions – but it more frequently occurs at the end of a process like wastewater treatment when the waste sludge that has formed must be withdrawn. Since the disposal of such sludges is calculated based on weight and volume, their thickening and drying is particularly lucrative for the processor. During the thickening and drying process, the sludges are treated using chemicals and/or physical processes so that the waste sludge forms into flake-like solids. After adjusting the pH level to neutral or alkaline via the use of milk of lime, the subsequent dewatering process separates the water for disposal, with the remaining volume of sludge significantly reduced.

The simplest technology for this process involves collection and thickening of the sludge through the use of gravity. However, it is significantly more effective to use technical drying methods via processes such as centrifuges and evaporators, or more commonly, chamber filter presses (Fig. 1).

Systematic flow metering – instrumentation for water supply in desert region

Tuesday, January 30th, 2018 von admin

Aguas de Saltillo, the water utility company which serves the city of Saltillo in Mexico, is responsible for supplying drinking water to a population of around 850,000. To ensure a reliable supply in this arid desert city, the company relies on a water network which draws from several reservoirs with the aid of process instrumentation from Siemens. The Sitrans F M MAG 8000 electromagnetic flow meters used here are outstandingly robust, durable and reliable, as well as requiring minimal maintenance. Over a hundred of these devices have now been installed in the Aguas de Saltillo network.
