KSB Aktiengesellschaft
Leading international manufacturer of pumps, fittings and related systems – improve the profitability of biogas plants with KSB
The slow-speed, submersible motor agitators in KSB Aktiengesellschaft’s Amaprop product range have proven their worth over many years in waste water treatment and also find application in biogas plants. Their key advantage lies in the fact that they consume considerably less energy than high-speed units with small propellers.
Rather than being wall-mounted, the Amaprop is positioned further towards the centre of the pit, ensuring that fresh substrate is quickly stirred into the fermentation medium. The thrust applied at this point reduces the “tea cup effect”, which results in problematic deposits in the centre of the pit. Furthermore, the central positioning of the Amaprop produces energy-efficient, cyclic flow, and prevents floating layers and sedimentation. Gas production levels are noticeably higher with this configuration.
In order to ideally combine the advantages of the Amaprop 2500 with the flexibility offered by classic, high-speed submersible motor agitators, KSB has now developed an agitator with a pro peller diameter of 1,000 mm which is specifically tailored to the needs of biogas plants and which is the result of numerous trials and positive experiences gathered over the past few years.
As a result of its hydraulic specifications, the Amaprop 1000 agitator stands out from the crowd with its outstanding mixing ability, particularly in the case of critical flow, and its extremely low energy consumption levels. Furthermore, its flexible configuration allows the angle and height of the propeller to be adjusted during operation. This makes it suitable for universal application as a supplementary agitator, scum disperser and flow accelerator in combination with the Amaprop 2500 or as a stand-alone unit.
Thanks to its robust design, maintenance is first recommended after 16,000 hours of operation.
The Halle/Saale site is the company’s centre of expertise for water and waste water. The factory there currently employs around 450 workers.
