Landia to supply Denmark town with POP-I 150 rpm flowmaker

Faxe, famous for its beer, is being fitted with the new mixers after its wastewater treatment plant’s ‘racetrack’ design became inviable.

The new flowmakers’ slow speeds are designed to avoid disturbing the required biological balance. Their light touch also contributes to their low energy consumption, according to a press release from Landia. The plant was previously using surface-brush aerators.

The company designed the flowmaker to ‘agitate, homogenise and suspend solids in demanding conditions’ and is used to mix ‘granulated sludge’.

Eight of the 5.5kW units are being installed without interruption to the wastewater treatment plant, as its tanks (79.5m in length, 22m wide and with a volume of 2,720m³) cannot be drained.

Landia’s flowmakers can be manufactured with ‘100% acid-proof material for food or chemical industry applications’.

This flowmaker has previously been installed in the York River Treatment Plant in Seaford VA. The site also boasts World Water Works’ DEMON (an acronym for Deammonification) process, which removes 70-90% nitrogen from wastewater. The site was the first in the US to use the technology, according to the company’s website.
