Egerer private brewery, Germany

The project:


Preclarification of brewery wastewater from the Egerer private brewery before introduction into the community wastewater network. Clarification should take place in the existing round tank with a 12m diameter and a depth of max. 6.5m.


Executing company:

Privatbrauerei und Mineralbrunnenvertrieb H. Egerer, Großkölnnbach


Tsurumi consultants:

Mr. Carsten Bode (Product Manager Aeration Systems)

Mr. Christian Kulik (External sales force Bavaria)


The problem:


Production wastewater leaving the brewery must be enriched with oxygen before it can be introduced into the local wastewater network.

The load factor of the wastewater is inspected by the community to calculate wastewater charges. A reduction in organic burden in the process wastewater would therefore lead to a corresponding reduction in wastewater charges.


The solution:

A 150TRN440 submersible aeratior with 40 kW motor power was installed centrally in a standalone installation in the existing round tank.

The submersible aeratior completely ventilates and mixes the round tank. The self-priming design of the assembly makes a compressor superfluous.


Depending on the water level, the aeration is time-controlled and the submersible ventilator will only be used temporarily. A foam monitor is also installed in the tank.


Electrical monitoring is carried out using a differential current relay (GFCI). Instead of being operated in a direct start, the ventilator is operated with a soft starter. This "slow start" protects the unit and entirely rules out any movement of the assembly in the tank due to the unavoidable jerk at start-up.

Aplinkoje, kur yra braižančių dalelių ir korozinių medžiagų, tam tikri komponentai natūraliai dėvisi greičiau. Eksploatuojant pirmiau minėtomis sąlygomis, sparčiau dėvisi sparnuotė, maišytuvas, siurbimo plokštė, veleno sandariklis, alyvos žiedas, mechaninis sandariklis, siurblio korpusas, koštuvas, variklio korpusas ir išleidimo mova. Atsižvelgiant į darbines sąlygas, šių dalių eksploatacija gali gerokai sutrumpėti ir nesiekti įstatymais nustatyto garantijos laikotarpio.
Tokiu atveju reikia atidžiai perskaityti mūsų bendrąsias sąlygas ir nuostatus, kuriuos, gavę atskirą užklausą, galime išsiųsti paštu.
