Equalization basin

The correct choice of agitator for equalization basin

For mixing sludge in Equalization basin, etc., we recommend 2 different solutions: Medium Flowmakers with relatively low rotation speed and propeller diameter of 750 – 900 mm or fast mixers with a propeller diameter of 380-440 mm.

Both solutions distinguish themselves with great effectiveness in relation to energy consumption. The choice should be made on the basis of parameters such as media, tank design, mode of operation, etc. Our consultants are happy to provide advice during the decision-making process.

Brackets

There is a wide variety of mounting brackets for both types. Made of either acid-proof, stainless, or hot-galvanized steel, the brackets are designed for years of daily operation and manufactured to facilitate the day-to-day operation, as well as all servicing of the mixers.

Equalization basin with a restricted size with at least 1 m water depth

Lind Jensen MRPG Medium Flowmaker is a submersible agitator designed for occasional mixing where there is low water depth.

- Highly suitable for mixing in Equalization basin and at inlet grates
- Strong planetary gear
- Mechanical seals in an oil bath, leakage sensor and bimetallic sensors
- Roller bearings on the drive shaft

Can be supplied at 60 Hz and ATEX approved.

Equalization basin where the water depth is usually less than 1 m

Lind Jensen has developed two fast MDDR and OMDR mixers for use in places with low water depth. Both units deliver a concentrated long range mixer jet and can also be applied in larger Equalization basin or in tanks where there is less need for a homogenisation of the media.

Both types are made 100% of acid-proof steel and are therefore also ideal for mixing aggressive media, for example, where there are high or low pH-values in the media.
