Bottom Sedimentation Prevention Solution to Maximize Filtration Efficiency in Wine Clarification

Project Overview

Premium wine manufacturer I operates a 2-ton filtration tank to control wine turbidity and remove impurities.
In this process, perlite and bentonite are added to adsorb impurities. However, these powders quickly settled at the bottom of the tank, causing a sharp decrease in filtration efficiency.
To overcome the limitations of the narrow and tall tank structure and effectively keep the sediment suspended, Company I introduced SEDNA ENG’s bottom-mounted magnetic mixer.

Challenges

1. Rapid Sedimentation of Filter Aids

Perlite and bentonite have a higher specific gravity than wine, causing them to settle at the bottom of the tank within a short time. Once settled, their adsorption surface area was reduced, making it difficult to achieve the expected filtration effect and resulting in lower wine quality.

2. Narrow and Tall Tank Geometry

For space efficiency, the filtration tank had a small diameter and a tall structure. This geometry required strong mixing power to lift the settled particles from the bottom and circulate them throughout the tank.

3. Difficulty in Top Installation and Maintenance

Installing an agitator with a long shaft at the top of the narrow tank would make maintenance and cleaning difficult and unsafe, requiring the tank cover to be opened or the shaft to be removed. Therefore, it was essential to keep the top space clear.

SEDNA Solution

1. Bottom-Mounted SDM Magnetic Mixer

SEDNA ENG selected the bottom-mounted SDM magnetic mixer as the optimal solution to generate mixing force directly at the lowest part of the tank, where sedimentation occurs. This was the most effective position for re-suspending settled particles.

2. Powerful Upward Flow Generation

Considering the narrow and tall tank geometry, SEDNA ENG selected an impeller that generates strong upward flow. This continuously lifted perlite and bentonite from the tank bottom to the upper section, maintaining a uniform suspension.

3. Top Space Secured for Easy Maintenance

By moving the drive unit to the bottom of the tank, the complex top-mounted structure was eliminated. This allowed the tank cover to be opened freely, significantly improving the convenience and safety of maintenance and internal cleaning.

PROBLEM

SOLUTION

01

Maximized
Filtration Efficiency

Perlite and bentonite were evenly dispersed throughout the wine without settling, maximizing adsorption efficiency and enabling the production of clearer, higher-quality wine.

02

Effective Sediment
Re-suspension

Strong mixing force applied directly from the bottom completely re-suspended settled particles, even in a narrow and tall tank.

03

Improved Operational
Convenience

Securing open top space improved maintenance convenience for operators and reduced the risk of safety accidents.
