MixLine MX7300 – Solution preparation system for flocculants

MixLine 7300 is a full-automatic three-chambered solution preparation system for preparation of liquid polyelectrolyte/salt solutions from dry and liquid materials. The solution preparation system is completely mounted and DIN/VDE certified.

Mode of operation: stream principle

According to this principle MixLine 7300 prepares the chemical solution in a tank which is devided in three chambers. Moistening, dissolving, repining and withdrawal (dosing) occur in uninterrupted, continued process.

After the dissolving of the dry material or liquid concentrate the mixed solution streams between two walls from the first in the second chamber – the repining chamber. In the second chamber the solution ripens and is being replaced from the repining chamber in the third chamber – the withdrawal chamber.

During the replacing process in the boundary layers the unripe solution can admix with the ripe solution marginally. The mixing is unattended small, but it must be account in processes that need absolutely ripe solutions.


Capacity: 500 - 10,000 l/h

The solution preparation system MixLine 7300 is composed of:

  • 3-Chamber-Tank made from PPH with dissolving, repining and dosing chamber
