Task

ALMAWATECH has successfully built and commissioned a flotation system for an ice cream manufacturer in northern Germany. The manufacturer produces a wide range of ice cream specialties, including ice cream cakes, sandwich ice cream, spaghetti ice cream and stick ice cream, which are sold under various private labels.

A special feature of the installed system is the COD-proportional dosing of the precipitants, which not only helps to optimize the use of operating resources, but also sustainably reduces the company's operating costs.

Solution & implementation

In order to reliably achieve the desired target values, the ALMA NeoDAF HDED 20.000 in stainless steel design was installed. This flotation system is equipped with an automatic dosing and preparation station (ALMA FLOC AC) for the flocculant, which ensures precise and efficient wastewater treatment.

Advantages of the ALMA NeoDAF HDED

Air saturation valves as diaphragm valves

Instead of the often problematic needle valves, the system uses pneumatically controlled diaphragm valves. These ensure trouble-free operation and guarantee an even air supply, which prevents blockages.

Aerophilic flake formation

The dosing of precipitants and flocculants takes place in closed pipe sections using an inline system. This allows air-saturated water to be mixed directly into the flocculation process, resulting in the formation of sludge flocs with excellent buoyancy properties.

Separation of large air bubbles

The patented ALMA Bubble-Booster System removes large air bubbles before they are fed into the flotation cell. This ensures a uniform flotate sludge carpet.

Sludge removal using the counterflow method

Both the flotate sludge and the sediment removal take place in counterflow, which enables the formation of a targeted gradient in the flotation cell. This improves the efficiency of sludge separation and significantly reduces re-dissolution effects.

Thank you

With the successful commissioning of the flotation plant, ALMAWATECH has once again shown that innovative solutions and efficient processes go hand in hand. Special thanks go to everyone involved in the project for their excellent cooperation and tireless efforts. Thanks to their commitment, the project was completed on time and to the highest quality standards. We look forward to further successful projects!
