Schultheis Weiher, Offenbach, ALMA NeoDAF HDED

Dissolved air flotation (ALMA NeoDAF HDED) in container design for the efficient reduction of phosphorus concentrations from the "Schultheis-Weiher" bathing water in Offenbach.

Municipality of Neuenkirchen / Naarmann private dairy, Germany, ALMA NeoDAF HDED

A dissolved air flotation plant (ALMA NeoDAF 40.000 in stainless steel) for the treatment of whey wastewater as pre-treatment for the Düsterbach municipal sewage treatment plant.

Advantages

Load-proportional dosing of operating materials: The inline dosing in our plants is controlled by a COD online measurement system that precisely adjusts the precipitants and flocculants to the wastewater load.

Non-clogging expansion valves: The air-saturated water flow is mixed in evenly through non-clogging pneumatic valves.

Patented, energy-efficient air saturation system: The Venturi effect efficiently mixes the air into the water, which reduces energy consumption.

Bubble Booster System: This patented system ensures energy-efficient micro-bubble formation and guarantees the optimum bubble size to maximize floc formation and separation of pollutants.

Removal of hydrocarbons, lipophilic substances, filterable substances, heavy metals and strong reduction of COD and BOD

Integrated process control with ALMA Vision software based on the Siemens TIA portal

Benefit from ALMAWATECH's tailor-made treatment chemicals (precipitants, flocculants and neutralizing agents) for efficient and reliable wastewater treatment
