Water Treatment

The demand for clean water and to this water treatment will continue to gain importance. Apart from the worldwide increasing drinking water needs, further municipal and industrial processes are also reliant on efficient solutions for water supply.

Apart from water treatment processes, dissolved air flotation is most widespread in sewage technology, because it has proven as an economic and efficient process both with municipal and industrial sewage treatment.

The dissolved air flotation (DAF) is a chemical/physical waste water treatment process where water is first pressurised and saturated with gas or air. Subsequently, the water is reduced to atmospheric pressure, whereby a corresponding gas air proportion is released in the form of finest bubbles. In the solid substances, these micro bubbles form an agglomerate which due its low density rises to the surface of the flotation tank and can be mechanically cleared up here.

On account of the requirements for water quality becoming stricter the world over, most municipalities and industries have their own wastewater treatment plants in the meantime.

Successful application solutions

Grease and other pollutions have to be separated from mechanically pre-cleaned abattoir wastewater. Considerably improved flotation effect (bubbles image) and improved pump service life. Cleaning result considerably improved due to the improved bubble image. Moreover, a clearly more compact flotate. Decreased consumption of flocculants. Energy balance significantly improved. Retrofitting already paid off after six weeks.

In the paper industry, limy deposits from the circulation water in pipes, cooling systems, heat exchanger et cetera are prevented using lime traps. Considerably reduced freshwater consumption and a sustainable improvement of the process reliability. Repair costs and maintenance of the systems significantly reduced.
In this manufacturing process, pumps are required to feed and outlet the water as well as for water treatment.

Wastewater is pumped through long wastewater transport channels for processing in the sewage plat. 20 million cubic metre of wastewater per year flow into the sewage treatment plant, which corresponds to a connected load of 400,000 population equivalents. Existing standard pumps, pressure vessels and compressors successfully replaced by tow multiphase pumps.

During crude oil production, oil-water mixtures accrue to a considerable degree. With multiphase pumps equipped flotation systems separate oil and water. The oil obtained is further processed, and the water is returned back into the drill holes. Contrary to industrial applications, multiphase pumps are made in superduplex design for reasons of resistance.

Maritime bio-fouling is the main problem for materials which are in contact with seawater. Deposits of seawater organisms affect the function of drives and other facilities on board which require uniform cooling, thus affecting safety of the ships. By means of ozone, the quality of seawater for cooling the ship engines is improved, thereby avoiding considerable repair costs as well as ensuring smooth operation of the ocean-going vessels.

When processing regenerative energy sources such as biodiesel, timber, animal meal or calorific types of waste, the inert CO2 is leached out of the synthesis gas. Using a compressor, the gas is pressed into an absorption container where it flows upward through a packed bed. This filling is sprayed from above by a multi-phase pump. Water enriched with the CO2 from the synthesis gas and then widely degassed in a desorption container.
