Allowed to meet planned and unplanned downtime reliably? But surely! Facilities for the supply of drinking water and industrial water and wastewater treatment must meet not only increasing demands, but also at any time irrespective of extensions, repairs and maintenance or possible malfunctions. Here, the gases oxygen and carbon dioxide can ensure the uninterrupted operation of this important human and environmental systems. To water and wastewater treatment air summed up liquid the appropriate procedure under the name ASPAL. The core components are perfectly mobile and thus temporarily can be used due to their compact construction. For the gas supply air provides liquid mobile equipment of different sizes, compression and throughput rates. The demand determines the selection: be mobile tanks such as up to 30 t oxygen in liquid form, also a supply of steel bottle bundles is possible for very short lasting interim solutions. The service offer Integrating them into the existing system as well as the necessary calculation and subsequent optimization also includes the expert advice in the design of the temporary required equipment.
The units are then installed by experienced service staff and put into operation. Adequate oxygen supply of micro-organisms is decisive for the cleaning performance of the wastewater treatment plant examples from practice in biological wastewater treatment. Prevent the wastewater treatment plant there is this a deficiency, E.g. by peak loads, operating errors or repair and maintenance services of entry of pure oxygen through special entry systems and a temporary oxygen supply can upset”. It is similar in drinking water treatment: a constant ventilation is essential for the removal of unwanted components such as iron, manganese and ammonium compounds through chemical or biological processes. This can ensure if necessary using the Air Liquide services through the entry of pure oxygen. Important for high-quality drinking water on hardening and setting of the lime-carbonic acid equilibrium are also. For this purpose the use of carbon dioxide is, because it is cost effective and environmentally friendly. For the entry of carbon dioxide are two effective systems of Bicone mixer (suitable also for oxygen) and the two-stage nozzle available.
