Noardling B.V. products

In the field of surface aeration Landustrie has a long history and broad experience. Landustrie designs, manufactures, supplies, installs and maintains many types of aeration systems, with either surface aerators, aeration rotors, diffusers and Landox flow boosters. Since the introduction of our own full-scale aeration test tank and the availibility of substantial process know-how, Landustrie is a leading player in aeration technology. In our test rig the characteristics of our Landy aerators are constantly researched. With these test facilities an optimal aeration selection can be realised.

The efficiencies that can be obtained with low speed aerators depend on a number of factors. One important factor is the geometry of the basin in which the aerator will be installed. The Landy aerator can be installed in either a fixed or a floating arrangement. Regarding the geometry of the basins the options are virtually unlimited: square or rectangular tanks, round tanks, shallow or deep tanks, oxidation ditches, MBR- and SBR systems, lagoons, ponds, mixing or buffer tanks.

For simple and efficient aeration in municipal and industrial wastewater treatment plants Landustrie supplies two standard aeration rotors: Landy 700 and Landy 1000 resp. with aeration capacities of 54 kgO 2/h and 85 kgO2/h with maximum rotor lengths of 9 m. At special request of our clients these rotors can be supplied with other dimensions as well. Also brush aerators with floating construction are optional. Aeration capacities can be effected by variation of rotational speed or immersion depth.
