feijenoord won the contract to remove the rust from the historic iron bridge "melkbrug" in haarlem, the netherlands, to enable the damage to be analysed for the subsequent restoration work. additionally, the up to 3 cm thick layers of rust and 3 mm epoxy had to be removed from the bridge which was built in 1886. feijenoord required a comparison between falch ultrahigh water pressure technology and sandblasting - and then decided on the falch-process, since sandblasting would have taken four times longer and been much more expensive. it took only three weeks to completely remove the rust from the 600 m² surface of the bridge. the work was carried out with the 2500-bar system falch trail jet 100, and thanks to the pointspeed 30 nozzle around 5.5 m² of surface per hour could be processed, surfaces that were in part small and difficult to spray. feijenoord managing director nico burggraaf was impressed: "for this contract we hired the falch trail jet 100 and could complete the contract quickly. what impressed me too was the fast service we received from falch when we had queries or minor technical difficulties!"
