Title: Sludge disposal - involves using water removal and fertiliser collection to develop a biomass for disposal
IPC: C02F3/32
Filed: 1991-12-19
Abstract: Recovering usable materials from sludge involves laying the sludge on flat fluid impermeable underlays after the water has been removed from it, and removing further water through a drain system. The dissolved plant fertiliser is collected as sump water and the remainder of the plant fertiliser and organic matter in the sludge is passed through vegetation which takes up a lot of water and builds up green masses which can be used as a biomass. Compressed rubbish surfaces are pref. used instead of artificial basic compression. The sludge to be removed is mixed together with structure carriers, bulk materials or plant fertilisers to improve its mechanical strength and suitability as fertiliser material. The layers of sludge are built up in a number of layers, to give a partial water extn. and form a biomass and improve its performance on laying. Water drains are located between separate sludge layers and below layers. Sump water is trickled back once or more times, as additional fertiliser to form the biomass, to the surfaces of the sludge layers, or injected within them. Additional water is sprayed over the sludge layers to increase the fertilising action. As the sludge is deposited in layers, they are covered with thin layers of compost or earth or ground stone, to dampen any emitted smell. ADVANTAGE - The method handles municipal sludge from sewage so that it can be disposed safely and without incineration or spreading of harmful and toxic matter, in an economic operation.

Inventor: KASSECKER ROLF-RUEDIGER
IPC: G01N17/00
Filed: 1992-03-31
Abstract: The properties are evaluated by (1) forming paint film with dry film thickness 10-100 microns and hardening it (2) measuring UV transmission spectrum of hardened film in wave length region 190-350 nm (3) setting transmission spectrum in relation to emission spectrum of light source which causes weathering damage to the hardened film.

Relation to emission spectrum of light source is made by comparison with starting points of transmission spectra of hardened films whose weathering behaviour in relevant emission spectrum is known. Emission spectrum of conventional light-weathering appts. is used as comparison. Emission spectrum of light source with emission curve in UV-B region is selected. Film is of clear lacquer or of top coat freed from pigments and/or fillers. Paint film is formed on support and removed from it before measurement, or formed on support transparent to UV radiation and UV transmission spectrum is determined in double irradiation measurement process, an uncoated, identical support treated in same way being used for comparison. Paint film is applied on support, dried or hardened with support at up to 240 deg.C, or cured through actinic radiation, then opt. removed from support.
