Abstract
This paper presents the results of experimental work of dewatering by pressure filter using geotextile, aluminium sulphate and nanoparticles. In the present day, industries produce a lot of sludge for which open dumping is done, this causes several water borne diseases, bad odour, attraction of flies and land degradation. Sludge is the main cause for the former problems mentioned. In order to tackle these problems, dewatering of sludge was done by applying pressure and using geotextile, aluminium sulphate (as a sludge conditioning material), of dosages 550 mg/l, 600mg/l, 650mg/l, nanoparticles (as a sludge conditioning material), of dosages 50mg/l, 60mg/l, 70mg/l. In this paper comparison is made, of filtrate by using just geotextile, aluminium sulphate (6000mg/l) plus geotextile and nanoparticles (50mg/l) plus geotextile. Results show that chemical characteristics such as TSS, TVS, TS, COD, BOD, SO4 has been reduced to 89.8%, 86.16%, 80.5%, 97.7%, 97.99%, 82.12% respectively with aluminium sulphate and 92.4%, 87.5%, 81.4%, 97.8%, 98.06%, 98.06%, 86.25% respectively with nanoparticles, so the filtrate can be recycled and filter cake obtained after dewatering was tested for NPK, therefore it can be used as a fertilizer, thus proving zero waste conditioning.

On pp. 306-307, after noting that Marggraf had noticed that potash caused alum to crystallize from a solution of alumina and sulfuric acid, Bergman adds "Notatuquoquedignumest, quod hoc cristallisation is obstaculumal calivolatilia equetollatur, non vero alkali minerali et calce." (It is significant as well that by [use of] the volatile alkali [i.e., ammonia] this obstacle to crystallization is similarly removed, but not [in the cases of] mineral alkali [i.e., sodium carbonate] and lime.)
