Various ways of waste activated sludge recycling

The recycling of waste activated sludge (WAS) formed in the process of biological purification of sewage is an urgent
ecological problem. In the present work, we consider various technological schemes for the utilization of WAS, namely:
obtaining carbon adsorbent in the framework of low-temperature carbonization of WAS; synthesis in the framework of low-
temperature sintering of WAS- glass mixtures of composite adsorbent granules consisting from carbon and porous glass;
low-temperature synthesis of foam glass from mixtures WAS-a fusible comminuted glass; synthesis of porous brick products
in water-saving mode when using WAS with high humidity; production of porous carbonized ceramics using WAS and firing
under oxygen deficiency conditions. The obtained results showed that on the basis of the developed technologies it is possible
to obtain active adsorbents for water purification from dyes, for filtration of sewage from suspensions and brick products of
various porosities with good mechanical properties.
