“…Estimation based on these results would predict that the same situation of dewatering could be reached in 470 hours in columns without electricity although the evaporation could of course accelerate the reduction of water. Typically electro-osmotic dewatering of clay soils is of the order of 1-4 orders of magnitude faster than hydraulic dewatering [5]. On average, 400 ml of water was collected from plastic tubes with electric treatment, half of which when electricity had been on for 13 hours (See Figure 2).…”

“…Electrokinetic geosynthetics (EKG) have been identified as a platform technology, which combines a wide variety of materials, functions and processes to perform such diverse functions as dewatering, strengthening and conditioning in materials such as soils, sludges, slurries, tailings and compost [3]. Dewatering of sewage sludge using EKG together with a belt press succeeded to raise the dry solids content of the dewatered cake from 19 % to > 30 %, which will make the handling of sludge considerably cheaper [4,5]. Also, the EKG application offers potential to dewater sewage lagoons in situ [6].…”

“…W konsekwencji niewiele zmniejszona jest objętość powstających osadów co tym samym wpływa na wysoki koszt ich transportu i składowania. W procesie oczyszczania ścieków, odwadnianie osadów jest jednym z najtrudniejszych zadań, stąd opracowano i udokumentowano wiele technik ich odwadniania [Glendinning et al, 2007]. Wśród nich można wymienić proces odwadniania mechanicznego, który jest powszechnie stosowany m.in.…”

“…w komorze (1) następuje upust nadciśnienia (3). W ostatnim etapie, następuje zamknięcie dopływu osadu zaworem (6) dopły-wającego do komory filtracyjnej (7). Z komory filtracyjnej (7) pobierana jest tkania filtracyjna wraz z odwodnionym osadem w celu wykonania oznaczeń.…”

“…Sua proposta de alteração da estrutura física do leito de secagem convencional resultou num aumento da taxa de drenagem e melhoria da qualidade do drenado, conforme foi também confirmado por outros autores (FONTANA, 2004;BARROSO, 2007;FONTANA et al, 2007). Figura 22 -Ilustração dos leitos de secagem modificados por mistura e aeração à esquerda e ao centro (YAMAOKA; HATA, 2003) e pela utilização de forças eletrocinéticas à direita (GLENDINNING et al, 2007) …”
