Dewatering and treatment of this particular sludge demonstrated high dewatering capacity and reduced nutrient levels in outgoing water and sludge residue[29] as well as significantly reduced toxicity in outgoing water and bed material of reed beds measured with DR-CALUX, Umu-C assay and fish embryo toxicity test using Danio rerio[30].
Also, high dewatering levels leading to fewer wash stages reduces the chance of contamination in this highly manual operation.

At the same concentration, a higher dewatering of mince was observed when CaCl2 was used, compared with MgCl2 (p < 0.05).
The studies within this paper provide a method for determining how dead-end batch centrifugation may be used to yield high levels of dewatering (and hence contaminant removal) and also to retain high levels of intact cell recovery by controlled resuspension.
In this study, a hybrid forward osmosis nanofiltration (FO/NF) process was designed for dewatering high nutrient containing sludge and recovering draw solution with minimum energy as well as low fouling.
The use of high levels of dewatering to help aid contaminant removal might impact the yield of viable cells unless care is taken over the method of cell resuspension.
The same feed properties dictate the need for chemical pre-treatment to ensure the highest rates of dewatering and best clarity of filtrate, and correct choice of filter cloth is also crucial in these respects.
The problem is that the ethanol usage in the first step for dewatering is too high to cause high-energy consumption of ethanol recycling.
Cyclic sorption and desorption on zeolite also poses problems, such as the requirement of dewatering step and high chance of contamination (due to uninterrupted link between the bioreactor and the separation equipment).
Chamber filter presses were found to be a more energy efficient method of dewatering, producing a higher concentration biomass (w/w) at a lower energy and environmental cost as compared to centrifugation.
(2) Five stages, including dewatering, pressure hold, pressure control, high and stable yield, and depletion stages, are classified based on the in situ pressure change characteristics, such as bottom-hole flowing pressure, desorption pressure, and strata pressure (Qin et al. 2011; Li et al. 2011).
