Dewatering in biological wastewater treatment: A review

However, in both cases, the flocs contain water, some of which is removed during compression, i.e. according to Deng et al. (2011), interstitial water accounts for more than 50% of the water in the flocs and is at least partly removed by mechanical dewatering (Novak, 2006). The dewatering process therefore depends on the strength of the floc ...
