Co-conditioning and dewatering of alum sludge and waste activated sludge
Water Science and Technology, 2004 Co-conditioning and dewatering behaviors of alum sludge and waste activated sludge were investigated. Two different sludges were mixed at various ratios (2:1; 1:1; 1:2; 1:4) for study. Capillary suction time (CST) and specific resistance to filtration (SRF) were utilized to assess sludge dewaterability.

Gravitational sedimentation of flocculated waste activated sludge [PDF]
Water Research, 2003 The sedimentation characteristics of flocculated wastewater sludge have not been satisfactorily explored using the non-destructive techniques, partially owing to the rather low solid content (ca. 1-2%) commonly noted in the biological sediments. This paper investigated, for the first time, the spatial-temporal gravitational settling characteristics of ...

Accelerating Phosphate Transport Across Membranes via Synergistic Chemical‐Electrochemical Carriers
Angewandte Chemie, EarlyView.A new membrane design principle based on synergistic chemical and electrochemical carriers is proposed to construct an electro‐driven carrier‐conducting membrane for high‐throughput phosphate transport. Monodispersed ferrihydrite nanoparticles embedded within the membrane act as built‐in phosphate carriers, enabling accelerated phosphate migration via ...

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy
Angewandte Chemie, EarlyView.Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

A mathematical model for the flotation of waste activated sludge
Water Science and Technology, 2002 A mathematical model that describes a batch flotation process is presented. The model employed a similar method to the hindered settling of flocculated material. This idea is based on our experimental results that the time growth curves of separated liquor zone showed a similar character to the settling curve of flocculated material, when the vertical ...
