10. Take a look at why you need so much of this life-giving liquid: It assists the digestion, absorption and elimination of the food you eat It assists the excretion of waste from your bowel and kidneys It regulates your body temperature 24/7 It lubricates your joints and membranes Bloo...
Anaerobic Digestion of Yard Waste and Biogas Purification by Removal of Hydrogen Sulfide Lignocellulosic biomass feedstocks, in particular yard waste, are highly desired for anaerobic digestion as they are widely available and tipping fees are commonly associated with disposal. The high concentration of ...
The method, the assembly and the filtering device can be used in connection with biological process systems, in which the removal of sand, sludge, fibers and alike from partial volumes of the process fluid is necessary before additional filtration and subsequent sample analysis.Peter Frode Pind...

Ir involved at a laboratory scale, several liquefaction digesters, each of them treating one type of waste, coupled to a central methane fixed-film reactor The influence of pH, loan and hydraulic retention time on the process performances was studied at 35 degrees C On average, except for ...
A closed water recycling system produces portable drinking water from total domestic waste-water, including household sewage. A microprocessor monitors the operation of the system and automatically back-flushes the ultra-filter assembly, regenerates the ion exchange bed when the monitored variables indicat...
The optimum pretreatment temperature and pretreatment time for the upgrading of anaerobic digestion of WAS were 170°C and 60 minutes, respectively. At this pretreatment condition, the COD removal and the gas production were markedly increased. At the digester with retention time from 5 to 10 days...
Recently, XAD resin fractionation has also been applied to study the removal trend of organics during anaerobic digestion; accordingly, detailed information on the hydrophobic/hydrophilic polarity distribution of organic waste before and after digestion, as well as which part of the organic material was...
Therefore, the objective of this study is to evaluate the effect of substrate concentration and initial pH using two inocula (i.e., anaerobic granular sludge and waste activated sludge), during mesophilic batch anaerobic digestion of a DAF slurry. 2. Materials and methods 2.1. Source of ...
