Energy and phosphorus recovery from black water.
Source-separated black water (BW) (toilet water) containing 38% of the organic material and 68% of the phosphorus in the total household waste (water) stream including kitchen waste, is a potential source for energy and phosphorus recovery. The energy recovered, in the form of electricity and heat, is more than sufficient for anaerobic treatment, nitrogen removal and phosphorus recovery. The ph...
متن کاملComparison of phosphorus recovery from incineration and gasification sewage sludge ash.
Incineration of sewage sludge is a common practice in many western countries. Gasification is an attractive option because of its high energy efficiency and flexibility in the usage of the produced gas. However, they both unavoidably produce sewage sludge ashes, a material that is rich in phosphorus, but which is commonly landfilled or used in construction materials. With current uncertainty in...
متن کاملHybrid membrane bioreactor for water recycling and phosphorus recovery.
This paper deals with the performance of hybrid membrane bioreactor (MBR) combining the precoagulation/sedimentation and membrane bioreactor. The hybrid MBR not only produces the treated water with excellent permeate quality but also shows much lower membrane fouling than the conventional MBR. It may come from its extremely low F/M ratio to maintain the low viscosity even in the high MLSS conce...
متن کاملPhosphorus Recovery from Animal Manures using Optimized Struvite Precipitation
The over-application of phosphorus, as manure by animal feeding operations, is a threat to surface water quality. Concentration of animal feeding operations and over application of manures to cropland has lead to a build-up of phosphorus on many farms (Greaves et al., 1999). Relative to crop needs, manure slurries contain higher levels of phosphorus than nitrogen. When manure is applied to meet...
متن کاملPhosphorus Recovery – Experiences from European Countries
The interest in recovery and reuse by sludge fractionation has increased in recent years, largely due to environmental and political considerations. This article is a survey of the status concerning phosphorus recovery, looking into national policies and experiences in different European countries to find different factors influencing the development of phosphorus recovery. The ambivalence of s...
