A novel microwave treatment of sewage sludge was developed as part of the ongoing studies for enhancing the recovery of phosphorus from municipal wastes. The microwave treatment provided a rapid and efficient process to release phosphate from sewage sludge. By using the microwave treatment for only 5 min, up to 76% of the total phosphate in the sludge could be released into the solution. No che...

Autothermal thermophilic aerobic digestion (ATAD) is a promising process for sewage sludge stabilization. Batch experiments were conducted on sewage sludge collected from a municipal wastewater treatment plant in Shanghai, China, to evaluate the effectiveness of the ATAD system by determining changes in volatile suspended solids (VSSs) and to study its microbial diversity by denaturing gradient...

The article presents test results on the changes occurring in sewage sludge during the process of its storage. Tests were conducted on mechanically dehydrated sewage sludge derived from large municipal sewage treatment plants equipped with biological sewage treatment systems. In testing presented in the paper the focus was on the basic fuel properties of sewage sludge: moisture content, heat of...

Carbonization is a newly developed process that converts sewage sludge to biocoal, a type of solid biomass that can partially substitute for coal during power generation. This study presents an assessment of the environmental effects of various sewage sludge treatment processes, including carbonization, direct landfills, co-incineration with municipal solid waste, and mono-incineration in Taiwa...

The type strain SUR2 of the novel species Chryseobacterium limigenitum was isolated from a dehydrated sludge of the municipal sewage treatment plant in Dogoše near Maribor in Slovenia. The draft genome, with 60 contigs, 4,697,725bp, 34.4% of G+C content, was obtained using the Illumina HiSeq 2500-1 platform. Joint Genome Institute Microbial Genome Annotation Pipeline (MGAP v.4) has identified 4...

The combined process of A 2 /O oxidation ditch, high efficiency sedimentation tank and denitrification deep bed filter was adopted in Sewage Treatment Plant Hefei City to treat municipal domestic sewage. effluent quality could meet the discharge limit major water pollutants urban sewage treatment plants industrial industries Chaohu Lake Basin (DB34/2710-2016). In addition parameters design oper...

Abstract The decomposition of diclofenac (DCF) in sewage sludge from municipal wastewater treatment plant was investigated. It found that adsorption DCF on is about 40%. Compared to previous studies, where the degradation yield aqueous solution 100%, those experiments at dose up 5 kGy, only 50% initial concentration 50 mg L −1 decomposed sediment and over sediment. were carried out using both g...

In Sweden, municipal sewage sludge are not applied as nutrient supply on agricultural land used for crops for human consumption, due to a resistance among consumer, farmers associations and leading producers and grocery distributors. Thus, a nationwide initiative, ReVAQ, with a wide range of different stakeholders was established in 2003. The aim was to identify approaches to be implemented to ...

The study presents information about the measurement techniques used for the assessment of air quality in terms of the olfactory intensity resulting from the operation of municipal sewage treatment plants. Advantages and disadvantages of the measurement techniques used are presented. Sources of malodourous substance emission from sewage treatment plants were described, and the malodourous subst...
