  • The Municipal Water & Sewage Treatment Sector

    The best reason for the use of Albin Pump Hose pumps in this industry is the low maintenance of the pump. This industry readily accepts an average hose life of 1.500 - 3.000 hours in continuous duty and this hose life will provide much lower maintenance costs and repair time than with other pumps. Basic Pump Requirements For operation in an automatic system the following would ...

  • Co-composting of sewage sludge and municipal solid waste

    Israel production of sewage sludge and MSW grows each year due to the increasing number of modern Wastewater plants that are using activated sludge process and the increasing population. Non-stabilized Sewage sludge is an environmental nuisance due to high level of pathogens, offensive odours, insect attraction and potential water sources pollution. The Haifa region itself, where the study took ...

  • Austrian municipal sewage plant

    The sewage work of the borough Deutsch-Wagram is situated in the south west of the settlement on the left shore of the Ru§bach and is in operation since 1969. The drainage area is 350 hectare and the degradation performance is more than 90%. All accumulated waste water is cleaned by mechanical, chemical and biological treatment. At the moment only one activated sludge tank is used, the second one ...

  • Continuous Pyrolysis Facility for Sewage Sludge Treatment

    The amount of sewage sludge is catastrophically increased in the latest few decades due to functioning of the municipal sewage treatment facilities. Dry sewage sludge contains 70-90% of the organic substances and 10-30% of the inorganic substances, which are dangerous for human health in case of inappropriate utilization. The continuous pyrolysis technology presents the unique sewage sludge ...

  • The Method Found In A Sewage Sludge Carbonization Treatment Plant

    Have you ever passes a wastewater treatment plant and wondered exactly how the process works? Most localities have a minimum of one sewage sludge carbonization plant. These plants are the places where municipal sewage sludge is treated. This process is split into three stages. Each stage was created to further decompose and disintegrate wastewater sludge. ...


  • Pharmaceuticals in processing of municipal sewage sludge studied by grab and passive sampling

    Concentrations of pharmaceuticals, consisting of four anti-inflammatory and one antiepileptic drug, were studied in the aqueous and solid phase of municipal sewage sludge, collected from a wastewater treatment plant (WWTP) in central Finland. The samples included untreated municipal sludge from the biological wastewater treatment, digested sludge and sludge before and after composting. First, ...

  • Pyrolysis properties of municipal sewage sludge with ZnCl2 activation under the N2 atmosphere

    The municipal sewage sludge with ZnCl2 activation was pyrolysed to obtain useful porous adsorbents. The thermogravimetric analysis and FTIR methods were used to work out the properties of dried sewage sludge with ZnCl2 activation from the Changsha secondary wastewater-treatment plant. The experimental results showed that three stages of weight loss were observed under the heating rates of ...

  • Sustainable reuse potential of municipal sewage sludge in south–east Australia

    With the aim of reusing municipal sewage sludge, this paper presents the chemical and organic properties of sludge from a major sewage treatment plant in south–eastern Australia. The results show that the concentrations of all OCPs and majority of PAHs were below or close to laboratory detection limits. Concentrations of heavy metals in sludge samples were compared with typical sludge testing ...

  • Recycling of Municipal Wastes in Agriculture. I. Sewage Sludge Application to Corn Crop

    Abstract A two year’s field experiment (1995 and 1996) was conducted on a Typic Xerofluvent in order to study the influence of sewage sludge application on corn yield and nutrient uptake. Treatments included control (no sewage sludge, no mineral fertilisation), mineral fertilization (no sewage sludge) and sewage sludge application in total rates from 50 to 130 ton.ha-1 dry sewage sludge, applied ...


  • Characteristics and adsorption study of the activated carbon derived from municipal sewage sludge

    Sewage sludge-based activated carbon is proved to be an efficient and low-cost adsorbent in treatment of various industrial wastewaters. The produced carbon had a well-developed pore structure and relatively low Brunauer-Emmett-Teller (BET) surface area. Adsorptive capacity of typical pollutants, i.e. copper Cu(II) and methylene blue (MB) on the carbon was studied. Adsorptions were affected by ...

  • Toluene in sewage and sludge in wastewater treatment plants

    Toluene is a compound that often occurs in municipal wastewater ranging from detectable levels up to 237 μg/L. Before the year 2000, the presence of the aromatic hydrocarbons was assigned only to external sources. The Enhanced Biological Nutrients Removal Processes (EBNRP) work according to many different schemes and technologies. For high-efficiency biological denitrification and ...

  • Recycling municipal sludge with portable dredges

    Policing the pit. With today's emphasis on resource recovery, even burdensome and seemingly worthless materials are becoming increasingly valuable. Take municipal sludge, for example. For sewage treatment facilities wrestling with the problem of sludge disposal, Liquid Waste Technology may have the answer. The New Richmond, Wisconsin, USA company manufactures dredges and lagoon pumping equipment ...

  • Development of a novel epigeic-anecic-based polyculture vermireactor for efficient treatment of municipal sewage water sludge

    The potential of vermireactors, based on polyculture and monoculture system, was evaluated by using substrate consisted of domestic sewage sludge mixed with sugarcane trash, under laboratory conditions. Polyculture reactor was designed by using an epigeic (Eisenia fetida) and an anecic (Lampito mauritii) species of earthworm, while monoculture reactor had E. fetida only. Comparatively the end ...

  • Co-fermentation of sewage sludge and biowastes

    The anaerobic treatment of sewage sludge has a long history in Germany. It began early in the Twentieth Century with the development of the Imhoff tank and has, since then, been con-tinuously further developed. Today, anaerobic sludge digestion is the most widely used process for stabilizing sewage sludges. Digesters, in which a portion of the sewage sludge is converted into utilizable biogas ...

  • Co-digestion of press liquids of source-sorted municipal organic waste in anaerobic sludge treatment of municipal wastewater treatment plants

    This paper describes a semi-continuous laboratory-scale investigation of a potential co-substrate for mesophilic anaerobic sludge digestion in a municipal wastewater treatment plant. A feed liquid produced from source-sorted municipal organic waste by pretreatment with a screw press was subjected to the investigation. Quantities produced in press trials as well as the composition of the feed ...

  • Modification of UASB reactor by using CFD simulations for enhanced treatment of municipal sewage

    Up-flow anaerobic sludge blanket (UASB) has been in use since last few decades for the treatment of organic wastewaters. However, the performance of UASB reactor is quite low for treatment of low strength wastewaters (LSWs) due to less biogas production leading to poor mixing. In the present research work, a modification was done in the design of UASB to improve mixing of reactor liquid which ...

  • Ultrasonic Waste and Sludge Treatment

    Biogas is generated from sources, such as municipal organic waste, sewage sludge, muck or manure. Ultrasonication improves the digestibility of such organic material leading to more biogas and less residual sludge. Biogas is a byproduct of the decomposition of organic matter by anaerobic or aerobic bacteria. It consists primarily of methane, carbon dioxide and hydrogen sulfide. This makes biogas ...
