  • Attitudes of farmers toward sludge use in the Gaza Strip

    The local production of organic fertiliser in the Gaza Strip is 66,800 m³/year, which represents only 8.5% of the required quantities. This means that farmers have to import 728,000 m³ of organic fertiliser per year, which costs around 10.2 Mio US$. The social survey carried out for more than 300 farmers in the Gaza Strip shows that the scarcity of organic fertilisers and their high prices could ...

  • Recovery of ammonium from digestate as fertilizer

    Ammonia inhibition can be a major problem during anaerobic digestion of manure and municipal and industrial sludges. Anaerobic digestion is sensitive to higher NH3-N concentrations, which are inhibiting and at certain levels even toxic for methanogen bacteria. The Nijhuis Ammonium Recovery (AECO-NAR) system can solve this problem and removes ammonium from digestate or other substrate for ...

  • Why are some French farmers sludge-takers? Some agronomic and socioeconomic explanations

    The continued spreading of household wastewater sludge on farmlands is a major economic and environmental issue. This practice is being challenged in France, mainly through pressure from the agrifood business. Here, by means of an agronomic analysis performed on 60 farms, we show the relevance of the following variables: proportion of arable land, technical performance of the farm, and quality ...

  • Agricultural Use of Different Residual Waste Composts - Current Situation and Experiences in France

    ABSTRACT Quality standards have been recently established in France for sewage sludge composts and other urban composts (greenwaste, biowaste and municipal solid waste composts). These standards allow to guarantee the innocuousness of the composts. Other standards have been defined in order to predict the compost effects on soil properties: the index of biological stability (ISB), based on ...

  • Chicken slaughterhouse

    Country: U.S. Problem: Poor final effluent quality Product: BFL 5100HP Background A chicken slaughterhouse was killing 10,000 chickens per day. Final effluent was discharged to a stream. The final effluent COD was exceeding the discharge limit of 100mg/L and as a result it had to be tankered off site and spread on ...

  • Effects of different composts on soil nitrogen balance and dynamics in a biennial crop succession

    Italy is faced with increasing pressures to reduce the amount of refuse disposed of in landfills. Compost represents a contribution to solve this problem. To give information for the correct management of composts as nitrogen fertiliser, it is necessary to assess their nitrogen release rhythm compared with the crop needs. This semi-field trial investigated the performance of three different ...

  • Animal Manure or Sludge Organic Fertilizer Production

    Introduction of Animal Manure or Sludge Organic Fertilizer Production Line Organic fertilizer production line is designed for producing organic fertilizer from animal manure or sludge, without any chemical ingredients. As chickens, pigs have a poor digestion, can only consume 25% of the nutrients, so other 75% of feed nutrients with feces discharge can be produced to the dry ...

  • Cattail plants’ Biomass as a bulking agent in sewage Sludge composting and the effect of the produced Compost on cattail plants’ Growth

    In every Greek island there is at least one town with more than 20,000 inhabitants. Several smaller towns and villages range from a few hundreds to a few thousands in population. Usually in the larger towns there are sewage treatment facilities providing at least secondary treatment of wastewater. In most cases the effluent produced is drained to the sea and the sludge is dumped in landfills. In ...

  • Full Scale Treatment of Slaughter House and Meat Packing Waste at Jennie-O Turkey Store, Barron, Wisconsin

    ABSTRACTJennie-O Turkey Store owns and operates a 0.057 m3/sec (1.3 MGD) treatment plant for treating wastewater from the slaughter of 26,000 turkeys per day. In 2000, Jennie-O Turkey Store was required by the Wisconsin Department of Natural Resources (WDNR) to remove phosphorous below 1 mg/l. The existing lagoon system with seepage cell was not removing phosphorous cost effectively and odors ...

  • Chicken Processing Plant (Ukraine (3))

    In this Chicken Processing Plant, the cost for sludge disposal had been extremely high since they disposed of sludge by tanker truck without sludge dewatering process. Because of the high sludge disposal cost, they had looked for a sludge dewatering equipment suitable for dewatering oily sludge, but could never find a solution. Solution Volute Dewatering Press ES-303 was ...
