  • An analysis of the environmental management elements related to the improvements of the drying kinetics of waste activated sludge by Fenton peroxidation

    Advanced sludge treatment processes (AST) reduce the amount of sludge produced and improve the dewaterability, thus probably also affecting the heat transfer properties and the drying characteristics of the sludge. This paper studies the influence of the Fenton peroxidation on the thermal conductivity of the sludge. Results demonstrate that the Fenton's peroxidation improves the sludge cake ...

  • Septic Tank for Commercial Building (Ukraine (2))

    As for this septic tank, thickened sludge had been pumped to a tanker truck for disposal 2-3 times a month. However, there had been longstanding concerns confronted by the end user. Their concerns were not only the high sludge disposal cost but also the odor which comes along with the presence of a tanker truck. They had looked for a suitable sludge dewatering unit for small-scale wastewater ...

  • Lead Plating

    A Midwest company is plating lead and etching the material with an HCl batch. The resultant wastewater had a lead concentration of 2,000-4,000 ppm. Traditional chemistry (pH adjustment to 9.8, coagulation/flocculation) could only decrease the concentration to 5.0 ppm. The facility was had to retreat the wastewater and only then could reach a lead level of 3.0 ppm.  With the use of the ...

  • Waterschapsbedrijf Limburg (WBL) - case study

    Along with WBL Sustec has tested and lab researched  the continuous thermal hydrolysis of the surplusslib of the wastewater treatment plants Hoensbroek and Venlo. On this basis is determined the most optimal hydrolysis method. Then for nine months on pilot scale tests were carried out to the thermal hydrolysis and fermentation of the surplusslib. The tests confirmed that by thermal ...

  • Phyto-dewatering of sewage sludge using Panicum repens L.

    Experiments in the field environment have been conducted to study the growth of Panicum repens L., an aquatic plant, in the sewage sludge matrix. The experiments were also carried out to investigate the ability of this plant to dewater sewage sludge to increase the capacity of conventional drying beds. In addition, the ability of Panicum repens L. to reduce the sludge ...

  • Nitrogen removal in tertiary wastewater treatment plant of a chemical complex

    A Biochemical Contact Oxidation Film (BCOF) technique was piloted for the treatment of a secondary effluent of the Jilin Chemical Industry Corporation (JCIC). The original pulse contact flocculation clarifier used for the tertiary treatment was not performing to the discharge standards. Results show that NH3-N concentration was decreased from 30 mg/L to 15 mg/L, COD concentration was decreased ...

  • Energy recovery from thermal treatment of dewatered sludge in wastewater treatment plants

    Sewage sludge is a by-product generated from municipal wastewater treatment (WWT) processes. This study examines the conversion of sludge via energy recovery from gasification/combustion for thermal treatment of dewatered sludge. The present analysis is based on a chemical equilibrium model of thermal conversion of previously dewatered sludge with moisture content of 60–80%. Prior to ...

  • Evaluation of Alternative Operation Modes for Aerobic Digester at the Fountain Hills Sanitary District Wastewater Treatment Facility

    Recycle streams from sludge digestion facilities to activated sludge processes can be important in the overall performance of wastewater treatment facilities. The recycling streams at the wastewater treatment plant for the fountain Hills Sanitary District Wastewater Treatment Plant include digested sludge dewatering centrate, waste activated sludge thickening centrate, and filter backwash water. ...

  • Three years of operation of North America's first nutrient recovery facility

    The first full-scale nutrient recovery installation in North America became operational in May 2009 at the Clean Water Service's Durham Advanced Wastewater Treatment Plant in Tigard, Oregon. Recovering ammonia and phosphorus from the dewatering side stream as struvite has a positive impact on plant operations. Significantly reducing the phosphorus recycle lowers the phosphorus loading on ...

  • Effect of ambient temperatures on disinfection efficiency of various sludge treatment technologies

    Sewage sludge produced during municipal wastewater treatment has to be treated efficiently in order to reduce impacts on the environment and on public health. In Germany and many countries, large quantities of sludge are reused in agriculture in order to recycle nutrients and organic material. In order to quantify the effect of different ambient temperatures on conventional and advanced sludge ...

  • A case study of the sludge thickener - Large Commercial Facility (Office Building)

    Costs for industrial waste reduced with sludge thickener Some office buildings and large commercial facilities have wastewater treatment facilities underground. In such case, it is difficult to take dewatered cake out, so sludge is kept in liquid form and vacuumed out by pump without being dewatered. This potential customer also had been vacuuming out the liquid sludge, and had considered how to ...
