  • A new strategy for treating a cotton dyeing wastewater – integration of physical-chemical and advanced oxidation processes

    New strategies were herein applied for treating a cotton dyeing wastewater: coagulation/flocculation followed by Fenton’s oxidation – approach 1, Fenton process per se – approach 2, and Fenton followed by coagulation/flocculation – approach 3, aiming reducing chemicals consumption. Regarding the cost analysis, which is crucial for deciding on the best strategy to implement, it was found that ...

  • Petrochemical Refinery invests in automated COD analysis system utilizing new PeCOD technology (case study)

    Background  A petrochemical refinery has 6 different wastewater sampling points for effective process control. When there is a problem in effluent COD, samples from all 6 points are needed to determine source of the contamination. Once the contamination source is determined, corrective actions are taken. Problem The current COD dichromate test ...

  • BM respirometry study about nitrification inhibition and actual aeration capacity in an activated sludge process case study

    Study for municipal WWTP in Spain This study is ordered to SURCIS as a consequence of the low process performance, practical absence of nitrification treatment. By other side, the mixed-liquor presented some abnormal features such as weakness, dark colour and abundant white foaming. Data for study interest Aeration system: fine ...

  • What are the treatment options for landfill leachate?

    New contributor to Water/Waste Processing aims to answer readers’ most pressing questions It’s said the United States has 1,654 landfills, handling more than 250-million tons of trash each year. One Washington landfill covers a 2,545-acre area, has a 120-million-ton capacity and a 40-year expected trash-receiving life. The facility, the Republic ...

  • Data Requirements for Soil, Sediment, and Sludge

    Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

  • Real-time TOC tightens effluent control at Greencore

    A food manufacturing facility in Selby has installed a new continuous TOC (Total Organic Carbon) monitor, ‘the BioTector’ which has dramatically improved the site’s capability to refine and improve the plant’s wastewater treatment process. As a result the plant is better able to quickly respond to changes in the influent. Greencore Foods is a leading player in the food ...


  • Taming taste and odor (T & O) problems in a water treatment plant

    Taming Taste & Odor (T&O) Problems Some taste and odors are caused by mineral constituents in the water, e.g. excess chlorine and hydrogen sulfide. However the majority of taste and odor are the result of biologic activity. Spring turnover of lakes and algal blooms are responsible for Blue-green algae (Cyanobacterium), Green algae and diatoms that introduce filter clogging organisms ...
