  • Water mixing in waste lagoons

    Man-made lagoons have been used worldwide for the treatment of domestic and industrial wastewater, it seems, forever. All waste lagoons were first designed and thoughtfully planned considering their locations, soil makeup, and waste reduction processes prior to being implemented. The biological process of organic waste reduction is always a consideration of waste lagoon designs. There are three ...

  • Lumen Recommendations for Common and Industrial Work Spaces

    Lumen Recommendations for Common and Industrial Work Spaces Light brightness requirements for common and industrial spaces differ greatly. To achieve consistent, bright environments, the fixture’s luminous flux (or lumen [lm], which is the SI unit of luminous flux) must be taken into consideration. By definition, the term “luminous flux” (lx) refers to ...

  • Eliminating sludge islands in your wastewater lagoon

    Old municipal and industrial wastewater lagoons have the tendency to build islands of sludge at various locations around the lagoon. It is most common for older lagoons to build such islands wherever wastewater enters the lagoons. Of course, this is because the solids entering the lagoon have enough weight to fall out of the water as flow velocity is reduced, so the solids pile up just after ...

  • Treating pharmaceutical wastewater - Case Study

    A pharmaceutical facility in the Caribbean had an existing wastewater treatment process that utilized a sequencing batch reactor (SBR). SBRs use large tanks to collect wastewater, then a number of different options can be employed to treat the water (such as chemicals addition, aeration and mixing). When an SBR aerobically breaks waste down, it can produce a high volume of air that needs to be ...

  • Low energy mixing to optimize anaerobic digestion at the Kitchener WWTP

    The existing Kitchener Wastewater Treatment Plant (WWTP) is a conventional secondary treatment facility, with a rated capacity of 122,745 mVd. The plant is comprised of two separate secondary treatment plants (Plant 1 and Plant 2) served by a common headworks facilities and primary clarifier facilities. Plant 1 was constructed in the early 1960s and Plant 2 was constructed in the mid-1970s. Both ...

  • Los Angeles County WRRF Embraces Codigestion

    Technology to produce food waste slurry key to project implementation - and helps generators comply with California organics recycling mandates. The Sanitation Districts’ JWPCP in Carson (CA) treats an average of 280 million gallons/day of wastewater. One of the two anaerobic digestion tanks above has been used for codigestion, with the second serving as the control. Photos ...

  • Modeling the pH effects on nitrogen removal in the anammox-enriched granular sludge

    The aim of the study was to determine the pH effects on nitrogen removal in the anammox-enriched granular sludge. The experimental data were extracted from a 4 L completely-mixed batch reactor with the granular sludge at different initial pH values (6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5) and constant temperature T = 30 °C. Simulations were run in GPS-X 6.4 using a comprehensive mechanistic ...

  • Dinitrogen oxide (N2O) emission in the treatment of urban wastewater via nitrite: influence of liquid kinetic rates

    N2O emission was studied in a continuous process via nitrite for real urban wastewater treatment. The relationship between the gaseous forms and the liquid kinetic rates of nitritation and denitritation was investigated. N2O mass load and global nitrogen mass balance were quantified. The emission factor of the N2O (gN2Oemitted/kg mixed liquor volatile ...

  • Defluoridation of groundwater using mixed Mukondeni clay soils

    Excess fluoride in drinking water is harmful to human health and therefore it needs to be removed from water before consumption. The potential of locally available mixed Mukondeni clay soils (MMCS) as a cheap adsorbent for the removal of fluoride from aqueous solution was investigated. Characterization of MMCS was done by X-ray fluorescence, X-ray diffraction, scanning electron microscopy, ...

  • Case study - Supplemental aeration nearly eliminates filamentous sludge bulking

    The Dubai Investments Park Wastewater Treatment plant in the United Arab Emirates faced challenges in their oxidation ditch due to filamentous sludge bulking, resulting in poor sludge settling in the secondary clarifier. Supplemental aeration was needed to eliminate the filamentous sludge bulking. Challenge: The oxidation ditch is treating an ...

  • Household water insecurity is associated with a range of negative consequences among pregnant Kenyan women of mixed HIV status

    Water insecurity (WI) is a serious and worsening problem worldwide, but its role in health outcomes among people living with HIV or pregnant women is unknown. We assessed experiences of WI in a cohort of 323 pregnant Kenyan women of mixed HIV status. The majority (77.7%) had at least one experience of WI in the previous month; it was associated with negative economic, nutrition, disease, and ...
