  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • Use of talc as low-cost clarifier for wastewater

    Talc is proposed as a low-cost mineral for wastewater clarification. In this sense, adsorption of methylene blue (MB) from aqueous solutions was studied comparatively by using sepiolite (qualified as very good adsorbent) and two talc samples with different particle size and purity degree. The MB adsorption was assessed by determining remnant dye in the supernatant using UV–vis ...

  • Oily Wastewater Processing Facility Wastewater Treatment Case Study

    Impressive Oil Water Separation This is the result of our Floccin 1105 product treating a sample from an oily wastewater treatment facility. As you can see, the Floccin 1105 was very effective at clarifying the waste as well as capturing all of the oil. These results were achieved with no pH adjustment and minimal Floccin addition (~ 1g/1000ml). The client is going to purchase and ...

  • Replacement of 130 ft Secondary Clarifiers at a 25 MGD wastewater treatment facility

    Challenge A municipal WWTP found that (2) of their secondary clarifiers were too rusted and corroded to properly function. A traditional clarifier refurbishment consisting of sandblasting and painting was not a viable option because one of the clarifier rake arms had recently broken due to its poor condition. The plant engineers decided that a clarifier rebuild was necessary to ensure ...

  • Coagulation and flocculation in water and wastewater treatment

    Coagulation and flocculation are an essential part of drinking water treatment as well as wastewater treatment.  This article provides an overview of the processes and looks at the latest thinking.  Material for this article was largely taken from reference (1). Coagulation and flocculation are essential processes in various disciplines. In potable water treatment, ...

  • Town of Manhattan Wastewater Treatment Plant

    The Manhattan treatment plant is a 400,000 GPD plant in two trains, containing six 24 x 5.0 Bio-WheelTM. It is able to nitrify and denitrify, with two anoxic basins ahead of the aeration basins. Two conventional flight and scraper clarifiers are used. Three Penn Valley RA S/MLSS pumps are located in a separate pump room. The plant is designed for a future expansion to 0.8 MGD. At this time the ...

  • Multispecies acute toxicity evaluation of wastewaters from different treatment stages in a coking wastewater‐treatment plant

    Coking wastewater contributes approximately 5% of the total discharge volume of industrial wastewaters every year in China. The toxicity of coking wastewater to aquatic organisms is still unknown. The authors evaluated the toxicity of wastewater from different treatment stages in a coking wastewater treatment plant, South China, using 5 test species belonging to different trophic levels: ...

  • Increasing the sludge energy potential of wastewater treatment plants by introducing fine mesh sieves for primary treatment

    The objective of this study was to compare some basic characteristics of sludge from fine mesh sieves (sieve sludge) with sludge from primary clarifiers (primary sludge) regarding their energy potential with a focus on anaerobic digestion and/or incineration. Nineteen samples of sludge from fine mesh sieve plants (most of them without fine screens and grit chambers as pre-treatment) and 10 ...
