  • Impact of heating method on the flocculation process using thermosensitive polymer

     Flocculation process based on water soluble polymers as flocculating agents is still intensively researched nowadays, despite the introduction of these materials about fifty years ago. There is a need to gain the full control of this process in order to obtain high efficiency and strictly define products. For that purpose new solutions are proposed like stimuli-responsive macromolecules. In ...

  • Integrated Engineers Case Study: Circuit Board Manufacturer

    A circuit board manufacturer in southern California was not able to achieve the discharge levels of copper and nickel with their existing system of coagulant, anionic and cationic flocculants and metal precipitant treatment process followed by lamella plate clarification. The previous treatment process developed a settled sludge that had poor shear characteristics and required further coagulant ...

  • Uncertainty Analysis in Wastewater Engineering Modeling: Understanding the Limitations

    ABSTRACT Design engineers commonly rely on physical and mathematical approximations or models of real complex phenomena. During the development of these physical or mathematical models, simplifications and assumptions need to be made to develop such tools. It is unrealistic to expect that the modeling process will give an answer that is a perfect match to the real case, and it is, therefore, ...

  • RO Pretreatment Hydrocarbon Engineering - Optimisations of Osmosis

    Desalination by reverse osmosis (RO) is a fast growing technology, which is gaining more and more market share in the field of desalination applications. RO plants are able to produce extremely pure water with minimal impurities, even if they are charged with highly contaminated feed water. Based on the fact that the RO membranes themselves are able to separate the smallest ions out of the raw ...

  • A review of the detection, fate and effects of engineered nanomaterials in wastewater treatment plants

    Engineered nanomaterials (ENMs) are increasingly found in a wide range of products and processes, and consequently increasing loads are expected to reach wastewater treatment plants (WWTPs). To better assess the potential risk of ENMs to the environment via input through WWTP effluents, this review considers ENM detection methods, fate in WWTPs and potential effects on biota exposed to ...

  • Die Casting

    A sample of wastewater was received from firm in the south central region of the US. The client could not get sufficient flocculation, despite using 10 lbs. of another dry flocculating material. The sample had an initial pH of 6.5. The sample contained glycol, mineral oil emulsion, wax polymers and soap for cleaning the floor. The sample was flocculated with Floccin K. The material formed a good ...

  • Poultry Food Case Study

    This facility processes, seasons, cooks, and flash-freezes poultry for the food industry. They process about 500,000 lbs. of chicken per day and are trying to increase their production. Their existing wastewater system was limited in its ability to meet the discharge requirements to the local POTW and was therefore required to meet these limits as a condition of their expansion. To expand ...

  • Latex Paint Manufacturer-1

    The paint manufacturing facility was using 1 MGD of fresh water in the manufacturing process with a majority of the water being used for tank and pipe cleaning. As a cost cutting measure, the facility wanted to reduce the water consumption and reuse part, if not all of the wastewater. They tried several different combinations of coagulants and flocculants with limited success. Integrated ...

  • 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 ...

  • Latex Paint Manufacturer-3

    Integrated Engineers, Inc. did the following treatability on the wastewater produced at a Latex Paint manufacturing facility. The treatments required no pH adjustment. The best product was treated with 0.3 grams of Floccin-K in a 100 ml sample and required moderate mixing (1 minute). The dosage equates to a treatment of 25 lbs/1,000 gallons. At an end consumer price of $2.00/lb., the treatment ...

  • Metal Processing Facility 2 Wastewater Treatment

    Integrated Engineers, Inc. conducted the below treatability on a Metal Processing facility that uses soluble metal cutting oils in their machining process; below are the results. The treatment required no pH adjustment from the 7.0 pH. The best product was treated with 0.679 grams of Floccin-HP (powdered) in a 100 ml sample and required moderate mixing. The dosage equates to a treatment of 56 ...

  • Oil Field Sludge Dewatering

    An oil field contract dewatering company was unable to dewater the oily/water/solids from several oil field storage tanks using conventional coagulants/flocculants. The swings in solids loading and oil content made it very difficult to control the correct dosage rate as conventional chemistry has a very tight tolerance to maintain a dewaterable floc. The result was an ongoing blinding problem for ...

  • Metal Polishing

    Integrated Engineers, Inc. conducted a treatability test for a facility that polishes stainless steel. We were asked to assist them in meeting their local discharge requirements as the flocculant they had been using was not working sufficiently. The initial pH of the wastewater upon arrival was 7.0. 3.0 grams of Floccin-G was used per 1000 ml jar of wastewater. After mixing for 10 minutes, the ...
