  • 3 Reasons the FM100 Flowmeter Excels in Water and Wastewater Applications

    You might not guess by looking at it, but the FM100 Programmable Magnetic Flowmeter is an ideal fit for both water and wastewater applications. The combination of the FM100’s performance specifications and features make it uniquely suited to those environments and process requirements. ...

  • Boron removal from waste water originating in the open pit mines of Bigadiç Boron Work by means of reverse osmosis

    In this study, the base water originating in Simav Open Pit Mine containing the most important reserves of colemanite and ulexite boron minerals, has a boron concentration of 150 ± 50 mg/L, was treated to maximum 2 mg/L with the help of pilot RO system which was designed with two–phase reverse osmosis system. This system was designed and produced by Italian GEL Company. Temperature, pH, pressure ...

  • Reducing EC-TDS in Wastewater

    Integrated Engineers, Inc. has developed a product that will reduce the EC/TDS addition as compared to the use of acids/caustics for pH adjustment and coagulants in industrial wastewater. The products are our FloccinAgent tm product line, manufactured in Fresno, California. They add far less EC/TDS to waste streams and are usually equal or more cost effective than conventional wastewater ...

  • Mirror Plating Wastewater Treatment

    In the manufacturing of certain mirrors, a strong copper solution at low ph is used to apply a thin coating to the glass surface. After adhesion, the excess is washed off and collected as wastewater. The wastewater at this facility is treated using 4 chemicals: caustic to raise the pH to 8.5, DTC (dithiocarbamate) as a metal precipitant, an organic based coagulant, and an anionic flocculant. The ...

  • Ammunition Manufacturing

    An ammunition manufacturing facility was having problems removing copper and zinc from their 900 gpm wastewater system. The process used lime to raise the pH from 1.5 to 10, sodium carbamate for a metal precipitant, and an anionic flocculant to increase the flock size and get the solids to settle in the clarifier. Current chemical costs are estimated at $225,000/year with a significant amount of ...

  • Corrugator Sheet Plant 1

    A facility that made corrugated sheet board was using a specialty flocculant to treat their wastewater. Unfortunately, it treated the water only one half of the time to acceptable levels for reuse as starch makeup. The facility had paid $45,000 in the first 6 months of the year in chemical costs and $40,000 in haul-off costs to haul the majority of the treated water offsite. Integrated Engineers, ...
