  • Ink Manufacture

    An ink manufacturer was having poor results with the use of aluminum chloride and an anionic flocculent in treating their wastewater. The sludge was wet and sloppy requiring 4 man-hours to clean the press after each load. Chemistry costs were $110/1,000 gallons treated ($0.11/gallon).  Floccin 1106 was tested and found to treat the wastewater very consistently and the cost per batch was ...

  • Industrial Laundry-3

    The facility was trying to expand its market share by increasing the industrial linen operations. The facility washes a combination of ‘clean’ linens as well the ‘heavy’ linens from industrial clients in the form of shop towels, bar mops, and printer towels. The pretreatment system included the use of a 93% sulfuric acid, coagulant, calcium chloride for increased solids and settling rate, lime ...

  • 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 ...

  • A novel poly(acrylic acid-co-acrylamide)/diatomite composite flocculant with outstanding flocculation performance

    Series of anionic flocculants with outstanding flocculation performance, poly(acrylic acid-co-acrylamide)/diatomite composite flocculants (PAAD) were successfully prepared through aqueous solution copolymerization and applied to flocculate from oil-field fracturing waste-water. The structure of PAAD was characterized by Fourier transform infra-red spectroscopy , 13C nuclear magnetic resonance ...

  • Industrial Laundry-2

    This facility washes shop towels, uniforms, and floor mats from a variety of industrial clients. The wastewater has heavy metals, hydrocarbons, and oil/greases. The staff has heavily modified the treatment system with mixing tanks and longer detention time for the chemicals to work. The treatment consisted of lime addition, calcium Chloride, an aluminum based coagulant, and an anionic flocculant. ...

  • 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 ...

  • Extraction, characterization and application of malva nut gum in water treatment

    In view of green developments in water treatment, plant-based flocculants have become the focus due to their safety, degradation and renewable properties. In addition, cost and energy-saving processes are preferable. In this study, malva nut gum (MNG), a new plant-based flocculant, and its composite with Fe in water treatment using single mode mixing are demonstrated. The result presents a ...

  • Corrugated Sheet Plant

    The previous wastewater treatment was composed of the following chemicals: an acidic coagulant, caustic for pH adjustment, and an anionic polymer made down to 1% solution. The facility used 3-4 gallons of coagulant, 2-3 gallons of caustic, and 2-3 gallons of anionic flocculant (at a 1% solution) at a cost of $50/batch. The operator stated that they had low solids, they tended to overdose which ...

  • MBBR Helps Seafood manufacturer meet regulatory requirements

    Abstract Seafood processor in Manta Ecuador has a high strength wastewater with TSS as high as 20,000 mg/l, FOG 700 mg/l, COD of 13,000 mg/l and BOD of 6,000 mg/l. Wastewater is discharged into Pacific Ocean across the street from the factory. Current treatment plant produces effluent with TSS of 150 mg/l, FOG of 80 mg/l, COD of 800 mg/l and BOD of 400 mg/l on average. New laws require that ...

  • Corrugated Printing Facility Zero Discharge

    This company imports corrugated board and prints the labels using a flexographic machine. The facility had a wastewater treatment system using the traditional liquid chemistry of aluminum chloride, caustic for pH adjustment, and an anionic flocculant. The effluent was often out of compliance due copper from the color pigments in the inks. The system required continual adjustment of the 3 ...

  • Floccin for Metals Removal Beats Hydroxide Precipitation Hands Down

    The traditional approach for metals removal is Hydroxide Precipitation where the solubility for the metals changes to insoluble (precipitation) in the form of a metal Hydroxide as the pH increases. The common pH range for this is between 10-11 pH depending on the metal. Lime (calcium hydroxide or CAOH2), caustic (sodium hydroxide or NAOH) or magnesium hydroxide (MgOH2) are generally the chemicals ...
