  • Dry Wall Manufacturer

    A Midwest manufacturer of dry wall (Gypsum wall board) products was unable to reliable treat their wastewater with conventional chemistry requiring hauling 1,000 gallons/week offsite at $1.00/gallon. Floccin-I was used to treat the water and they are installing a batch treatment system (capital cost at $20,000 installed) and will be treating their wastewater at less than $0.10/gallon. Payback ...

  • Waste Water Batch Treatment System

    Industrial Wastewater Treatment Batch Treatment Systems (BTS) are intended for lower daily volumes of wastewater typically less than 10,000 gallons per day and designed to “batch” treat wastewater from start to finish at one time. In a batch treatment system, a volume of wastewater is gathered, treated by chemical / physical / biological means, and discharged. Storage ...

  • Minimizing Arsenic Leaching from Water Treatment Process Residuals

    Ferric chloride addition was investigated for treatment of As-laden spent regeneration brine from ion exchange processes. Furthermore, varying conditions and calcium addition were investigated for the stabilization of the resulting As-laden solids. Arsenic, sulfate, bicarbonate, and chloride concentrations in the spent brine (300 mg/L, 605 mg/L, 305 mg/L, and 24 g/L, respectively) were orders of ...

  • Biosorption of Ag+ from aqueous solution by Streptomyces rimosus biomass

    The silver biosorption capacity of a Streptomyces rimosus biomass pretreated with NaOH was studied in the batch mode. Under optimal experimental conditions, a biosorption capacity of 63 mg Ag+ g−1 biomass was obtained. External mass transfer was found to be the controlling step in the overall sorption process. The equilibrium data poorly fitted the Langmuir and Freundlich model isotherms over the ...

  • Removal of 2,4-dinitrophenol from wastewater by adsorption technology: a batch and column study

    Red mud, an aluminium industry waste, was converted into low cost adsorbent and for the dynamic uptake of 2,4-dinitrophenol, which was sorbed by the developed adsorbent up to 95%. The removal of this pollutant was achieved up to 96% by column experiments at the flow rate of 0.5 mL/minute. The adsorption was found to be endothermic in nature. The qualitative and quantitative estimation of the ...

  • Dissolved oxygen as a factor influencing nitrogen removal rates in a one-stage system with partial nitritation and Anammox process

    A biofilm system with Kaldnes biofilm carrier was used in these studies to cultivate bacteria responsible for both partial nitritation and Anammox processes. Due to co-existence of oxygen and oxygen-free zones within the biofilm depth, both processes can occur in a single reactor. Oxygen that inhibits the Anammox process is consumed in the outer layer of the biofilm and in this way Anammox ...

  • Synthetic dairy wash-water treatment by using an alternating pumped sequencing batch biofilm reactor

    The performance of an alternating pumped sequencing batch biofilm reactor process in synthetic diary wash-water treatment was studied. The system comprises two reactors with two identical plastic biofilm modules. Two centrifugal pumps, one connected to each reactor, alternately move the water from one reactor to the other one, resulting in aeration. At three loading rates (336, 501 and 1080 g ...

  • pH Adjustment - A Primer

    A brief review of the definition of pH, the pH scale, and some of the chemistry involved in pH Adjustment systems is provided below. For some this may be trivial, yet for many others this may be useful. The information provided below is typical of the background information we provide in our training classes / seminars. By Definition pH is the measure of free hydrogen activity in water and can be ...

  • Water matrix effect on UV photodegradation of perfluorooctanoic acid

    The widespread detection of perfluorinated compounds (PFCs) in the water environment has been a concern for the last several years, while effluents from wastewater treatment facilities are the major sources of these compounds. Even advanced oxidation technologies (AOTs) are not useful for mineralization of the compounds due to their very high stability. Photochemical techniques using particularly ...

  • Formation potential of trihalomethanes (THMs) in blended water treated with chlorine

    This study was conducted in the laboratory to assess the formation potential of trihalomethanes (THMs) in blended water under various treatment conditions. Three batches of water samples prepared by mixing desalinated (product) water and ground brackish water with three different proportions (i.e. 1:2, 1:5 and 1:10 – brackish:product water) were treated with three concentration levels of calcium ...
