  • Microfiltration for treatment of waste filter washwater at water treatment plant

    The North Jersey District Water Supply Commission (Commission) serves about 2 million consumers from its 210 mgd water treatment plant (WTP) in Wanaque, New Jersey, about 25 miles northwest of Manhattan. Raw water is obtained primarily from the adj acent Wanaque Reservoir, and the nearby Pompton and Ramapo Rivers. The Wanaque WTP provides conventional treatment with chiorine as primary ...

  • Nitrogen removal in tertiary wastewater treatment plant of a chemical complex

    A Biochemical Contact Oxidation Film (BCOF) technique was piloted for the treatment of a secondary effluent of the Jilin Chemical Industry Corporation (JCIC). The original pulse contact flocculation clarifier used for the tertiary treatment was not performing to the discharge standards. Results show that NH3-N concentration was decreased from 30 mg/L to 15 mg/L, COD concentration was decreased ...

  • Outbreak of acute gastroenteritis due to a washwater-contaminated water supply, Switzerland, 2008

    An operating error in a sewage treatment plant led to severe drinking water contamination in a well-defined district of a suburban municipality of Zurich, Switzerland. Despite the alert issued to the local population on the same day advising people not to consume the contaminated water, cases of acute gastroenteric diseases were subsequently observed. Considerable faecal contamination was ...

  • Other Treatment Technologies

    Reuse/Recycle: Recovery and reuse technologies for energetic materials, including both explosives and propellants, should be considered at explosives waste sites for several reasons. First, new recovery methods and potential uses for reclaimed explosive materials are rapidly developing. Second, recovery/reuse options reduce overall remediation costs by eliminating destruction costs and allowing ...

  • Treatment of Water-Wash Paintbooth Effluents in the Automotive Industry

    During the coating process of car bodies in water-wash spray booth, around 40% of the sprayed paint does not reach the support; these paint particles sprayed into the air are called “overspray”. By using a dawn-draft positive air pressure coming from the ceiling of the cabin, the polluted air is forced vertically downward toward a grating on the floor under which a constant stream of water is ...

  • 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 ...

  • Slurry Phase Biological Treatment

    Slurry phase biological treatment involves the controlled treatment of excavated soil in a bioreactor. The excavated soil is first processed to physically separate stones and rubble. The soil is then mixed with water to a predetermined concentration dependent upon the concentration of the contaminants, the rate of biodegradation, and the physical nature of the soils. Some processes pre-wash the ...

  • Egg wash wastewater: Estrogenic risk or environmental asset?

    Commercial production of eggs and egg products requires the washing of eggs to remove urinary / fecal material and broken egg residue. In the case of one Ohio farming facility, 1.6 million birds produce 1.4 million eggs per day, using ∼50 mL of wash water / egg or ∼ 70,000 L per day. The aqueous waste stream was evaluated for estrogenicity, to determine if potential for endocrine disruption ...

  • Common Treatment Technologies for Explosives in Ground Water, Surface Water, and Leachate

    Explosives-contaminated process waste waters can be subdivided into two categories: red water, which comes strictly from the manufacture of TNT, and pink water, which includes any washwater associated with load, assemble, and pack (LAP) operations or with the demilitarization of munitions involving contact with finished explosive. Despite their names, red and pink water cannot be identified by ...

  • HydroThane T&C case study

    Application in Dairy Industry Technology & Contracting On January 2011 HydroThane has been awarded with a contract to supply design and the anaerobic hardware but also all auxiliary equipment and project management/supervision services for the dairy of TYRAS in Greece. Having the aim to achieve the required quality standard, the local civil work and ...

  • On-site treatment of used wash-water using biologically activated membrane bioreactors operated at different solids retention times

    Biologically activated membrane bioreactors (BAMBis) were operated at suspended solids retention times (SRT) of 7 and 102 days and at full solids retention. The effect of these different approaches of operation on the substrate and nutrient conversion, and on permeate flux, was investigated. Variations in organic loads and aeration intensities were also studied. Permeate flux stabilized during ...

  • Rold Model Water Recycling Program

    ABSTRACTThe Viejas Band of Kumeyaay Indians, a federally recognized tribe, vested with authority by the U.S. Environmental Protection Agency (USEPA), form the Tribal Government to regulate all activities concerning water quality issues within the reservation boundaries. The Reservation has 400 non-transient residents and an average of 5,000 transient residents. The transient population visits the ...

  • Control VOC`s in Refinery Wastewater

    Oil and water do not mix, like many of life’s one-liners this statement is basically true but not the whole story. Many hydrocarbon liquids, particularly aromatics, have significant solubilities in water: Benzene 1800 PPMVToluene 470Ethyl Benzene 150Xylenes 150 Petroleum refineries do not like salts in their feedstock since these corrode and foul process equipment. The first refining step is ...
