  • Six months treatment cut 95% of priority PAH pollutants from coke oven effluent

    Six months treatment cut 95% of priority PAH pollutants from coke oven effluent. Citadel Biocat+TM provided the bioremediation in situ of 150,000 cubic meters of contaminated soil at a decommissioned coke oven effluent lagoon. Several decades of steel production had created a residue of significant amounts of polycyclic aromatic hydrocarbons (PAH’s), along with soluble components such as ...

  • Membrane-integrated hybrid bioremediation of industrial wastewater: a continuous treatment and recycling approach

    A new membrane-integrated hybrid treatment system was investigated to turn highly hazardous coke wastewater reusable. This could protect both air and surface water bodies from toxic contaminants such as ammonia, phenol, cyanide, thiocyanate and other carcinogenic aromatic compounds which are normally released into the environment during discharge of coke wastewater and during quenching of coke ...

  • The Evolution of Plug Flow BNR at Durham AWWTP

    ABSTRACTThis paper describes experiences with plug flow nitrification and plug flow biological nutrient removal (BNR) at Durham Advanced WWTP. The kinetic advantages of the plug flow configuration for nitrification have been recognized for some time; however, limited plug flow BNR process design information was available at the time (1997). The case study began with pilot testing in 1998, during ...

  • Odor Control Advances at Composting Facility

    The Rockland County (New York) Cocomposting Facility began operations in February, 1999, processing biosolids from the five publicly owned treatment works (POTWs) in the county. The Rockland County Solid Waste Management Authority (RCSWMA) owns the facility, but contracted with Waste Management of New York to design, build and operate (DBO) the 110 wet tons/day agitated bin composting facility ...

  • A multi-parameter analyzer helps a Kentucky treatment plant step up to the plate and meet a new phosphorus limit in its permit

    In 2001, the Lexington Fayette Urban County Government West Hickman Creek Wastewater Treatment Plant in Nicholasville, Ky., was starting Phase II of its third upgrade since 1972, when the state imposed a phosphorus limit. Total phosphorus hovered around 6 mg/l, but the permit required 1 mg/l monthly average and 2 mg/l daily maximum from May through October. Engineers from Tetra-Tech, the ...

  • Achieving Stringent Effluent Limits Takes a Lot of Energy!

    Enforcement of increasingly stringent effluent limits, and application of more sophisticated treatment processes for reduction of chemicals of potential concern, increases the energy consumed in municipal wastewater treatment processes. Energy consumption factors (ECFs) have been developed for wastewater treatment plant configurations based on the quantity of electrical energy used per cubic ...

  • Struvite belt press removal case study

    A wastewater treatment plant near Flagstaff, AZ was experiencing problems with keeping their belt aligned on the belt press. The belt press was in operation 4 days per week for 6 hours per day. The flow rate was 150 gallons per minute (gpm). Upon close inspection of the belt press system, the maintenance staff observed scale deposits on the rollers, pan and filtrate lines. Samples were taken for ...

  • Mixing To Enhance Facultative Wastewater Lagoon Treatment

    SolarBee® & GridBee® Are Leading The Way In most lagoons, sunlight causes a hard stratification at 12 to 18 inches of depth.  The top water is warmer and thick algae populations are producing supersaturated dissolved oxygen (DO).  The DO gasses off at the surface and is not readily available deeper in the pond for use by BOD-reducing bacteria. Meanwhile new ...

  • Cost Containment: Beyond the Obvious

    Utilities today can implement a number of different initiatives to help them contain costs and maximize profits. Some of those, such as switching to a more efficient fuel source if possible, can produce obvious results that are relatively easy to calculate. But there are other initiatives, though less obvious, that can produce significant results at the bottom line. One such cost-containment ...

  • Efficient Waste Water Treatment

    Clean drinking water is an essential need of mankind. Often surface water like rivers or lakes is used as drinking water source. To prevent these resources from pollution the effective treatment of waste water is a must. For example in China 75% of discharged waste water is coming from pulp and paper, textile and dyeing industries. To run a waste water treatment plant in the most efficient way ...
