  • Headworks Screening for Smaller Plants

    Water treatment facilities in smaller towns and villages, as well as treatment works supporting institutions, prisons, resorts or remote facilities, have difficult choices to make when selecting a headworks system. All require a solids control strategy, but lower flows and smaller budgets limit the available equipment options. A number of different types of equipment can be used to meet these ...

  • Cost Trends of MBR Systems for Municipal Wastewater Treatment

    Cost estimates were developed for full-scale (1 and 5 MGD) MBR facilities designed to treat municipal wastewater. These estimates included both capital and operational / maintenance (O&M) costs related to the headworks, MBR process (biological process and membrane system), chlorine disinfection and effluent storage. The costs associated with the membrane systems were developed from budgetary cost ...

  • The Role of Activated Sludge Solids in an Actiflo® System

    ABSTRACTThis research was conducted using jar tests to investigate the impact of adding activated sludge solids to the Actiflo® process, a high-rate clarification (HRC) system, to increase BOD removal in HRC systems treating raw wastewater during periods of high wet-weather flows (WWF). A study of dosages and impacts of ferric sulfate, polymer, microsand and activated sludge on performance of the ...

  • Challenges in Designing an Odor Control System to Make a 32 mgd WWTP Odor Free

    INTRODUCTIONCity of Bakersfield located in Kern County, CA, is carrying out a major expansion to one of its wastewater treatment plants called Plant 3. Currently, Plant 3 treats about 15 mgd of wastewater flow with a design capacity of 16 mgd, on an Annual Average Dry Weather Flow (AADWF) basis. The current expansion will take the existing plant to an AADWF capacity of 32 mgd. As part of the ...

  • New Cloth Media Filter System Replace 4 MGD Traveling Bridge Filters with 12 MGD Capacity in Existing Tankage

    ABSTRACTThe Little Falls Run Wastewater Treatment Facility began experiencing operational difficulties with the dual-bay traveling bridge filter process as flows approached the rated capacity for the filters. Although initially the Utilities Department staff intended to duplicate the original filter process and thereby double the capacity, the recent introduction of a cloth media filter product ...

  • Implementation of an Innovative, Severe Duty, Grit Removal System at the Blue Plains Advanced Wastewater Treatment Plant in Washington, D.C.

    The District of Columbia Water and Sewer Authority’s Blue Plains Advanced Wastewater Treatment Plant has headworks facilities capable of treating an average daily design flow of 370 million gallons per day (mgd) and a design peak flow of over 1.0 billion gallons per day (1,000 mgd). The facilities are prone to very heavy grit loads during wet weather events, and the facilities are forced to ...

  • Biologically Engineered Biofilm Modifications for the Enhancement of Collection System Transformations and Impacts on BNR Wastewater Treatment

    ABSTRACTIncreased influent RBCOD and heterotrophic plate counts coincided with the start of bioaugmentation in this study. Observed influent sulfide levels were also lower duringbioaugmentation. RBCOD increases could potentially improve biological phosphorus or nitrogen removal. Lowered sulfides in the influent could lower corrosion and odors in the collection system ...

  • HD Q-PAC® Bio-media Eliminates Odors at Mt. Dora, Florida Water Reclamation Plant. System Very Responsive to H2S Surges

    The water reclamation plant at Mt. Dora, Florida had an odor problem at the headworks collection well. Several pump stations in the community send their water to this location. The discharge of the various lines is random. At times one line may be discharging water while other lines are idle. At other times multiple lines are discharging. There are periods of no water discharge at various times ...

  • Wastewater Treatment Plant, City of Marionville, MO

    Marionville is located in Lawrence County, MO. This town in America’s Heartland is tucked in Missouri’s southwest corner, less than 50 miles from Kansas, Oklahoma and Arkansas. The burgeoning tourist destination of Branson, MO lies in the bordering Stone County. Marionville has a population of roughly 2,140. The waste water treatment plant required a new Headworks system as part of a general ...

  • Mendocino case study

    As representatives of a small community, the Mendocino City Community Services District administrators felt strongly that they needed to deliver terrific wastewater treatment value at the lowest cost for their taxpayers. But they knew they needed to make a change, as their existing wastewater treatment system left unwanted solid accumulations at numerous points throughout their 1MGD treatment ...

  • 3k-tellerette packing-hclremoval-crossflow-scrubber-302

    A number of sources in the wastewater treatment process such as the headworks, aeration tanks, settling tanks and dewatering press can produce high-intensity odors from gaseous sulfide emissions. The most common sulfides arehydrogen sulfide (H2S) and methyl mercaptan (CH3SH.)The highlighted installation was for a major municipality in the southeast and utilizes our new high efficiency 3-K ...

  • Innovative approach to centrate nitrification accomplishes multiple goals: nitrogen removal and odour control

    In 2001, the City of Phoenix, Arizona (USA) committed to the conversion of the existing high-rate anaerobic digestion process at the 8.9 m3/s 91st Avenue Wastewater Treatment Plant (WWTP) to a multi-phase process (acid/methane, mesophilic/thermophilic) to optimise existing digestion capacity and achieve Class A biosolids. The improved solids reduction is anticipated to double the ammonia load in ...

  • The Italian Job

    Open loop systems abstract groundwater from one or more boreholes. Heat is either extracted or added by the primary refrigerant loop, and the water is returned to a separate well or body of water. The supply and return lines need to be placed far enough apart to ensure thermal recharge of the source. The key issues for open loop systems relate to borehole yields, licensing and, most importantly, ...
