WWTP’s Screw Press Reduces Odors, Saves Money, And Takes Up Less Physical Space
WWTP’s Screw Press Reduces Odors, Saves Money, And Takes Up Less Physical Space

A WWTP chooses a new screw press that takes up less than half the space that the old belt press had occupied. This was striking for the operations team but not as striking as the fraction of time they needed to spend managing the screw press.

  • Targeted Algal Management Plan To Address Taste And Odor Problem
    Targeted Algal Management Plan To Address Taste And Odor Problem

    Lake John Hay is located six miles northwest of Salem, Indiana and is used for drinking water and tournament and recreational fishing. With an average depth of 14-15 feet, it is ideal for algae and plant growth. The persistent, recurring algae blooms was causing taste and odor problems, which led to frequent complaints.

  • Fresh Water Aeration Solutions For Lakes, Rivers, And Reservoirs
    Fresh Water Aeration Solutions For Lakes, Rivers, And Reservoirs

    Aeration and mixing transform anoxic conditions in fresh water bodies. Adding oxygen to lakes, rivers and ponds decreases algae, eliminates anaerobic odors, and provides ice control in cold climates.

  • Five Years Of Post-Aeration At A Wastewater Treatment Plant
    Five Years Of Post-Aeration At A Wastewater Treatment Plant

    To protect the environment, wastewater treatment facilities across the country are required to deliver dissolved oxygen (DO) into the treated effluent, with most DO permits ranging from 2 to 10 mg/L.

  • North Carolina Treatment Plant Eliminates Taste And Odor Issues With Ozonation
    North Carolina Treatment Plant Eliminates Taste And Odor Issues With Ozonation

    Enactment of the Long Term 2 Enhanced Surface Water Treatment Rule and the Stage 2 Disinfectant-Disinfection Byproduct Rule (D/DBPR) will require both large and small drinking water utilities to reduce total organic carbon (TOC), Cryptosporidium, and disinfection byproducts (DBPs) in the treated drinking water distributed to the public.

    Wastewater Treatment System Achieves Stringent Water Quality Discharge Limits And Reduces Costs

    The Village of Johnson Wastewater Treatment Facility (WWTF) was among the first in the state of Vermont to meet newly enacted secondary treatment requirements when it began operation in 1970.

  • Mixers Prevent Buildup And Reduce Wetwell Cleaning Charges
    Mixers Prevent Buildup And Reduce Wetwell Cleaning Charges

    The City of Reno, NV, has long battled the buildup of fats, oils, and grease in the wetwells of wastewater lift stations in the valleys within this high desert city. Recently, the city set out to address the problem and reduce the associated costs.

  • Pilot Studies In North Carolina With Hydrex™ Odor Solutions
    Pilot Studies In North Carolina With Hydrex™ Odor Solutions

    Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H2S atmospheric concentrations of 300-500 ppm. Both clients desired H2S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.

  • WWTP Overcomes Odor Issue
    WWTP Overcomes Odor Issue

    The City of Crystal Lake is located about 45 miles northwest of Chicago with a population of nearly 45,000 people. Like many wastewater treatment plants, urban sprawl and suburban development puts the Crystal Lake Wastewater Treatment Plant near a host of commercial and residential neighbors, including a high school immediately west of the plant. Plant managers were very forward thinking, and wanted to be good neighbors to those occupying the surrounding area. They wanted to take steps to reduce — and hopefully eliminate completely — any odor issues from the plant.

  • A New Paradigm In Aeration Technology
    A New Paradigm In Aeration Technology

    The DO2E organization sprang from one individual’s attempt to solve an aeration problem in a fish hatchery and realizing that his device to do so had many other applications as well. This device broke up algal blooms as well as aerating, and it was only a short step to modify it into breaking up FOG (fats, oils, and grease) deposits in grease traps and lift stations. This device was patented, thus DO2E was born.

  • Odor Control For The City Of Houston
    Odor Control For The City Of Houston

    A supersaturated side-stream process (SDOX-CS®) was successfully deployed at temporary and permanent locations throughout the City of Houston for the effective control of collection system odors.

The MCS Odor Control Systems are single stage, skid-mounted, dry media systems, designed for relatively lower odor levels and organic odors. The media may be virgin activated carbon or any of a number of specialty catalytic carbon media. Standard models are available to treat up to 1,400 cfm (2400 m3/h) of odorous air.

I-BOx&reg; Biological Odor Control Systems I-BOx® Biological Odor Control Systems

The I-BOx® Biological Odor Control Systems (patent pending) use a two-stage process with a biological stage to remove 99% of the hydrogen sulfide (H2S), followed by an activated carbon polishing stage to remove residual H2S and organic odors. Standard models are available to treat up to 5,000 cfm (8500 m3/h) of odorous air.

Carbon Odor Control Systems - BCS Series Carbon Odor Control Systems - BCS Series

The BCS Odor Control Systems are larger bulk media systems, designed for higher air flow rates. The media may be virgin activated carbon or any of a number of specialty catalytic carbon media. Standard models are available to treat up to 6,800 cfm (11600 m3/h) in a single carbon stage and up to 20,000 cfm (34000 m3/h) in a dual bed system.
