WASTEWATER TREATMENT

Two AquaDisk® Cloth Media Filters Replace Six Granular Media Units Boosting Capacity 540% And Cutting Backwash Volume By 97%

The Portland, Indiana, Wastewater Treatment Plant (WWTP) had been using six granular-media filter units for tertiary treatment since the 1980s. The plant’s treatment protocol includes fine screens for grit removal, followed by primary clarifiers, trickling filters, aeration basins, secondary clarifiers, the tertiary treatment system, and then chlorine disinfection.

    Biosphere™ Moving Bed Biological System Enabled Neptune Beach To Achieve Total Nitrogen Limits Without Additional Tanks

    Nutrients from growing coastal communities threaten bio-diversity: Bio-diversity in Florida’s St. John’s River estuaries is dependent on clean water. Growth in the area’s coastal communities is adding nitrogen and phosphorous nutrients to the river through wastewater discharges.  These nutrients cause rapid growth of some organisms, limit dissolved oxygen availability to others, and upset the balance of a diverse ecosystem.  In 2005, the Florida Department of Environmental Protection began implementing Total Mass Discharge Limits (TMDL) for nitrogen and phosphorous from the area's wastewater treatment plants.

    Sewer Authority Ends Plant Bypasses And Introduces Nutrient Removal With New Treatment Process

    The original contact stabilization activated sludge process at the Portage Area Sewer Authority generated hydraulic limitations that required repeated bypasses during heavy rainfall. Find out how the treatment plant upgraded its secondary treatment aeration system to include nutrient removal through a nitrification/denitrification/phosphorus process and has successfully processed I&I induced surges that reached a 10-MGD peak.

  • Making Accurate pH Measurements
    Making Accurate pH Measurements

    Like the old saying goes, give a man a watch and he always knows what time it is. Give him two watches and he never knows the correct time. What do watches have to do with pH? In this article, we will tie the analogy of accurate time to pH measurement and show how to make more accurate, dependable and believable pH measurements by using three pH sensors.

WASTEWATER TREATMENT PRODUCTS

Aeration

Aeration

ClearBlu Environmental focuses on complete aerobic digestion of organic waste. This process is desirable over anaerobic digestion because it is fast, odor free, and prevents the need for any solids removal procedures. Aerobic digestion is desirable over DAF systems because it eliminates the need for costly chemical use and disposal. ClearBlu uses a unique aeration technology known as microbubble aeration, to achieve an aquatic environment which supports a bacteria population capable of complete digestion.  This is the key difference over conventional technologies.

Aqua-Jet<sup>®</sup> SS-PW Aerator for Drink Water Applications

Aqua-Jet® SS-PW Aerator for Drink Water Applications

Aqua-Jet® aerators are installed in a wide variety of wastewater treatment schemes including activated sludge systems such as SBRs, MSBRs and extended aeration, as well as aerobic digesters, sludge holding, and equalization basins. It is also UL approved for TTHM stripping in potable water applications.

PASSAVANT® Tube Diffuser BIOFLEX®

PASSAVANT® Tube Diffuser BIOFLEX®

A tube diffuser BIOFLEX® consists of a support tube with an inside thread and slotted sleeve membrane. Two hose clamps fasten the membrane onto the support tube and an O-seal is applied for sealing between the distribution pipe and the diffuser element. To avoid buoyancy the support tube is flooded. Tube diffusers are usually installed in pairs either by a pipe clamp fixed on a round tube serving as a distribution pipe or by a double nipple inserted into a rectangular tube. When air is supplied, it is directed through the head of the support tube under the membrane. Through the slots of the membrane the air is smoothly dispersed into the wastewater.
