  • Milk Processing Wastewater Treatment

    A milk processing facility was using a 800 hp evaporator to dispose of their 0.75% solids concentrated milk waste stream. The staff was interested in evaluating the effect of using the Floccin products to capture the majority of the BOD and send this higher % solids/BOD sludge to the evaporator. The idea was to reduce the electric hp by reducing the volume of water going to the evaporator. Their ...

  • Activated Sludge Diffusion Provides Cost Effective Biological Odor Control at Two Texas Wastewater Treatment Facilities

    ABSTRACTDuring recent expansions of the Rowlett Creek Regional WWTP in Plano, Texas and the Wilson Creek Regional WWTP in Lucas, Texas, activated sludge diffusion (ASD) biological odor control systems were installed to treat hydrogen sulfide (H2S) and other gaseous compounds. The ASD systems treat foul air collected from various sources, including headworks and primary distribution structures, ...

  • Advanced Enviro - Septic™ Wastewater Treatment System Septic Tank Effluent Filters and Charco al (Odor) Filters NOT Recommended

    Abstract: Effluent filters are installed in the outlet from the septic tank with the intended purpose of retaining solids inside the tank, preventing them from entering the treatment system and/or dispersal field. The concern is that if solids escape from the septic tank, they could cause clogging of the system components or the soil interface. While this may be a legitimate concern for some ...
