Dissolved Air Flotation (DAF) Pilot System Achieves Removals In Excess Of 95 Percent
Dissolved Air Flotation (DAF) Pilot System Achieves Removals In Excess Of 95 Percent

The aluminum casting facility of a producer of semifabricated aluminum products utilizes a closed-loop contact water system that supplies water to multiple DC casting pits. An existing induced air flotation (IAF) system was used for the reduction of TSS, NTU, oil and grease, followed by a cooling tower. The treated and cooled water was then reused in the caster as contact water. The IAF had a removal efficiency of approximately 40 percent, required regular maintenance attention, operated at 125 HP and used an excessive amount of chemistry, resulting in extraordinarily high operating costs.

    FlexRake Bar Screens At 24+ Sites Around Houston Were Unaffected By Hurricane Harvey

    Despite the destruction of Hurricane Harvey in August 2017, Duperon® wastewater screening systems in the cities of Cuero and Refugio, Texas – approximately 150 miles southwest of Houston – were virtually unaffected by the storm. Duperon’s FlexRake® bar screens, installed at both locations as well as dozens of other sites in and around Houston, remove objects like rags, paper, plastics, and metals to prevent damage and clogging of downstream treatment equipment. Both communities found essentially no damage to their wastewater screening equipment.

  • The Rotostrainer Joins The Craft Beer Revolution
    The Rotostrainer Joins The Craft Beer Revolution

    Spent hops and general brewery wastewater are natural by-products of the beer-making process and must be reused or disposed of accordingly. Some brewers are charged substantial fines for dumping high-solids wastewater into the city sewer system. With Parkson Rotostrainers, over 90% of the Biological Oxygen Demand (BOD) of wastewater can be filtered out, greatly reducing the city sewer charges. Many breweries can even sell much of the spent grain and other captured solids to local farms as livestock feed, thereby profiting on an otherwise ‘waste’ product.

  • STRAINPRESS® Helps Fort Worth Turn A Liability Into An Asset
    STRAINPRESS® Helps Fort Worth Turn A Liability Into An Asset

    Scum is not a substance that anyone in a wastewater treatment plants wants to deal with. Scum, the greasy substance that floats to the surface of clarifiers, gets nastier as it accumulates. Some smaller wastewater treatment plants mix their scum back into other processing streams while other larger plants treat their scum separately. The City of Fort Worth takes a unique approach in managing its scum and now turns what was once a liability into an asset.
