• Co-Digesting Food Waste With Wastewater Solids To Produce Energy

    Inspired in part by California’s Senate Bill 1383, which was enacted to reduce organic waste and methane emissions, co-digestion is fulfilling those goals while converting wastewater treatment plants into water resource recovery facilities.

  • How Beneficial Bacteria Are Helping Wastewater Operators Attack Biosolids

    Sludge handling presents a growing set of challenges for municipal and industrial wastewater operators, who are increasingly turning toward a natural solution. This alternative method results in a reduced biosolids load that lowers hauling and tipping fees, reduces process energy costs, cuts down odors, and fosters the natural cleaning of pipes and fittings.

  • Wastewater Sample Savings From Test Treatment Program

    Lower tipping and hauling fees, plant and site odor, processing times and more for the waste industries.

  • Bench Test Instructions For Your Case Study

    Natura Solve provides a complex liquid medium that is produced via a proprietary fermentation process. It consists of a selected spectrum of naturally occurring microorganisms, sustained within a matrix of micro elements and macro elements that provide the critical building blocks for respiration and growth. Thus it simultaneously works as both a biocatalyst, stimulating endogenous bacteria metabolic and production rate and a specialized delivery medium for the highly effective bacteria. The formula is very aggressive due to the essential balance between the selected groups of microorganisms, which, when combined with the enzymes they produce, synergistically create catalyzing proteins that significantly speed up the biochemical reactions and natural decomposition processes of the organic material into humic matter.

    Increasing profitability through efficient tailing and pregnant solution processing. 

  • Achieving Reliable Ammonia Removal In Lagoon-Based Treatment Systems

    For most small to midsize lagoon-based wastewater operations, maintaining effluent quality throughout the year is a challenge. Much of this is fueled by the difficulty of meeting permit limits for ammonia discharge, especially during winter months when the temperatures are colder. As a result, lagoon managers would benefit significantly from more reliability in the ammonia removal process.

  • Cloth Media Offers Chemical-Free Alternative For Advanced Primary Treatment

    Pile cloth media filtration technology has been around for decades, used mainly for tertiary wastewater treatment — a final stage of the treatment process — to filter effluent before it leaves the plant. However, the technology is now poised to provide extensive benefits as an advanced primary treatment technology. It stacks up well against other methods, which include chemically enhanced solutions that present additional operating costs and ultrafine screens that remove fewer solids.

  • AquaSBR® Replaces 60-Year-Old Treatment Plant

    The Moab Water Reclamation Facility (WRF) was initially constructed in the late 1950’s to provide primary treatment of domestic wastewater for the Moab area. However, the plant could no longer keep up with the higher flows and loading due to population growth and rising tourism. In addition, with aging infrastructure and the new permit cycle in sight, upgrades to the biological treatment were necessary to ensure full compliance. Read the full case study to learn more.

  • CASPERON Solution Brings Process, Operation And Cost Benefits To Michigan Facility

    For 15 years, plans to double the capacity of Michigan’s Zeeland Clean Water Plant remained stalled as the City of Zeeland worked toward a joint wastewater treatment contract with two neighboring Ottawa County communities. As a result, maintaining efficient aeration control posed a challenge for the 1.65 million gallons per day (MGD) facility. When expansion plans moved forward in 2016, the city alleviated those problems with the Xylem Sanitaire CASPERON activated sludge solution process, which eliminated the use of lime to treat waste and significantly reduced the volume of biosolid residuals.

  • Distillery Wastewater Byproducts Fuel Sustainability

    Every industry’s onsite wastewater treatment has its unique conditions and challenges. For distilleries, high levels of biochemical oxygen demand (BOD), nitrogen, total dissolved solids (TDS), and total suspended solids (TSS) put extra pressure on optimal biological treatment requirements. Here are some techniques that can help distillers put a little extra money in the bank while meeting the challenges of environmental discharge requirements.

This Parkson University video discusses sequencing batch reactors (SBRs), the process of biologically treating wastewater in a batch mode, and what differentiates Parkson's EcoCycle SBR from others. Learn how choice in operation and aeration type make Parkson’s SBR a desirable solution for biological treatment.
