• Oily Water Treatment: How To Treat Using Advanced Electrocoagulation

    We cook with it. Use it on our skin. Paint with it. Use it to fuel our cars. Our own bodies even produce it. However, something doesn’t quite add up here. Clearly, you wouldn’t cook with motor oil and you wouldn’t put olive oil in your gas tank. So why do we call these different products by the same general name? What oily water treatment is used to treat these different types of emulsified oils?

  • Pros And Cons Of Wastewater Treatment Methods: Coagulation And Disinfection

    Every stage in a wastewater treatment process is important to achieve the desired treatment results. However, primary treatment and tertiary are critical to the overall process. In the primary treatment process, solids are reduced to a large extent. Without this step, subsequent treatment would be less effective. In tertiary treatment, harmful microbiological matter is rendered killed or inactive so that it will not cause sickness to those organisms that encounter it.

  • Achieving Water Authority Compliance With Automated Wastewater Treatment

    Automated wastewater treatment systems help manufacturers remain in compliance with EPA and local standards, while significantly reducing the cost of treatment, labor, and disposal.

  • Common-Sense Perspectives On Waste Treatment — With A 'Western' Flair

    I have been in the waste treatment business for some years now, and I am continually surprised with what I see promulgated by the people that do this every day and should know better. Out West (Texas, actually), we see life as a more or less continual struggle with all kinds of adversaries. Collectively we call them varmints, and they are ever present as we go about our daily duties. There is much to be learned from folklore in establishing a common-sense perspective, and the convergence of Texan culture and waste treatment technology (and even water treatment) are cases in point.

  • 4 Benefits Of Electrocoagulation For Food And Beverage Wastewater Treatment

    With a global population of over seven billion people, there are hundreds, if not thousands, of companies in the world that produce the food and beverages that are needed to meet this global demand. These companies require massive amounts of water to produce their products, and those products result in equal amounts of wastewater. It’s simple enough to just discharge the wastewater into a nearby stream or surface water source and be finished with it. However, with constantly changing environmental regulations and pressure to be more environmentally conscious, food and beverage companies face increasing requirements of beverage and food wastewater treatment.

  • Combining Biosolids Waste Streams? Not So Fast…

    The idea of combining two systems into one sounds like a common-sense solution to simplifying operations.  Wastewater treatment plant operators have been experimenting with this concept by combining waste activated sludge with primary and septage waste streams with the goal of lowering system complexity.  The reality of these efforts is proving, in many cases, to be problematic.

  • Sludge Thickeners: The Good, The Bad, And The Smelly

    Management of wastewater sludge is a core responsibility of treatment plant operators. With this responsibility comes common challenges that must be overcome.  These include controlling odors so as to have a minimal impact on the surrounding community and minimizing hauling costs for its disposal.  Getting a handle on both of these responsibilities and more can be much easier with the proper sludge-thickening equipment.

  • Sludge Sampling For Polymer Selection — Critical For Project Success

    Polymers — the chemicals used in wastewater to thicken sludges and facilitate the removal of water — are critical to the operational efficiency of sludge-thickening equipment. Unfortunately, it’s common practice at treatment facilities to order and install equipment before even considering what the ideal polymer might be for the sludge produced at the specific plant. This flawed process is time consuming, disruptive to plant operations, and can become very costly.

  • How To Boost Wastewater Treatment Capacity Within An Existing Footprint

    Municipalities can find themselves in a real bind when wastewater treatment operations are strained by population growth. That’s because facilities are either landlocked and can’t expand at their current location, or the prospect of building an addition isn’t in the budget. When the bottleneck is at the digesters — the tanks where microorganisms break down waste — there are some common-sense strategies treatment plants can employ to address those growing pains.

  • 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.

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.
