Wastewater Treatment Case Studies and White Papers

  1. Mixers Prevent Buildup And Reduce Wetwell Cleaning Charges

    The City of Reno, NV, has long battled the buildup of fats, oils, and grease in the wetwells of wastewater lift stations in the valleys within this high desert city. Recently, the city set out to address the problem and reduce the associated costs.

  2. Assessing Key Unconventional Shale Wastewater Trends And Opportunities

    The shale-gas boom could make water the most important commodity product of the 21st century.

  3. Microbiological Monitoring Of Paints Using 2nd Generation ATP

    A paint manufacturer produces a wide range of paint products for industrial, commercial, and residential applications. The products are manufactured in large batches of up to 10 tons. Before each batch is packaged and shipped, a number of tests are performed to ensure that the product meets strict quality control requirements. 

  4. Fixed-Film Treatment System Handles Fluctuating Population Changes With Ease

    A retreat and camp facility struggling with variable flow conditions and associated wastewater issues turns to a fixed-film treatment system designed just for that application. The results have far exceeded expectations: treatment quality surpasses permit levels and regular operation and maintenance requirements are at an all-time low.

  5. Plastic Flow Meters Reduce Weight, Space, Corrosion — Not Accuracy

    There are a variety of reasons for wanting accurate flow metering — e.g., billing purposes, precise proportioning of chemical injections, and other process flow decisions. That is why highly accurate mag meters are so popular in many applications. Now, new lightweight, corrosion-resistant mag meters provide the same advantages as plastic piping for harsh environments and flows that cover all the bases…and acids.

  6. Seeing Through The FOG (Fats, Oils, And Grease)

    A review of different methods and devices for FOG removal, with emphasis on cost control, lowered power profiles, and efficacy. By Douglas D. Sunday, water and wastewater Class A operator and Dr. J.H. Wakefield, consulting analytic chemist and environmental/materials engineer

  7. Overdosing, Underdosing, And How To Get Precise With Wastewater Treatment Chemicals

    Despite their best intentions, wastewater operations all over the country have suffered from accidently under- or over-administering treatment chemicals when trying to get effluent into shape. With the proper tools, however, these mistakes can become a thing of the past.

  8. New Membrane Technology Handles High Solids, Aids Water Reuse

    As global conditions place more stress on water resources, a great deal of attention is being paid to water reuse technologies, particularly those that facilitate the reuse of the next level of difficult-to-treat or highly variable raw water sources.

  9. United Utilities Adopts Collaborative BIM Strategy To Deliver Over 200 Water Projects

    Privatization of the United Kingdom’s (UK) water industry 25 years ago required providers to implement asset management programs (AMP) whereby water boards tendered contracts to construction firms to update the industry’s antiquated assets and help keep infrastructure properly maintained. 

  10. Start-Up And Operating Tips For Jet Aeration Systems

    Jet aeration systems are extremely efficient due to their high alpha factor and clean water oxygen transfer performance. Proper start-up, operation, and maintenance will ensure reliable service and a long life.
