Wastewater Case Studies and Whitepapers

1. MBBR System Implements Nitrogen Reduction Plant Improvements 5/3/2019

   Hopewell Water Renewal (HWR) is a 50 MGD secondary wastewater treatment plant that treats the wastewater from local industries and domestic sources of the Hopewell, VA area. The plant began operating in 1977 and treats approximately 85% industrial waste. The facility achieves the treatment permit requirements for both BOD and TSS; however, treatment regulations have changed over the years and now require the removal of nutrients. HWR discharges effluent into Gravelly Run, a tributary of the James River and Chesapeake Bay Watershed.

2. Measurement & Control Technologies: Essential Tools For Sustainable Water And Wastewater Operations 6/25/2025

   Accurate measurement and control technologies are essential for achieving sustainability in water and wastewater operations by reducing energy use, minimizing losses, and optimizing chemical dosing.

3. The Most Cost Effective Disinfection Alternative For A Wastewater Plant To Meet Regulatory Requirements 2/10/2016

   The Valley East Wastewater Treatment Plant (Sudbury, Ontario, Canada) hired an engineering firm to evaluate three disinfection options including chlorination followed by dechlorination, ultraviolet (UV) light irradiation and VigorOx WWT II. Read the full case study to learn more.

4. Design Considerations For Packaged MBR Systems 6/22/2020

   Applying Membrane Bioreactors (MBR) in lieu of conventional activated sludge systems delivers higher effluent quality while eliminating secondary clarification processes. These systems incorporate flat-sheet or hollow-fiber membranes with pore sizes measured in micrometers or nanometers, which allow for complete retention of solids inside the treatment system.

5. Electroplating 1 (CrVI, Ni, Zn, Cu) 1/27/2016

   XXXX Plating Company operates a decorative plating shop in Los Angeles, Ca., doing finishes in nickel, copper, and chromium.

6. Sulzer Delivers Pumps For The Largest Water Construction Project In Europe 6/19/2023

   Read about a project that comprises three reservoirs, two rainwater treatment plants, and three pumping stations. 

7. Failing Lagoon System Gets New Life From MBR Retrofit 1/15/2012
   The Leoni Township’s wastewater treatment plant (WWTP) serves thirteen communities across three counties including the Michigan Speedway complex.
8. SDOX Technology Mitigates Sulfide Production By Promoting Aerobic Environment 2/2/2021

   The Plant’s wastewater treatment facility uses four, covered anaerobic lagoons to manage BOD, pretreating wastewater prior to sending the effluent to a pumping station which directs the wastewater into the municipal collection system for final treatment at the City’s wastewater treatment plant. Read more to learn how the company used hydrogen peroxide and a catalyst to maintain an aerobic environment but was unable to adequately mitigate the odor from the facility’s wastewater.

9. DELUMPER® LP Crusher Improves Cocoa Butter Processing 11/29/2020

   Chef Rubber, based in Las Vegas, Nevada, is a manufacturer and distributor of specialty supplies for chefs and well-known confectioners. The products include silicones, molds, colorants and colored cocoa butter. These unique tools are widely used by artisan chefs to create edible works of art for special events, competitions and other artistic applications.

10. Our Screens Work Great! Now What? (Part 3 Of 3) 9/22/2016

    This is the third installment of a three-part series exploring headworks screening problems and solutions. In this installment we will explore solids removal options for headworks facilities.
