41. MD3 CHEM-FEED® Multi-Diaphragm Metering Pump 9/18/2024

    The MD3 Multi-Diaphragm Metering Pump delivers smooth, continuous chemical feed even when injecting chemicals that off-gas like Peracetic Acid and Sodium Hypochlorite.  The cutting-edge Hyperdrive Technology allows for alternating pumping action between two diaphragms: when one diaphragm is in the suction phase, the other is in the discharge, resulting in a smooth chemical feed profile and eliminating the chance of vapor lock and loss of prime.

42. How To Optimize Your DAF System With Air Dissolving Pumps 9/6/2024

    Despite their importance in modern wastewater applications, not all DAFs are created equal. Factors, such as the components that make up these systems, will influence how well they work and how long they last.

43. Disinfection 8/9/2024

    As the final step before treated wastewater leaves the plant, effective disinfection is extremely important to protect human health, and the maintenance of the environment. This process eliminates pathogenic organisms that cannot be removed by previous treatment steps and reduces the spread of pathogens in the natural ecosystem.

    USP’s current offerings include our unrivaled in-house CFD modeling expertise that can be used to optimize the injection, mixing and feed rates of PAA to meet the disinfection requirements of a facility. Also, launching later this year, is our OaSys iCT™ is a novel control approach that optimizes disinfection performance by calculating the optimal chemical dosage that accounts for sources of treatment variability in real time. Available for use with PAA or chlorine.

44. SulFeLox® 8/9/2024

    Hydrogen sulfide (H₂S) presents a significant challenge in wastewater management. Its foul odor and corrosive nature can severely damage infrastructure, leading to costly repairs. More importantly, H₂S poses substantial health risks, including respiratory issues and, at high concentrations, potentially lethal effects. Effective H₂S control is not just a regulatory requirement; it's essential for safeguarding infrastructure and public health.

    Our Solution:

    SulFeLox® is USP’s patented buffered iron solution for wastewater collection system sulfide control, with a hazard rating profile similar to nitrate (1-0-0).

45. WET WELL WIZARD Wastewater Collection System Aeration 7/26/2024

    Every modern town or city has a wastewater collection system of some type. The wastewater collection system is the conduit for used water, both sanitary and graywater (relatively clean, including stormwater), which initiates at the individual homes and businesses in the community. A primary part of the wastewater collection system is a number of “wet wells” that are used as wastewater collection points, or intercepts, from community neighborhoods. Often, lift stations, complete with large electric waste pumps, are used to keep the water moving to the city’s wastewater treatment plant.

46. Iron Salts 7/15/2024

    Iron salts are a proven technology for long-duration hydrogen sulfide control in collection system gravity and forcemains; solids processing units, solids transfer lines and anaerobic digesters. They have been used for over 30 years in hydrogen sulfide control applications and are a well understood technology.

47. Why Measuring Hydrogen Sulfide In Wastewater Matters 7/11/2024

    Hydrogen sulfide (H₂S) gas in wastewater environments is a familiar concern. But waiting until its odor is detected can be too late to exert as much control over it as desired. Fortunately, a new ability to monitor H₂S concentrations — in the liquid wastewater stream, in real time — is advantageous for wastewater professionals in terms of safety, cost, and consumer complaints. Here are four ways to capitalize on that capability.

48. Biosolids Odor And Corrosion Control 7/8/2024

    For more than 20 years, USP Technologies’ comprehensive biosolids odor and corrosion control solutions have been extremely effective at reducing sulfides and other odor causing compounds in municipal and industrial wastewater treatment systems.

49. GS1440 Sensor H2S 7/8/2024

    Water or air, measure H₂S where it matters – right at the source.

50. Achieving A Delicate Balance To Maintain RO Membranes 7/8/2024

    This application note explores the importance of maintaining a delicate balance in reverse osmosis systems to protect RO membranes.
