Wastewater Treatment Case Studies and White Papers

  1. Finescreen Helps Plant Operate On Cruise Control
    4/29/2016

    As part of the new facility for the City of Clinton, the plant installed a new finescreen as an integral part of the operations. What they discovered was not only a reliable and durable technology but the automated feature of the system was transformational for plant operations. Read what they have to say.

  2. CeraQ Ceramic Membranes Provide Robust Solution For Automotive Parts Manufacturing
    3/23/2016

    An automotive parts manufacturing plant was using a polymeric membrane to remove oil from water it used to rinse parts. The rinse water contained between 6% and 7% oil and the customer wanted to remove >95% of the oil from the water so the water could be reused in the plant.

  3. Oxygen Removal From The Feedwater Of A Central District Heating System
    9/17/2018

    Central district heating systems have gained attention in recent years because they can be more efficient than localized boiler units. The efficiency of district heating is usually due to power generation plants being able to produce heat and electricity simultaneously. District heating also helps prevent pollution by using advanced flue gas cleaning techniques.

  4. Rapid Custom Parts Delivery Gets Critical Pump Back Online
    3/23/2009

    The North Tahoe Public Utility District (NTPUD) serves residents and vacationers in the Lake Tahoe area. Vaughan Co. provided a 50 HP, 1750-RPM model PE4P6CS-118 vertical pedestal chopper pump for the Carnelian Bay Pump Station to replace an existing pedestal pump, which was having difficulty with ragging. Vaughan Company

  5. UV System Saves Energy And Reduces Maintenance
    2/21/2018

    After a 17-year run, a plant’s UV disinfection system was limping toward the finish line. The city needed to identify a replacement UV system that fit into the same channel, offered lower power consumption, and contained a practical ease of maintenance to reduce the amount of labor consumed on the equipment. The new system requires dramatically less power to run while simultaneously streamlining upkeep.

  6. Rumors, Half-Truths, And Truths About Temperature And pH
    4/6/2015

    A few months ago I received a call from an angry user who was using one of our differential probes and a controller. Embedded in the probe is a thermistor that measures temperature.

  7. Innovative Use Of Dissolved Air Flotation With Biosorption As Primary Treatment To Approach Energy Neutrality In WWTP’s
    6/1/2016

    This paper presents two types of DAF applications together with biosorption (the “Captivator system”) as primary treatments. In one case, the Captivator system is the sole primary treatment for a new plant installation and helps to gain 65 percent more biogas while requiring only 44 percent of aeration for COD oxidation, compared to a conventional process.

  8. Measuring pH And Its Role In Corrosion Control
    9/19/2018

    Corrosion control has always been a priority for distributing safe drinking water throughout the world’s networks of pipeline. This has become all the more critical following the outrageous lead poisoning revelations in Flint, MI — an incident caused directly by corrosion of the city’s lead-based infrastructure.

  9. Protecting Our Water – Keep Chemicals In The Tank
    2/12/2014

    Leaking or overfilled tanks can cause environmental problems, contaminate drinking water, and cost a company millions of dollars. Proper instrumentation, monitoring and control can prevent these problems. By Bill Sholette, Level Products Business Manager, and Ricardo Chavez, Solutions Business Manager, Endress+Hauser

  10. Case Study: Prosonic S Provides Reliable Control Of Filtration For Raw Sewage Water
    1/24/2011

    In the inlet of the plant, the raw sewage water is filtered through 3 automated systems. The filtration systems are equipped with an endless mesh, which captures the solid materials. By Endress+Hauser, Inc.
