Drinking Water Case Studies and White Papers

  1. Addressing Fouling Challenges In Desalination With Prefiltration 3/19/2024

    Pre-filtration is the first line of defense against fouling and is a critical part of the overall desalination process. These systems remove solids that can compromise delicate RO membranes.

  2. Why A Little Knowledge About Sensors Can Be A Dangerous Thing 6/4/2014

    Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

  3. How To Use Water Quality Monitoring To Increase Operational Efficiency 11/12/2024

    When properly utilized, water quality monitoring can reduce costs, aid in resource allocation, and ensure consistent regulatory compliance in a number of ways.

  4. Evaluation And Optimization Of Clean-In-Place Using Ozone 8/15/2018

    A chemical company which specializes in Clean-In-Place (CIP) systems, contacted Mazzei to discuss the use of ozone as an alternative to peracetic acid sanitation or heat sterilization at their customers’ plants.

  5. Successful Piloting Of UV Advanced Oxidation On Long Island For 1,4-dioxane Treatment 12/16/2020

    The New York State Department of Health has recognized the ultraviolet advanced oxidation process (UV AOP) as a treatment solution for 1,4-dioxane. For water providers located in Nassau County on Long Island, it was necessary to pilot UV AOP technology at the various wells requiring treatment in order to confirm treatment efficacy and obtain state approval.

  6. Mannheim Water Treatment Plant Upgrades to Sidestream Injection 4/14/2023

    Learn why Mannheim Water Treatment Plant's fine bubble diffusers were replaced with sidestream injection systems comprised of four skid-mounted venturi injectors, followed by four basin nozzle manifolds. 

  7. Defending Against Saltwater Intrusion 7/16/2019

    Are “ghost forests” a sign of things to come? Rising sea levels and superstorm tidal surges are already impacting coastal areas, with rising salinity levels affecting some drinking water sources. Coastal water utilities are not the only ones that have to worry about salinity, however, as high concentrations of winter storm road treatments, gas drilling, and mining can also generate elevated salinity levels in surface water sources.

  8. Case Study: Deuel Vocational Institution (DVI) ZLD Drinking Water Treatment System, Tracy, CA 12/6/2009

    A study was conducted by an environmental engineering firm to design a suitable treatment system for the groundwater currently used as the potable water supply for DVI. Reverse Osmosis (RO) was determined to be an effective technology in meeting the applicable standards for water quality.

  9. Recognized Results Based On Quality Assurance And Quality Control 5/11/2016

    Responsibility for analysis results lies with the users themselves or their supervisors. Both are therefore liable for any incorrect interpretations and decisions that are made as a consequence of incorrect data.

  10. Tank Shark® Active Tank Mixing Proven To Be Superior To Dedicated Tank Inlet/Outlet Design 7/10/2018

    San Jose Water Company (SJWC) provides drinking water for over a million people in the greater San Jose Metropolitan region and is a recognized leader in drinking water treatment and distribution system water quality management. With over 90 water storage facilities in service, planned maintenance and rehabilitation of capital assets is a key component of SJWC’s CIP program.
