On-Site Chemical Generators, MIOX 101 Webinar

Newsletter_Webinar_3

MIOX on-site chemical generation delivers smarter water disinfection solutions to increase performance, ROI, safety and revenue. But did you know that MIOX systems are very easy to operate and designed for high efficiency, low lifecycle cost, durability and reliability?

Let me show you how easy it is to generate disinfection chemistry at your site. Eliminate the transportation, storage and handling of hazardous chemicals AND generate a more effective disinfectant.

MIOX Chemistries are replacing delivered bulk chemicals in many industries across the globe: Municipal Drinking & Wastewater, Industrial Wastewater Treatment & Reuse, Swimming Pools & Spas, Hospital Secondary Disinfection, Food & Beverage Processing, Livestock Watering & Sanitation Solutions, Oil & Gas Water Treatment & ReuseCooling Tower Water Treatment.

Let’s start with the basics and then we’ll open the forum up for Q&A. In this webinar, you will receive a virtual tour of a MIOX on-site chemical generator (OSG) and learn about:

  • Key components of the MIOX OSG
  • MIOX electrolytic cell & flow path
  • Ability to meet disinfection challenges of any size

Hydrogen Sulfide Removal

Common chemical oxidation methods for hydrogen sulfide (H2S), an odor causing chemical formed by the action of anaerobic bacteria in water and wastewater systems include chlorine, hydrogen peroxide and ozone.  Case studies and laboratory studies performed to date show that Mixed Oxidant Solution (MOS) tends to speed reaction rates or drive oxidation reactions to completion compared to sodium hypochlorite.

The oxidation of H2S is a two part reaction in which elemental sulfur (S0 ) is an intermediate before reaching the fully oxidized state as sulfuric acid (H2SO4).  S0 is a solid that must be filtered in municipal applications, so if the reaction cannot be driven to completion with hypochlorite, additional capital equipment must be purchased.   With sufficient dosing, MOS does not require a detention tank, filter system, and head can be maintained from the wells to distribution.

  1. Cl2 + H2S = 2HCl + S0  (reaction may stop here if the hypochlorite dose is not high enough)
  2. S0 + 3Cl2 + 4H2O = 6HCl + H2SO4

The combined reaction is:  H2S + 4Cl2 + 4H2O = 8HCl + H2SO4

MIOX and odor control in wastewater systems: In 2013, a MIOX MOS Zuni system replaced a bleach caustic chemical program in the trickling filter and scrubber system of a wastewater treatment plant in the state of Washington.   Since its installation, there have been no complaints from nearby neighbors concerning odors from the plant.  The MOS is also used to prevent ponding, or excessive growth of biological material in the media of the filter.  Since the introduction of the Zuni system, which uses only salt and power to generate the Mixed Oxidant Solution (MOS), the operators have ceased using the caustic, providing a both safety and cost advantage.  MIOX MOS was used also used to successfully replace hydrogen peroxide (H2O2) in a sewer collection system, decreasing the H2S concentrations from 15 mg/L to non-detectable.  Because of the distributed nature of the wastewater collection system, using a small OSG system that can be remotely monitored often provides operational flexibility.

MIOX and Advanced Oxidation Processes:  More recently, MOX’s on-site generators were used in combination with UV to produce hydroxyl radicals.  This process is called an Advanced Oxidation Process (AOP) and was used to remove MIB (2-methylisoborneol), an odor causing algal byproduct from the intake water at a large municipal facility in the United States.

Wastewater Reuse Treatment for Industrial Water Reuse at Hawaii WWTP

The Honouliuli Wastewater Treatment Plant (WWTP), located in Oahu, Hawaii, now utilizes four MIOX Vault H100 Self-Cleaning systems for wastewater reuse treatment.  The project was collaborated with MIOX exclusive partner, Parkson.  The 26 million gallons/day facility relies on MaximOS and other technologies to facilitate irrigation by the municipal government and supply process water for a power plants and oil refinery water.

The City and County of Honolulu owns and operates the Honouliuli WWTP, which is the regional wastewater treatment facility for the ‘Ewa district. The plant is located east of the former Naval Air Station Barbers Point and processes approximately 26 million gallons per day (mgd).
