MIOX Hypochlorite Generators replace Chlorine Gas for Wastewater Treatment

MIOX is pleased to announce that we have been selected as the preferred technology to replace chlorine gas used in the final disinfection of wastewater from the treatment plant in Tuxtla City, Mexico which is operated by TICSA.  In conjunction with Veolia Mexico, the MIOX on-site sodium hypochlorite chlorine generator system was chosen over competing technologies to improve safety at the facility.

The Tuxtla City wastewater plant is surrounded by residential neighborhoods and concerns over long-term safety drove TICSA to select a safer solution that was also economical.  The ability to use salt to generate chlorine avoids transporting hazardous chemicals through the City on the way to the plant. The system should be operating by the summer of 2015.

The project scope includes two MIOX RIO H4 on-site generators.  This equipment produces up to 800 pounds per day sodium hypochlorite and will disinfect wastewater for over 500,000 residents in Tuxtla City, Mexico.  MIOX sodium hypochlorite generators are designed to produce the absolute lowest cost chlorine available on the market.  Many facilities are turning to MIOX HYPO systems for safety, economic, and process benefits.Two (2) MIOX RIO H4 Chlorine Generators

WaterOnline Radio Podcast on MIOX Water Treatment Chemical Technology Innovation & Advanced Oxidation Process


CLICK TO LISTEN “MIOX Technology Innovation & Emerging iAO Chemistry”

During AWWA‘s Annual Conference and Exposition (ACE13) on June 9 – 13, MIOX’s Tom Muilenberg sat down at VertMarket’s Water Online booth to discuss the benefits of MIOX on-site chemical generation and emerging advanced oxidation process (iAO) during a live radio podcast.

Tom discussed not only an overview of MIOX chemistries, but also the various applications of MIOX on-site generators and how they are economically beneficial for the companies using them.  The main benefits that Tom mentioned include enhanced safety, increased efficiency for disinfection, easy to handle and operate, and a lower cost than other solutions.

City of Martindale, Texas – Membrane Pretreatment

Martindale photo2

My MIOX: SAL 80 Mixed Oxidant System City: Martindale
Company Name: Martindale Water Supply Corporation State: Texas
Name: Steve Fonville Country: UNITED STATES
Title: General Manager Application: Potable Water
MY MIOX EXPERIENCE: The Martindale Water Supply Corporation is located on the San Marcos River, thirty miles south of Austin, Texas, in Martindale, population about 3,000. The Corporation utilizes ground water from two alluvial wells. The Corporation completely rebuilt their water treatment system in 2000, converting to membrane filtration. The new treatment system consists of pre-chlorination, pre-filtration, ultra filtration using a Koch HF -26 membrane cartridge skid, ending in clear well storage. In order to reduce algae formation in our treatment system and to achieve the required chlorine residual in the distribution system we use a 2000 model SAL 80 MIOX system. Martindale WSC has been using the same SAL 80 for eleven continuous years.

The MIOX disinfectant solution has proven very compatible with the Koch hollow fiber filters. Our first set of filters lasted twice the expected lifetime of five years. Clean filters require less cleaning cycles, less down-time. We’ve always received excellent service from MIOX whenever parts or technical assistance are needed. The SAL 80 has been quite reliable, operating now for 25,460 hours. I’ve replaced three cells, one brine pump, and one power supply.

The main reason I initially selected MIOX for our needs is safety. I have dealt with gas chlorine for many years. Our water treatment plant is located in the center of the town. Private residences are within 100 feet. Using MIOX allowed for the location of the disinfection generation system to be safely located in the same building housing our main office, laboratory/SCADA control room, and ultra-filtration skid.

I have been very pleased with the performance and reliability of the SAL 80 system. I would recommend MIOX systems for consideration whenever considering water disinfection systems.

MIOX at NIPSCO Power Plant


My MIOX: RIO M-5 City: Valparaiso
Company Name: Northern Indiana Public Service Company (NIPSCO) State: Indiana
Name: Paul Schrock Country: UNITED STATES
Title: Senior Chemist Application: Cooling Towers
MY MIOX EXPERIENCE: Disinfection of our Company’s generating station cooling tower waters has always been a critical priority and costly undertaking. NIPSCO has historically employed the simultaneous feed of various combinations of treatment chemicals in order to control the bio growth and hazardous bacteria species in these systems.Our Company was looking for a more cost effective treatment regimen that would yield better bio-control results. We thought that we should be getting more “bang for our buck” with the multi-chemical treatment regimen we were using. Although we were aware that onsite oxidant generator technology existed, we were not aware of a particular manufacturer’s ability to provide a reliable, long-term machine that could produce the volume and quality of oxidant product that we need on a daily basis. Fortunately, our eyes were opened by the MIOX Corporation in late 2008 … they reportedly had a quality product that would meet our needs.After much discussion, evaluation, and training on the product, we decided to purchase and install a “RIO M-5,” 300 LB/Day FAC (9,000 gallons per day of 0.4% mixed oxidant solution) system at one of our large cooling towers. Due to the stringent provisions of our environmental discharge permit, the entire system needed to be fully automated in order to ensure that violations of the permit would be virtually impossible. The entire MIOX system was very conducive to automation and has now been INSERV on a 24-7 basis since April, 2010 – yielding equal, if not better, disinfection performance results as before.

Reducing our treatment regimen from 3 different products down to a single mixed oxidant product (generated on site) has resulted in substantial treatment chemical and labor cost savings. We are pleased that we were able to find a top-notch company (MIOX) that actually produced an equally impressive product, and may look to install additional similar systems at other cooling tower locations.
