The hallmark of the company’s approach to microbial control has been the inclusion of equipment rental, maintenance services and outcome guarantees in its chemical offering, which highlights PeroxyChem’s depth of technical and engineering expertise.
In 2013, PeroxyChem launched a new formulation specifically designed for municipal wastewater disinfection registered as VigorOx® WWT II. This formulation, which contains 15% peracetic acid and 23% hydrogen peroxide, improves effectiveness and minimizes BOD impact on effluent. VigorOx WWT II has been applied as primary disinfectant in numerous wastewater treatment plants in North America to eliminate concerns associated with chlorination – safety, toxicity, byproduct formation and cost.
The City of Hannibal, Missouri, sought a cost effective disinfection technology to meet upcoming National Pollutant Discharge Elimination System (NPDES) permit. Read the full case brief to learn how the full-scale test confirmed that VigorOx WWT II is a cost effective solution for this plant to achieve the disinfection goals.
The City of St. Helena, CA, uses a municipal wastewater system with aerated lagoon and an average flow rate of 0.5 million gallons per day. The performance of existing chlorination process becomes less effective during some periods of summer and fall months, and the city sought a cost effective technology that could provide more stable disinfection performance over a broad range of pH conditions and could easily retrofit the existing system.
The Valley East Wastewater Treatment Plant (Sudbury, Ontario, Canada) hired an engineering firm to evaluate three disinfection options including chlorination followed by dechlorination, ultraviolet (UV) light irradiation and VigorOx WWT II. Read the full case study to learn more.
Wastewater treatment plants are required to disinfect effluent prior to discharge in order to destroy any pathogenic organisms present and minimize public health concerns.
Accurate measurement of peracetic acid (PAA) in wastewater is critical for the proper dosing of PAA to meet target microbial reduction targets and to ascertain the concentration of PAA in the plant effluent to meet local regulatory water quality standards. This edition of Wastewater Disinfection Forum discusses the current state of the art in the measurement of PAA in municipal wastewater.
This article discusses the discharge limit of peracetic acid (PAA) into the environment and the incorporation of dilution factors in the assessment of site-specific, risk-based residual PAA concentration in wastewater effluents.
VigorOx® WWT II wastewater disinfection technology is a very effective technology for wastewater disinfection. Its combination of efficacy for microbial kill, ease of use and low impact on the environment make it an ideal choice as an alternative to chlorine disinfection.
Welcome to the first edition of Disinfection Digest, a forum to share experiences using PeroxyChem’s VigorOx WWT II wastewater disinfection technology.
This edition of Disinfection Digest discusses the benefit of using VigorOx WWT II for wastewater disinfection to address concerns or compliance issues with regards to disinfectant by-products (DBPs) and the implications to wastewater utilities.
