Corrosion Threatening Your Water System? Here’s What You Need to Know

Corrosion is an unavoidable natural process, but when left unchecked, it can lead to serious damage in water systems—causing red water complaints, pinhole leaks, scale buildup, and even costly infrastructure failures. Whether it’s uniform corrosion thinning metal surfaces or pitting corrosion compromising pipes and tanks, every water system is at risk.

But corrosion control is possible. The right blended phosphate solution can help reduce lead leaching, extend system life, and improve water quality—but not all phosphate blends are the same.

The Key to Effective Water Treatment: Understanding Blended Phosphates

The most successful water treatment programs today rely on blended poly/orthophosphates to control corrosion, scale, iron, and manganese, making them essential for municipal water systems. But not all phosphate blends are created equal. Choosing the right formulation is critical to ensuring water quality, system longevity, and public safety.

What makes AQUADENE blended phosphate products different? How do they work at the molecular level to prevent scale buildup, reduce corrosion, and improve overall system performance?

Phenol Problem Solved at Wastewater Facility

An industrial user of phenolic resins and organic dyes that processes approximately 40,000 gallons of wastewater per day. The phenol concentrations can be as high as 7,000 mg/L. The phenol levels must be reduced to <50 mg/L prior to discharge.

The facility operates 24 hours per day and seven days per week processing a tremendous amount of phenolic resins. The high resin usage requires the facility to clean phenolic resin containers daily for reuse.

Exceeding EtO Emissions Compliance Standards

Meeting the EPA Subpart-O NESHAP regulations for ethylene oxide (EtO) emissions requires abatement systems to achieve up to 99.99% destruction removal efficiency (DRE)—a challenge when legacy monitoring systems lack the sensitivity to accurately measure compliance.

Together, Carus and Picarro have demonstrated that CARULITE 500 catalyst surpasses compliance thresholds, achieving an incredible 99.99988% DRE—far exceeding regulatory requirements. Backed by Picarro’s advanced emissions monitoring technology, this solution provides the trusted, real-time data needed to ensure compliance, efficiency, and environmental responsibility.

Optimize Radium Removal with Permanganate Treatment

Municipal Drinking Water Treatment for Radium Removal Technical Brief 

Optimize Radium Removal with Permanganate Treatment

Meeting the National Primary Drinking Water Regulations for Radium 226 & 228 (MCL of 5 pCi/L) and gross alpha emitters (MCL of 15 pCi/L) requires effective treatment strategies. CAIROX^® potassium permanganate or CARUSOL^® liquid permanganate, combined with manganese sulfate, forms Hydrous Manganese Oxides (HMOs)—high-surface-area compounds that effectively adsorb radium.

Sulfide and Corrosion Control

Kootenai-Ponderay Sewar District located near Sandpoint, Idaho, was trying to control hydrogen sulfide corrosion and odor at two lift stations and several manholes. The source of the problems was from a pressure sewer line that was being discharged into a gravity line below a manhole. The pressure sewer line consists of discharge from a STEP System (septic tank effluent pump). It was determined that the best point for applying odor control chemical was at the injection station located over a valve box of the pressure line.
