Control of H2S (Sulfides) with Chlorine Dioxide

Hydrogen sulfide (H2S) is a toxic gas that can be produced naturally or from industrial activities such as oil and gas production, wastewater treatment, and pulp and paper manufacturing. H2S is highly corrosive and poses a serious threat to human health and the...

Controlling Algae With Chlorine Dioxide Water Treatment

Algae can be a lovely aesthetic feature of a pond, or even a supplement for protein in humans, but it also can prove irksome when overgrowth occurs. Indeed, the plant isn’t always a beautiful feature of nature, but can be bothersome and potentially even dangerous. As...

Iron (Fe) Removal with Chlorine Dioxide

Iron (Fe) is a naturally occurring element that is often found in water sources, particularly in groundwater. While small amounts of iron in water are not harmful to human health, high levels of iron can cause a variety of problems, including discoloration of water,...

Why are biocides added to cooling tower water?

Cooling towers are an essential component of many industrial processes, providing efficient heat exchange and cooling of water systems. However, cooling towers are also a breeding ground for harmful microorganisms, such as bacteria, viruses, and fungi. These...

Johns Hopkins Health System’s Use of Chlorine Dioxide

The Legionella Problem   Legionella pneumonia carries a mortality rate of 40% and can be spread in healthcare facilities like hospitals through water supplies. Because of this, hospitals are always looking for the most effective methods for treating their water...

What is Biofilm and Why Should You Care?

What is Biofilm? Have you ever been hiking and walked across a stream that had rocks or boulders under the water? If you have, then you know that all-too familiar feeling of a slimy consistency that builds up on these rocks. Especially if you have slipped into the...

What are the Best Chemicals for Cooling Tower Treatments?

Cooling towers are immensely efficient, cost-effective tools for controlling temperature in industrial sized buildings. The size of the towers alone can make the task of cleaning them feel daunting, but the US Occupational Safety and Health Administration (OSHA)...

Chlorine Dioxide Is Not Bleach

Kristen Brown of Bloomberg recently published a news article titled “The Church That Helped Bleach Go Viral As A Fake Cure”, and we at PureLine would like to set the record straight: chlorine dioxide is not what is commonly referred to as bleach! Mineral Miracle...

Maintaining the clean and efficient operation of your boilers is important. A deposit of just 1/16 inch can result in an efficiency loss of up to 20%. Heavier deposits can lead to tube overheating and failure. PureLine offers a variety of boiler water-treating compounds designed to help control oxygen corrosion, scale, and sludge deposits, condensate corrosion, and more.

PureLine also offers chlorine dioxide water treatment products to help maintain pre-treatment equipment such as water softeners and reverse osmosis units. Water softener resin can become fouled with iron or manganese. Resin fouling reduces the capacity of the softener and results in high feed-water hardness and boiler deposits. Reverse osmosis membranes can become fouled with mineral scales or microbiological growth. Membrane fouling leads to reduced capacity, more frequent cleanings, and membrane deterioration. Your PureLine representative can choose the right program for you.


Our cooling water deposit and corrosion control programs utilize the most up-to-date technologies to help our customers operate efficiently. Our expertise in biofilm control will help minimize the potential for problems related to microorganisms, including fouling, deposits, corrosion, and disease.


PureLine offers a complete line of wastewater and chlorine dioxide water treatment products and services. Our field technical specialists work with customers to optimize and improve their influent or effluent water quality. Whether it’s a reduction of turbidity, BOD, COD, or odor, improving sludge dewatering, or removing heavy metals, PureLine can help achieve your discharge, disposal, and regulatory goals.


Water storage ponds can be plagued with algae, sulfides from putrefaction, and undesirable contaminants like soluble iron and soluble organics. Eliminating algae and rotting bottoms is vitally important for the long-term health of a pond. These contaminants can cause odor problems and reduce the functional volume of the pond. PureLine provides chemical oxidizers and mechanical applications technologies to rid ponds of algae, rotting egg odors, soluble metals, and organics that contribute to elevated COD numbers. All of this without concern for halogenating these organics, forming bio-recalcitrant, toxic compounds.


PureLine understands and uses all of the chemical and mechanical tools common to the liquids/solids separation industry from flotation cells, media and membrane filters, and cyclonic technologies. Our expertise is in solutions development that meet operational and financial objectives.

PureLine technical champions include more than 100 years in water and water solids, and oil/water management. Collectively we understand the science and technology in the targeted disruption of interfacial tensions which resist desired separations. Whether your application is forming gels, removing oil and/or suspended solids from process streams, removing or destroying soluble organics, PureLine has the knowledge and the determination required to provide financially viable solutions.

Water and wastewater processing for Mining, Steel, HPI/CPI, and other secondary and tertiary industries, such as Pharma and the destruction of complex organics; PureLine can and wants to help.

Our solutions are mechanical and chemical with an emphasis on the mechanical to minimize consumables in the operating environment.


Reverse Osmosis (RO) technology is an increasingly popular method used to provide high purity water for industrial processes, potable water, waste treatment, water reclamation, and many other applications. In the process of producing high purity water, RO systems concentrate ions and other contaminants. As a result, the brine concentrate and the softened water can experience scaling, deposition, microbiological fouling, and membrane degradation.

PureLine’s product line includes inhibitors for the range of problems in the Reverse Osmosis system, including chlorine dioxide which, unlike chlorine, does not attack the membranes. PureLine’s experience and technical support laboratory provide the expertise required to identify problems and make the right recommendations to improve system integrity and performance.

Chlorine dioxide, at low dosages, will clean up and keep RO membranes clean from biofouling. Unlike chlorine, chlorine dioxide at low dosages will not damage the membranes, eliminating the need for “dechlorination” programs.


PureLine views equipment solutions as more than simply a means to ensure that chemicals are fed into a system. We consider a number of factors: safety, design, efficiency, communications, and environmental impact, to be important when we engineer a viable equipment solution for a customer’s facility.

Of course, a major part of any successful water treatment program is quality feed and control equipment. Without such properly installed and configured equipment, it is not possible to properly dispense the chemicals or to control the system parameters that are designed to protect the water system.

We at PureLine offer the newest technologies available in water treatment controls, storage, testing, and feed equipment. Custom water treatment control and feed system design and implementation assistance is available from our team of engineers as part of a customer’s total water treatment program.


If you are experiencing operational deficiencies, need to increase throughput, experiencing environment discharge shortfalls, condensate system corrosion failures or any challenge associated with water systems operations, design capability, chemical treatment programs…

PureLine offers an experienced, expert staff of engineers, chemists, and technicians to partner with our clients in designing, implementing, and supporting custom solutions focused on the unique problems they face. Offering a single source for all of your treatment needs, and a willingness to work with your existing water treatment company are just a couple reasons a lifelong partnership with PureLine has such great value.
