  1. How Does a Commercial Reverse Osmosis System Work?

    Leave a Comment

    Reverse osmosis is a technology that treats water to remove salt, chlorine, sediment, and other impurities. During the reverse osmosis process, pressure is used to pass source water through a thin membrane. The semipermeable membrane allows the water through while catching the solids and bigger molecules like ionized dissolved salts and other contaminants. A wide range of industries and applications rely on commercial reverse osmosis systems to deliver highly purified water when required.

    Commercial RO Process

    Commercial RO Process

    The commercial reverse osmosis (RO) process works by reversing the principle of osmosis, which is the natural tendency of water with dissolved salts to pass through a membrane from lower salt concentration to higher salt concentration. 

    In an RO system, pressure is utilized to overcome natural osmotic pressure, forcing the source water with its dissolved salts and other contaminants through a semipermeable membrane. This membrane removes a high percentage of the impurities, resulting in highly purified water. The impurities and rejected salts concentrate collect above the membrane and are passed from the system for draining or further processing.

    While RO systems are most common in industrial processes, they function the same way and offer the same benefits when used commercially. Each commercial osmosis system is customized based on the desired quality of water and the type of raw water issues you have. Common industries that rely on commercial RO systems include beverage, food, dairy, pharmaceutical, and more.

    Benefits of Reverse Osmosis

    Many commercial operations rely on reverse osmosis due to its many advantages. As a water treatment process, reverse osmosis offers the following key benefits:
    Benefits Of Reverse Osmosis

    • Total dissolved solids reduction. The commercial reverse osmosis process is one of the only water treatment processes that offers total dissolved solids reduction. Although other water treatment methods boast this capability, they aren’t as efficient as reverse osmosis. 
    • Cost-effectiveness. Reverse osmosis is popular for various commercial operations due to its highly economical price point compared to other filtration methods. This enables companies to treat large amounts of water while staying comfortably within their budget.
    • Eco-friendliness. Reverse osmosis is relatively environmentally friendly compared to other water treatment methods. Reverse osmosis systems require less energy than thermal distillation methods since they don’t require energy generation. By reducing energy usage, a company can lower its carbon footprint, aid against global warming, and protect the environment.
    • Alkalinity and hardness removal. Reverse osmosis can effectively remove contaminants such as magnesium and calcium ions that create hard water. It can also prevent unwanted alkalinity by removing carbonate ions.

  2. Ultraviolet Disinfection in Municipal Water & Wastewater

    Ultraviolet Water Treatment

    The citizens in your community count on you to ensure that the water they drink is safe and the wastewater produced is treated effectively without issues that can cause environmental damage. Ensuring that your water and wastewater are free of contaminants and infectious agents is a must. Ultraviolet (UV) disinfection treatment has a wealth of benefits for municipal water and wastewater systems.

    UV Disinfection Services for Municipal Water & Wastewater

    Traditionally, the answer was to increase chlorine levels to increase disinfection power. However, allowable chlorine levels have been lowered as well due to concerns about discharging potentially dangerous chlorinated organic compounds. 

    These competing pressures can make it hard to reach the right balance. UV disinfection is an alternative that allows you to keep water clean and safe without worrying about excessive levels of chlorine-based disinfectants. In municipal water treatment, UV disinfection is typically the final step in a multi-stage treatment process to remove any remaining protozoa, bacteria, viruses, or other pathogens that may have a negative impact on public health.

    Ultraviolet light has been proven to destroy the reproductive capabilities of pathogens by damaging their RNA and DNA, effectively rendering microbes inactive and harmless. UV disinfection uses a wavelength between 250 and 270 nm for optimal disinfection. By configuring the system to provide the correct dose time, intensity, and configuration, water management officials can disable harmful pathogens without having to worry about excessive amounts of chlorine in the water.

    These systems typically use mercury arc lamps or amalgam lamps alongside a reactor, ballasts, and a control system. Together, they safely purify water without harmful chemicals.

    Benefits of UV Disinfection for Municipal and Wastewater 

    UV disinfection stands in stark contrast to other options like chlorine and chloramines. Citizens will often complain about the taste of both chlorine and chloramines in water. Additionally, some worry about the safety of chloramines for applications like home aquariums. UV disinfection offers a variety of benefits, including:

    • No toxicity. UV disinfection uses light to eliminate bacteria, viruses, protozoa, and other pathogens. This process adds nothing to the water and doesn’t impact the chemical composition, therefore leaving no by-products in the water that would otherwise have serious effects on public health.   
    • Eco-friendliness. Ultraviolet disinfection provides a significantly more sustainable option than chemical disinfection. There is no chemical discharge to worry about, allowing you to keep levels of chlorine well within allowable concentrations.
    • Affordability. UV disinfection systems are highly cost-effective and pay for themselves over time. Once the system is in place, it can run reliably with minimal maintenance for many years. 
    • Efficiency. This system works both rapidly and effectively. This means that even high-volume municipal water and wastewater systems can still operate cleanly and safely. 
    • Effectiveness. Since a number of protozoa are chlorine-resistant, UV is the far safer and more effective choice.

  3. Understanding Industrial Water Filtration

    Leave a Comment

    Water filtration is a critical aspect of many industrial operations. From process water to potable water, Reynolds Culligan’s industrial water filtration systems are engineered to enhance your operational quality and efficiency. To choose the right industrial water filtration system for your needs, it is important to understand what water filtration systems do, their benefits, and the applications for which they are used. 

    What is an Industrial Water Filtration System

    Industrial water filtration systems are used to remove foreign elements from raw water through a series of different filtration and disinfection processes. Each step of the process is critical for meeting industry standards and government regulations for water quality. Industrial water filtration systems typically incorporate the following processes:

    • Intake. Raw water is pumped into the filtration system using gravity or electrical pumps. The intake uses a grate to keep large objects from entering the system.
    • Clarification. The raw water is subject to a series of chemical treatments that encourage particles and other contaminants to coalesce into larger clumps. The coagulated matter can then be filtered out of the water using filters and screens.
    • Disinfection. Once the water has been clarified, it is treated with chemicals, exposed to UV radiation, and/or filtered through a fine membrane in order to eliminate microscopic contaminants, toxins, and pathogens. 
    • Ion Exchange. The disinfected water passes through a cation resin, which removes calcium and magnesium to soften the water
    • Distribution. Filtered water is recycled back into the system for process uses, released into the environment, or recycled into potable water systems, depending on system requirements and government regulations.

    Benefits of Industrial Water Filtration

    Industrial water filtration systems offer a number of benefits for commercial, industrial, and municipal operations. Some key benefits of using Reynolds Culligan industrial water filtration systems are:
