The Importance of RO System Data Collection Collected Data Maintaining records of operating data is necessary to monitor RO system performance. These records are usually kept on log sheets that can be designed for a specific system (such as RO). These are essential for both troubleshooting and possible warranty claims. The following data should be [...]

Determining Foulants & How to Clean Them - Part 2 Cleaning Biological, Or Organic, Fouling The first step is to remove biological fouling, which includes bacteria and organics. In order to do this, they must be digested. This can be done with a high pH and high temperature cleaning with a minimum of 2 hours [...]

Determining Foulants & How to Clean Them - Part 1 Determining Foulants Fouling can be caused by a few things. This can be from either particles like clay, organics and bacteria, or from inorganic deposits. Often times, it's a combination of many different foulants as they form layers on the surface of the membrane. The [...]

7 Common Causes of Membrane Fouling & Degradation Feed Water Considerations Fouling is a process during which continuous buildup of contributing deposits reduce the function and efficiency of the operating system. Membrane systems are mechanical and therefore subject to fouling on the surface. This fouling ultimately degrades the membranes. There are 3 main causes of [...]

When Should RO Membranes Be Cleaned? What To Look For Membranes need to be cleaned when either... differential pressure increases by 50% normalized flow drops by 10-15% salt rejection decreases at least 2% The key to knowing when membranes need to be cleaned is to consistently collect data with the start-up of your RO system [...]

What Are The 5 Stages of Water Treatment? THE IMPORTANCE OF WATER PURIFICATION The safety of drinking water is fully determined by water purification. Water must be tested to make sure that it meets the government guidelines in place to ensure safe drinking water. Meeting these standards is crucial to ensure water is properly purified [...]

Control of Odors in the Brewing & Food Processing Industries - Part 3 Previously, we discussed the problems with odors that often emanate from breweries and food processing plants as well as learning more about hydrogen sulfide, the common cause of these odor problems. Below, we discuss programs and solutions that can be used to [...]

Control of Odors in the Brewing & Food Processing Industries - Part 2 Hydrogen sulfide (H2S) is the most commonly known and prevalent odoriferous gas associated with wastewater treatment systems. In addition to being toxic and corrosive to delicate instrumentation and other metals, it has a characteristic rotten egg odor that is objectionable and disagreeable. [...]

Control of Odors in the Brewing & Food Processing Industries Hydrogen sulfide (H₂S), easily recognized by its rotten egg odor, is usually responsible for most of the odor problems associated with brewery and food processing wastewater treatment. Colorless, corrosive, heavier than air, and extremely toxic, its presence raises serious workplace health and safety concerns. Below, [...]

Organics Monitoring in Your Water System - Part 3 More Organics Monitoring Applications Organics monitoring solutions exist for a range of industrial, municipal and ultrapure water applications. Previously, we discussed boiler feed and steam condensate as well as drinking and source water. Here, we will discuss process water and wastewater. Process Water Water used in [...]

Organics Monitoring in Your Water System - Part 2 Monitoring Boiler Feed and Steam Condensate The formation of corrosive organic acids or fouling of boiler components can result in organic contamination in steam from natural occurring products organics, heat transfer or process chemicals Traditional means of controlling corrosion include monitoring for conductivity and pH called [...]

Organics Monitoring in Your Water System - Part 1 Monitoring Process Process water and steam condensate contamination include inorganic, biological, and organic components. Sources of organic contamination can include heat transfer fluids, process chemicals, and food & beverage products, as well as naturally evolving organics from surface and groundwater. If an excess of dissolved organic [...]
