Choosing the wrong industrial water treatment system might do more than just cause poor water quality. It could mean frequent shutdowns, quick membrane fouling, failed production audits or a system that just can’t keep up with daily demand. And this nearly always comes down to one core problem. The system was evaluated for capacity, and…
You measure your feed water and the number comes back high — now the real question is why. The high Silt Density Index (SDI) reading is among the most evident early warning indicators that reverse Osmosis (RO) process is headed towards membrane fouling, a higher differential pressure and frequently chemically cleaned. Before troubleshooting can begin…
As wastewater discharge requirements become stricter, many treatment plants are facing the same practical problem: how to remove more nitrogen and phosphorus without building larger tanks or significantly increasing operating costs. At the same time, conventional activated sludge systems can require substantial aeration, tank volume, and sludge handling. Biofilters offer another approach. By growing microorganisms…
RO membranes are quite good at eliminating dissolved salts, organics and other pollutants, but they are also very sensitive to what is in front of them. A poor mix of particles, minerals or chemical residues in the feed water can quickly foul or damage membranes, increasing operating costs and shortening membrane life. This guide walks through the…
A purified water or WFI system passes validation, sails through routine monitoring for months, and then — without warning — a single sample exceeds the action limit. QA opens an OOS investigation, production halts, and everyone asks the same question: how did a “compliant” system suddenly become a contamination risk? The reality is that pharmaceutical…
For an offshore oil platform, fresh water is not something that can be treated as a routine supply item. Personnel need water every day for drinking, cooking, washing, cleaning, and other basic operations, while the platform may be hundreds of miles from the nearest shore. If a supply vessel is delayed by bad weather, the…
If your cell lines show improbable growth or contamination or results that aren’t reproducible, the issue could be not with your process. It could be your water. Ultrapure water for cell culture requires a higher standard than lab-grade water. It has to be free of any endotoxins, RNase/DNase, and have a low concentration of dissolved…
Fresh water may not be as abundant as some people believe. Access to reliable supplies has become an issue for many parts of the world with growing populations, expanding businesses and irregular rainfall patterns. One approach to address this issue is a desalination system that processes salty or brackish water into treated freshwater. One of…
There’s no definitive answer for the frequency at which the ion exchange resin must be renewed, as it varies based on the hardness of the water, the flow rate, type of resin and system size. Softeners for household use typically regenerate every 2-7 days, whereas industrial systems might require periodic or even constant regeneration. We will break…
When comparing reverse osmosis (RO) systems, you will often come across capacity ratings such as 500 GPD, 1,000 GPD, or even 10,000 GPD. These numbers refer to the amount of water an RO membrane or system is rated to produce under specific operating conditions. GPD means Gallons Per Day, and it is one of the…
