Industrial water systems require a constant source of fresh and clean water daily. If left untreated, water will foster bacteria and algae growth in a short amount of time whether it's in your factory, cooling tower or process equipment. TCCA granular is just one of several media that can be used for shock disinfection. The media is dumped into the water source and will slowly release chlorine as it reacts with the water to kill off unwanted organisms. The tcca granular performs well in large systems that have high flow rates and variable water quality. TCCA media is very common with many operators because it's easy to apply and sees quick results without too many steps. It can be used for cooling tower treatment by adding the media during blowdown cycles which will help maintain clear water and reduce odors.

Shock Treatment Protocols: Using TCCA Granules for Algae Bloom Control

Growing algae in a system can make a system green, stinky and unbalanced. This typically happens on cooling towers, storage tanks or open atmosphere circulating systems where there are nutrients present and sunlight. The tcca 90 granular shock treatment would most likely be used in this situation to get things back to normal. Shock treatment is simply adding a higher dosage of disinfectant for a short period of time to quickly shock out any algae and bacteria. Most operators will test the amount of water they have first using TCCA granular. This allows you to not overshoot or waste product. Then mix the granules needed with a bucket of clean water and pour it into the system. This allows you to distribute it evenly throughout the system rather than dumping it in one area. One situation was with a small manufacturing facility cooling tower. The operator noticed there were some green spots starting to show on the walls of the basin and cooling efficiency was down. After briefly stopping circulation they added a predetermined shock dosage of TCCA solution. The water started turning clear within a few hours. The system was much cleaner after one full turn over of the system and there was less algae growth over the next several days. Typically when shocking the water will run to allow the chemical to get to every aspect of the system. The system will sometimes circulate all night with some people. Operators will then test the chlorine levels and look to see if there is any remaining cloudiness. If there is, the system can be shocked again or if need be a lighter dose can be used. Something to watch out for when shocking is adding too much chemical. You don't want to stress the system too much or the water balance. Operating professionals stressfully observe this when shocking systems. Filters and strainers are usually cleaned after shocking as well since you will loosen the algae that will find its way into your filters and strainers.

Dosage Calculator: Achieving 5ppm Free Chlorine in Large-Volume Tanks

For proper chlorination, you must first know the dimensions of your large water storage. The normal level one tries to maintain is 5 ppm of free chlorine. Five ppm is not too hard on the system if used correctly and is effective against bacteria and algae growth. Dosage is easy to calculate and eliminates guessing and erratic water conditions. A good way to start is by understanding what 5 ppm means. It equals 5 milligrams of chlorine of water. The first step would therefore be always to know the total volume of the tank. As soon as that is understood all the rest is a simple calculation. As an example, when there is 100,000 liters of water in a tank, you multiply 100,000 by 5 mg. That contains 500,000 mg of chlorine required. This is 500 grams of chlorine. The tcca granular is commonly the source, so you also need to consider the chlorine strength of this material, which is not 100%. That is why operators tend to change the last figure a little bit more to be closer to reality. In practice, in an actual workplace, such as a food processing plant, the dose is usually mixed into a mixing bucket first. The granules of TCCA are completely dissolved and then poured into the tank. This aids in dispersing the chlorine rather than falling on the ground in a single location. The water is then allowed to circulate after dosing in order to ensure that the chlorine reaches all corners of the system. Free chlorine is measured after approximately 30 minutes to a couple of hours by water testing strips or a digital meter. In case the reading is less than 5 ppm, then small top-up is increased rather than redoing the entire calculation. This gradual adaptation will prevent abrupt shifts of water quality. The rate at which chlorine is used up can also depend on temperature, organic load and the condition of the tank. Tanks that contain a higher amount of dirt or algae might require a little bit more attention when dosing. Scheduled tests ensure that one does not add unnecessary chemicals by being near the desired mark. This routine is stable and this contributes to the safety, cleanliness and manageability of large systems over time.

Storage Best Practices: Preventing Hydrolysis in Humid Climates

In humid areas, storing granular TCCA requires extra care. Humidity in the air can slowly affect the stability of the product. This process is called hydrolysis which is when the product begins to react to water vapor prior to usage. When this happens, the potency lessens and the granules will not perform their task when disinfecting. The initial consideration would be to ensure that the product is kept dry at all times. Storage rooms must be closed, cool and not in direct sunlight. Concrete floor is superior to a soil base since it minimizes the amount of moisture that goes up into the ground. Most operators put pallets beneath the bags or drums in order to allow the air to pass beneath them to eliminate wet spots. Packaging also matters. When a bag has been opened, it should not be loosely tied. The help of airtight containers or closed plastic drums retards the appearance of moisture. Where there is a high level of humidity, other facilities also bag the product twice or they apply moisture-barrier liners to provide an extra layer of protection. A real life example is a water treatment plant near the coast where TCCA was kept in a simple storage shed. It was observed that during the rainy season, workers were experiencing clumping of the granules and reduced chlorine outcomes when it was time to dose. A few weeks after changing to sealed containers with the addition of simple dehumidifier packs in the storage area, the problem was resolved. Airflow control is also beneficial. Ventilation will help in eliminating trapped humid air, but it must not allow wet air to enter. Most operators have small exhaust fans which operate during the day but which are closed during heavy rains. Care should also be taken to ensure that TCCA is not in contact with such chemicals as acids, alkalis, or any other chemical that can react with chlorine compounds. Placing incompatible materials together in the same space would pose risk and reduce shelf life. Inspection is a habit that is easy to practice and can be very effective. Examining the presence of clumps, color differences or strange smell is used to detect early signs of moisture damage. It is also handy in terms of stock rotation, and the older batches are used first to ensure that nothing remains too long. These few steps can make TCCA granular remain longer in place even in hot and humid conditions and is more consistently used in water systems.
