How to Clean and Maintain Cooling Tower Fills Properly?

During the long-term use of cooling tower fills, scaling, deformation, aging, sediment deposition and algae propagation will occur. These will cause the plugging of the fills and the reduction of the heat transfer effect. What's worse, they can decrease of cooling tower performance and increase of energy consumption. Therefore, we need to clean and maintain the cooling tower fills regularly to extend the fills service life and increase the heat transfer efficiency.

Cooling Tower Fills Cleaning

The sediment in the cooling tower fills mainly contain lichen and algae, which are easy to grow in damp and dark environment. Besides, unfiltered earth water will bring yellow sand soils into the cooling tower fills and cause clogging. So we need to clean the cooling tower fill regularly. There are two cleaning method, you can choose one for the thorough cleaning.

Directly Clean

This method is suitable for the cooling tower fills which is used for a short time and the sediment clogging is not so serious.

1. Rinse the cooling tower fill with water gun repeatedly to eliminate the sludge and incrustation on the surface.
2. Dissolve the safe efficient detergent with around 50 °C hot water and flush repeatedly with flushing pump packing, after rinse clean until the scale (if packing service life is longer, cause aging and collapse, recommend replacing packing), at the same time to join the algae fungicidal, thoroughly destroy biological algae and bacteria.
3. Clean the cooling tower fill with fresh water to eliminate the remaining detergent and agents.

Soak Cleaning

When the cooling tower fills are used for a long time and the sediment clogging is serious, you need to adopt soak cleaning method.

1. Build a temporary pool beside of the cooling tower.
2. Put the cleaning agent in the clean water pool.
3. Disassemble the cooling tower fills and soak the cooling tower fills in the pool.
4. Clean the cooling tower fills with clean water.
5. Install the cooling tower fills into the towers.

When the cleaning and maintenance cannot work any more, you should to replace the cooling tower fills in time to ensure the smooth and stable working of cooling tower fills and cooling tower.

Cooling Tower Fills Maintenance

Properly and regularly maintain cooling tower fills can help increase the heat transfer efficiency, extend fills service life and save electricity and energy. Otherwise, the replacement cost of labour and time will sharply increase. Check out these cooling tower fill maintenance recommendations

1. Inspect tower fills regularly. Look for sediment, scale and slime every half month or every month.
2. Clean cooling tower fill surface. Use vacuums to remove contaminants
3. Treat circulate water using biodegradable descaler and dose biocides at recommended levels.
4. Drain and clean tower fills. Perform a thorough cleaning annually.

These measures can not only help control biological growth, including Legionella, they can also help improve equipment efficiency and overall operation.
