Pressure washing at Georgia Aquarium is a great example of this kind of situation. As the water levels of the aquarium rise, so does the water pressure. Since so many different things are cleaned in water, the extra pressure can cause problems.
Most saltwater tanks and marine life in the Atlanta area are fed by ocean water. Seawater is hard and dense. Water used for cleaning is treated with chemicals that are not available in saltwater. Because there is so much saltwater used in its preparation, the tanks must be cleaned as thoroughly as possible.
Other things that are washed in the water are biological cells. If those cells are treated incorrectly, it can do harm to them. This could result in disease or death if not done correctly. For large, well-maintained tanks, algae growth is reduced. The reduction of this growth is beneficial to all the tanks in the Atlanta area. Even so, this is not always the case when water levels change.
While the water level in a tank is low, it can allow the heat to rise, leading to an increase in temperature. Since a tank cannot hold all the water itself, there is an overabundance of water to prevent the temperature from rising too high. During these high temperatures, many things must be cleaned.
Some of the things that are cleaned in water and cleaned again are oysters, corals, sea fans, and sea anemones. Sometimes the pressure washing must also go into the saltwater, because a tank cannot be filled with the saltwater itself. These things are generally processed in a pressure washing unit.
However, while the plants and animals may need to be rewashed in ocean water, many types of plants and animals are no longer alive and need to be moved to another facility. This is why Savannah water pressure washing plants have a dedicated facility for this type of work. Because they cannot handle the volume of water themselves, the saltwater has to come from somewhere else.
While freshwater water will not be required, the pressure washing plants in Savannah will still do some work to remove the saltwater. Depending on what type of treatment the plants are using, they may have a limited amount of freshwater to mix with the treatment. The plants do this work on a daily basis, so they have plenty of treatment at their disposal.
These plants are basically monitoring the freshwater plants, which are placed in the saltwater tanks for the end of the season. If there is any indication that there may be an abundance of fresh water after the season ends, these plants move the fresh water to the regular aquarium tanks. There is enough freshwater to keep the tanks full, though not quite to capacity.
Many of the freshwater plants that live on the bottoms of the tanks will die and float to the top of the tank, so that the fresh water is not contaminated. If there is enough, they will be moved to a fresh water treatment facility in another part of the city. This creates a problem when the saltwater tank is being worked on, because if there is no additional treatment on the way in, there is no more saltwater available for the pressure washing plants to clean.
When there is a shortage of saltwater in a tank, the pressure washing plants will have to resort to another method of removing the algae growth. Freshwater treatment facilities will typically have this solution available, since it is not used in freshwater. There is not enough saltwater to go around for both the aquariums and the saltwater treatment plants, which make the pressure washing plants a valuable part of the Savannah aquatic ecosystem.
They provide work for people who would otherwise not have the jobs because they are such a crucial part of the marine life of the Savannah area. The plants and animals that need their help to survive, in Savannah and throughout the world, benefit from the work that these workers do. so many months of the year.
