Thermal energy storage (TES) systems are cooling systems that can use ice banks, brine systems, or chilled water storage tanks for the purpose of eliminating a heat load. In reality, the chillers for the TES run outside of the times when the electricity is at its highest demand. This procedure saves the owner money and energy, while easing the load on the electrical system.
Space is needed for energy storage. Economic difficulties arise when treating systems that use chilled water storage tanks due to their sheer size. But, several challenges may arise with water treatment in thermal storage systems or TES Systems. Let’s review the challenges with water treatment in the thermal storage systems.
What are the challenges with water treatment in thermal systems?
The main is?sue is that of low velocity flow in thermal storage systems!
Tank sizes can vary widely, with typical tank quantities exceeding a million gallons. The total volume of a system can be in the millions of gallons. Systems with TES have low flow velocity regions as a result of their design. In low flow locations, particularly in the storage tanks, biofilm can grow and particles can assemble. Low flow velocity can contribute to fouling, corrosion, and the development of biofilms, all of which shorten system life and reduce heat transfer efficiency.
With any closed loop, corrosion, fouling, and microbial control are issues. Application of the proper biocides and corrosion inhibitors, together with mechanical treatments like filtration using RO Plants, are used to solve these issues. Program success is increased by routinely checking for inhibitor levels, corrosion by-products, and microbiological development, using field test techniques.
Use of corrosion inhibitors in thermal storage systems
The use of concentrated corrosion inhibitors is advantageous, due to the economics of treating such a huge volume of water. In comparison to other methods, soluble silicates and concentrated azoles can offer very cost-effective corrosion control. Alternative treatments include phosphates, molybdate, and nitrite, although phosphates and nitrite are nutrients for microbiological growth.
It can be challenging to eliminate or control well-established microbial communities, especially in such vast systems that experience changing flow. Using conventional non-oxidizing biocides to suppress microbial growth in systems, with millions of gallons of water is expensive. Additionally, the leftovers from standard biocide breakdown can eventually be converted, into nutrients for microbial development. Because of these factors, chlorine dioxide can be a treatment method of choice.
Use of chlorine dioxide for water treatment in thermal storage systems
Low dosages of chlorine dioxide have very good effectiveness. Bacterial growth is unaffected by the breakdown products. Chlorine dioxide diffuses to low flow parts of the system, and also reaches the biofilm because it is a dissolved gas.
It is less reactive than conventional oxidising biocides, and while it is less corrosive at target dosages, it is more selective for the target pollutants.
Use of RO Plants in thermal storage systems
Reverse osmosis is a technique for purifying or desalinating polluted water by pushing water over a membrane. Reverse osmosis water can be used for a variety of things, such as desalination, wastewater treatment, pollutant concentration, and the recovery of dissolved minerals.
In thermal storage systems, it can be used as a mechanical water purification system along with disinfection techniques, like UV, ozone or chlorine.
