The simple answer is recycling it with reverse osmosis filtration. If you own a swimming pool you are going to run into problems with Total Dissolved Solids (TDS) especially if you live in the Southwest United States. According to Wikipedia Total Dissolved Solids are referred to as, “a measure of the combined content of all inorganic and organic substances contained in a liquid in molecular, ionized or micro-granular (colloidal sol) suspended form.” Simply put this can be easier summarized by the calcium and other hardness minerals in the fill water along with salts etc. This is one way that a variety of swimming pool industry people recommend that you should drain your swimming pool. Although this is one way you can test for hardness minerals in the swimming pool, if done correctly, testing for calcium hardness should be the most widely used test for accuracy of needing to change out the water in your swimming pool.
When water evaporates, hardness minerals stay behind in solution and overtime these hardness minerals start plating on the tile line, the liner, and equipment. Over time, calcium destroys your swimming pool. If not properly dealt with it can cause damage to the plumbing and equipment and can be an eyesore along the decorative tile and water features. You can pay to have the calcium removed from the tile line but if you don’t deal with the water and lower the calcium and total dissolved solid levels in the swimming pool, it will come back quickly. We recently recycled a 25,000-gallon swimming pool that yielded the following before and after results…..
Initial Chemistry
Total Dissolved Solids – 4256ppm
Calcium Hardness – 800ppm
Cyanuric Acid – 200 plus ppm
After recycling this swimming pool for 20 hours and conserving 85% of the water we left the swimming pool with the following chemistry….
Ending Chemistry
Total Dissolved Solids – 820ppm
Calcium Hardness – 180ppm
Cyanuric Acid – 60ppm
Most conventional wisdom would recommend a drain and refill of the swimming pool but it’s a huge water waster and doesn’t really solve the problem. Depending on where you live in the United States, the fill water is extremely hard and when refilling a swimming pool it doesn’t give you the best solution….. plus it is a huge water waster. That’s why our mobile filtration “Puripool” Process is the best solution not only because it allows you to conserve 85% of the existing water in the swimming pool but it also gives you drinking quality water in your swimming pool. It was designed to lower calcium, total dissolved solids, cyanuric acid, phosphates, salts and so much more. Choosing to go this route will not only allow you to conserve water but will deliver you a must better product than fill water.
