For those of you that have been following along, we started recycling Cal Lutheran’s 780,000 gallon main swimming pool one week ago. We knew this was going to be a large project because of the volume of the swimming and the fact that our mobile filtration trailer can only process 40,000 gallons of water in a 24-hour period but quality of water and water conservation is the most important factor with this University and this swimming pool. When we started a week ago we estimated it would take approximately 3 weeks to complete and today marks the first week of completion. Last Tuesday, we rolled in with our Reverse Osmosis (RO) filtration mobile trailer and found the swimming pool to have the following initial chemistry:

Calcium hardness – 950 ppm

Total Dissolved Solids (TDS) – 14,450 ppm

Salts – 9945 ppm

When it comes to any swimming pool, especially commercial pools, all of these numbers are extremely high! The thought of draining a pool this size was definitely not an option for Cal Lutheran because of the amount of downtime and how much water would be wasted. The biggest challenge for them was that they needed to do something with the water so they contacted us to recycle the water instead. With our mobile filtration trailer, we come to you to process the water through our trailer. The process is pretty simple because the intake hose takes water from the swimming pool into our trailer where 6 sets of RO membranes lower calcium hardness, TDS, cyanuric acid, salts, phosphates, waterborne diseases and so much more! After the water is processed through the membranes, drinking quality water returns to the swimming pool and over time (about 3 weeks due to size of pool) we will leave them with better water than tap and they will also be able to conserve roughly 85% of the existing water in the swimming pool. These factors were vital for Cal Lutheran but knowing that they would have no downtime because you can swim in the pool while it is being processed was another factor that went into their decision.

After one week of processing the water, the above levels have been lowered to the following:

Calcium hardness – 600 ppm

Total Dissolved Solids – 11,500 ppm

Salts – 7434 ppm

Now that the water hardness is lowering these numbers will continue to lower at a much more rapid pace and we are on target to complete this job in another 2 weeks. Stay tuned for more updates on this swimming pool. If you have any questions on how we can help you with mobile filtration, call us today at 1-714-694-3116
