Online Low Range Turbidity Controller for Swimming Pool

Turbidity is an indicator that reflects the physical properties of swimming pools. From the perspective of disinfection and safety, the turbidity of pool water should be higher than or equal to the sanitary standards for drinking water. The conventional water treatment for swimming pools in China is sedimentation-sand filtration-chlorination. Under normal and reasonable operating conditions, the turbidity can be controlled at ≤1~2NTU. With the improvement of water quality requirements, in recent years, China's swimming pool water turbidity standard has been raised to ≤0.5NTU. The world health organization points out that the suitable turbidity of swimming pool water quality is 0.5NTU, the German swimming pool water quality standard is 0.2~0.5NTU, and the Spanish swimming pool water quality standard is 0.5~1NTU. There are usually several methods for monitoring the turbidity of swimming pool water: observation method, which determines the turbidity by observing the turbidity of swimming pool water with the naked eye. This method is highly subjective and not accurate enough. It is a simple preliminary judgement method. The filter paper method is to immerse the filter paper in the swimming pool water and observe the deposition of particles on the filter paper to determine the turbidity. This method is suitable for the measurement of larger particles. Currently the most widely used method is to use a Turbidity Meter to measure turbidity. Turbidimeters determine the turbidity of suspended matter in water by measuring the scattering of light in water. Daruifuno's online DUC2-TU Turbidity Controller can be connected to a Turbidity Sensor based on the scattered light method to measure the turbidity value of various types of water quality. If it is used in swimming pool water, the turbidity value is very low, and it needs to be matched with a laser flow low turbidity sensor OLTU600 model.

Monitoring the turbidity of swimming pool water is very necessary and is related to the health of swimmers. What are the causes of turbidity in swimming pool water?

1. The design of the circulation filtration system is insufficient, and the operating parameters of the filtration system are not reasonably designed, such as the circulation period is too long. The online turbidity controller has two relays for controlling the water turbidity and make automatic control of other device.

2. There is a problem with the pH balance of the water. If there are too many calcium ccarbonate particles in the pool water, it will cause turbidity.

3. The growth of algae. Since algae grows in a series of divisions, the growth rate is very fast. Once it appears, the transparency of the pool water will immediately decrease.

4. Heavy load, such as a large number of swimmers suddenly entering the pool, or heavy rain in the open-air swimming pool, a large amount of water containing impurities, etc. will also increase the turbidity of the swimming pool water.

So how to control swimming pool turbidity? First, use an online Turbidity Analyzer to monitor and provide timely feedback on the turbidity value of the swimming pool so that timely measures can be taken. Secondly, different methods should be adopted for different problems of increased turbidity. For example, add algaecide regularly, use wire brushes to scrub the surface and corners of the swimming pool, reasonably control the number of people entering the swimming pool, and guide swimmers to shower before swimming. If the outdoor swimming pool encounters heavy rain, add 2 times the amount of disinfectant before the rain. If it is lower than 7.5, add a regulator to raise the pH to prevent the rain from bring in algae growth.

Therefore, if you want to control the water quality and safety of your swimming pool, in addition to monitoring turbidity, you usually also need to detect pH value, ORP value, residual chlorine value, etc. Daruifuno is a manufacturer specializing in the R&D and production of water quality analysis instruments.
