The skimmer system is a technology dedicated to collecting water from the pool surface and filtering it from impurities and dirt, such as fallen leaves and insects. This system works through small openings on the pool edges that draw surface water through a pump and then direct it to the filtration unit. After filtering the water, it is returned to the pool clean and pure. Key Components Skimmer Mouth Located on the pool wall at the water surface level, it draws surface water and the impurities it carries. Skimmer Basket Acts as a primary filter to trap leaves, insects, and large debris. Weir Door Moves with the water's movement to direct it towards the basket and prevent dirt from returning. Suction Line A pipe that transports water from the skimmer to the pump. Pump Draws water from the skimmer and pushes it towards the filter. Filter Purifies water from fine impurities before returning it to the pool. Return Inlets Return clean water to the pool after filtration. Advantages Lower construction cost compared to the overflow system. Easy maintenance and access to the basket for cleaning. Good efficiency in removing floating debris. Design flexibility, as multiple skimmers can be installed in the pool depending on its size. Lower water consumption compared to overflow, as it does not require a large balance tank. Lower energy consumption compared to overflow. Disadvantages Uneven purification distribution, as it relies on drawing water from specific points only. Less effective in large or heavily used pools compared to overflow. Performance is affected if the water level is below the skimmer opening. Dirt can accumulate in areas far from the skimmer if there is no good water current. Additional Information: The number of skimmers required is usually calculated based on the pool's surface area, with each skimmer covering an approximate area of 25–35 m2 to ensure purification efficiency. The skimmer system can be used in large pools, but there are important points to consider to ensure its effectiveness: Factors Affecting Skimmer Efficiency in Large Pools Number of Skimmers In large pools, a single skimmer is not enough; multiple units are distributed along the pool edges to ensure dirt is drawn from all areas. Common Rule: Each skimmer covers approximately 25–35 m2 of water surface. Water Current Distribution Return inlets should be designed to push water towards the skimmers, preventing dirt from accumulating in distant areas. Pump Strength In large pools, you need stronger pumps or more than one pump to ensure sufficient flow through all skimmers. Environmental Conditions If the pool is in an open area and exposed to a lot of leaves or dust, you may need to maintain and clean the skimmer baskets more frequently. Advantages in Large Pools Lower cost than the overflow system in terms of construction and maintenance. Expansion flexibility by adding extra skimmers as needed. It may not achieve the same level of uniform purification as the overflow system, especially in pools with good efficiency in removing floating impurities. Irregular shapes. Performance is affected if the water level is not precisely adjusted. The skimmer can be used efficiently in large pools if the system is thoughtfully designed, with adequate skimmer distribution, adjusted water flow directions, and appropriate pump selection. To maintain the efficiency of the pool and its system, it is recommended to follow these tips: Clean the basket regularly Systems contain
