As the weather gets hotter and summer gains momentum, it’s time to hit the pool. If you want to enjoy a cool summer, a swimming pool is essential. In addition to having a pool that meets comfort and aesthetic standards, careful selection of water treatment equipment is also crucial. The good pool water treatment equipment can reduce the owner’s operating costs and maintenance time. This article mainly introduces the selection principles and precautions of swimming pool water treatment equipment.
Pool water treatment equipment selection principles
High filtration accuracy
Filtration accuracy is the primary consideration when choosing pool filtration equipment. The filtration device of modern swimming pool cleaning equipment has abandoned the traditional sand tank filtration and replaced it with membrane filtration technology. The filtration accuracy is as high as 6-15 microns, and the minimum point is as high as 6 microns. The resulting water quality is clear and clean, fully meeting the requirements for swimming pool water. The water treatment equipment with high filtration accuracy can better deal with the situation that the water surface of the pool often appears floating, and create a clearer and cleaner pool water.
Cost saving
It is preferable to install the pool filtration equipment directly at the edge of the pool, eliminating the need for a separate machine room and reducing the floor area, thus significantly saving on civil construction costs; In addition, the investment cost of water, electricity, medicine and labor is low, with the necessary disinfection and cleaning maintenance, the water can be changed once a year (excluding the addition of new water, that is, to supplement the water evaporated by air), choose the water treatment equipment with built-in LED high-brightness energy-saving underwater lights and own escalators, so that there is no need to install additional underwater lights and traditional independent escalators, saving costs.
Simple operation and maintenance
- Priority should be given to pool water treatment equipment without embedded pipes for convenient installation;
- A preferred method is the filter bag cleaning approach, which can be washed directly with a spray faucet for ease of operation;
- Priority should be given to water treatment equipment that is simple to maintain, operates quietly, and can be automatically turned on and off;
- Priority is given to the pool filtration equipment that ordinary people can work as long as they have simple training and do not need professional technicians to take care of.
Durable material
Opt for water treatment equipment with a one-time injection molded device shell, made from corrosion-resistant materials. These should be of strong quality, have a long service life, and offer UV resistance, ensuring durability and relieving concerns about the equipment’s quality.
Filter material for filtration equipment – selection criteria for quartz sand
The main function of quartz sand in the swimming pool is filtration. There are two main types of quartz sand filter materials commonly used, one is ordinary quartz sand, and the other is refined pickling sand. Quartz sand filter material, characterized by its high hardness, good corrosion resistance, high density, and high mechanical strength, along with a long service cycle for pollution carrying capacity, is an ideal material for chemical water treatment. Quartz sand filter material plays a filtering role, just like water infiltrates the ground through sand and stone, blocking the suspended objects in the water, mainly for those small suspended objects.
Quartz sand used for swimming pool water filtration is a kind of refined quartz sand filtration material. In the sand tank, it is generally necessary to replace it once every 2 to 3 years, and usually after pollution, the quartz sand covered by pollutants can not return to a good filtration effect, and can only be replaced. The particle size of refined quartz sand filter material varies; it includes fine quartz sand with a diameter of 1-2mm, medium quartz sand of 2-4mm, and coarse quartz sand of 4-8mm. Different sizes of quartz sand have their own characteristics. Fine quartz sand can filter out fine impurities, but the filtration speed is relatively slow. Coarse quartz sand filters faster, but it may not be as effective. Select different sizes of quartz sand according to water quality requirements. The pool sand filter uses quartz sand to remove small dirt in the pool. Quartz sand is packed into a cavity inside the filter. When the control knob is placed in the “FILTER” position, the pool water containing suspended dirt particles is pressed into the filter pipe by the pump, and then guided to the filter outlet by the control switch. The pool water passes through a filter and the fine dirt is removed by a sand bed. The filtered water is returned by the pipe to the pool through a control switch at the bottom of the filter. The filtration process is complete.
