[0037] Working Principle: The drinking water arsenic removal device of this application features a control module that monitors the operating status of each module in real time and performs automatic control. Raw water first enters the pretreatment module via a raw water booster pump. Large particulate impurities, suspended solids, and some organic matter are removed through the filter element. The pretreated water then enters the adsorption module through pipes, where arsenic ions are adsorbed and removed by the adsorption material. The adsorbed water then enters the security filter for filtration before reverse osmosis. After passing through the security filter, the water enters the reverse osmosis module. Under high pressure, water molecules permeate through the reverse osmosis membrane, while other impurities are retained, achieving deep water purification. The purified water then enters the purified water storage module for storage, providing users with healthy drinking water and protecting public health. Furthermore, the pretreatment tank, adsorption tank, and storage tank are made of low-temperature resistant materials and equipped with insulation layers to adapt to cold environments such as Tibet. The pretreatment module, adsorption module, security filter, and reverse osmosis module are connected by quick-disconnect pipes and valves, allowing for easy replacement of each module and facilitating maintenance and installation. Furthermore, the water tank is equipped with a liquid level sensor. When the water level in the tank reaches its lowest point, the control module can control the raw water booster pump to pump in new water to be treated for purification and arsenic removal.
