INTRODUCTION

The filter tank is usually made of sturdy and corrosion-resistant carbon steel or stainless steel, providing stable support and protection for internal components. The activated carbon filter media, as the core part, is a carbon-containing material that has undergone s pecial activation treatment. It has an extremely developed pore structure with pores of various sizes widely distributed and a huge surface area, endowing it with a powerful adsorption capacity. The activated carbon is filled in the tank according to different usage requirements to form an effective adsorption and filtration layer.

The water distribution device ensures that the water to be filtered is evenly distributed on the activated carbon filter media, guaranteeing that every part of the filter media can play its full role. The water collection device is responsible for collecting the filtered clean water and discharging it through the outlet pipeline. This equipment comes in a variety of specifications and can be flexibly selected according to factors such as the water treatment volume and water quality requirements. It can range from meeting the water purification needs of households and small office spaces on a small scale to being suitable for large-scale water treatment projects in industrial production and municipal water supply. It is easy to install, simple to operate, and runs stably and reliably, continuously and efficiently purifying water quality.

WORKING PRINCIPLE

The working principle of activated carbon filters is based on the powerful physical adsorption effect of activated carbon. When the raw water containing impurities enters the filter tank from the inlet, it first passes through the water distribution device. The water distribution device evenly disperses the water, allowing it to evenly contact the surface of the activated carbon filter media.

Subsequently, during the process of the water passing through the activated carbon filter media layer, due to the rich and unique pore structure of the activated carbon, various impurities in the water will be adsorbed into the pores. For example, residual chlorine, odor-causing substances, some dissolved organic substances, pigments, and some heavy metal ions in the water will all be captured by the pores of the activated carbon. Because these pores have different sizes and can adsorb impurities of different sizes and properties, they can conduct in-depth purification of the water. Finally, the water collected by the water collection device and flowing out from the outlet has significant improvements in aspects such as water purity, odor, and color, achieving the goals of removing odors, colors, and harmful chemical substances in the water, making the water safer, cleaner, and more suitable for use.
