What is the difference between hopcalite and activated carbon

Hopcalite and activated carbon are both commonly used materials in the field of water treatment. Hopcalite is a coagulant that can quickly condense in water and quickly precipitate suspended matter. Activated carbon is an adsorbent with a highly porous structure and a large specific surface area, which can effectively adsorb organic pollutants and heterochromatic substances in water.
Hopcalite can adsorb particulate matter in water through electrochemical action and form sediments, thereby purifying the water body. Activated carbon removes harmful organic substances from water by adsorbing and decomposing them.
Hopcalite is mainly used in water treatment in petrochemical, metallurgical, papermaking and other industrial fields, especially for quickly precipitating high-concentration particulate matter. Activated carbon is widely used in the treatment of ordinary drinking water, purified water, mineral water and other drinking water. Its strong adsorption capacity can effectively remove pollutants such as heterochromatic substances and organic substances in water.
The advantage of hopcalite is that it can quickly precipitate high-concentration particulate matter, which can play an important role in purifying some special industrial wastewater. The disadvantage is that the effect is not as stable as activated carbon. If the particulate matter after sedimentation cannot be completely filtered and removed, it may have a certain impact on the downstream environment. The advantage of activated carbon is that it has strong adsorption capacity and good removal effect on various heterochromatic substances and organic substances. It can be widely used in drinking water treatment and other fields. The disadvantage is that it needs to be replaced regularly and the economic cost is high.

In summary, hopcalite and activated carbon are both commonly used materials in the field of water treatment, but due to their different functions and application scenarios, they need to be selected and applied according to specific circumstances
