After reading the description of this device, the walnut shell refers to that hard shell, right? It is said that it needs to undergo special treatment – how exactly is that treatment carried out?
This filter is a separation device developed based on the principle of filtration and separation. It uses an oil-resistant filtering material – special walnut shells – as the filtering medium, taking advantage of the large specific surface area, strong adsorption capacity, and high dirt-trapping ability of walnut shells to remove oil and suspended particles from water. This device has both automatic and manual control modes. During filtration, the water flows from top to bottom, passing through the water distributor, the filter media layer, and the water collector to complete the filtering process. During backwashing, the agitator flips the filter media, and the water flows from bottom to top, allowing the filter media to be thoroughly cleaned and regenerated.
So walnut shells have this use too – they’re a real treasure in the chemical industry. Eating walnuts helps improve brain function, and walnut shells can also be used for filtering; there’s no waste at all. I suggest that chemical factories start providing walnuts going forward
Haha! The original poster is very creative; we support you.
A filter using walnut shells as an adsorbent.
Isn’t it just a type of activated carbon?
Walnut filters are used for wastewater treatment in chemical plants: lol
