Comparison of new stainless steel sand cylinder and glass fiber

1. Stainless steel sand tanks are very corrosion-resistant and are the main filter equipment for mariculture and aquariums, while glass fiber sand tanks have poor corrosion resistance and limited scope of use, so they cannot be used for this purpose. 2. The material of the new stainless steel sand cylinder is strong and durable, and the cylinder body is not damaged forever. The effective service life is at least 15 years; the life of the glass fiber sand cylinder is 5 years. 3. The effective temperature resistance of the stainless steel sand tank can exceed 300 degrees, while the temperature resistance of the glass fiber sand tank is only 43 degrees; it is the main filter equipment in the hot spring industry.

4. The material of the stainless steel sand tank is environmentally friendly and will not cause secondary pollution to water quality. The glass fiber sand tank will slowly dissolve, causing secondary pollution to the water quality. The glass fiber dissolved in water will cause serious damage to the human body. The use of glass fiber sand tanks has been banned in developed countries. 5. The stainless steel filter sand tank has a smooth surface, excellent texture and high grade; the size, flow rate and shape of the equipment can be customized according to customer requirements.

----It is best to replace the silica sand of sand filters every 1-2 years for the following reasons:
a During backwashing, the filtration bed volume will expand upwards by 1.2 to 1.3 times. The water flow will drive the filtration layer to flow up and down, causing the filtration material particles to collide with each other. Backwash will let the small sand evacuate.
b.Some silica sands will be welded when the acid and alkali are changed due to insufficient purity;
Therefore, the longer the time, the worse the filtering effect of the sand tank. Since backwashing will consume and take away some sand, we need to replace the sand in the sand tank within the specified period.
