ZGD750 Macroporous strong basic anion resin

Description

1. Description:Hydrolite ZGD750 is a macroporous, strong, basic styrene-based anion exchange resin. It effectively removes high-molecular-weight organic compounds, negatively charged organic dyes, and electrically neutral compounds. It is particularly suitable for decolorizing starch sugars due to its fast exchange rate and excellent adsorption properties. Furthermore, it exhibits high decolorization and strong antiseptic properties. Its suitable pore size and pore volume produce ZGD750 with a relatively large specific surface area, resulting in high adsorption capacity and antiseptic properties.

4. Operating instructions

Operation	Solution	Flow rate (BV/hour)	Dosage (BV)
Sugar recovery	Clean water	2.0~4.0	2.0~3.0
Backwash	Clean water	2.0~4.0	1,5~2,0
Regeneration	8~10% NaCl + 0,5~2% NaOH mixed solution	1,5~2,0	2,5~3,5
Kneading	Clean water	1.0~2.0	1,5~2,0
Rinsing	Clean water	10~15	4.0~6.0
Washing	Original solution	2.0~4.0	30~60

Note: When starting backwash, the flow rate should be slow, after all the resins become flexible, increase the backwash speed gradually, when the resins are fully activated, stabilize the backwash speed until the water after backwash is clear.
