1. Product Introduction:
H103 is a type of large-pore adsorption resin, non-polar, mainly developed for adsorbing and separating small molecule organic compounds, belonging to the polystyrene system. Due to a special manufacturing process, the pore size is very uniform and it has a high specific surface area. It is widely used in organic wastewater treatment, removal of organic residues in food, removal of pesticide residues in agricultural products, and removal of organic residues in traditional Chinese medicine, among other applications.

4. Product Applications:
1. Mainly used for organic wastewater treatment, capable of removing or recovering most organic substances.
2. Juice purification, decolorization of fruit acids, and removal of bitterness.
3. Separation and purification of antibiotics, vitamins, steroids, amino acids, enzymes, etc.
4. Separation and recovery of non-polar substances such as phenol from polar solvents.
5. Adsorption and separation of flavonoid substances.
5. Main Treatment Processes:
1. Comprehensive Wastewater:
Wastewater ----Flocculation and Sedimentation ---- Plate Frame Filtration ---- Quartz Sand Filtration ---- Resin Adsorption ---- Discharge up to standard or reuse
Resin Desorption ---Production Reuse
Common desorption agents: acetone, methanol, ethanol, 2-5% sodium hydroxide
2. Single Wastewater in Production:
Resin Adsorption ----Desorption and Reuse
3. Wastewater difficult to treat to standard with a single resin:
Two to three types of resins can be selected for stepwise adsorption and desorption.
6. Resin Pretreatment
Industrial-grade resins may contain dispersants, pore-forming agents, inert solvents, and other chemical residues, so pretreatment should be performed according to the following steps before use.
1. Clean the adsorption column and pipelines before loading, and drain the water inside the equipment to prevent contamination of the resin by harmful substances.
2. Add water equivalent to the resin filling volume into the adsorption column, 0.5 then add the new large-pore resin into the column, discharge the excess water from the bottom of the column, and keep the water level about 20 centimeters above the resin layer surface until all resin is transferred into the column.
3. Slowly add water from the bottom of the resin, gradually increase the water flow rate to allow the resin bed to nearly fully expand, maintain this backwash flow rate until all bubbles are expelled and all particles are fully expanded, with small resin particles flushed out.
4. Use 2 times the resin bed volume ( 2BV ) of ethanol, pass through the resin layer at a flow rate of 2BV/h , and maintain the liquid level height, soaking overnight.
5. Use 2.5-5BV ethanol, 2BV/H The flow rate passes through the resin layer, washing until the effluent mixed with water is not white and turbid.
6. Release a small amount of ethanol from the column to check if the resin is clean; otherwise, continue washing the column with ethanol until it meets the requirements. Inspection method: a. Detection of water-insoluble substances: Take an appropriate amount of ethanol eluent, mix with an equal volume of deionized water, the solution should be clear; then at 10 ℃ place 30 minutes, the solution should still be clear. b. Check for non-volatile substances: Take an appropriate amount of ethanol eluent, at 200-400nm Scan the ultraviolet spectrum within the range, 250nm There should be no obvious ultraviolet absorption around
7. Use deionized water at a flow rate of 2BV/H to pass through the resin layer to wash off ethanol.
8. Use 2BV4% of HCL solution, at a flow rate of 5BV/h to pass through the resin layer and soak for 3 hours, then wash with deionized water at the same flow rate until the wash water is neutral ( pH test paper detection pH=7 ).
9. Use 2.5BV 5% of NaOH solution, at a flow rate of 5BV/h at a flow rate to pass through the resin layer and soak 3 hours, then wash with deionized water at the same flow rate until the wash water is neutral ( pH test paper detection pH=7 ).
10. Method for determining the endpoint when resin adsorption reaches saturation: The drug solution passes through the resin column at a certain speed. According to the estimated dosage, near this point, take about 3ml and place in a stoppered test tube, seal tightly and shake vigorously. Observe the foam duration; if the foam lasts for 10ml minutes or more, it is positive, indicating the resin has reached saturation. 15 minutes or more, it is positive, indicating the resin has reached saturation.
VII. Others
1. Product transportation and storage:
Store the product in a wet state, preferably at a temperature above 0 degrees; if not used for a long time, it can be sealed or added with 5% or more saline; during transportation, mainly prevent freezing, and do not place heavy objects on the resin to avoid crushing it.
2. Before the liquid enters the resin column, it should undergo flocculation, filtration, or sand filtration to ensure it does not contain suspended solids to avoid clogging the resin pores.
3. Resin not used for a long time in the column is best cleaned and removed for storage, or saline can be added in an anti-salt medium. If stored in the column, keep the surface from dehydration and perform periodic backwashing of the resin to loosen it and prevent clumping and spoilage.
