Du Sheng Tulsion? CH-90 ISO-9001 / ISO-14001 / OHSAS-18000 instance recovery of nickel removal guide Tulsion? CH-90 is a with iminodiacetic acid functional group and a very durable type of giant hole shape-selective chelating co-type ion exchange resins. Applications:? Tulsion CH-90 is particularly suitable for the removal of cationic heavy metals. Giant porous resin structure ensures superiority of ion diffusion, giving an efficient and complete removal of the regeneration performance. This resin can remove metals from the water with a low PH, and is the most cost-effective way. PH adjusted to an appropriate range to remove metal, but must keep the following 6 to prevent the metal oxide and hydroxide precipitates generated. This resin has a higher affinity for nickel, selectivity sequence as shown below: Ni> Zn> Co> Mg> Ca> Na removal of nickel recovered recommended operating conditions: The following operating conditions for general usage guidelines. Regeneration conditions and the flow rate should be selected depending on the application. Temperature 5 - 70 ℃ resin bed height of 800mm or more (for higher feed TDS of at least 1200mm above, in order to achieve better water quality requirements) Operating flow rate of 10 - 20BV / H regeneration regeneration HCl or H2SO4 concentration 4--5% Operating Performance Here is the information given in accordance with the general method of use. Of course, before any engineering design, the best can be the raw material liquid to be processed were cylindrical test that performance under the conditions of use of the preparation. This is the entrance PH performance and concentration. Water nickel concentration: 1. Ni = 5.0ppm - 2000 ppm according to Ni With TDS = 3000 - 4000 ppm working capacity, leakage, for PH and amount of regenerated catalyst feed concentration HCl / H2SO4 120 - 200 gpl according to 100% HCL, 160 - 300 gpl according to 100% H2SO4 regeneration time of 30 - 60 minutes wash rinse 2 BV slow pace of work within 2 BV 60 converts minutes step with the number of NaOH regenerant NaOH 120 - 160 gpl NaOH according to 100% NaOH regenerant Level 2 - 3% of the contacts time is approximately 45-60 minutes slow wash 2 BV rinse water quality within four minutes to work rate of 2 BV recycled water for acid dilute acid, caustic soda and diluted with demineralised water softener regeneration regeneration process is completed in two steps, first with a nickel or swapped out, then the resin is converted to sodium. A preliminary study found that only acid can also work, but further research found that the conversion step of the resin with superior performance. Regeneration program does not rely on switching capacity or other parameters, but complete conversion of active groups. When the nickel content ranges raw material liquid when 500ppm to 2000ppm, the best work flow 5-10BV / h. Performance Tulsion? CH-90 extremely selective ion exchange process has been extremely efficient, unlike other processes such as reverse osmosis, it only needs to be removed for the solution of specific ions. For other unrelated ions, such as sodium, calcium, bicarbonate and chlorine, is not affected. Tulsion? CH-90 has removed the typical characteristics of the water or wastewater to be treated in the heavy metal ions.
