VONTRON   ULP31-4040 Membrane Element.

Brief Introduction：

ULP series of ultra low pressure aromatic polyamide RO element is developed by VONTRON for treatment of surface water and underground water. Its operation pressure  is  about  2/3 of low pressure membrane, and the rejection rate can reach 99.5%. Thus it can reduce the investment cost of related pumps, pipelines, containers and other equipments and the operation cost  of reverse osmosis system, improve economic benefits.

ULP series RO element normally suitable for treatment of surface water, underground water and municipal water with TDS is less than 2000 ppm. It is mainly applied in bottle water, drinking water, boiler replenishment water, food processing and pharmaceutical manufacturing industries and other fields.

Size of Membrane Element：1.0 inch=25 .4 mm

Notice:

1.All  data  and  information provided  in  this  manual  have  been  obtained  from  long-term experiment  by  VONTRON.  We  confirm the  effective  and  accuracy  of the  data.  VONTRON assumes  no liability  for any  aftermath  caused  by  user’s  failure  in abiding by  the  conditions specified in this manual in use or maintenance of membrane products. It is strongly recommended that the user shall strictly abide the designed use and maintenance requirements and keep relevant records.

2.The permeate value  listed in the table is the average value. The permeate  flow of single membrane element is tolerance not exceeding ±20% of the nominal value.

3.All wet-type membrane elements have been  strictly tested before leaving the factory, and have been treated with 1.0% sodium hydrogen sulfite (10% glycerin antifreeze required in winter) for storage purpose, then sealed with plastic bag in vacuum, and further packed in carton boxes.

4.The membrane used  should  remain wet after initial wetting; In long term suspension, to prevent the breeding of microbes, soak the membrane elements with protective solution is highly recommended, the solution (prepared with RO filtered water) containing 1.0% sodium hydrogen sulfite (foodstuff-purpose).

5.Operate low pressure flushing for 15-25 minutes of first use, high pressure flushing for 60-90 minutes when first use (Permeate volume no less than 50% of designed volume).    Discard all the permeate and condensed water produced during the first one hour after system start-up.

6.During  storage  time  and  operation period,  it  is  strictly prohibited  to  add  any  chemical medicament  that  may be harmful to membrane  elements.  In  case  of any  violation  in adding chemical medicament, VONTRON assumes no liability for any damages incurred.

7.Along with technical development and product renovation, all information will be subject to modification without prior notification. Please keep notice the website  of VONTRON  for any updates of the product.
