Adsorbent Water

In light of the requirements among the known methods of sewage treatment to specified standards (ion exchange, membrane, sorption), the most promising sorption, provided that applicable in the technological process of cleaning the adsorbent is capable of a long time (months or even years) to serve water purifiers, ie, clean filtered through the water out of the entire complex being in it of harmful impurities in the recovery of sorption activity of the adsorbent through regeneration carried out directly in the filtration plant. Sorption method of natural and waste water using activated carbons and zeolites, has long been known. However, the wide distribution he has not found due to the fact that these adsorbents are filtering single-use materials. Regeneration of activated carbon and zeolite costly and time consuming operation and under the existing water treatment facilities is not feasible because it requires discharging material from the filter, activating it outside the water treatment plant on a special setup, delivery otregenerirovannogo material back to the treatment plant and loading it into the filtering structure. If you follow the path of single-use adsorbents, apart from the enormous cost of replacing the material there is the possibility of environmental hazard, since for reliable disposal of waste contaminated adsorbent in huge quantities requires large economic costs. Operational and economic disadvantages of the sorption method of cleaning water and sewage by traditional adsorbents eliminated by the use of process water treatment of the adsorbent with a high surface activity of grains, which allows to restore the sorption capacity by technologically simple, short time of regeneration, carried out directly in the filter building.
