FUNCTIONS OF COMPLEX FILTERS
The main purpose of treating such water is to soften, de-ironize and remove manganese. In order to solve this problem simultaneously, complex water filters are used. The filling of such a filter consists of a multi-component mixture of sorbent-ion-exchange materials, which are arranged in layers. This allows to simultaneously perform the following tasks:
- removal of iron and manganese;
- removal of ammonium;
- removal of heavy metal ions;
- purification from organic compounds.
ADVANTAGES OF COMPLEX WATER FILTERS
The main advantage of using complex filters is their versatility. In most cases, there is no need to install separately softeners, de-ironers or other filters, one complex purifier is enough. It can replace 2-3 conventional filters, which makes it much more convenient, as well as economical.
Complex filter effectively removes iron and regardless of its form: dissolved, organic, colloidal. pH value, hydrogen sulfide content, organics, presence of chlorine, concentration of chlorides, sulfates, hydrogen carbonates - all these factors do not affect the quality of iron removal. An important role in the complex purification of water is played solely by the total iron content.
The filter is compact, the size is no more than standard for conventional softeners.
The cost of purified water when using integrated treatment is significantly lower than when using other popular technologies.
The reliability of the filters of complex cleaning is ensured by regular regeneration, during which the load is washed of accumulated impurities and they are discharged into the drain. Regeneration takes place in three stages:
- backwashing with water;
- flushing with a solution of table salt;
- final quick flushing.
The load can serve up to 10 years if properly operated. Efficiency and small dimensions of complex filters cause their wide prevalence in commercial water treatment, as well as for domestic purposes.
