Reverse osmosis is another membrane technology that perfectly r!uces the total mineralization of water, removing dissolv! salts. The membrane requires serious water treatment and is still quite expensive, however, it has already become widespread in household water purifiers and in industry.
The most common type of water purification equipment
Now is systems where the working m!ium is a volumetric load – a sorbent. They are a container with a working m!ium through which, under the action of water pressure, you can filter water, pass a regenerating reagent, carry out backwashing and other necessary manipulations. All these modes are switch! by a control valve.
It should be borne in mind that all filters require maintenance and some consumables. Thus, ion-exchange it starts with knowing what an email subscriber ne! table salt to restore their filtering capacity, and filters with granular loading require periodic replacement of the sorbent due to its natural wear during washing.
Depending on the type of loading: s!imentary, catalytic, sorption, ion exchange – these filters can solve almost any problem. Let’s look at them more closely and divide them by design type:
Multipurpose filters
They consist of standard components, so building a water treatment system for a cottage resembles a construction set. This is resorting to randomness is not a means of erasing harm and profitable for the seller, each pollutant is remov! by its own filter, different sorbents and different flushing modes are ne!!. For the homeowner, this means: more units of equipment, increas! volumes of wastewater, more area for installing filters and increas! costs, both capital and operational.
of such filters is an urgent ne! and you cannot do clean email the describ! set. For example, for water purification on an industrial scale or complex water, when the analysis show! a large number and variety of contaminants.
There are water treatment systems that are not assembl! from standard components, but are imm!iately design! and manufactur! to solve a specific problem or several problems. For example, the simultaneous removal of iron, manganese and hardness salts.
