Commercial RO Water Purifier 2 Stage of Reverse Osmosis Filter;

The reverse osmosis device is to pass the raw water through a fine filter, a granular activated carbon filter, a compressed activated carbon filter, etc ro system water purifier., and then pressurize it through a pump, and use a reverse osmosis membrane (RO membrane) with a pore size of 1/10000 μm (equivalent to 1/6000 of the size of E. coli and 1/300 of the virus) to make the higher concentration of water become low concentration water, and at the same time isolate all the impurities mixed into the water such as industrial pollutants, heavy metals, bacteria, viruses, etc., so as to meet the physical and chemical indicators and health standards specified for drinking. Produces pure and pure water.
The commercial ro water purifier uses membrane separation technology to effectively remove charged ions, inorganic substances, colloidal particles, bacteria and organic substances in water. It is the main equipment in the preparation of high-purity water, brackish water desalination and wastewater treatment process commercial ro unit .

The pollutants in water that can be removed by ro water system industrial reverse osmosis equipment are

1. Water filter for machine Reverse osmosis membrane can effectively remove suspended solids in water.This type of commercial ro unit pollutant is commonly found in surface water and sewage sources, and its particle size is generally above 1 micron. In the RO pretreatment system Adding flocculant process can effectively solve this problem commercial ro water purifier.

2. Reverse osmosis membrane can effectively remove organic pollutants. Because there are many organic pollutants in raw water and the composition is complex, it is necessary to attach great importance to the organic matter in raw water.

3. Colloidal pollutants of industrial reverse osmosis equipment reverse osmosis equipment. Due to the complex composition of certain industrial wastewater, the water source of surface water and wastewater contains inorganic and monomer compounds, and it may also be a complex composed of multiple compounds.

4. Microbial pollution of industrial reverse osmosis system. Wastewater is mainly found in surface water or wastewater, usually bacteria, biofilm, algae and fungi. reverse osmosis system for sale

The technical principle of osmosis

"Infiltration" is a physical phenomenon, reverse osmosis is to exert greater pressure than natural osmosis in the water containing salt and various fine impurities (i.e., raw water), so that the water penetrates from the high concentration to the low concentration, and most of the bacterial impurities, organic matter, heavy metals, bacteria and other harmful substances in the raw water are discharged through the sewage outlet. Reverse osmosis (RO) commercial reverse osmosis water filtration system is a type of membrane separation technology, which relies on the characteristics of reverse osmosis membranes to separate solvents and solutes in solution under pressure.

Reverse osmosis system composition

The reverse osmosis system is mainly composed of a pretreatment unit, a reverse osmosis unit and an electrical control unit.
Pretreatment generally includes raw water pumps, dosing devices, quartz sand filters, activated carbon filters, precision filters, etc. Its main function is to reduce the pollution index of raw water and other impurities such as residual chlorine, and meet the inlet requirements of reverse osmosis. The equipment configuration of the pretreatment system should be based on the specific conditions of the raw water.
The reverse osmosis unit mainly includes a multi-stage high-pressure pump, a reverse osmosis membrane element, a membrane shell (pressure vessel), a bracket and so on. Its main function is to remove impurities in the water and make the effluent meet the requirements of use.
The electrical control unit is used to control the normal operation of the entire reverse osmosis system water purification machines. Including instrument panels, control panels, various electrical protection, electrical control cabinets, etc.

Flow Chart

1. Raw water tank (optional)
Raw water is stored for the sedimentation of large sediment particles and other precipitable substances in the water. At the same time, it cushions the impact of unstable water pressure in the raw water pipe on the water treatment system. (e.g., the reaction of pressure sensing caused by water pressure that is too low or too high) ro filter system.

2. Raw water pump
Constant system water supply pressure to stabilize water supply water purifier machine.

3. Multi-media filter
The main purpose of the filter is to remove the sediment, rust, colloidal substances, suspended solids and other particles contained in the raw water in more than 20um, and can be controlled by manual valve or fully automatic controller for a series of operations such as backwashing and positive washing. Ensure the quality of the produced water of the equipment and prolong the service life of the equipment ro filter for home.

4. Activated carbon filter
The system uses a shell activated carbon filter, which can not only adsorb electrolyte ions, but also carry out ion exchange adsorption. Activated carbon adsorption can also make potassium permanganate oxygen consumption (COD) from 15mg/L (O2) to 2~7mg/L (O2), in addition, due to the adsorption effect to increase the concentration of surface adsorption and copying, it also plays a catalytic role, remove pigments, odors, a large number of biochemical organic compounds in water, reduce the residual chlorine value of water and pesticide pollutants and remove trihalides (THM) and other pollutants in water. It can be controlled by manual valve or fully automatic controller for a series of operations such as backwashing and positive washing. Ensure the quality of the produced water of the equipment and prolong the service life of the equipment. At the same time, the equipment has a self-maintenance system, and the operating cost is very low.

5. Ion softening system/dosing system
In order to dissolve the concentrated discharge of solids and the utilization of fresh water, in order to prevent the concentration of CaCO3, MgCO3, MgSO4, CaSO4, BaSO4, SrSO4, SiSO4 at the concentration end of the RO device, especially on the concentrated side of the last membrane module of the RO device, from crystallizing and precipitating and damaging the due characteristics of the membrane element, before entering the reverse osmosis membrane module, an ion softening device or an appropriate amount of antiscalant should be put into the assembly to prevent carbonate, SiO2, Crystal precipitation of sulfates.

6. Precision filter
Precision filters are used to remove residual suspended solids, non-contoured particles and colloids in the inlet water, so that the operation of subsequent equipment such as RO system is safer and more reliable. The filter element is a 5um meltblown filter element, which is to remove the impurities greater than 5um that are missed by the upper filter unit. Prevent it from entering the reverse osmosis unit and damaging the surface of the membrane, thereby damaging the desalination performance of the membrane.

7. Reverse osmosis system
The reverse osmosis device uses enough pressure to separate the solvent (generally water) in the solution through the reverse osmosis membrane (or semi-permeable membrane), because this process is in the opposite direction of natural osmosis, so it is called reverse osmosis. The reverse osmosis method can adapt to all kinds of raw water with salt content, especially in water treatment projects with high salt content, and can obtain good technical and economic benefits. The reverse osmosis method has high desalination rate, high recovery rate, stable operation, small footprint, easy operation, reverse osmosis device in desalination at the same time, but also remove most of the bacteria, colloids and large molecular weight organic matter.
