Reverse Osmosis Technology

First, reverse osmosis equipment

Ro Reverse osmosis is the use of sufficient pressure to make the solution of the solvent (usually refers to the water) through the reverse osmosis membrane (a semipermeable membrane) and separated from the direction of infiltration, can be used more than osmotic pressure reverse osmosis method Separate, purify and concentrate the solution. The use of reverse osmosis technology can effectively remove dissolved salts, colloids, bacteria, viruses, bacterial endotoxin and most organic matter in water. Reverse osmosis membrane is the main object of separation of ions in the solution range, no chemicals and can effectively remove water in the salt, the system desalination rate is generally more than 98%. So reverse osmosis is the most advanced and most energy-efficient, environmentally friendly way of a desalination, has also become a mainstream pre-desalination process.


The system is made of advanced composite film, showing higher solute separation rate and transmission rate. Outstanding resistance to chemical, temperature and external pressure chisel performance: membrane components of the pressure loss is small, saving energy; installation, operation more convenient, flexible, economical and reasonable. Pretreatment includes multi-media filtration, activated carbon filter, softener, can remove large particles of impurities, suspended solids, improve RO membrane water index, and effectively remove the raw water odor, residual chlorine, improve the taste of water quality. The host adopts imported high efficiency ultra low pressure composite membrane, single membrane desalination rate of 99.6%, the use of imported high and low pressure protection, the equipment failure rate is reduced to zero, the water index fully meet the national standard of pure water.

Second, the ultrafiltration system

Ultrafiltration equipment is a kind of membrane permeation separation technology which can purify, separate or concentrate the solution. In the continuous spectrum from reverse osmosis to microfiltration filtration range, ultrafiltration is between nanofiltration and microfiltration. (MWCO) is about 500-500000, and the approximate size of the corresponding pore size is about 0.005-0.1 μm (microns). Ultrafiltration membrane for the solution of particles, colloids, macromolecules and solvents and other small molecules separated.

Features:

1, the use of high strength and high toughness of the modified polypropylene hollow fiber membrane CREFLUX series of ultrafiltration element, continuous wire, flux, anti-pollution, the operation without the need for chemical dispersion washing, through the recoil can restore flux ;


2, the components of the hydraulic load uniform, no dead ends, in the backwash and chemical cleaning pollutants easier to discharge


3, to adapt to a variety of water quality, water production is clear and transparent, SDI stability ≤ 3, better than RO system water requirements


4, compact, very small footprint


5, modular design, easy to expand


6, fully automatic operation, maintenance-free work
