Brief Intrduction
Starch production has special requirements on water quality, because the calcium and magnesium ions in the water will bond with hydrogen of starch molecules glucose unit and decrease the affinity between glucose unit and water, which will lead to a decliningin starch viscosity.
According to industry statistics, Brabender starch viscosity index when using reverse osmosis water treatment equipment is 500-800BU higher than not using it. Therefore, reverse osmosis water treatment equipment shall be used to remove water ion during production so as to guarantee starch quality.
With the development of living standards and the application of starch in the food industry, the health indicators of nationalpolicy is much more strict. The traditional technology of producing starch is unable to meet the national health indicators demand, and only by using reverseosmosis pure water production can guarantee the quality of starch, because it can effectively remove dissolved salt in water, colloid, microorganisms, organic matter, inorganic matter and so on (removal rate is as high as 99%), ensuring processing water health indicators to meet the national standard. Reverse osmosis pure water equipment is an good option for high pure water preparation, desalination of brackish water and wastewater treatment process and it is widely used in electricity, medicine, food, textile, chemical industry and other fields.
Structure Principle
RO is today's most advanced, energy-saving, efficient separation technology. The principle of the equipment is an reversed movement of osmosis,and it is a separation method by means of selection and interception of semipermeable membrane to separate the solute and solvent under pressure. In the water treatment process, using this technology can remove inorganic ions in water, impurities such as bacteria, viruses, and colloidal organic matters.
Reverse osmosis pure water treatment equipment will firstly preprocess the water through quartz sand filter, activated carbon filter, the 5 microns security filter, in order to guarantee the original water to meet reverse osmosis water standards. Then increase pressure by the high-pressure pump and use 1/10000 microns (1/6000 of the size of e. coli, 1/300 of the virus) reverse osmosis membrane membrane element ( or semipermeable membrane) to isolate dissolved salts in water, colloid, microorganisms, organic matters, inorganic impurities total is, so that the physical and chemical standards and sanitation standards stipulated in drinking water regulation can be met.
