Reverse osmosis equipment operation steps
The correct operation and maintenance of reverse osmosis equipment can not only make the equipment play its maximum role, but also effectively prolong the service life of the equipment. Process flow: raw water & rarr; ÀWater inlet electric valve & rarr; ÀRaw Water Tank & rarr; À Raw Water frequency conversion constant pressure water supply system & rarr; ÀQuartz sand filter & rarr; ÀActivated carbon filter & rarr; ÀReducing bactericide addition & rarr; ÀAddition of Scale Inhibitor & rarr; ÀSecurity Filter & rarr; ÀHigh pressure pump & rarr; ÀReverse osmosis membrane module & rarr; ÀPure water tank & rarr; ÀPure water frequency conversion water supply system & rarr; À Water 1. Operation and operation of reverse osmosis device Start A. Set the air switch in the Electric Control Box to the ON position. B. Open the inlet valve of the reverse osmosis main engine and the primary RO drain valve. Check whether the whole inlet pipe is unobstructed. On the running electric cabinet, the handle is automatically switched to the manual state, and the working switch is turned to the running state. At this time, the raw water tank may overflow. C. Press'Start of raw water pump ( The two original water pumps are changed every day under normal conditions. The running original water pump should be opened before the pump and the valve after the pump is opened, and the valve that is not running should be closed)'Button, the raw water pump starts after 5 seconds. D. After 3 minutes, start the first-stage high-pressure pump ( At this time, ensure that the pretreatment tank and precision filter gas have been drained). E. Adjust the inlet valve and the outlet valve of concentrated water, close the first-level RO drain valve, and adjust the pressure in front of the membrane to the specified value (Set 1MPA) , And the flow rate is maintained at the rated flow rate of 70m 3/h. F, secondary water production, to ensure that the first-level pure water tank is at high water level, to ensure smooth pipelines, start the secondary high-pressure pump. G. After starting, pay attention to the pre-membrane pressure, post-Membrane Pressure, pressure difference before and after the membrane, water production flow and concentrated water flow of the reverse osmosis device. H, turn on level 1 before shutting down (Level II) RO drain valve, flush for at least 3 minutes, pressure and flow are reduced, can be closed level (Level II)High pressure pump, raw water pump. Note: for the element with protective liquid, it must be guaranteed that the low-pressure flushing is not less than 6 hours before it is enabled, otherwise it will affect the water yield. Stop the Machine ▲ adjust the pressure regulating valve to reduce the pre-Membrane Pressure to 0. 5MP (Some high-pressure pumps cannot do this) , Make the system run at low pressure for about 10 minutes. ▲ Close the high-pressure pump continue to run 10 minutes
Custom decorated Aluminum Cans in 2022 for Beverages
Do you want to open a food chain or a beverage company? Do you want to grow your business of soft drinks or beverages in the market? The answers to your all inquiries are here in this informative article about the importance of custom aluminum cans.
The Advantages of Using Custom Aluminum Cans
Because Custom Aluminum Cans are better for the environment, they are the best choice for food. There are more recycled materials in Custom Aluminum Cans than in other types of packaging. This makes it easier to recycle custom aluminum cans than other types of packaging.
Why Choose an Aluminum Can As a Beverage Container?
There are many reasons to use an aluminum can as a beverage container. They can be recycled multiple times, but they are also highly recyclable, generating significant economic and environmental benefits. It's also worth noting that the material is 68 percent recyclable, compared to just three percent for plastic bottles.
Custom Aluminum Cans For Beverage Brands
For the best quality and lowest price, opt for printed cans. Minimum order of 90,000 to 180,000 cans is needed, and you can expect to receive at least 12 to 25 pallets. With many different types of designs and finishes, you can create the perfect custom aluminum cans to fit your needs and budget. If you're a small business or have a limited budget, consider wrap-on adhesive labels. These cans are designed to be durable even when wet.
How is the can made?
There are two kinds of materials for making cans: one is aluminum, and the other is tinplate. The consumption of aluminum metal materials used in packaging containers in the United States reached 1,992,000 tons in 1998, an increase of 2.24% over 1997, making it the second largest consumer market, accounting for 21.6% of the annual aluminum consumption. In the United States, aluminum sheets have always been used as materials for cans, and about 40% of aluminum sheets are used in the production of cans every year. The strong opponent of aluminum in the packaging industry comes from PET materials. PET materials can be made into strange appearances through injection molds, while aluminum materials are relatively difficult. However, there is a big difference in the prices of the two materials. PET is affected by the price of oil. Aluminum can be recycled through its own recycling, reducing material costs, and is valued by environmental organizations.
Who invented the can?
In 1959, ERNIE.C.FRAZE of DRT Company in Teton, Ohio, USA, invented a can, that is, the material of the can lid is processed to form a rivet, and the jacket is pulled up. The ring is riveted again and matched with the corresponding notches to form a complete lid. The invention of this day made a historic breakthrough in the metal container after 50 years of long development. At the same time, it also laid a solid foundation for the development of the canning and beverage industry. Cans originated in the United States and became popular in the United States.
