雷火平台(中国)股份有限公司官网技术已经大规模的应用在各行各业,但不同的行业对水质的要求是不一样的,有很多时候给水经过雷火平台(中国)股份有限公司官网设备的膜的一次过滤后,就可以送到用水点或者其他水处理设备中,但也有一些时候,给水经过雷火平台(中国)股份有限公司官网膜的一次过滤后还达不到用水点或者其他水处理设备对水质 的要求,此时就必须对雷火平台(中国)股份有限公司官网的产水用水雷火平台(中国)股份有限公司官网膜再进行处理。

Reverse osmosis technology has been widely used in all walks of life, but different industries have different requirements for water quality. Many times, after a filtration of the membrane of the reverse osmosis equipment, the feed water can be sent to the water point or other water treatment equipment. But sometimes, after a filtration of the reverse osmosis membrane, the feed water can not reach the water point or other water treatment equipment. In order to meet the requirement of water quality, the reverse osmosis membrane must be treated for the water produced by reverse osmosis.

给水经过雷火平台(中国)股份有限公司官网膜的一次过滤称为一级处理,这样的雷火平台(中国)股份有限公司官网系统称为一级雷火平台(中国)股份有限公司官网系统,如果对一级雷火平台(中国)股份有限公司官网系统的产水用雷火平台(中国)股份有限公司官网膜再处理一次,那么后面的雷火平台(中国)股份有限公司官网系统就被称为二级雷火平台(中国)股份有限公司官网系统,目前在工业上已经有三级雷火平台(中国)股份有限公司官网系统在运行,此时,给水经过了雷火平台(中国)股份有限公司官网膜的三次过滤。

The primary filtration of feed water through reverse osmosis membrane is called primary treatment. Such reverse osmosis system is called primary reverse osmosis system. If the production water of primary reverse osmosis system is treated with reverse osmosis membrane once more, then the latter reverse osmosis system is called secondary reverse osmosis system. At present, there are three reverse osmosis systems in operation in industry. At this time, feed water passes through reverse osmosis membrane. Three filtrations.

第二级或者第三级雷火平台(中国)股份有限公司官网设备的给是回已经是前一级雷火平台(中国)股份有限公司官网的产水,因而水质很好,基本不存在污染的问题,设计时回收率可以做到更高。每一级雷火平台(中国)股份有限公司官网系统一般都需要分成几段,对于大型雷火平台(中国)股份有限公司官网系统比较常见的是一级二级雷火平台(中国)股份有限公司官网系统,简单称之为二段雷火平台(中国)股份有限公司官网。

The feed-back of the second or third-stage reverse osmosis equipment is already the water produced by the former-stage reverse osmosis, so the water quality is good, there is basically no pollution problem, and the recovery rate can be higher in design. Each stage of reverse osmosis system generally needs to be divided into several segments. For large-scale reverse osmosis system, the most common is the first stage and second stage reverse osmosis system, which is simply called the second stage reverse osmosis system.

那么雷火平台(中国)股份有限公司官网设备又是如何分段的呢?

So how to segment the reverse osmosis equipment?

对于各种雷火平台(中国)股份有限公司官网设备,往往需要不止一个雷火平台(中国)股份有限公司官网膜元件,这时候这些膜元件就存在如何排列的问题,如前面介绍,膜元件实际回收率是膜元件实际使用时的回收率。为了降低膜元件的污染速度保证膜元件的使用寿命,膜元件生产厂家对单支膜元件的实际回收率做了明确规定,要求每支1m长的膜元件实际回收率不要超过18%,但当膜元件用于第二级雷火平台(中国)股份有限公司官网系统水处理时,则实际回收率不受此限制,允许超过18%。

For various reverse osmosis equipment, more than one reverse osmosis membrane element is often needed. At this time, there is a problem of how to arrange these membrane elements. As mentioned earlier, the actual recovery rate of membrane elements is the actual recovery rate of membrane elements in use. In order to reduce the contamination rate of membrane components and ensure the service life of membrane components, the manufacturers of membrane components clearly stipulate the actual recovery rate of single membrane components, requiring that the actual recovery rate of each 1 m long membrane component should not exceed 18%. However, when the membrane components are used in the water treatment of the second-stage reverse osmosis system, the actual recovery rate is not limited, allowing more than 18%.

系统回收率是指雷火平台(中国)股份有限公司官网装置在实际使用时的总回收率。系统回收率受给水水质膜元件的数量及排列方式等多种因素的影响,小型雷火平台(中国)股份有限公司官网设备由于膜元件的数量少给水流程短,因而系统回收率普遍偏低,而工业用大型雷火平台(中国)股份有限公司官网装置由于膜元件的数量多给水流程长,所以实际回收率一般均在75%以上,有时甚至可以达到90%。

System recovery rate refers to the total recovery rate of reverse osmosis device in actual use. The system recovery rate is affected by many factors such as the number and arrangement of membrane elements in feed water quality. Small reverse osmosis equipments generally have low system recovery rate because of the small number of membrane elements and short feed water flow. However, large reverse osmosis equipments in industry usually have more than 75% actual recovery rate, sometimes even up to 90% because of the large number of membrane elements and long feed water flow.

为了提高雷火平台(中国)股份有限公司官网设备回收率,应该把膜元件串联起来,但如果系统中有很多的膜元件,就不能把他们全部串联,如果这样做,那么靠前支膜的给水流量就会很大,系统压力也太大,产水流量分配也不平衡。所以实际使用时,把一定数量的膜元件装在一个压力容器中,然后把压力容器按照一定的排列方式来排列,按照给水/浓水侧的流程,给水/浓水流人靠前压力容器为靠前段,靠前段的给水/浓水再流人下一个压力容器为第二段,依次类推为其他段的名称。

In order to improve the recovery rate of reverse osmosis equipment, the membrane elements should be connected in series, but if there are many membrane elements in the system, they can not be all connected in series. If this is done, the feed water flow of the first membrane will be very large, the pressure of the system will be too large, and the distribution of water production flow is not balanced. Therefore, in actual use, a certain number of membrane elements are installed in a pressure vessel, and then the pressure vessels are arranged in a certain arrangement. According to the flow of water supply/dense water side, the first pressure vessel for water supply/dense water flow is the first stage, and the second stage for water supply/dense water flow to the next pressure vessel is the second stage.
