What are the reasons for the decline in water production capacity of water treatment equipment?

Released Date: Apr 27,2016 Article Source: Yuanlai Water Treatment

The main reasons for the decline in the water production capacity of water treatment equipment are as follows: 1. The reduction in the number of membrane modules. 2. The membrane modules should be compacted in accordance with the designed number of membrane modules. When operating under conditions far exceeding the reference pressure, the membrane module will become compacted. Replace the membrane module. 3. Operate under conditions of higher recovery rate. When operating under a recovery rate of over 75%, the volume of concentrated water decreases, which leads to an increase in the water concentration ratio within the membrane module. As a result, the quality of the feed water deteriorates significantly. Due to the increase in osmotic pressure of this feed water, the permeation volume decreases. In severe cases, salt scale will precipitate on the membrane surface. 4. During operation, the pressure difference of the reverse osmosis device rises according to the designed recovery rate of water production. Improve the operation and management of the pretreatment device, improve the reverse osmosis water quality, and use

　　"Led toWater treatmentThe main reasons for the decline in the water output of the equipment are as follows:

　　1,Membrane moduleA decrease in quantity. It should be operated in accordance with the designed number of membrane modules

　　2The compaction of the membrane module occurs. When operating under conditions far exceeding the reference pressure, the membrane module will become compacted, and the membrane module should be replaced

　　3Operate under conditions of a relatively high recovery rate. in75%When operating under the above recovery rate conditions, the volume of concentrated water decreases, and as a result, the concentration ratio of water within the membrane module increases, leading toWater supplyThe water quality has seriously declined. Due to the increase in osmotic pressure of this feed water, the permeation volume decreases. In severe cases, salt scale will precipitate on the membrane surface. Produce water according to the designed recovery rate

　　4During operation, the pressure difference of the reverse osmosis device rises. Improve the operation and management of the pretreatment device, improve the reverse osmosis water quality, and clean the membrane modules

　　5Metal oxides and contaminants adhere to the film surface. Perform low-pressure flushing every day

　　6Low-pressure operation. Operate at the designed reference pressure

　　7The decrease in operating temperature. According to the designed temperature25Operating at Celsius

　　8The mixture of oil. Note that oil must not enter the feed water to replace the membrane module

　　To solveReverse osmosis water treatment equipmentThe water production volume has declined..First, the cause must be identified.Then formulate countermeasures for handling. Based on our company's many years of experience in operating various water treatment equipment.The main reasons for the decline in water production can be summarized as follows.

　　Serial number, cause, countermeasures

　　1The reduction in the number of membrane modules shall be operated in accordance with the designed number of membrane modules

　　2Low-pressure operation is carried out in accordance with the designed reference pressure

　　3Membrane module compaction occurs when the operation is carried out under conditions far exceeding the reference pressure. The membrane module should be replaced

　　4The reduction in operating temperature shall be in accordance with the designed temperature25Operating at Celsius

　　5Operating under conditions of a relatively high recovery rate75%When operating under the above recovery rate conditions, the volume of concentrated water decreases, and as a result, the concentration ratio of water within the membrane module increases, leading to a significant decline in the quality of the feed water. Due to the increase in osmotic pressure of this feed water, the permeation volume decreases. In severe cases, salt scale will precipitate on the membrane surface. Produce water according to the designed recovery rate

　　6Metal oxides and contaminants adhering to the membrane surface should be flushed under low pressure every day

　　7During operation, the pressure difference of the reverse osmosis device rises. Improve the operation management of the pretreatment device to enhance the reverse osmosis water quality Clean the membrane module

　　8When oil is mixed in, be sure that the oil does not enter the feed water. Replace the membrane module

: EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

: Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

: Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
