When does a quartz sand filter need to be cleaned and backwashed?

Quartz sand filters are generally used as pretreatment for reverse osmosis and ultrafiltration equipment, mainly for the retention and adsorption of silt, colloids, metal ions and organic matter. Common filter materials include quartz sand, activated carbon, anthracite, manganese sand, etc. It is widely applied in various industries such as agricultural irrigation, chemical engineering, petroleum, metallurgy, and mining. Now let's talk about when quartz sand filters need to be cleaned and backwashed? Firstly, the cleaning and backwashing of quartz sand filters are for different operational purposes. Cleaning is an action carried out when the efficiency of backwashing declines. Backwashing is to remove the pollutants captured in the filter, ensuring that the filter's filtration function can continue to operate. The following is an introduction to the differences between the two. The operation timing of backwashing for quartz sand filters is mainly determined by the decrease in the flow rate of the circulating pipeline per unit time

How to maintain a household water purifier?

With the improvement of living standards, more and more families choose to secretly switch to household water purifiers. Among them, the filter core is the core component of the equipment, which directly affects the water quality of the output. To use it reasonably, let's talk about how to maintain household water purifiers below? After using a water purifier for a long time, it is necessary to frequently flush it. This can effectively extend the service life of the water purifier. 2. If the tap water supply is cut off, remember to first open the drain valve to completely remove the sediment, rust and other impurities in the tap water pipe, and then open the purified water to use the purified water. 3. With long-term use of the water purifier, its water output will gradually decrease, but the water quality produced remains qualified and can be used with confidence. 4. Sometimes we may have to go on long trips. If the water purifier is not used for more than three days, when it is used again, it should be flushed forward repeatedly for 2 to 5 minutes until all the water in the purifier is drained

What causes the water hardness of the softened water equipment to be high?

The sampling port test of the softened water equipment was qualified, but the water hardness in the softened water tank exceeded the standard mainly due to the following reasons: A. The resin softening regeneration cycle was set too high, or the softened water flowmeter malfunctions, causing inaccurate measurement, which prevented the cation exchange resin from being regenerated in time when it should have been regenerated, resulting in hard water exceeding the standard being injected into the softened water tank. B. The forward wash time is too short, causing part of the waste brine that should have been washed away during the forward wash to be carried into the softened water tank. The sampling port of the fully automatic water softening equipment has been tested multiple times, but all have failed. The main reasons are as follows: A. The O-ring at the junction of the pipe and the fully automatic softening control valve has not formed A seal. At this time, the following should be checked: ▲ Whether the length of the pipe is sufficient and whether the outer diameter meets the requirements ▲ Whether the O-ring seal was forgotten to be installed

FLECK control Valve (Boiler Softening Water Equipment)

I. Hazards of Boiler Scaling Boilers are indispensable power and heating equipment in modern industrial society. After long-term operation, boilers develop problems such as scaling and rusting, which lead to poor heat transfer performance, reduced boiler efficiency, increased fuel consumption, and higher operating costs. At the same time, there are issues such as bulging of boiler tubes, explosion risks, and shortened boiler lifespan. Therefore, after the boiler is scaled, necessary methods should be taken to remove the scale and rust and prevent their recurrence. After long-term operation, boilers inevitably develop problems such as scale and rust. The main reason for the formation of scale in boilers is that the feed water contains hardness components. After continuous evaporation and concentration under high temperature and high pressure, a series of physical and chemical reactions occur in the furnace, forming hard and dense scale on the heating surface. Scale is the "scale" of boilers. All kinds of harms

Common problems that occur during the operation of FLECK control valves

The FLECK control valve of FLECK is the core component of the water softener, consisting of a multi-way valve and a regeneration control device. Now let's talk about the common problems that occur during the operation of the FLeck control valve. 1. The soft water output is substandard. The system's feed water pressure does not meet the requirements. The FLECK water softener requires a feed water pressure between 2 and 6Kg/cm ². When the feed water pressure is less than 1.75 Kg/cm ², the flow rate of the water ejector used for salt suction is too low to generate sufficient negative pressure to draw in salt water. It is manifested as insufficient salt absorption (there is still remaining saturated brine in the salt tank after the regeneration process is completed), a decline in the regeneration quality of the water softener, and the output of the equipment in the next water production cycle is definitely insufficient. The solution to this problem is to increase the water supply pressure to meet the requirements. Generally, a booster pump can be used to achieve this. When the water supply pressure is greater than 6 K

: 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.
