Ⅶ. Ultrafiltration system treatment equipment

Introduction of ultrafiltration system equipment:

1.Ultrafiltration principle:

Ultrafiltration is a membrane separation process based on the separation principle of sieve and driven by pressure. The filtration precision is within 0.005-0.01 microns, which can effectively remove particles, colloid, bacteria, heat source and polymer organic materials in water. It can be widely used in separation, concentration and purification of substances.

2.Classification of ultrafiltration equipment:

Ultrafiltration membrane can be divided into plate and frame type (plate type), hollow fiber type, nano-membrane surface ultrafiltration membrane, tube type, coil type and other structures. Hollow fiber ultrafilter (membrane) has the advantages of high filling density and small occupation area.

3.Ultrafiltration process:

In the process of ultrafiltration, aqueous solution flows through the membrane surface under pressure, and the solvent (water) smaller than the membrane hole and small molecule solute permeable membrane become purification solution (filtration solution), and the solute and solute group larger than the membrane hole are trapped and discharged with the flow, becoming concentrated solution. The ultrafiltration process is dynamic filtration, and the separation is completed in the flow state. Solute deposition is limited on the membrane surface, the ultrafiltration rate attenuates to a certain extent and tends to balance, and can be restored by cleaning.

Ⅻ. Swimming pool circulating water treatment equipment

Working principle of circulating water treatment equipment in swimming pool:

(1). The first step is aeration with oxygen

Above the swimming pool, swimming pool water treatment equipment room through the water pump to water processor aqueous humor equipment automatic aeration of the upper part of the oxygen tank for fully dissolved oxygen, automatically dissolved oxygen process is a process of imitating human lungs, at the same time of receiving enough oxygen, breathe out the harmful gas of ammonia nitrogen with "gas", at the same time through an air water mixture, can enhance the agglomeration effects of pollutants in the water, which benefits the effective sewage of the filter medium.

(2). Refined filtration

Swimming pool water treatment equipment of automatic oxygen melting pool by distribution in the tank flows into four fine filter to filter, due to the filter layer USES a different ore materials from big to small filter layer, so that the water won't because of the pressure through the filter layer form the idler, at the same time, in the process of sewage, can be in the form a thin layer of biofilm on the surface of filter medium, can further oxidation of organic matter and minerals in the water and the filter medium minimum grain diameter in millimeters, far less than the traditional quartz sand filter material, strong ability of sewage, so water quality is very good.

(3). Back wash

Backwash process completely on their own according to the change of internal pressure filter to determine whether the implementation of recoil, and the unscientific way of the non-traditional process regularly recoil specific principle is as follows: the water by the distribution of water tank into the fine filter, filter from top to bottom, as the suspended solids in the filter layer intercept water continuously, the head loss of filtration layer increases gradually, the siphon, pipe burst in the water level rise when the water level rose into the siphon water ejector, auxiliary tube because of hydraulic effect will be the rainbow tube air away, the formation of negative pressure When the negative pressure reaches the design value, siphonage occurs. At this time, the water filtered by the other three fine filters is backwashed from the bottom up to the fine filter and the filter medium is backwashed continuously. When the water level in the water tank drops to the specified value, the siphonage is destroyed and the backwash ends, and the filter device starts working again.

How is pool water sterilized:

(2). The half-life of ozone in the swimming pool is the existence of only about 10-20 minutes time, the swimming pool when handling equipment offer actual measurement is only about 3 to 5 minutes, and the water filtering operation rate of the time more than it, therefore, water containing ozone water from the wall, soon there will be no disinfection sterilization ability, a swimming pool in the middle of the ministries and is incomplete disinfection sterilization, so can swimming pools using ozone alone, must be in addition to organic residual type sanitizer, in short, the use of ozone in the swimming pool is only auxiliary function.

(3). Wimming pools using ozone should be aware that the concentration of ozone near the outlet in the pool should not be too high, otherwise there will be damage to the respiratory tract.

(4). The diffusion efficiency of ozone is determined by the size of air bubbles. The smaller the surface area of air bubbles, the greater the chance of contact with water. Therefore, too large air bubbles are not only ineffective, but may even cause respiratory tract burns due to the overflow of unreacted ozone contained in air bubbles.

(5). Because the filtration operation rate of massage pool is very short, when using ozone in massage pool, attention should be paid to the problem of ozone accumulation, the use of ozone generation machine with ultraviolet water to destroy ozone after the design is safer.
