1. What is the water consumption of the ion exchange pure water machine?
The ion exchanger does not discharge waste water during the whole process of water production, but only needs water consumption during regeneration. Generally, the water consumption can be counted as 5-10% of the water production.
2. What is the acid-base consumption of the ion exchange pure water machine, and how long can it be used for each regeneration?
The acid-base consumption of the ion exchanger is related to the performance of the ion exchange resin. However, the common anion exchange resin used in the cation anion exchanger on the market requires 30% hydrochloric acid per liter of resin, and 99% caustic soda per liter of anion resin. 100g
How long it takes to regenerate the ion exchange resin after each regeneration, mainly related to the water quality required for the water end point (ie, the water quality standard) and the raw water quality (ie TDS) and the exchange capacity of the resin (ie, the water exchanged per liter of resin) The ability of salt), so different production environments and different quality ion exchange resins and different waters have different regeneration cycles. It has been shown that the double bed ion exchanger has a conductivity of 200 μS/cm or less in raw water, a water production of 15 μS/cm or less, and 75 liters of cation resin + 75 liters of anion resin.
3. What is the effluent quality of the ion exchanger in general?
The water quality of the ion exchanger system is mainly based on the raw water quality. The water quality of the double ion exchanger is 1-15μS/cm, while the water quality of the single-stage mixed bed is 1-0.1μS/cm. The water quality is below 0.1μS/cm
4. Why is the water quality of the mixed bed effluent better, what are the requirements for the influent?
Mixed bed is the abbreviation of mixed ion exchange bed, which means that the two kinds of ion exchange resins of cation and yin are placed in the same exchange library, and they are stratified during regeneration, respectively, and acid and alkali are regenerated. Mix them evenly during operation, and rinse them into operation.
Since the cation and anion resin are mixed uniformly in the mixed bed, the cation and anion exchange reactions are carried out almost simultaneously, or equivalent to many stages of yang, yin bed series and single stage bed (yang bed, yin bed). Compared with the salt removal process, the mixed bed demineralization process has good effluent quality, stable operation and obvious exchange end point.
Generally, the water quality requirements of the mixed bed water inlet are better after the first-stage desalination treatment, and the general conductivity is below 10 μS/cm.
5. What is the difference between an automatic ion exchanger and a manual ion exchanger?
The automatic ion exchanger mainly controls the valve switching by electric or pneumatic or hydraulic pushing valve action. The automatic ion exchanger can control the water quality of the produced water after setting the regeneration and running procedures for the first time. Produce water, fail to pass the flushing or regeneration, low labor intensity and easy operation.
6. What are the commonly used automatic ion exchangers?
Commonly used automatic ion exchangers are mainly divided into two categories: automatic multi-way valve control, representative of the series of automatic multi-way valves of the US OSMONICS company 172, 180, 182, 255, 263, etc. and 9600 of the American FLICK company. , 5600 and other models and Italian series of automatic multi-way valves, mainly through the time axis or flow control valve opening and closing to achieve program control purposes, its performance is stable, but the general program is relatively fixed.
The other is an automatic ion exchanger controlled by PLC+ pneumatic or electric valve. This system control is mostly used for medium-sized water treatment and desalination projects. The control steps and processes can be set according to the needs. Can better adapt to the needs of specific procedures.
Winter is the season when a large number of cabbage are on the market, and there are many dishes made with them, such as hand-shredded cabbage, fried pork with cabbage, fried cabbage with cabbage, cold cabbage, fried cabbage with vermicelli, etc., all of which are very delicious. Among the dishes, shredded cabbage is the best!
