With the progress of Industrial Science and technology, water quality is slowly declining and the demand for water treatment equipment is slowly rising. What should we pay attention to when purchasing water treatment equipment? How can we buy the appropriate water treatment equipment? What is the development of water treatment industry valve industry? Let's look at it together.

First of all, I would like to talk about the purchase principle. Water treatment equipment has different prices and standards. To choose suitable water treatment products for water treatment equipment manufacturers, only suitable ones are the best. When choosing water treatment equipment, first consider the company's qualifications, to understand the authenticity, the company's successful cases, after-sales service and other details. Do not blindly pursue low-priced products. Hangzhou water treatment equipment will be customized according to user requirements, but also can be configured in different configurations of high, middle and low-end. After-sale service. After long-term use of water treatment equipment, a lot of consumables need to be replaced or cleaned. When purchasing water treatment equipment, you should ask whether the merchants will give preferential treatment or after-sales service.

First of all, understand our configuration requirements, water treatment equipment configuration, because more professional, so it is trapped. For some low-power pumps, such as those below 10KW, experts do not think it necessary to choose imported pumps, such as domestic manufacturers'products can completely reverse osmosis pure water equipment to meet the requirements. In terms of filter material, we must not only compare the price, but also the actual parameters of the filter material. For example, the price difference between iodine adsorption value 750 and 900 for the same activated carbon filter material is nearly double. As for the controller, the equipment can adopt more mature and stable controllers. Regarding the choice of membrane, although there are many domestic membrane manufacturers, experts'suggestions are still in the choice of international brands, and the quality is relatively stable. When enterprises evaluate different suppliers, they must not only look at the price, because the water treatment equipment itself is a combination of components, so it is necessary to compare and configure in detail one by one. In addition, it depends on whether the configuration is designed according to the actual situation of your enterprise, and whether it can meet the requirements of water quality and use. Second, we should pay attention to the safety of products, such as: for pharmaceutical enterprises, drug safety is the top priority. Therefore, when choosing suppliers, pharmaceutical companies should first consider safety. Safety can be inspected from the following aspects: First, the safety of process and technology can ensure that the required indicators are met. For example, the effective removal of heavy metal ions and the control of microbial content. Secondly, the components of water treatment equipment are safe and harmful leachate is not allowed. Because water treatment equipment will flow through various pipelines and filter materials from the inlet to the outlet, it is necessary to control the material quality of these pipelines and materials so as to avoid adding harmful secondary pollutants to the water. The last is the alarm system. When the equipment fails, there must be an alarm system to avoid polluted water entering the pharmaceutical processing section. Finally, according to the actual situation of their own enterprises, choose a supplier with high performance-price ratio.

So to sum up the above, we should pay attention to the following four points when choosing water treatment equipment:

Article 1: Qualifications.

The Health Supervision Center of the Ministry of Health of the People's Republic of China clearly promulgated the Measures for Sanitation Supervision and Management of Drinking Water

Article 21 clearly states that:

Therefore, all products without the approval of health license issued by the Ministry of Health belong to "driving without license" and are not protected by law.

Specific inquiry methods should be consulted by the public in the health administrative license

Article 2: Look at the material.

Modern people renovate waterway renovation know to buy pipes, pipe fittings to buy good, after installation, but also a pressure test water. Why? I'm afraid of running. Fire and water are merciless, which is a vital matter.

So the second thing to look at when choosing a water treatment device is the material of the tank. At present, there are stainless steel, fiberglass reinforced plastics, cast iron, aluminum, food-grade resin or PVC and other materials on the market.

The first three materials are of good compression resistance and can be used as pre-filter (central machine).

The latter two materials belong to the poor compression resistance, which can only be used in the back end of the front filter (central machine) for direct drinking machine.

Among these materials, stainless steel is the best in compressive and corrosion resistance. Prices are also relatively high. Food extreme resin or PVC has poor compressive resistance and low price.
