China's top ten sewage treatment equipment manufacturers ranking Which is the best sewage treatment equipment manufacturers

With the progress of industrial technology, water quality is slowly declining, water treatment equipment demand is slowly rising, then buy water treatment equipment should pay attention to what? How can I buy the right equipment for myself?

Purchase principle

Water treatment equipment prices vary, the standard is not the same, to choose the right water treatment products, only the right is the best. When choosing water treatment equipment, first consider the company's qualifications, to understand the authenticity, the company has done successful cases, how the after-sales service and other details. Will be customized according to user requirements, can also be configured with different configurations of high, medium and low end. Don't just pursue low-priced products.

After-sales service. Water treatment equipment for a long time after the use of a lot of consumables need to be replaced, or cleaning, in the purchase of the time to ask the business will not give preferential or after-sales service.

Configuration requirements

Water treatment equipment configuration, because the more specialized, so it is more traps.

For the pump, experts believe that there is no need to choose imported pumps; filter media, be sure not only than the price, than the actual parameters of the filter media; controllers, water treatment equipment can be used in a more mature and stable controllers; on the selection of the membrane, although there are many domestic membrane manufacturers, but the expert's advice is still to choose from international brands, the quality of the relatively more stable.

Enterprises do evaluation between different suppliers, must not only look at the price, because the water treatment equipment itself is a combination of parts, so it must be itemized in detail than the configuration.

Also look at the configuration is based on the actual situation of your business design, whether it can meet the water quality and use of both requirements.

Product safety

Many companies in the selection of suppliers, the primary consideration is security. Safety can be examined from the following aspects:

First of all, the safety of the process and technology, can ensure that the required indicators. For example, the effective removal of heavy metal ions, microbial content control. The component parts of the water treatment equipment is safe, there shall be no harmful dissolved substances.

Secondly, the material of the pipeline material. Because the water treatment equipment from the water inlet to outlet will flow through a variety of pipes and filter materials, so we must control the material of these pipes and materials, to avoid adding new harmful secondary pollutants to the water.

Lastly, the alarm system. When the equipment malfunction, there must be an alarm system to avoid contaminated water into the processing section.

The actual situation of the enterprise

Finally, according to the actual situation of their own enterprises to choose a cost-effective supplier.

Summary of the above, we should be aware of the following four in the selection of water treatment equipment:

Look at the qualification

Chinese people *** and the State Ministry of Health Health Supervision Center of the Ministry of Health explicitly issued: drinking water sanitation supervision and management methods.

The twenty-first article clearly points out that: all the Ministry of Health involved in the issuance of health permit approvals for the product are "driving without a license", is not protected by law.

Look at the material

Modern renovation of the waterway renovation know that to buy pipe, pipe fittings to buy a good, after installation, but also a pressure to try the water. So the second thing to look at when choosing a water treatment device is the tank material. Currently on the market there are stainless steel, fiberglass, cast iron, aluminum, food-grade resin or PVC and other materials. The first three belong to the pressure resistance of the material is better, can be used as a pre-filter. The latter two belong to the pressure resistance of the material is relatively poor, can only be used in the rear of the pre-filter, used as a drinking machine.

These materials, pressure resistance and corrosion resistance to stainless steel is the best. The price is also relatively high.

Determine the function

Choose the water treatment equipment to first clarify their own purpose, first from the big concept of whether to purify water or to soften water.

Purifying water is to remove sediment, impurities, bacteria, heavy metals, residual chlorine, organic matter, and some minerals in the water.

Water softening is to remove calcium and magnesium ions in the water, the most direct that is scale.

General water softening only need to use cationic resin can complete the ion exchange, remove calcium and magnesium ions. Softened water has the advantage of cleaning the skin, washing clothes soft and smooth, protecting the water heater and faucet, the shower is not blocked by scale, and the sink is no longer water stained.

Purifying water, unlike softening water, requires the combined use of many different filter media to achieve the intended purification requirements. Each filter media can play a different role in purification, how to reasonably match the composition of the filter media by the key.
