1. Nakamoto once said that the number of bitcoins is fixed at 21 million. Since the bitcoin was g out, the price has been high. However, with more and more miners, we all see the fat of blockchain mining. Mining is naturally more and more difficult, so it is very important to choose a good miner. At present, the mainstream miner is ASIC miner, graphics card miner, GPU miner, storage miner. Specifically, we need to find a professional mining platform to ask, such as jinhoe mining, professional mining platform, each miner model should have it, you can try to ask.
2. The filter is an indispensable device in the medium pipeline, which is usually installed in the pressure recing valve, pressure relief valve, constant water level valve, square filter and other equipment. The filter is composed of cylinder, stainless steel filter screen, blowdown part, transmission device and electrical control part. After the water to be treated passes through the filter cartridge of the filter screen, its impurities are blocked. When it needs to be cleaned, as long as the detachable filter cartridge is taken out and re loaded after treatment, it is very convenient to use and maintain.
3. The precision of wastewater discharge is high. As for whether ultrafiltration is better or reverse osmosis is better, there is no standard answer. It depends on whether the local water quality is white, with more scale and hardness. See if it's necessary to install reverse osmosis.

5. Choose big brands, such as 3M in the United States. The prefilters of these big brands are quite good, and the standards are relatively high. They are more comfortable to use, but at the same time, the price will be much higher. However, choose the right place or can get a lot of concessions! For example, there is a group buying meeting in Beijing called easy clothes. The 3M purified water in the meeting will be hundreds cheaper than the activity price in the store, and it can also enjoy after-sales and service in the store, which is quite affordable. Only when the purified water is used can we know how much it will improve the quality of life.

Fish tank filter brand recommendation: Jiabao, Minjiang, Yuwang, Haipai, Sensen
1. It combines physical filtration and biological filtration in a filter tank. In this filter tank, it is divided into several layers, mainly including filter cotton and biochemical cotton. In the lower layers, biochemical ball, rattan cotton, glass ring, quartz ball, microbe house and other filter materials are placed respectively. The disadvantage is that it takes up the upper space of the aquarium and affects the appearance of the aquarium to a certain extent
purchase attention:
1. Choose the right size and shape
when you buy a fish tank, don't just look at the price of the fish tank or other aspects, you should first decide the size of the fish tank before you choose. Rooms are different in size and personal preferences, so choose according to the size and shape of the fish tank
2. When choosing a fish tank according to the material, you should pay attention to the material of the following fish tanks to see what the material is. Generally, you will choose glass. The glass fish tank is more suitable for home use, and the other is called acrylic. This kind of fish tank is more suitable for larger rooms
7. The following is a brief introction of the common filter system, hoping to help you choose the right filter
I. upper circulation filtration (upper filtration)
the upper filtration is placed on the upper part of the aquarium tank, and the water is pumped into the upper filtration tank by the submersible pump. The water flows back to the aquarium tank through the outlet pipe at the bottom after passing through the filter cotton, biochemical cotton and various filter materials
advantages: low price, simple structure, convenient cleaning and maintenance
disadvantages: occupying the upper space of the aquarium, affecting the appearance of the aquarium to a certain extent, limited internal space, less filter materials, so the biochemical filtration effect is general. In addition, because the area of the upper filtration water will increase the escape of CO2, it is not suitable for the aquarium with aquatic plants< Second, trickle filtration (drip filtration)
trickle filtration is an integrated filter. To put it bluntly, it is the upper filtration of advanced extended version. The submersible pump used is the same, and there is no special place. It combines physical filtration and biological filtration in one or more filter tanks. The filter tank is divided into several layers (the specific number of layers can be increased or decreased according to the needs). The upper layer of the filter tank is the physical filter room, which mainly contains filter cotton and biochemical cotton. The lower layers are respectively equipped with biochemical ball, rattan cotton, glass ring, quartz ball, bacteria house and other filter materials. When the water flows through, it will increase the contact surface with the air, so as to increase the oxygen capacity and provide the most ideal living environment for aerobic bacteria
advantages: perfect physical and biochemical filtration and good filtration effect
disadvantages: it also occupies the upper space of the aquarium, affects the appearance of the aquarium to a certain extent, and the sound of water flow is relatively large
style: single layer long strip trickle filter box, which is suitable for fish tank with cover; There are also multi-layer and multi box trickle filter boxes, so the filtering effect is more powerful
TB can be purchased as single-layer or multi-layer box, and the filtering effect will be better if the single-layer box is slightly modified< Back filter and side filter are separated by glass on the back or side of the fish tank. The inner part of the back filter and side filter is divided into several small grids for placing filter materials and circulating pump. One side is provided with an overflow port. When the water pump pumps water from the filtering part to the fish tank, the overflow water from the fish tank flows into the first grid of the filtering part through the overflow port, Under the guidance of the diaphragm, the water flows through various filter materials, and the water from the last grid is sent to the fish tank again through the water pump to form a circulation
advantages: make use of the internal space of the fish tank to make the fish tank and filtration form a whole, and can complete the better filtration process without using other positions outside the tank. Some equipment can be placed in the side filter / back filter, and proper placement will not affect the positive visual beauty of the fish tank
disadvantages: occupying part of the tank space, the tank space will be reced, limited by the width or length of the tank, the placement of filter materials will also be limited, and the evaporation of water will cause the water level in the interval between the pumps to decrease rapidly, which requires frequent water replenishment.

8. The first
aquarium top filter
is a filter device placed on the top of the aquarium. The water in the aquarium box is pumped into the filter box with filter layer by a small pump, and the water flows back to the aquarium box through the filter layer, so as to remove the impurities in the water and purify the water quality
advantages: it can make full use of the space on the top of the aquarium and is convenient for daily maintenance and cleaning
disadvantages: the filter device is placed on the top of the fish tank, which affects the viewing from the top to the bottom and is not suitable for the rearing of the fish
the second
air lift bio cotton filter
fixes the bio cotton at the inlet of the water pump, forces the water flow to circulate in the bio cotton by the water pump, and the air is mixed in the water flow to increase oxygen according to the jet principle. The resial food, biological excrement and other organic substances in the water can be adsorbed on the surface of the sponge
advantages: simple structure, low unit price, directly put into the fish tank water
disadvantages: the filtering principle is simple and the effect is poor. It is necessary to clean the biochemical cotton frequently and put it in the fish tank to affect the viewing. It is suitable for small fish tanks in breeding period and isolation treatment period, but it has little effect when the water quality is too dirty
if the filtering effect is good, the bottom filtering should be used; Power saving is the side filter and back filter; Easy to clean up on the number of top filtration. Also depends on your environment, the size of the fish tank, and what kind of fish to raise
hope to adopt it
