Anonymous users2024-02-15So much can be summed up from personal experience. If this is not the case, consult a water treatment equipment provider or a membrane element provider. Each product is different, but much the same.
Cause Solution: Concentration polarization, increase the return flow of concentrated water, accelerate the flow rate in the membrane tube, find out the broken wire, and repair it with epoxy resin; Or replace the ultrafiltration membrane.
Secondary Pollution Improved effluent post-treatment.
Deterioration of raw water quality Improve pretreatment to meet the requirements of ultrafiltration inlet water, the filtration accuracy is wrongly selected, and the technicians of Haideneng Company are welcome to consult and communicate at any time.

There are generally the following problems: 1. The equipment is damaged.
2. The filter membrane in the equipment has been used for too long and needs to be replaced.
I've repaired this kind of stuff before, but I don't know if you're using RO membranes, and you have to replace them in a month when the water quality is poor.
A little better. It will take 9-11 months to change it!

Anonymous users2024-02-12Are you buying water treatment equipment in **? You can ask him about the basic configuration, we are Shanghai Shuangjin fluid equipment, if you don't understand anything you can consult! The customer service attitude is absolutely 100%!
In addition, when you buy equipment, you must tell the other party what water quality you are in, and then the treatment of the rationality of water quality is the best!

Anonymous users2024-02-11The water quality is not good during the flood season, and the sediment carried by the torrential rain in the upstream is mixed. November to the following year of each year.
The water is still very clear in March and April. If you play, of course, it's spring, and the mountains and rivers are beautiful, and the fish are fat. In this season, the discharge of the two dams is more spectacular.

Hypoxic hours. Stay in the aerobic pool for a maximum of 8 hours. It should be judged according to the water quality.
aao"Process introduction and process:
The AO process is the abbreviation of anaerobic-anoxic-aerobic combination process, which is composed of a three-stage biological treatment device.
It is different from the single-stage AO process in that an anaerobic reactor is set up in the front section, which aims to degrade and remove part of the refractory organic matter in the wastewater through the anaerobic process, thereby improving the biodegradability of the wastewater, and providing a carbon source suitable for the denitrification process for the subsequent anoxic section, and finally achieving the purpose of efficient removal of COD, BOD, N and P.
Process: 1. The wastewater enters the anaerobic reactor after pretreatment, so that the high COD substances are partially decomposed in this section.
2. Then enter the anoxic section for denitrification process, and then the aerobic section for oxidative degradation of organic matter and nitrification reaction.
3. In order to ensure the efficiency of denitrification, part of the effluent from the aerobic section enters the anoxic stage through reflux, and is mixed with the effluent from the anaerobic section in order to make full use of the carbon source in the wastewater.
4. The other part of the effluent enters the secondary sedimentation tank, and the activated sludge is separated as the effluent, and the sludge is directly returned to the anaerobic section.

CO2 has been turned on to help stabilize water quality, and it is not recommended to use solenoid valves, not to mention the cost of electricity, which has no positive effect.

Anonymous users2024-02-07Let's talk about it one by one Regulating pool: The residence time of the regulating tank is mainly related to the treatment capacity of the sewage treatment system, and the main function of the regulating tank is to regulate the quality and quantity of incoming water, because some sewage changes greatly in the amount of water and water quality at different times of the day, and then it is necessary to regulate the water quantity and water quality of the regulating pool.

Cough is not easy to get better after a cold, and considering that the patient may be allergic, it is easy to induce allergic cough or cough variant asthma, resulting in prolongation and non-healing.

The results are different, mainly because the Internet is an open network, and there are many factors that affect the quality of the network, including the line, the user's computer, the use environment and the user's use and maintenance, as well as what kind of operating system and which applications the user installs. >>>More

A row of weeping willows by the river is like a graceful fairy, swaying and colorful. In spring, they pull out goose-yellow shoots and enjoy the touch of the spring breeze; In summer, they swayed their green and clear leaves in the wind, and their long branches hung down to the ground, like green streamers; In autumn, these green streamers magically turn yellow again; Winter is coming, and the snowflakes are scattered all over the sky, falling on the fine branches of the weeping willows, which seem to be covered with silver hair, and more like wearing a princess dress, which attracts the admiration of some people passing by.
