What is the market outlook for UASB at the moment?
Thread Content
Recently, I plan to enter the field of industrial pharmaceutical wastewater treatment. However, it seems that working in the environmental protection sector is not easy these days; for companies, implementing environmental protection projects is a costly endeavor, and no one is willing to spend money on it. Another thing: is it also a problem with cash flow when dealing with large-scale equipment like UASB these days? Could the experienced seniors in this community share their views and analyses on this market? We can also discuss it together. Thank you all! !
From a technical perspective, UASB is relatively versatile and well-developed. Some companies have also started to abandon EGSB and IC in favor of UASB. UASB has a high price and also requires a high level of technical expertise.
Is there a significant gap between the domestic level of UASB and foreign levels in terms of design and price?
Personally, I think there is still a gap between the anaerobic level in China and that abroad. Of course, it’s not ruled out that some domestic experts are quite good at anaerobic processes. Domestic companies, following the standards, produced anaerobic tanks. Companies with technology sell that technology ； Companies without technology sell steel.
The answer above is correct; however, for the pharmaceutical and fine chemical industries, USAB isn’t a panacea
Thank you for your reply. What is the COD removal rate of UASB systems in China? It’s claimed to be around 90%, but I don’t think it can be that high The claimed COD removal efficiency for UASB systems abroad is also 90%; do you think the actual performance abroad can match that claim?
For domestic UASB systems, the removal rate for wastewater that is easy to degrade is around 80%; I have seen few cases where the removal rate exceeds 85%. It’s just propaganda; there’s a lot of exaggeration in it. It can also be considered a selling point created by the company for marketing purposes. There isn’t much experience with anaerobic contact abroad, so I can’t speak rashly.
We are developing a system for treating high-concentration formaldehyde wastewater, using the process of iron-carbon + Fenton + UASB + SBR. The UASB is designed to handle an influent COD of 8000, with a removal rate of 70%; the anaerobic treatment capacity is 60 m3/h
The designed influent formaldehyde concentration is 2000 ppm
It is indeed quite high. . . How are the experiments going now? How effective is the formaldehyde treatment in each section? ? What I’m more concerned about is the formic acid concentration in the inlet and outlet water of the UASB. . .
