Is there any fertilizer factory that recovers potassium salts from wastewater?
Thread Content
The company used some potassium hydroxide solution to neutralize and accelerate the reaction, and the potassium salts were eventually discharged in the wastewater. Considering that potassium salts are one of the three main fertilizers used in agriculture, it would be a waste to use them in wastewater treatment; approximately 11,000 tons per year of 48% potassium hydroxide is diluted to a concentration of 10–20%. Is there any fertilizer company willing to take this material for recycling? The location is around Chengdu.
Some fertilizer companies may recycle potassium salts from wastewater. You can consult local fertilizer manufacturers to see if any are interested in this and have the capability to handle it. Additionally, you can also contact the local wastewater treatment plant to see if they can take the potassium salts in the wastewater and process them for recycling. .
There must be quite a few impurities in the wastewater; otherwise, one could simply evaporate, concentrate, and crystallize it to sell the resulting product
It definitely has recycling value. You can contact salt waste recycling companies; it may be necessary to treat the waste through evaporation or incineration before it can be reused
It has value for recycling; it can be turned into liquid fertilizer for sale. The market is available for this, so go ahead and process it into liquid fertilizer by yourself
I can test your wastewater and assess its feasibility as a fertilizer product, focusing on indicators such as toxic and harmful organic substances and heavy metals
The processing costs are too high. Currently, potassium chloride costs around 500 dollars per unit. It’s not possible to export it, unless it can be classified as hazardous waste and sent to Laos
