Benefits of technology
This patented technique allows for processing many types of waste materials that were used during production without causing harm or contamination problems. These mixtures can then be applied on crops through various methods like spraying them onto soil or applying them via irrigation systems. By doing these techniques, we aim to reduce airborne particulate matter (PM) emissions while improving nutrients absorption into plants' roots.
Problems solved by technology
This technical issue addressed in this patents relates to improving the quality of filtered cake from Potassium Stabilization Technologies Inc., which produce filters for use with crops like tomatoes or peas during their manufacturing process. These filtering processes generate large amounts of residue called filter dirt, making it difficult to dispose off properly when disposing them back after being reused. Additionally, there may also be concerns about harmful chemicals released through burning the spent material at industrial facilities where they were stored over time.

Embodiment 1
[0010] Example 1 Take 3 parts of filter mud, 2 parts of heavy superphosphate, and 1 part of calcium-magnesium phosphate fertilizer and mix them evenly. After standing for one day, it becomes a mixed fertilizer containing 15% of available phosphorus.
Embodiment 2
[0011] Embodiment 2 Get 3 parts of filter mud, 4 parts of ammonia superphosphate, and 1 part of combustion ash and mix evenly to become a mixed fertilizer containing 8% of available phosphorus and 2-3% of ammonia.
Embodiment 3
[0012] Example 3 Take 4 parts of filter mud, 5 parts of superphosphate, and 1 part of calcium magnesium phosphate fertilizer and mix them evenly to form a mixed fertilizer containing 11% of available phosphorus.

The invention relates to a technology for recycling waste filter sludge generated in a potato starch plant. The technology comprises the following steps: adding a conditioner to non-dried filter sludge, carrying out a mixing reaction to prepare a powdery or granular mixed fertilizer with excellent physical properties, and adding appropriate amounts of nitrogen, phosphorus, potassium, rare earth elements and a plant growth regulator to prepare various binary and ternary composite fertilizers containing the rare earth elements or the growth regulator. The odorous filter sludge becomes the odorless powdery or granular fertilizer, so the technology solves the problem of environmental pollution caused by the filter sludge, and has obvious economic and social benefits.
