Product Description:
We start by crushing the raw coal, then extracting it with a sodium hydroxide (NaOH) solution in a reaction tank at 90°C for two hours. After removing unreacted impurities, the pure sodium humate solution is fed into a drum dryer. The solution forms a thin film on the drum wall, which is instantly dried into a flake, then peeled, cooled, and screened. This process yields a glossy, black product with low impurities. Our closed-loop system for condensate, dust, and exhaust gas recovery ensures a clean, efficient, and eco-friendly production line.

Applications:
Sodium humate is a powerful tool for aquaculture water quality management. It acts as a "master conditioner" by significantly reducing harmful substances in the water.
1. Purifies Water: Sodium humate actively adsorbs residual feed and fish waste, effectively lowering concentrations of toxic compounds like ammonia nitrogen and hydrogen sulfide. It also chelates heavy metals, neutralizing their harmful effects on aquatic life.
2. Controls Algae Growth: Its unique shading properties turn the water dark, creating a "natural killer" effect on unwanted algae. This black-water effect effectively inhibits the growth of moss and cyanobacteria, preventing dangerous algal blooms.
3. Maintains a Healthy Environment: Beyond purification and algae control, sodium humate also helps to detoxify water by degrading harmful substances. It adjusts pH levels to a more stable range, ensuring a healthier and more balanced living environment for fish, shrimp, and crabs.
Aquaculture (based on a water depth of 1 m, other water depths increase or decrease proportionally)
| Objective | Dosage (hectares·m) | Usage points | Frequency |
| Water purification and oil removal film | 15-30 kg | Sprinkle 20-50 times with water and use in the morning on a sunny day | Once every 10-20 days |
| Shading/heat reduction | 30-45 kg | Sprinkle evenly throughout the pool | Depending on transparency, refill once every 5-7 days |
| Change the bottom and deodorize | 15-30 kg | Direct dry sprinkling, old ponds and thick bottom mud should be used with caution | Once every 7-15 days |
| detoxification
(heavy metals, algae toxins) | 30-60 kg (double when worsens) | After sprinkle, turn on the aerator, and it is better to use beneficial bacteria | Once every 1-3 days, depending on the poisoning |
| Make the water body fertile and replenish carbon | 7.5-15 kg | Mix with photosynthetic bacteria, molasses, etc. and sprinkle | Once every 7-10 days |
| Mitigating red tides and algal blooms | 7.5-30 kg | Use 2 times 2-3 days apart | Depends on the condition of the algae |
