In the second stage, diatomite is added to the heated sewage sludge in an amount of 0.25 to 1.5 kg per 1 kg of dry mass of sewage sludge and mixed. In the third stage, the granulate is formed, and in the fourth stage the granulate is dried at a temperature of 60°C to 85°C for 30 to 60 minutes, and then in the fifth stage the granulate is crushed.
  • the method of producing organic-mineral fertilizers is carried out using sewage sludge from mechanical-biological sewage treatment plants.
