Fertilizers

Optimize phosphate rock washing, acid clarification, and dewatering with advanced filter media for fertilizers, to improve productivity, reduce costs, and enhance sustainability.

Durability Meets Clarity in Fertilizer Filtration

Yield and purity
Achieve low-solids and optimal separation with high-performance filter media engineered for phosphoric acid and potash processes.
Higher lifetime
Chemically resistant and thermally stable filter media maintain performance in abrasive and corrosive environments.

Suitable Solutions for Every Process Step

In the processing of phosphoric acid and potash, handling fine particles and corrosive slurries is required. Continuous operation poses a challenge to filter performance, maintenance, and environmental compliance.

Sefar provides durable, high-performance filter media tailored to each step of fertilizer production. These advanced solutions handle fine particles and corrosive slurries, reduce downtime, improve acid clarity, and support efficient, reliable, and environmentally compliant operations.

Phosphate rock beneficiation and washing
Phosphate rock must be washed to remove clays, silicas, and fines. Sefar filter belts provide high washing efficiency and consistent dewatering in continuous operation.
Phosphoric acid clarification
Precise separation of gypsum and acid is important for product quality. Our filter cloths support hemihydrate and dihydrate processes with high chemical resistance and clarity.
Dewatering
Efficient dewatering reduces handling and disposal costs. Sefar belts deliver fast drainage, low residual moisture, and excellent mechanical stability.
