Аннотация:
Fosfatlashda ishlatiladigan kimyoviy moddalar natijasida chiqindi suv quyidagi komponentlarni o‘z ichiga quyidagi tarkibga ega :ortofosfatlar, pirofosfatlar, metallar fosfatlari (Fe, Zn, Mn, Ni),erigan og’ir metallar (Zn²⁺, Ni²⁺, Fe²⁺/³⁺, Mn²⁺),pH darajasi odatda kislotali (2-5 oralig’ida),yuzaga chiqadigan loyqa (fosfat cho’kindilari),yuzaga chiqadigan emulsiyalar (agar yog’li moddalar ishtirok etsa)Tajribalar asosida Ohak (Ca(OH)₂), natriy gidroksid (NaOH) yoki ammiak qo’shib pH ni 8.5–9.5 gacha ko’tariladi va suyuq kompleks o`g`it olindi.
