Food grade polyaluminum chloride, also known as drinking water grade polyaluminum chloride, referred to as PAC, is an efficient, safe and environmentally friendly water treatment agent, widely used in drinking water purification, sewage treatment, industrial water treatment and other fields. The following is a detailed introduction to food grade polyaluminum chloride:
1. Basic characteristics
Komposisi Kimia: Gred makanan polyaluminium klorida adalah sebatian polimer bukan organik yang diperolehi oleh sintesis saintifik garam aluminium dan aluminium klorida, dengan ciri-ciri tidak berwarna, tidak enak, tidak toksik.
High purity: Its purity is very high, the alumina content is about 30%, not less than 29%. Kesucian yang tinggi bermakna kandungan kekotoran dalam produk sangat rendah dan tidak akan menjejaskan kualiti air selepas rawatan.
Tahap pempolimeran yang tinggi: Berat molekul PAC gred makanan adalah sehingga berjuta -juta, dan tahap pempolimeran yang tinggi membolehkan molekul PAC dengan cepat membentuk bunga alum yang stabil di dalam air, dengan berkesan mendakan dan menghilangkan kekotoran seperti bahan yang digantung, koloid, dan bahan organik .
High solubility: easily soluble in water, the formed solution has good stability, which helps to improve the efficiency of water treatment and reduce the production of sediment.
Low sediment content: Compared to conventional coagulants, food grade PAC has a lower sediment content due to its high purity, high polymerization and excellent solubility.
2. Bidang Permohonan
Drinking water purification: In the field of drinking water purification, food grade polyaluminum chloride plays a vital role. It can quickly purify the water, remove the suspended matter, colloids, organic matter and other impurities in the water, and also kill a certain number of bacteria and viruses to ensure the safety of people's drinking water.
Sewage treatment: In terms of sewage treatment, food-grade polyaluminum chloride also performs well. It can effectively treat pollutants such as suspended matter, organic matter and heavy metal ions in domestic sewage and industrial wastewater, reduce turbidity and chroma of sewage, and improve water quality.
Industrial water treatment: In the field of industrial water treatment, food-grade polyaluminum chloride is widely used in papermaking, textile, printing and dyeing, chemical and other industries. These industries will produce a lot of wastewater in the production process, which contains a lot of suspended matter, organic matter and chroma and other pollutants. PAC dengan cepat dapat bergabung dengan bahan pencemar ini untuk membentuk floc dan mendakan ke bawah, untuk membersihkan kualiti air dan memenuhi keperluan kualiti air pengeluaran perindustrian.
