First, the PAC iron making process - two-step method: This production method commonly used two-step method of acid production process at atmospheric pressure and a certain temperature, the first step to adding a higher ratio of hydrochloric acid powder bauxite, alumina dissolution PAC as the manufacturer, the second step is the first step of the supernatant calcium aluminum powder react with new entrants. This step dissolution of both the PAC 30% alumina, but also can adjust the basicity. The first step can be dissolved alumina typically more than 80% of PAC, the second step of the aluminum dissolution rate of 50% or less, it is typically the second stage precipitation slag into the first reaction to reflux. With bauxite and aluminum calcium powder as raw material, the use of two-step process roller acid chloride, prepared alumina mass fraction of 10.11%. Basicity of 85% liquid ferric chloride products. Second, the PAC iron making process - acid method: the liquid product obtained PAFC calcium aluminum powder directly with hydrochloric acid to adjust the basicity and cured after completion. The process is simple, low investment, easy operation, low production cost, but the product of insolubles, high heavy metal content, the solid product is usually not high alumina content. The mass fraction of about 28%, poor product appearance, high iron content. Acid was prepared by PAFC. The main difference ★★ spray PAC standards and tumble PAC ★★ next 10 years PAC (PAC) is still my life inside and outside the dominant drinking water purification products, raw materials will be extensive use of hydrogen alumina. High purity products tend to ensure the health and safety of drinking water drinking water quality standards to rapidly improve. I had a habit of using the water industry should change the concept of low quality cheap PAC (PAC) of the product. To ensure that PAC (PAC) of the health and safety into the drinking water coagulant market companies will adopt certification standards system. 28% of PAC, PAC Huangpu District, Saatchi Saatchi water provided by the water purification materials Co., Ltd., Henan. 28% of PAC, PAC Huangpu District, Saatchi Saatchi Henan water purification Material Co., Ltd. (www.gyssjs.com) this year introduced a new upgrade, the above picture is for reference only, please call this page or Tel picture on to obtain the latest information, Contact: Zhang.
