•The advantages of using this method to remove HM from waste water are the capacity to remove most of the metallic ions,that the precipitates are chemically stable and,being ferromagnetic,can be magnetically removed.The efficiency of the purification process depends on the capacity to incorporate the metallic ions to the ferrite structure,grain size,its magnetization level and the design and field gradient of the magnetic filter.The the bigger the grain size and magnetization level,the higher the removal efficiency of the magnetic filter.The characteristics of the final product will depend on the formation conditions .By controlling these parameters it is possible to obtain an increase on grain size and magnetization levels .The parameters that promote growth of grain size have been identified as high neutralization rate and slow mixing velocity,aging period and •[Fe+3]/[Fe+2] rate of 2:1.
•The work was carried out making two series of laboratory experiences with variations on the formation parameters and the separation method.The first focused on the influence of temperature,aging period and increasing Fe+3/M+2 rate in the formation of ferrite and its magnetic properties.No control on the mixing or neutralization speed was made.The second series of experiments were made controlling all of the formation parameters mentiones before,but with out aging period and at ambient temperature •Different filter designs were used in each series of experiences.

用这种方法去除污水中的HM(查出来是一种化学物质我也不知道具体是啥.)的好处之一是能够去除水中大部分的金属离子,这些成分一般在化学性质上都很稳定并且带有很强的磁性,可以用电磁(吸引)的方法去除.这种净化措施的效率取决于其吸引金属离子使其形成晶粒大小的铁盐(简单说就是铁的化合物)的能力、磁性过滤器的磁性大小、设计和其磁场梯度.晶粒体积越大、磁性越强,磁性过滤器的效率就越高.最终产品的特点(应该指质量)取决于(磁场的)分布特征.通过控制参量就能达到增大晶粒体积和增强磁性的效果.这些能提高产量的变量被认为是高中和率和低混合率、反映达到限度的时间和3价铁离子和2价铁离子的比例控制在2:1.
实验室做了两条不同变量和方法的研究.第一种聚焦于温度、时间并提高3价铁离子和2价M离子(不存在M元素不知道是打错还是代指.)在铁盐中的比例和其磁性.并未在混合或中和速率上加以控制.第二条路径控制了前文提到的所有变量,但是不包括反应时间和环境温度.每条路径的实验中都用到了不同设计的过滤器.
