Guangxi manganese sand characteristics and the use of points 
 First, the features: 
 Manganese sand is a strong oxidant, capable of low-cost water iron and manganese from oxidation, a catalytic activity of membrane and anti-manganese 
 Manganese sand is a high efficiency and economy in addition ferromanganese materials can be used in gravity or pressure type water treatment systems. Suitable for all types of Siphon Filter, V-filter and the type of water purifier. 
 Guangxi manganese sand and manganese pollution in the dissolved oxygen compounds increased as a catalyst between the reaction, the unique self-healing features that make the process of iron and manganese in addition to not being consumed, run do not need regeneration, the reaction generated by high iron manganese oxides easily be filtered out, and then washed to remove backwash sediment easily, that only can be restored by periodic backwash performance. In addition to iron and manganese than many other methods have a great economy, under appropriate conditions, there is no chemical costs and maintenance costs, with a high iron and manganese than efficiency. 

 Iron and manganese content of dissolved oxygen content must be more than 15%. 
 PH between 6.5 and 8.5 for the wide range. 
 Has a wide temperature range, 5 ~ 55 ℃ at normal use. 
 Good mechanical strength, long service life. 

 Second, the use of points 

 (A) of the Guangxi Manganese Redox sand and self-repair process must be involved in the corresponding reaction of oxygen. Oxygen required for the reaction from the aeration. Used in water treatment facilities can meet various types of manganese sand aeration requirements. 
 (B) produced using manganese sand iron and manganese removal equipment series can seriously polluted water in the iron and manganese and other heavy metals pollution effectively.
