Arsenic is an element that occurs naturally in rocks and soil and is used for a variety of purposes within industry and agriculture.It is also a byproduct of copper smelting, mining, and coal buming. Arsenic can enter the water supply from natural deposits in the earth or from industrial and agricultural pollution.Once released, arsenic remains in the environment for a long time.The reason why arsenic in groundwater needs to be treated is related to human health.Any industrial and manufacturing process utilizing groundwater that contains arsenic needs to treat the water, as it relates to the influent, recycle and reuse requirements.It can be removed from water by using an ion-exchange method-ion exchange arsenic removal using Strong Base Anion resin.
Lanlang ®TA306D is designed for arsenate and arsenite removal.
Aside from lon-Exchange method, Arsenic can also be reduced by using a Reverse Osmosis system. As we all know RO systems can take out up to 99% of Total Dissolved Solids from the water and it will take out Arsenic just like any other ions.In this reasons that some project just needs to have a Selective lon Removal method as they might just need to take out Arsenic or Sulfate specifically from the water and not remove the other ions. Since the concept of this IX is just like running a softener system, the cost of operations and maintenance is lower compared to using the hyper filtration method like the
RO or UF in the process.
