The industrialization has led to the environmental pollution and pollutant removal from waste water is intensively studied.Cadmium is used for production of dye, pigment, batteries, ceramics, wooden and plastic products. The metal is also used in electroplating, semiconductors, rectifiers and solder for aluminum. Smelters produce one million kilogram of Cd which is released in to the atmosphere every year.

There are lots of mentors available now. For the developing countries brick clay is very good.

Yes, However the capacity remove metals and fluoride, etc., are very low in pieces of brisks, due to limited surface area available for adsorption.
(a personn who works (and developing new cot-effective methods) with water purification methods in developing countries for two decades).
Hello,
There are various techniques but using Red Mud (an Aluminium Industry Waste) is a simple, cost effective, efficient and eco-friendly method for the removal of Cd, Pb and other heavy metals from waste water.
hello
this link below could be help

Due to the recent revisions to the Japan Water Pollution Control Act to reduce the permitted cadmium content in wastewater from 0.1 mg / l to 0.03 mg / l.
Japan has introduced a new technology for cadmium removal, mainly chemical processing and ultrafiltration technologies.
Reverse osmosis is an effective (but little expensive) way to remove most heavy metals from contaminates water.
