This is because high concentrations of toxic heavy metals in the sludge often cause environmental problems and affect lands for agriculture (Kim et.al. 2005). Therefore, pre-treatment of sewage sludge is required in order to get rid of the environmentally toxic heavy metal (Kim et.al. 2005).

Heavy metal removal from inorganic effluent can be achieved by conventional treatment processes such as chemical precipitation, ion exchange, and electrochemical removal. These processes have significant disadvantages, which are, for instance, incomplete removal, high-energy requirements, and production of toxic sludge ( Eccles, 1999 ).

Mercury is one of the most toxic of heavy metals, and once in the soil it is soaked up by grass, which is eaten by cows, which are eaten by … you get the idea. Farmers are now growing maize and canola plants in the area, though, which soak up heavy metals quite nicely – gold as well as mercury.

Toxic waste in the oceans includes industrial waste, sludge, and radioactive waste. Around 10 percent of all dredged materials are polluted with heavy (and toxic) metals like cadmium and mercury. When these materials find their way into the oceans, it will directly affect marine wildlife that could die or suffer harmful consequences.

Heavy metals are present in ground water and are usually Nickel, Lead, Cadmium and Zinc. These metals are present in water at ppb level under cationic form such as Zn 2+ , Ni 2+ , Cd 2+ and Pb 2+ . Reverse Osmosis can be performant at removing low level of heavy metals, although in aerobic conditions metal oxides can clog the membranes.

Introduction. Heavy metals are defined as metallic elements that have a relatively high density compared to water [].With the assumption that heaviness and toxicity are inter-related, heavy metals also include metalloids, such as arsenic, that are able to induce toxicity at low level of exposure [].
