Dried fish scales for removal of heavy metals from effluent water waste. (Biosorption)
Dried fish scales can possibly be used in removal of heavy metals like lead, chromium, arsenic from effluent waste water. Fish scales are considered as a good bio adsorbent and are environment friendly and easily available.

Our contribution to a clean environment – Waste(effluent water) management using other waste(fish scales)!
Fish scales are widely understood as a waste element. The scales are separated from the edible parts of the fish and have a lesser known, but tremendously valuable use. Big energy industries like coal power plants, petroleum and gas plants, also battery makers and the tanning industries face a big challenge of treating their effluent waste which has high concentration of heavy metals.
Sources of such high concentrations may be geologic, synthetic or generated as a by- product of energy production. These heavy metals are very toxic and extremely deleterious to humans, plants, and animals.
Application of fish scales to remove heavy metals is a very recent innovation and can be considered as one of potential biosorbent for heavy metals. It is an environmentally appealing and economically attractive alternative to current heavy metal adsorbing materials. Dried fish scales can possibly be used in removal of chromium, arsenic, lead etc.
Recently, adsorption of heavy metals and specifically arsenic using natural materials or waste products from various agricultural and marine operations have emerged as an option for developing economic and eco-friendly waste treatment processes. Using fish scales as adsorbent can help remove the heavy metal cations considerably.
As per the research and studies carried out worldwide, a number of fish scales namely, Labeo Rohita, Catla catla and Atlantic Cod have been reported and give promisising result world wide.
Tilapia fish scales has a potential to use as biosorbent for heavy metals removal in aqueous solution. Among other heavy metals, zinc ion reached the highest removal with 92.3%. This removal was achieved at pH 6, biosorbent dose 0.02g, 10ppb concentration and 3 hours contact time.
