Engineering student discovers filtration apparatus made of fruit peels to Clean Bellandur lake water


An engineering student claims that he has devised a filtration plant made out of fruit peels which can improve the deteriorating condition of Bengaluru’s Bellandur and Varthur lakes.

Bengaluru: It has been almost two years since Bengaluru’s Bellandur lake first caught fire owing to the high amount of pollutants in it. Little has been done by concerned bodies to remedy the sorry state of affairs revolving water bodies in the state of Karnataka. Just last week, the National Green Tribunal (NGT) issued a stay on a fine of Rs 500 crore on the state government and the Bruhat Bengaluru Mahanagar Palike (BBMP) for failing to improve the deteriorating condition of Bellandur and Varthur lakes. However, an engineering student has come up with a rather ingenious method to give lakes such as Bellandur a new lease of life. The young man in question, Pawan, claims that he has devised a filtration process using fruit peels which can be used to filter the water in polluted lakes.

According to what Pawan told media outlets, his discovery was tested at the Karnataka State Pollution Control Board (KSPCB) lab and yielded positive results. One litre of water taken from Bellandur lake when treated with this filtration process was deemed fit for domestic use except as drinking water. The PH levels of the water also came down considerably after being treated.

A survey done by the Horticultural department of the government of India has stated that as many as 3.98 tonnes of fruit peel waste is generated every day in this country. “We can install 7-6 filter beds which can be changed every 5-6 days,” said Pawan adding that the used-up filters can be recycled and used as manure.

However, certain questions regarding the filtration process including its effect on the biological and chemical demand of oxygen in the lake water are yet to be answered. Since the filtration process is a tertiary treatment of water, its quality to rid the water of nitrogen and sulphates is yet to be established.
