Green Bridge

Green Bridge technollogy by Green Water Revolution Pvt Ltd is an in-situ bioremediation and phytoremediation based constructed wetland for restoration of drains and rivers.

Green Bridge technology uses the filtration power of biologically originated cellulosic/fibrous materials in combination with sand, gravels, and the root systems of green plants. It’s an innovative approach that minimizes the cost of pollution treatment. The cellulosic/fibrous materials, like coconut coir, dried water hyacinth, or aquatic grasses, are compacted and woven to form a bridge/porous wall-like structure that is strengthened by stones and sand. All of the floating and suspended solids are trapped in this biological bridge and the turbidity of flowing water is reduced substantially. The green plants growing there help absorb soluble substances including heavy metals.

Natural streams, rivers, and lakes have their own built-in purification system, consisting of wind, natural slopes, stones for biological growth, and complex food webs. The “food web” is the utilization of one organism’s waste by another as its food. Nature has her own living machinery of detritivorous microbes and other living species that consume wastes. These principles have been harnessed in the treatment of polluted streams.

Experts say, “There is no recurring expenditure and one doesn’t need any skilled maintenance force. Unlike conventional mechanical process of cleaning up a river, the process is bio-degradable and bio-absorbing.”

The scheme involves the application of ecological engineering to remove organic and inorganic pollutants from the water and utilizes them as nutrients in the ecological cycles. The Green Bridge is developed by using filtration power of cellulose/fibrous materials with stones. All the floatable and suspended solids are trapped in this biological bridge and the turbidity of flowing water is reduced. Green plants on the bridges increase the DO level in water, which in turn facilitates the growth of aerobic organisms, degrading organic pollutants.
