Water Purification

Water Purification through the Ecological Food Chain Effect

The BRI (Bio Reactor Island) Method uses bio-manipulation technologies to inhibit phytoplankton growth and thereby improve water quality. This method involves populating a floating island with plants and phytoplankton consuming microbes.

This island is designed to optimize the accumulation of microbes on its underside surface. A water circulation system circulates and aerates the water accelerating the rate in which phytoplankton brought into contact with the microbes under the floating island.

Minimizing Environmental Impact

In certain instances, dredging will become necessary in areas where environmentally harmful substances such as heavy metals and dioxins exist. In this respect, methods of dredging have been developed to ensure minimal adverse environmental impact when working under these conditions.

The Super Grab Bucket (SGB) Dredging Method provides a solution to remove dredged material whilst ensuring minimal water pollution when compared to other dredging methods. This method utilizes a specially designed bucket that minimizes leakage of turbid water. The bucket design is also such that over-dredging is avoided. As well as the reduced impact on the environment, this method is also cost effective in that in many instances the need to install a silt barricade or clean turbid water is minimized, thus saving costs in these respects.

Re-use of Dredged Materials

Dredged materials will invariably contain sand, silt and clay. The Soil Classification Method is utilized to extract sand from dredged material by use of a centrifugal classification system. The sand then can be re-used for construction purposes. This method is effective to reduce the amount of material to be dumped thereby mitigating environmental impact.
