Introduction to Operation OASIS

The massive waste water problem that currently pollutes our bathing waters costing £billions to process throughout the world can be used to irrigate and reforest desert coastlines to induce rainfall.

Our aim is to use the return ballast capacity of super crude carriers which currently transport sea water half way around the world at great financial and environmental cost. This ballast is discharged into the sea, often introducing invasive marine species which affects the stability of indigenous species of flora and fauna.

The E.U. is legislating against this practice and tanker operators will be forced to seek an alternative.

Operation OASIS offers an exciting opportunity for ballast water. Transporting treated waste water to irrigate and reforest arid coastlines to induce rainfall has to be the way forward.

One tanker loaded with 300000 cubic meters of treated waste water would support 57 hectares of forest for a whole year.

Reclaiming deserts to enable people to feed themselves and grow great forests will offset the carbon emissions from shipping.

With global food shortages upon us we are already feeling the strain on our pockets in the developed world and renewable resources are in rapid decline. Drought is affecting all major food producing countries and wells are running dry. Water scarcity poses major problems for us and our children. We need to act fast in order to avert a major global catastrophe.

When the mighty river Amazon dries up and it's fish stocks die it is time to take stock on how we manage our fragile environment. For more detailed information visit our website and forum at: http://www.operationoasis.com

Abstract
We investigated the effects of the application of wastewater sludges on microbial degradation of crude oil. the experiments were carried out in four beach simulating tanks. In each tank, filled with gravel and seawater, crude oil was added on the surface of seawater. Dehydrated-wastewater sludge, liquid-wastewater sludge and synthetic fertilizers were added in tanks A, D and C, respectively. In tanks A and D, sharp increases in the bacterial number and the oxygen consumption occurred immediately while the increases in tank C was slower. The concentration of nitrogen was high during first few weeks and later decreased in tanks A and D. The synthetic nitrogen fertilizer was maintaining the nitrogen concentration above 1 mg l-1 for the whole experimental period. These observations indicated that the effect of the synthetic nitrogen fertilizer was more enduring than those of the liquid and dehydrated sludges. However, higher concentrations of phosphorous were supplied by both the liquid and dehydrated sludges than by the synthetic phosphorous fertilizer. No significant differences were observed between the biodegradation rates of crude oil in each amended tank. Thus, it was concluded that the wastewater sludges are useful as fertilizers for crude oil bioremediation.
