Chapter 2. TECHNOLOGICAL ASPECTS OF EUTROPHICATION CONTROL

Introduction

This chapter focuses on possible solutions to the eutrophication problems presented in Chapter 1. The solutions include methods to remove nutrients from wastewater and from non-point sources, techniques to reduce emissions at the source and methods to improve eutrophic lakes and reservoirs. Technological and cost-moderate approaches, which are directly applicable to developing countries, are emphasized. Guidelines, incorporating decision-making trees, are offered on how to select a solution to a specific environmental problem.

Important recommendations are as follows:

• Expect that a successful strategy will require several approaches.
• Expect that effective management will require the application of a combination of technologies.
• Set up an environmental management plan at an early stage.
• Consider prevention instead of correction, as ecosystem restoration is often costly.
• Proper ecological knowledge of the ecosystem is a prerequisite for sound environmental management.
• An optimum solution can only be found if the entire watershed is considered.
