Introduction

Stabilization ponds are the simplest method of wastewater treatment that exists. They consist of shallow excavations surrounded by earth embankments. Generally rectangular or square shaped. Stabilization ponds, also called oxidation ponds are deep reservoirs of between 1 and 3.5 meters and are intended to stabilize the organic matter present in wastewater.

This type of treatment is used extensively in small and rural communities for their flexibility, low cost of investment, operation and maintenance, is an alternative to the conventional wastewater treatment.

The classification of these gaps of treatment depends on factors such as retention time, organic loading per unit area, stabilization process (aerobic, anaerobic or mixed), and depth the lagoon, etc.

Overall gaps can be classified as stabilization ponds if this is the first step of treatment of wastewater, or as oxidation ponds, where the gaps are one after another previous step treatment process.

Oxidation ponds: Recycling water.

What is it used for?

The lagoons have the following objectives:

1. Remove residual water which causes the organic matter contamination.

2. Eliminate pathogens that pose a serious health hazard.

3. Use their effluent for reuse for other purposes, such as agriculture.

How is the project in financial terms?

There are several ways to design and build oxidation ponds, which in some cases can be very costly in terms of maintenance, cleaning, and continuity, but through basic concepts of chemistry, microbiology, mathematics in the service of the engineering accompanied of hydrological study, have combined different methods which minimize costs and make them more efficient.

Later, you can appreciate the different methods for performing these ponds and as through engineering has become a way not only to improve not only water quality, but also reduce treatment costs and help the environment.
