Research Summary: Evaluation of a Synthetic Tube Dewatering System for Animal Waste Pollution Control

Research Purpose

The objective of this field study was to evaluate the performance of a Geotube® dewatering system under field conditions by quantifying the mass removal efficiency of solids, nutrients, and metals from well-mixed dairy-lagoon slurry dewatered by this system.

Activities

A Geotube dewatering system was set-up to treat the lagoon slurry mix from the primary lagoon of a 2000-head lactating cow open-lot dairy (Fig. 1). After two synthetic tubes were filled to a height of approximately 1.5 m with …
