Ihaka Waste Management System
Design Overview
Drip irrigation system delivers nutrient rich liquid waste to banana trees
The Ihaka waste management system utilizes water to clean the pens. The waste water from the pens flows into a tank that contains a large filter bag. The solids are retained in the filter bag while the liquids are allowed to pass. After passing through the filter bag the liquid waste is pumped into a elevated storage tank that gravity feeds a drip irrigation system delivering the nutrient rich liquid waste to a crop field. The solids remaining in the filter bag undergo an aerobic treatment process that yields compost.
How It Works
On a daily basis the pens need to be cleaned with water. To minimize the amount of water necessary, it is recommend that the solids be scraped into the waste canal before cleaning the pens. Using a pressure washer will also help reduce the amount of water necessary. Every 8 to 9 months the filter tank will become full at which time the flexible hose feeding the filter tank needs to be repositioned to the empty tank. This period between filter tank cycles allows the solids in the filter bag enough time to breakdown
