Hose-Drag Wastewater Equipment

By: Garry Grabow, Karl Shaffer, Sanjay Shah Field Calibration Procedures for Animal Wastewater Irrigation Equipment

Hose-drag-type equipment has gained popularity in recent years for land application of wastewater in North Carolina. It offers several advantages over traditional irrigation systems including odor reduction, nitrogen conservation, and a relatively high flow rate that cuts the application time. This publication explains calibration procedures for the “low-profile-type” discharge system and a “boom-type” system.

Poultry Waste Stockpiling Methods: Environmental Impacts and Their Mitigation

By: Sanjay Shah, Garry Grabow, Lingjuan Wang Li
