Hydro International has launched an industry tool to help assess the full operating cost impact of grit deposition and abrasion on plant efficiency.
The Cost of Grit Calculator has been developed for use as a universal online resource for engineering designers and water and wastewater treatment plant operators.
It is designed to draw on real-world data collected from operating plants.
The data can be used to predict the likely efficiency savings that can be gained for any operator installing a high-performance grit removal system, using the guiding principles of Advanced Grit Management, Hydro International said.
The calculator requires the input of a small number of values to generate an estimate of the annual and lifecycle savings that could be made by removing more grit at the headworks.
Research shows that poor grit removal is a major source of avoidable process inefficiency, operating, maintenance and replacement costs, Hydro International said.
Having set the operating plant capacity and the preferred equipment lifetime cost into the system, operators can input estimated or known costs of their downstream plant maintenance activities.
