Biosolids management practices are evaluated based on environmental, economic and social impacts. A consideration of increasing importance is the impact of greenhouse gas (GHG) emissions from biosolids (treated sludge). BEAM tool was developed for calculating GHG emissions from biosolids management.

Guidelines on Energy Efficiency on Water and Wastewater Utilities
These EE-Guidelines were tested by three pilot utilities, SONEDE in Tunisia, ONEE in Morocco and Aqaba Water Company in Jordan. The energy checks and energy analysis at the water supply facilities were guided and supported by German experts from Hamburg Wasser, a company with longstanding experience in energy management – and known for its strategic target to be independent from external energy inputs before the year 2020.
Introduction to ECAM
This manual offers an overview of ECAM 2.0, the Energy Performance and Carbon Emissions Assessment and Monitoring tool, to guide first-time users through the basic elements of the tool and get started with the assessment. Read here.
ECAM Methodology
This document provides a detailed explanation on the theoretical background of the second version of the web-based “Energy performance and Carbon Emissions Assessment and Monitoring” (ECAM V2) tool. The main assumptions and the key considerations that form the basis of the tool are explained. An overview of variables, performance indicators and related equations, as well as benchmark values and references are given. Additionally, the manual helps users with evaluating different scenarios for specific system configurations.

Variable Speed Drive (VSD) for Irrigation Pumping
Pumping water for irrigation can be a major expense for irrigated farms. In 2003 more than 500,000 pumps were used for irrigation, and the total estimated energy cost nationwide was over 15.5 billion dollars. Improving the efficiency of irrigation pumps has many benefits, including improving the profitability of the irrigated farm.
When a single pump is required to operate over a range of flow rates and pressures, standard procedure is to design the pump to meet the greatest output demand of both flow and pressure. For this reason, pumps are often oversized and they will be operating inefficiently over a range of duties. This common situation presents an opportunity to reduce energy requirements by using control methods such as a variable speed drive.
Variable speed pumping: A guide to successful applications.
Pumping systems account for nearly 20% of the world’s energy used by electric motors and 25% to 50% of the total electrical energy usage in certain industrial
facilities. Significant opportunities exist to reduce pumping system energy consumption through smart design, retrofitting, and operating practices. In particular,
the many pumping applications with variable-duty requirements offer great potential for savings. The savings often go well beyond energy, and may include improved performance, improved reliability, and reduced life cycle costs. Most existing systems requiring flow control make use of bypass lines, throttling valves, or pump speed adjustments. The most efficient of these is pump speed control. When a pump’s speed is reduced, less energy is imparted to the fluid and less energy needs to be throttled or bypassed. Speed can be controlled in a number of ways, with the most popular type of variable speed drive (VSD) being the variable frequency drive (VFD). Pump speed adjustment is not appropriate for all pumping systems, however. This overview provides highlights from Variable Speed Pumping — A Guide To Successful Applications, which has been developed by Europump and the Hydraulic Institute as a primer and tool to assist plant owners and designers as well as pump, motor, and drive manufacturers and distributors. When the requirements of a pump and system are understood, the user can consult this guide to help determine whether variable speed pumping is the correct choice. The guide is applicable for both new and retrofit installations and contains flowcharts to assist in the selection process.
