Practical Wastewater Optimization
Elements in simultaneously achieving lowest cost and highest efficiency from wastewater treatment systems can be drawn on singly, or for maximum effectiveness, integrated within a comprehensive improvement plan:
Process Control Optimization- Liquid/Sludge
Process control optimization is built on developing a solid understanding of process data and operating conditions, trending data, evaluating key historical events, reviewing key process indicators, evaluating tradeoffs, key factors effecting sludge volumes and quality, considering energy, chemical and sludge costs, staff capabilities, and developing an implementable improvement plan.
Staffing/Outsourcing Optimization
Optimization considers organization, shift scheduling, operating approaches and division of labor, off shift and emergency response needs, vulnerability analysis, and risk management. Many staff needs can be met through outsourcing including lab, instrumentation and SCADA maintenance, grounds maintenance, and etc. Planning can consider baby boomer impacts and elements of labor costs and productivity including time off and benefit costs for full and part-time staff.
Energy Balance and Optimization
An energy balance for all significant motors in the facility needs to be calibrated against electric bills and adjusted to fit actual operating practices over a range of events. Once completed the balance can be used to model and predict outcomes of proposed operational modifications. Review of bills will indicate whether demand charges and off peak and seasonal strategies will be practical as well as .

Wastewater Cost and Effluent Optimization
A chemical balance looks at chemical use in the context of process control goals and strategies. Sludge production as a function of chemical dosage is an important consideration. Alternate chemicals should be considered where benefits such as lower cost, lower sludge production or more readily dewaterable sludge might result. vendor tests on site can be useful to assist in optimization efforts.

Equipment and CMMS Assessment and Optimization
Equipment assessment considers operating condition, vulnerability to breakdown, maintenance effectiveness, cost-savings or proess enhancement opportunties from changes in operating strategies or replacements. The CMMS (Comprehensive Maintenance Management System) review looks at PM/CM balance, effectiveness, and deployment of staff for maintenance.
Assessment of Management Systems, Staff Capabilites & Planning
SOP's, use of logs, emergency response, management reports, monthly and annual planning and staff application of these systems are all factors in assessing overall management. Assessment of recruiting needs is useful in assessing the management systems needs, training needs assessment, and recruiting demands and priorities.
