luent discharge license limits; The concentrations are also lower than the ultralow 0.1 mgP/ Ortho limit that is proposed to come in to effect in 2 3. It should be noted that the model predicted savings for medium and high capital investment measures might not be realised in practice due to the universally acknowledged challenges of implementing control systems in wastewate treatment. The following is therefore recommended before practically implementing an measures in order to increase the chances of success: more detailed investigation of market av ailable options for process and aeration control as well as blower technologies and th feasibility of incorporating them into the existing plant. The quality and costs of equipment including maintenance requirements are of critical importance to the success of the aeration ECMs Application of superior economic evaluation technique such as life cycle cost analysis, which takes into account all the costs incurred during the project life, so that the most cost effective measures can be selected for implementation Further process evaluation and modelling to determine inter alia () capacity and efficiency of the existing blowers and di ffusers (including minimum turn downs and maintenance requirements (ii) impact of new sludge handling and treatment facilities on process capacity and energy requirements (iii) process configuration and control optimisation to incorporate the above Keeping records of power usage by blower and other main equipment to accurately assess the power usage and improve the cost analysis for aeration ECMs 4-3 Table 4-1: Summary of Model Predicted Feasible Aeration ECMs Units Baseline Existing Blowers Replace Module 1 Blowers Simple Advanced Process Control Simple Advanced Process Control Optimised Process Control FB Cascade NH 4+/DO FF/FB NH 4+/DO Optimised Process Control FB Cascade NH 4+/DO FF/FB NH 4+/DO A
