One of the method used to improve of process to give the solution to increase process standart in internal manufacturing purpose to minimize defect or non conforming and reduce waste so the trend of failure product reduced in period is six sigma method. Through of application cycles of DMAIC (Define, Measure, Analyze, Improve and Control) in six sigm, so one of problem can to clear define the root causes and can to improve with structural. This riset in PT Clariant Indonesia Tangerang Site, in Waste Water Treatment analysis costing needed to operasional water treatment in one year. Where there are several cost aloction not yet effective and efficient so occur waste of operational costing Waste Water Treatment in 2015. Result of the riset is success to defined several root causes and defined several solution to tackle problem waste of cost operational in Waste Water Treatment. In the end of riset success to reduce operational cost Waste Water Treatment till 360 mio IDR in 6 months Control phase.

Lifecycle Design

Capacity to remotely monitor and control systems for waste-water treatment and to provide real time and trustworthy data of system’s behavior to various stakeholders is of high relevance. SCADA systems are used to undertake this job. SCADA solutions are usually conceptualized and designed with a major focus on technological integrability and functionality. Very little contributions are brought to optimize these systems with respect to a mix of target functions, especially considering a lifecycle perspective. In this paper, we propose a structured methodology for optimizing SCADA systems from a lifecycle perspective for the specific case of waste-water treatment units. The methodology embeds techniques for handling entropy in the design process and to assist engineers in designing effective solutions in a space with multiple constrains and conflicts. Evolutionary multiple optimization algorithms are used to handle this challenge. After the foundation of the theoretical model calibrated for the specific case of waste-water treatment units, a practical example illustrates its applicability. It is shown how the model can lead to a disruptive solution, which integrates cloud computing, IoT, and data analytics in the SCADA system, with some competitive advantages in terms of flexibility, cost effectiveness, and increased value added for both integrators and beneficiaries.

Key Parameter

The monitoring and control of anaerobic waste water treatment is discussed. In a first section optimum biological conditions were given. These are a nutritionally balanced waste water free from oxidants and toxicants, a temperature of 55-60 °C and a pH of 6.8-8.0. In a second section, parameters for monitoring and control were discussed. It was concluded that present system designs usually allow for the control of influent flow rate and temperature but not for the key parameter solids retention time (SRT). Process control in anaerobic waste water treatment, therefore, is more monitoring than control, a situation that is unsatisfactory.

And Control

To an ever-increasing degree, it is nowadays demanded of treatment plants that they eliminate nitrogen and phosphorus from the waste water. Of the 81 treatment plants operated by the Lippeverband, a large number even now eliminate nitrogen although the percentage eliminated is still not optimal since, until recently, N elimination was still predominantly considered from the point of view of economy and stabilization of the degradation process. A further increase is definitely possible by means of an improved process and control technology. Phosphorus elimination can also be largely effected biologically. One of the plants provided with denitrification stages was appropriately retrofitted for this process. The results after two years of operation show that an optimum treatment efficiency can be achieved with a plant of this type.
