Ecava IGX Takes Control of Sungai Udang Sewage Treatment Plant

Ecava IGX控制Sungai Udang污水处理厂

How It Started

Sewage treatment, or wastewater treatment, is the process of removing contaminants from wastewater. The term ‘sewage’ here is referring to treatment for wastewater which primarily came from household sewage. It is indeed one of the approaches to cease the water pollution environment issues. The “produce” of wastewater is considered directly proportional to the modernization process. Thus, the rapider the global development and faster growth of population, the more wastewater to be disposed.

污水处理即废水处理，是从废水中去除污染物的过程。这里的“污水”一词是指主要来自家庭污水的废水的处理。这确实是解决水污染环境问题的途径之一。废水的“产生”被认为与现代化进程成正比。因此，随着全球经济的快速发展和人口的快速增长，需要处理的废水也就越多。

Malaysia government had established Sewerage Service Department (SSD) in 1994 to regulate the services for all the sewerage systems throughout the country. The organization is responsible to provide suitable sewerage systems to meet the sewerage effluent quality standards. By the establishment of SSD, Malaysia government aims to ensure public health protection as well as preserve of national water resources.

马来西亚政府于1994年设立了污水处理服务部，负责管理全国所有污水处理系统的服务。该组织负责提供适当的污水处理系统，以达到污水排放的质量标准。通过建立SSD，马来西亚政府的目标是确保公共卫生保护以及国家水资源的保护。

Sungai Udang Sewage Treatment Plant (Sungai Udang STP) is one of the major projects implemented in The Ninth Malaysia Plan (RMKe-9) announced by the Malaysia government, which carries the slogan ‘Raising the Standard and Quality of Life’. More than RM3 bil (around 0.75 bil USD) was spent to implement all the projects in RMKe-9 during the period of 2006 through 2010.

Sungai Udang污水处理厂(Sungai Udang STP)是马来西亚政府宣布的“第九个马来西亚计划”(RMKe-9)的主要项目之一，其口号是“提高生活水平和质量”。2006年至2010年期间，用于执行RMKe-9的所有项目的资金超过了3比勒(约0.75比勒美元)。

SCADA has been widely used in sewage treatment industry, serving to monitor and control the treatment processes in the remote and automated way. SSD, who is in charged with all the sewerage systems in Malaysia, has approached Ecava to provide the SCADA solution (Ecava IGX) for Sungai Udang Sewage Treatment Plant in year 2008.

SCADA已广泛应用于污水处理行业，以远程、自动化的方式对处理过程进行监控。负责马来西亚所有污水处理系统的SSD已于2008年与Ecava接洽，为Sungai Udang污水处理厂提供SCADA解决方案(Ecava IGX)。

Basically, the main target in this project is to provide the solution for personnels to browse the entire Sungai Udang STP in the control room. To grant this request, Ecava has designed a SCADA system which meets all the requirements by SSD.

基本上，本项目的主要目标是为人员提供在控制室浏览整个Sungai Udang STP的解决方案。为了满足这一要求，Ecava设计了一个符合SSD所有要求的SCADA系统。

As an imitation of the Sungai Udang STP operation, there are flow diagram mimics designed for influent, which consists monitoring details of tankered sludge and sludge dewatering facilities. Similarly, mimics for effluent will consist of sewage treatment facility and measuring tank facility. These process details are presented in mimic animations for better understandings and the ease of operators.

为了模拟Sungai Udang STP的运行，设计了用于进水的流程图模拟，包括油罐污泥和污泥脱水设施的监测细节。同样，污水模拟装置将包括污水处理设施和计量池设施。为了更好地理解和操作，这些过程细节都是在模拟动画中呈现的。

Other than animation diagrams, some essential data such as tank water level, are plotted as graphical trends. These plotted data will be automatically logged into database records for future assessment or presented as reports.

除动画图外，一些基本数据，如水箱水位，被绘制成图形化趋势。这些绘制的数据将自动录入数据库记录，供今后评估或作为报告提交。

Power supply to a sewage treatment plant is so important that it should trigger a critical alarm if the supply is interrupted. Therefore, Sungai Udang STP system by Ecava IGX is designed to include a power status indicator in every screens. There is also a dedicated page to indicate power availability details. There are two (2) sources can supply to Sungai Udang STP, which is from either Tenaga Nasional Berhad (TNB) Malaysia, or the power from generator purposely installed for the plant. Whenever the power supply is interrupted, alarm will be triggered for attention.

污水处理厂的电力供应是如此重要，如果供应中断，应该会触发临界警报。因此，Ecava IGX公司的Sungai Udang STP系统被设计成在每个屏幕上都包含一个电源状态指示器。还有一个专门的页面来显示电源可用性的详细信息。有两个(2)来源可以向Sungai Udang STP供电，这要么来自马来西亚的Tenaga Nasional Berhad(TNB)，要么来自特意为该工厂安装的发电机。每当电源中断时，警报器就会被触发以引起注意。
