印度尼西亚巴厘岛帕特诺水处理厂

印度尼西亚是世界第四大人口大国,为满足其城市人口和各种工业日益增长的需求,基础设施正在迅速发展。印度尼西亚的巴厘岛是世界上最受欢迎的旅游目的地之一,其水利基础设施正在迅速发展,以满足其旅游业日益增长的需求。为了满足巴厘岛东南海岸沙努尔海滩度假胜地不断增长的用水需求,印度尼西亚政府公共工程与住房部(PU)计划建造新的帕特诺水处理厂。印尼国有建造商PT Waskita Karya (Persero) Tbk承建了该工厂。

帕特诺水处理厂致力于将印度尼西亚的供水业务提高到一个新的水平。引入了仪表和自动化技术,以提高其操作责任感以及对操作员的管理。SCADA系统为实现这一目标提供了适当的措施。帕特诺水处理厂于2014年5月开始商业运营,每秒生产300升(约25,920立方米/天)的饮用水。该工厂将逐步提高产量,为巴厘岛南部的三个直辖市(吉安亚尔、登巴萨和巴东)提供饮用水。

公共工程与住房部(PU)和Waskita Karya选择横河电机的过程自动化系统作为一站式解决方案,其中包括FAST/TOOLS™ SCADA (监控和数据采集)系统、基于STARDOM™网络的控制系统以及各种现场仪表。为了满足紧急的市场需求,PU和Waskita Karya要求横河电机印尼公司在订购后的三个月内交付这些仪表和系统。此外,PU和横河电机致力于为帕特诺水处理厂操作员的能力提高提供支持,特别是运行和维护SCADA系统方面的能力。

过程概述

帕特诺水处理厂利用来自河流的地表水,为大众消费者生产饮用水。进水口中的原水经过曝气和预沉淀,重颗粒沉降到底部。然后,带有悬浮污垢和颗粒的水进行沉淀,它们与明矾或其他化学物质凝结成一团,使其依靠重量沉到底部。沉降的颗粒和团状物被移至污泥干燥床。然后将水过滤,并添加氯气对水进行消毒。最终,经过处理的水进入水库,输送给消费者。

客户面临的挑战和我们的解决方案

横河电机印度公司执行了从产品供应到工程、安装和调试的整个项目的整体解决方案。

PU熟悉巴厘岛现有水处理设施中的常规面板操作。然而,对于帕特诺的新水处理厂,PU决定采用最新的可靠控制系统,以提高可用性和操作质量,并提高维护的便利性和未来的扩展性。对他们来说采用新技术的决定是一个巨大的挑战。自2014年5月帕特诺水处理厂开始运营以来,该厂一直在为巴厘岛西南地区提供安全、清洁的水。在这一成功的背后,客户和横河电机印尼公司都做出了巨大的努力,克服了重大的挑战以实现目标。

1. C集中操作

To satisfy the PU expectation of acquiring the latest most reliable control system available, Yokogawa Indonesia provided FAST/TOOLS™ SCADA (supervisory control and data acquisition) system and the STARDOM™ network-based control system with field instruments. The major field instruments include pH analyzer, turbidity analyzer, chlorine analyzer, magnetic flowmeter and pressure transmitter as well as other associated field instruments in the process monitoring of water intake, pre-sedimentation, chemical dosing and reservoir. These instruments have LCD operation panel for easy parameter setting and for prompt operation at site.

STARDOM Network-based Control System

STARDOM™ Network-based Control System

The main process of a water treatment facility uses many pumps and motors. To increase reliable control of the operation, STARDOM™ provides dual redundant configuration in dual control CPUs, power supplies and communication networks. All STARDOM™ controllers are connected to FAST/TOOLS™ SCADA system at the central operation room through the Ethernet network. As compared with PU existing conventional panel operation in Bali, FAST/TOOLS™ provides more sophisticated and flexible operation by integrating with process data, equipment status, alarms, messages, trending, process reports, and historical data and system maintenance information. With this control system, the Petanu water treatment plant is achieving secure, stable and reliable operations in the entire process with a minimum number of operators.

2. Local Engineering Support

It was the first time for both PU and Waskita Karya to work with Yokogawa Indonesia for their water treatment plants. In addition, PU and Waskita Karya requested short delivery of the system. To satisfy customer's expectation and get their confidence, Yokogawa Indonesia used their experience, knowledge and local engineering skills of infrastructure plant projects in Indonesia and carefully verified and applied the control logics and operation screen designs into the control system.

3. Sophisticated Operator Training

For the customer's smooth start-up of SCADA based operation, Yokogawa Indonesia gave customized training for PU at both Jakarta and Bali so that they could get accustomed to the graphic screen operation in advance. Through the training, PU became confident and adapted to SCADA operation before the plant commissioning.

This sophisticated operator training prepared operators for any unusual operations, such as a sudden flow-rate change at the water intake due to heavy rain, so they can adjust the water inlet flow accordingly.

Once the operators obtained the benefits of SCADA system, they extended their operation to be more flexible and efficient.

Customer Satisfaction

"We are very satisfied with the successful installation and smooth operation on schedule. The water demand in this area was very critical. So sooner water supply was definitely required. We appreciate Yokogawa Indonesia's commitment and sophisticated services for this project. It was the first time for us to use Yokogawa control system. However, thanks to Yokogawa Indonesia's local efforts and supports, we are now very confident to use the state of art technology and reliable products. With Yokogawa control system, we can operate the plant more efficient with less manpower than conventional panel operation. Now Petanu water treatment plant has become a showcase of water treatment plant in Bali. We want to utilize this facility as a training center for future operators contributing to increase the quality and efficiency of water production. We are very proud of supplying safe and clean water to our region 24 hours /365 days constantly", said, Mr. I Gusti Alit Joni, a Head of Water Supply Management Unit of Bali.
