The challenge

In response to escalating urban development, the Malaysian government initiated the Langat Centralized Sewage Treatment Plant (CSTP) project in 2015. The objective was to consolidate 164 small, inefficient sewage treatment facilities into a single, modern plant capable of serving a projected population of 920,000 by 2035. This initiative aimed to enhance wastewater treatment quality, reduce pollution in the Langat River—a crucial source of potable water—and support the region’s sustainability goals.

The solution

Dewaco was selected to provide state-of-the-art sludge and scum collection systems for the Langat CSTP. In 2017 we delivered and installed 96 DEWA Chain Scraper Systems and 48 DEWA Scum Collectors for the plant’s primary clarification phase. Efficient primary clarification is important since it removes the finer solids out of wastewater and reduces the load in the next phase of the sewage water treatment.

DEWA chain scrapers are reliable, and user-friendly solutions for rectangular settling basins. What is special about DEWA chain scapers is that they can be built on top of each other in two to three layers. Our chain scrapers, known for their reliability and user-friendly design, featured a unique tensioning system that allowed for chain adjustments without draining the tanks, thereby saving time and resources. Additionally, the scrapers were constructed with corrosion-resistant materials, ensuring durability and minimal maintenance.

A reliable and efficient production process increases the customer’s competitiveness. High quality and client’s client-satisfying results were ensured through close collaboration between the sewage treatment plant and Dewaco during the project.

The Outcome

The Langat CSTP, occupying a 7.3-hectare site, became one of Malaysia’s largest and most advanced sewage treatment facilities. Upon completion, it had the capacity to treat up to 207,000 cubic meters of wastewater per day, serving a population equivalent of 920,000. The integration of Dewaco’s advanced scraper systems played a pivotal role in achieving these capabilities, streamlining sludge management processes, reducing energy consumption, and minimizing maintenance costs. Moreover, the plant’s operations contributed to improved water quality in the Langat River, supporting environmental conservation efforts.

This successful collaboration underscored Dewaco’s expertise in delivering innovative solutions for complex water treatment challenges, reinforcing our reputation as a globally recognized and trusted supplier in the industry.
