Fort Cornwallis, located in Penang, Malaysia, is a historical landmark that attracts thousands of tourists every year. Built by the British East India Company in the late 18th century, the fort was initially constructed as a defensive structure to protect the island from potential threats by sea.
Although it never engaged in battle, Fort Cornwallis has become an enduring symbol of Penang’s rich history, offering visitors a glimpse into the colonial era through its well-preserved walls, cannons, and exhibits. Today, it serves not only as a historical site but also as a cultural attraction, becoming part of the UNESCO World Heritage Site in July 2008.
Best of all, the site would have its moat to be fully restored to its former glory by the end of 2024. Previously, the moat had many key issues that needed to be addressed to improve water quality and hygiene.
Water Quality & Hygiene Issues at Fort Cornwallis
An overgrowth of algae can be spotted in the moat. The active and uncontrolled algae growth in the moat had resulted in negative impact towards the historic site.
The algae overgrowth can accelerate the degradation of the moat’s walls and surrounding structures. Algae can trap moisture against the walls, promoting the growth of mould, moss, and other organisms that can weaken the masonry over time.
Additionally, the presence of thick algae can detract from the visual appeal of Fort Cornwallis, negatively impacting its status as a historical and tourist site. Visitors may find the sight of the algae unappealing, which could diminish their overall experience.
Uncontrolled algae growth can lead to many more adverse outcomes such as health hazards, foul-smelling odours, and eutrophication, where a depletion of oxygen causes the death of other organisms in the local ecosystem.
Solution: LG Sonic E-Line at Fort Cornwallis, Penang
To improve the water quality, the LG SONIC E-LINE was installed in the moat to prevent the growth of new algae. It can control algae without harming the ecological balance in the moat.
Effective Algae Control Using the LG SONIC E-LINE
How does the LG SONIC E-LINE work to control algae? This system harnesses ultrasound technology to offer an eco-friendly method for managing algae in ponds. The E-LINE effectively targets and controls algae in smaller water bodies using precise ultrasonic frequencies. Its innovative design ensures both safety and efficiency in controlling algae.
The solution was to install one or multiple systems that transmit specific ultrasonic parameters depending on the type of algae.
The devices emit low-power ultrasound waves in the top water layer, generating a constant pressure cycle around the algal cells. This interferes with the algae’s buoyancy regulation, preventing them from accessing sunlight and nutrients. As a result, the algaes are unable to perform photosynthesis. Thus, they sink to the bottom, where they decompose naturally without releasing harmful toxins. Throughout the whole process, no other aquatic organisms, animals, or humans are harmed, ensuring sustainability and long-term benefits to the moat.
Results of the LG Sonic E-Line on Ultrasonic Algae Control
After operating the LG SONIC E-LINE, algae in the moat have been controlled and the water clarity has increased. This can be seen when the moat looks pristine and clear, highlighting Fort Cornwallis’ best features.
Effects of Eco-Friendly Ultrasonic Treatment
After the treatment, algae levels have significantly reduced as water clarity increases, encouraging plant growth and therefore, and further increasing oxygen levels. Our ultrasonic treatment reduces algae blooms by up to 90%, compared to no treatment previously. The LG Sonic’s ultrasonic technology has evidently worked, showcasing the potential to restore entire ecosystems.
Advantages of the LG Sonic E-LINE:
- Eliminate up to 90% of existing algae
- Prevent the growth of new algae
- Up to 200m/ 650ft treatment range per unit
- Safe for fish, plants and other aquatic life
How does ultrasound work to remove algae effectively?
- Algae moves to the water surface for photosynthesis. The ultrasound creates a sound layer at the top of a water body.
- The ultrasound affects algae’s vertical movement by fixing them in the water column.
- Without sunlight and nutrients, the algae sink to the bottom, where they decompose without releasing toxins.
- In time, bacteria will degrade the algae.
