Restoring water quality at a public park lake in China
Sludge accumulation, algae growth and poor water clarity were impacting one of the park's most valuable attractions.
Key Facts
- Project:
- Yanshan Garden Public Park
- Location:
- Taicang, Suzhou, China
- Type and size:
- Freshwater, 6.18 acres
- Problem:
- Sludge accumulation, algae blooms and foul odors
- Product Applied:
- SchlixX
- Results:
- Improved water clarity, reduced sludge accumulation, suppression of algae growth and a significant reduction in foul odours
The Challenge
Located at the heart of Yanshan Garden Public Park in Taicang, China, the lake serves as a focal point for visitors and residents alike.
However, years of nutrient loading, fish activity and organic matter accumulation had led to declining water quality, significant sludge build-up and recurring algae growth.
The resulting cloudy water and unpleasant odours detracted from the visitor experience and made it increasingly difficult for operators to meet local water quality standards.
A cost-effective solution was needed that could improve conditions while minimising disruption to the park and its visitors.
The Solution
Following water quality analysis, SchlixX was selected to address the underlying causes of poor water quality.
The treatment programme focused on reducing nutrient availability, increasing oxygen levels and supporting the natural biological processes responsible for breaking down accumulated organic sediment.
To allow for targeted management, the lake was divided into five sections.
Following initial site challenges caused by simultaneous shoreline restoration works, treatment efforts were concentrated within a contained section of the lake where conditions could be more effectively controlled and monitored.
The Results
Just one month after treatment began, visible improvements were already apparent within the treated section of the lake.
Water clarity improved significantly, allowing fish and lakebed features to become visible from the surface. At the same time, sludge accumulation was reduced, algae growth was brought under control and foul odours diminished.
The contrast between treated and untreated sections of the lake provided a clear demonstration of the impact of the restoration programme, ultimately supporting plans to expand treatment across the remaining areas of the waterbody.
Key Outcomes
Significant improvement in water clarity
Visible reduction in sludge accumulation
Reduced algae growth
Reduced foul odours
Improved visitor experience
Support for long-term lake restoration objectives
Why It Matters
Public lakes are often among the most visible assets within parks and recreational spaces.
Maintaining water quality is essential not only for ecological health, but also for public perception and visitor enjoyment.
The Yanshan Garden project demonstrates how addressing nutrient loading and sediment accumulation at the source can restore water quality and improve the long-term health of highly visible public water bodies.
