2. How does the MBBR suspended media achieve a service life exceeding 15 years?

Our MBBR media is manufactured using brand-new HDPE raw materials sourced from major Sinopec plants. The durability is enhanced through a specific material formulation that includes an optimized UV-resistant formula and hydrophilic properties, which maintain structural integrity and biological activity over a projected service life of more than 15 years.

3. Why is the swirl aerator recommended for treating high-concentration wastewater rather than traditional aeration heads?

The Xi-city swirl aerator is specifically designed to address common industrial challenges such as high-concentration wastewater, sludge accumulation and blockages.

Key design features:

• Clog-resistant and maintenance-free: With no moving parts subject to wear, no regular mechanical maintenance is required, and the service life exceeds 10 years.
• Uninterrupted operation: Installation requires no draining of tanks or production stoppages and can be carried out whilst the water is flowing.
• High durability: High oxygen utilisation and low pressure drop significantly reduce overall energy consumption. Even under harsh conditions, it offers a reliable service life of 10 to 20 years.

4. What are the key installation requirements to ensure aerator efficiency?

To maintain optimal oxygen transfer and prevent system failure, the following must be observed during installation:

• Levelness: The deviation of the air supply branch pipe must not exceed ±10 mm.
• Cleanliness: Pipes must be thoroughly purged of debris before installation to prevent internal obstructions.
• Tightness: All underwater joints must be verified as leak-free.
• Environmental conditions: For systems requiring bonding, work is strictly prohibited during rain or in high-humidity conditions.
