Wastewater Treatment Plant Commissioning Checklist

What really keeps an MBBR system running? It's not just the plastic media, but also the tiny microbes living on it. They're the real workers cleaning up the water.

Here's what makes them active:

Oxygen: helps them breathe and break down waste faster. Wastewater makeup: gives them food and nutrients to grow.

Media pore size: too big, they slip away; too small, water can't move well.

Temperature & pH: need the right balance to stay healthy.

Aeration & flow time: keep the media moving and in contact with water.

When everything's just right, the biofilm turns into a strong, self-renewing ecosystem, tiny microbes working nonstop to clean water naturally.

Drum Pond Filters remove suspended solids, leftover feed, and fish waste quickly and efficiently. The rotating drum captures fine particles, while the automatic backwash system cleans the screen without downtime. Compact, energy-efficient, and easy to maintain, it’s suitable for aquariums, landscape ponds, and RAS systems, keeping your water healthy.

As experts in water treatment, AquaSust also supply other components for RAS systems, including:

Rotary Drum Filter

Protein Skimmer

Ozone Generator

PP Aquaculture Vertical Flow Settler

PP Fish Pond

1️⃣ Stronger & More Durable Made with reinforced ABS housing and premium formula EPDM, built to withstand years of use.

2️⃣ Premium German Materials We use UV-protected EPDM imported from Lanxess, Germany, with lower plasticizer content for better performance.

3️⃣ Efficient Airflow, Longer Life Membrane wall thickness of 1.8–2.0 mm strikes the perfect balance for low pressure loss and extended service life.

4️⃣ Consistent Quality Every diffuser is produced under strict QC standards, ensuring stable aeration performance and easy tank maintenance.

5️⃣ Double Check Valve Prevents backflow, keeping your system clean and efficient.

6️⃣ Non-Tearing, Non-Clogging Design Special slit structure resists damage and blockage, even in challenging wastewater conditions.
