Trusted BioMedia Starts with Virgin HDPE – Here’s Why
In biological wastewater treatment systems such as MBBR and IFAS, the choice of media material directly influences the efficiency, longevity, and safety of the entire process. At BIMEX, we manufacture our BioMedia 800 and 850 exclusively using virgin HDPE (high-density polyethylene) — a material that meets the highest performance and environmental standards for long-term operation in industrial and municipal wastewater treatment plants (WWTPs).
The Material Matters: Why Virgin HDPE?
Virgin HDPE is a non-toxic, UV-stabilized, and chemically resistant thermoplastic that ensures dimensional stability, minimal degradation, and superior structural integrity — all of which are critical in demanding water treatment environments.
| Property | Virgin HDPE Advantage |
|---|---|
| Chemical Resistance | Excellent against acids, alkalis, hydrocarbons |
| UV Resistance | Stabilized for outdoor exposure, prevents embrittlement |
| Service Temperature | Performs between 0–80 °C without deformation |
| Specific Gravity | ~0.94 – 0.97 (allows uniform suspension in aeration tanks) |
| Longevity | Service life exceeds 20 years |
| Ecological Impact | Non-toxic, recyclable, and safe for aquatic environments |
Performance Under Pressure
Unlike recycled plastics, virgin HDPE resists microbial degradation, swelling, or cracking, even in high-load industrial applications. BIMEX biomedia is tested according to ISO 1183-1:2019 and BS ISO 20457:2018, ensuring performance under high flow, aeration, and fluctuating pH levels. This makes it ideal for:
-
Municipal wastewater plants
-
Food, chemical, and textile industries
-
Decentralized or containerized treatment units
BIMEX Material Sourcing and Certification
We source only premium virgin HDPE from:
-
SIDPEC (Egypt)
-
SABIC (Saudi Arabia)
Both suppliers are globally recognized for polymer purity and consistency. Our manufacturing processes are also certified under:
-
ISO 9001 (Quality Management)
-
ISO 14001 (Environmental Management)
-
ISO 45001 (Occupational Health & Safety)
-
ISO 50001 (Energy Management)
Environmental and Safety Benefits
Virgin HDPE not only improves performance—it also aligns with modern environmental priorities:
-
♻️ Harmless to ecosystems when disposed of correctly
-
🌱 Lightweight and non-hazardous, reducing transport and handling risk
-
🚫 No toxic leachates, making it safe for effluent and reuse systems
Why BIMEX Uses Virgin HDPE in BioMedia 800 & 850
Both BioMedia 800 and BioMedia 850 are engineered for optimized void ratio, surface area, and hydraulic performance—all of which are maximized by the strength and purity of virgin HDPE. The result is:
-
Higher BOD₅ and ammonia removal
-
Less clogging and longer life
-
Lower operational cost over time
When reliability, safety, and performance matter, virgin HDPE offers clear advantages over alternative materials. By using virgin HDPE from certified sources, BIMEX delivers BioMedia that meets the toughest demands of wastewater treatment while remaining safe, sustainable, and cost-effective.
