Advanced Gravity Separation
For years, a key part of the Biolac System has been the simple, common wall secondary clarifier that completes the system. Efficient liquid-solids separation is critical to maintaining high quality effluent and the Biolac® clarifier has proven to perform with excellent reliability. Many plants produce effluent TSS between 5 and 10 mg/l. Along with hundreds of successful installation over the past 25 years comes the experience and learning that leads to new innovation and development.
The EZClear™ design builds on the successful innovation of the existing Biolac® clarifier while maintaining all the features and benefits that owners want.
– Low effluent TSS
– Rapid sludge removal
– Simple maintenance of all equipment from the surface
– Gravity RAS flow option
– Low hydraulic profile
With lengths up to 100 feet, the EZClear™ almost doubles the available surface area per clarifier, expanding the range of application and further reducing operation and maintenance requirements while improving effluent quality.
Biolac® EZClear™ Clarifier
| Features | Benefits |
|---|---|
| Effluent TSS guaranteed – as low as 10 mg/l TSS | Provides the owner with the confidence and security of a successful EZClear™ installation |
| Turned 90° from the original Biolac™ clarifier, the EZClear™ Clarifier is available in lengths up to 100 feet. | The surface area available per clarifier is increased by over 80%, providing higher flow capacity for lower total cos |
| Vertical, common wall construction with the Biolac™ treatment basin and other structures | Reduces the amount of concrete and excavation required, lowering the cost of construction. Clarifier/RAS footprint is at least 30% less than with separate circular clarifiers |
| Low-velocity, equally distributed crossflow design | Inlet distribution pipes ensure superior hydraulic efficiency and eliminates the density currents that destroy clarifier performance |
| EZClear™ feed channel orifices control the flow into the clarifier | Controlled equalization can automatically be provided in the Biolac® treatment basin, dampening short term peak clarifier loading, improving performance |
| Feed channel slide gate | Provides easy isolation of each EZClear™ from the Biolac® treatment basin |
| Rapid sludge removal from the entire EZClear™ V-bottom | Keeps sludge healthy and in the process treating wastewater – no danger of denitrification or P re-release in the sludge collection zone |
| Automated sludge wasting | Improves process stability and performance while reducing operator time and attention |
| Surface wasting slide gate | Allows for removal of poor settling floc/scum from the clarifier feed. The operator decides when and how much to waste this way |
| Automated scum skimming and removal | Minimizes scum flow while reducing operator time and attention |
| Both airlift pumps with gravity RAS flow, and mechanical pumps with pumped RAS flow are available | Design flexibility depending on plant hydraulics and operator preference |
