How does a lamella clarifier work

This explains the clarifier's unique working principle and what makes it effective. Tube settlers are kind of devices that utilize a bunch of small-bore tubes that are installed in an inclined at an angle of 60 degrees to help in sedimentation.

The tubes come in different shapes which may be rectangular or circular. Water rises through the tubes and allows particulates to fall on the surface tube which enables the sludge to gain weight so it can move down the tunes and settle on the bottom of the basin.

This way, the sludge can be removed through conventional sludge removal means. What makes tube settler media favorable? For starters, they provide an inexpensive way of upgrading your water treatment plant clarifier and the sedimentation basins, thus improving their performance. They help in reducing the footprint needed in new installations by minimizing the solids loading on the downstream filters. The tube settlers are made of lightweight PVC, which ensures that it can be supported with minimal structures.

Clarifiers are used where the water that needs treatment has a high concentration of suspended solids. They are used where water treatment seems hard due to a high lamella clarifier sludge levels which need to be removed before the polishing process. They work on the principle of gravity settling which make them the most ideal choice. They allow the heavy suspended solids to settle in the clarifier and the water flows out clear and ready to be polished for reusing.

The natural settling can be enhanced by adding coagulant and polyelectrolyte. The coagulant is meant to neutralize charges and agglomerate the solids to form micro-floc. Polyelectrolyte, on the other hand, brings the flocs together and binds them to form long chains making them heavy so they can easily settle down. Mostly, the wastewater will contain scum material which will not settle down and therefore needs to be collected on the clarifier's surface. In this case, a scum removal arrangement is provided.

It is recommendable that you remove any oils and grease before realizing wastewater to the clarifier. It has an outlet skimmer that holds captive free oils and grease, but this is only safe when it is in a small amount. The main applications of clarifiers are;. The primary purpose of a clarifier in wastewater treatment is the removal of solids or particulates. It ensures that elements that cannot be eliminated through other processes such as distillation are removed before the water heads to city sewage or inspection tank, where it is collected for further treatment and purification.

The best part about clarifiers is that they have minimal moving parts which make maintenance easy and manageable. See our article: Polymers and their use in Wastewater Treatment.

The lamella clarifier process makes this kind of clarifier ideal for certain applications where space is limited or settling needs to occur indoors In the pictures associated with this article, you can see a lamella clarifier in a plant where we are doing a complete managed wastewater program.

It is generally recommended that you remove excess oils or grease before filtering the wastewater into the lamella clarifier. While there is an outlet skimmer for catching these oils, it is recommended only in smaller amounts.

In wastewater treatment, the job of the clarifier is to remove solids. One benefit of lamella clarifiers in waste treatment facilities is that they require minimal upkeep and are easy to maintain due to their lower amount of moving parts. The easiest way to clean these clarifiers is by draining it and removing any excess buildup on the plates and cones.
