WATER CLARIFICATION SYSTEMS
The clarification process is important in water or wastewater treatment, as it involves the removal of suspended solids, resulting in a clarified process stream.
In water treatment, the process of clarification is often accelerated through the applications of coagulants and flocculants, in order to enhance gravity settling.READ MORE
The process of removing suspended solids, in order to produce a clarified process stream is important to ensure water treatment and wastewater discharge requirements are met. There are a variety of different clarification systems available in a range of different configurations and sizes that can be tailored to meet individual project needs.
Before raw water or wastewater enters a clarifier, coagulants and flocculants are usually applied, in order to instigate the finely suspended particles to clump together and form larger and denser particles, called flocs, that settle relatively quickly, compared to untreated feedwater. The upstream chemical pre-treatment process is desirable as it allows the separation of the solids in the clarifier to occur more efficiently. The clarifier works by permitting the heavier and larger particles to settle to the bottom of the clarifier. The particles then form a layer of sludge at the base of the clarifier requiring regular removal and disposal. The clarification process is commonly used at the early stages of water treatment as it reduces the solids loading and minimises downstream water treatment processes like filtration.
Tubes or Lamella plates are commonly used in rectangular clarifiers to increase the settling capacity by reducing the vertical distance a suspended particle must travel. High efficiency settlers use a stack of parallel tubes, rectangles or flat pieces separated by several centimetres and sloping upwards in the direction of flow.
These structures work providing a very large surface area onto which particles fall and become stabilized, aggregating very fine particles that can settle as the flow exits the plates. Structures inclined between 45° and 60° allow gravity drainage of accumulated solids. Tube settlers may allow the use of a smaller clarifier and may enable finer particles to be separated with residence times of usually less than 10 minutes.
