High Rate Solid Contact Clarifier

These types of clarifiers are typically designed to handle a high flow rate of water with variable flow in a confined space. These types design features to enhance the settling of suspended particles, ensuring a more rapid and efficient separation process.

Clarifier

Clarifier is a key component in water treatment plants designed to remove suspended solids and other impurities from water. Its primary function is to separate solid particles from water by allowing them to settle to the bottom. This process helps clarify the water, making it suitable for further treatment or direct distribution. Clarifiers come in various designs, including circular and rectangular shapes. The choice of design depends on factors such as the characteristics of the raw water, the required treatment capacity, and available space. Additionally, some clarifiers may use inclined plates or tube settlers to enhance the settling process by providing more surface area for particles to settle.

Lamella Clarifier

A Lamella Clarifier, also known as an inclined plate settler or parallel plate clarifier, is a water treatment device used for the separation and removal of suspended solids from water. It operates on the principle of gravity settling, where the gravitational force causes the particles to settle down. The Lamella Clarifier consists of a series of inclined plates or lamellae, which are closely spaced parallel plates inclined at an angle between 45 to 60 degrees. These plates provide a large surface area for the suspended particles to settle. The inclined arrangement allows for a longer settling path, increasing the efficiency of particle removal.

Clari-flocculator

Clariflocculator is a combination of flocculator and clarifier in which floc formation and its subsequent removal by sedimentation occur. It has two concentric tanks where the inner tank serves as a flocculation basin and the outer tank serves as a clarifier.

Grit Separator/ Detritor

The detritor functions as a continuous flow tank where sedimentation occurs as a result of gravity, causing the grit to settle, while the excess water flows out through outlet weirs located on the opposite side. A scraper mechanism is employed to remove the settled grit, directing it towards openings at the bottom of the sidewall. The collection chamber operates on the principle of velocity, skillfully designed to allow only grit to settle, allowing organic matter to overflow. The classifier mechanism involves a reciprocating rake, powered by a motorized gearbox. The gathered grit undergoes a thorough washing process and is then discharged from the top of the reciprocating/screw classifier through a chute for proper disposal. The washed organic liquor present in the classifier is returned to the detritor collection chamber through the organic return pump.
