Capable of removing turbidity, color, TOC and other constituents in both municipal and industrial water applications, the Superpulsator® treats billions of gallons of water per day in hundreds of installations throughout the world. Performance Advantages Clarified turbidity of < 1-2 NTU Ability to handle high raw solids (0 to 2000+ NTU)
How does a Pulsator clarifier work?
The Pulsator® is a pulsed sludge blanket clarifier. The sludge formed during flocculation is made up of an expansion mass. Water, that has coagulated beforehand, arrives from the bottom of the device and flows through this sludge blanket to emerge clarified at the top of the settling tank.
What is sludge blanket clarifier?
Abstract: A sludge blanket clarifier is a treatment unit combining flocculation and upward flow sedimentation, which is more efficient compared to the conventional sedimentation tank. It has the ability to treat water at a faster rate, resulting in less space requirement.
What is a solids contact clarifier?
Solids contact clarifiers combine the process of mixing, flocculation and sedimentation in a single tank. Recirculation of solids and mixing is accomplished by a radial or axial turbine. Flocculation occurs within the reaction well. Sedimentation occurs in the clarification zone.
How is clarified water treated?
Water clarification helps remove suspended solids and particulate matter – usually with the help of flocculants and coagulants, which improve settling. New-Lamella plates can be used to improve the suspended solids removal and reduce the footprint of the unit.

How is sludge blanket formed?
As the flow progresses up through the unit, the rise rate becomes less than the settling velocity of the precipitation solids. This process allows a sludge blanket to form and act as a filter and catalyst providing intimate contact between raw water, treatment chemicals and previously formed precipitates.

What is the purpose of a clarifier?
A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and (or) thickening. Concentrated impurities, discharged from the bottom of the tank are known as sludge, while the particles that float to the surface of the liquid are called scum.
What kind of polymer is used in water treatment?
Cationic polymersCationic polymers are used in dredging, municipal wastewater treatment plants, food processing, agricultural and dairy applications.
Is clarified water safe for drinking?
Answer: clarified water is water which is pure and clarified, it is fit for drinking and human consumption also and we can also use it for daily needs.
How is clarified water different from clean water?
Water is then allowed to settle in a tank where solids like faeces (called sludge) settle at the bottom and are removed with a scraper. A skimmer removes the floatable solids like oil and grease. Water so cleared is called clarified water. ... The treated water has low level of organic material and suspended matter.
What does clarifying water mean?
Clarification is an essential step in a water or wastewater treatment process to remove suspended solids through gravity settling, providing a clarified liquid effluent.
