Solids CONTACT CLARIFIER - WesTech Engineering, Inc.

Solids CONTACT CLARIFIER™ Overview: The WesTech Solids CONTACT CLARIFIER™ has the ability to act as both an enhanced flocculation device as well as a high rate chemical precipitator. Mixing, internal solids recirculation, gentle flocculation and gravity sedimentation are all combined into a single unit.

Water Handbook - Clarification | SUEZ

These clarifiers are termed "upflow" because the water flows up toward the effluent launders as the suspended solids settle. They are characterized by increased solids contact through internal sludge recirculation. This is a key feature in maintaining a high-clarity effluent and a major difference from horizontal clarifiers.

Solids Contact Clarifier – Rock Water Equipment

Solids Contact Clarifiers RockWater's solid contact clarifiers are designed and proven for highly efficient flocculation, sedimentation, and clarification in a single compact basin. Solids contact units are widely used for the removal of turbidity for lime softening, and for chemical coagulation in municipal and industrial applications.

water treatment – sludge contact clarification - Degremont®

This type of clarification simultaneously applies the principles of solids contact flocculation (see flocculation with sludge contact) in combination with the hindered settling of flocculated particles (see different types of sedimentation). The water to be treated, having previously been coagulated, is put into contact with the pre-existing sludge: there is a far greater possibility that the colloids in the water will …

CONTRAFLO Solids Contact Clarifier

CONTRAFLO success of solids contact clarification results from bringing raw water and treatment chemicals into intimate contact with previously formed precipitates. These precipitates help accelerate the chemical reaction and serve as a deposit point for newly-formed precipitates which helps to maximize the treatment chemical efficiency and create large heavy sludge particles that settle rapidly.

Separation: Be Clear About Clarifiers | Chemical Processing

2017/06/28 · Clarifiers usually incorporate mechanical solids-removal devices that move as slowly as practical to minimize re-suspension of settled solids. Clarified liquid often is pumped to filters to eliminate any residual particles; filtered liquid then flows to the next process. Tanks are sized to give liquid an optimal residence time.

SMITH & LOVELESS INC.

operations, or where a chemical reaction is taking place, is usually best achieved in one operation by the use of a solids contact clarifier such as the Smith & Loveless CLAR-I-VATOR ®. From a design point of view, it’s desirable to create an environment where the settling time is minimized by shortening the settling distance yet minimizing turbulence

A CLAR-I-VATOR solids contact clarifier overcomes some of the problems exhibited in the sludge blanket clarifier. It basically controls the chemical reactions taking place, flocculation, and the sedimentation phenomena more positively than in a sludge blanket clarifier and is not as readily affected by changes and flows or by process. In the CLAR-I-VATOR solids contact clarifier, the liquid stream enters into a …

Clarifiers - SCT

Clarifiers, through gravity sedimentation of a dilute suspension, are used to produce a relatively clear overflow stream. This is in contrast to thickeners which are used to increase the percent solids of the underflow. Clarifiers are a critical part of many industrial water and wastewater treatment systems.

Memclean MS Medium - Evoqua

The lamella style clarifier includes an air operated diaphragm pump to periodically remove settled solids from the bottom of the clarifier. For units that are rated for 300 gallons per minute or more, the rapid mix and flocculation tanks are optional. Polymer from an optional chemical make-up tank is added to the wastewater in the rapid mix ...

2-1 Recausticizing - Principles and Practice

The primary chemical reaction in the lime slaker is the hydrolysis of quick lime. This reaction is exothermic. CaO + H2O = Ca(OH)2 + Heat The reaction proceeds very fast and generates a lot of heat. Calcium hydroxide reacts instantaneously with the sodium carbonate in the green liquor to form sodium hydroxide and calcium carbonate.

ClariMax™ Series Inclined Plate Clarifier

One of the greatest issues faced by traditional counter-current clarifiers is the impact that accumulated solids have on overall clarifier efficiency. As the solids accumulate on the surfaces of the plates, they have to migrate along the surfaces of the plate to the bottom of the plate where they are discharged into the sludge collection chamber.
