CLARIFLOCCULATOR PROCESS PDF

Term definition[ edit ] According to the IUPAC definition, flocculation is "a process of contact and adhesion whereby the particles of a dispersion form larger-size clusters". Meanwhile, flocculation is a mixing technique that promotes agglomeration and assists in the settling of particles. Flocculation is affected by several parameters, including mixing speeds, mixing intensity, and mixing time. The product of the mixing intensity and mixing time is used to describe flocculation processes. Surface chemistry[ edit ] In colloid chemistry , flocculation refers to the process by which fine particulates are caused to clump together into a floc.

Term definition[ edit ] According to the IUPAC definition, flocculation is "a process of contact and adhesion whereby the particles of a dispersion form larger-size clusters". Meanwhile, flocculation is a mixing technique that promotes agglomeration and assists in the settling of particles.

Flocculation is affected by several parameters, including mixing speeds, mixing intensity, and mixing time. The product of the mixing intensity and mixing time is used to describe flocculation processes.

Surface chemistry[ edit ] In colloid chemistry , flocculation refers to the process by which fine particulates are caused to clump together into a floc.

The floc may then float to the top of the liquid creaming , settle to the bottom of the liquid sedimentation , or be readily filtered from the liquid. Flocculation behavior of soil colloids is closely related to freshwater quality. High dispersibility of soil colloids not only directly causes turbidity of the surrounding water but it also induces eutrophication due to the adsorption of nutritional substances in rivers and lakes and even boats under the sea.

Physical chemistry[ edit ] For emulsions , flocculation describes clustering of individual dispersed droplets together, whereby the individual droplets do not lose their identity.

Flocculation is used in mineral dressing [6] , but can be also used in the design of physical properties of food and pharmaceutical products. In dispersed clay slurries , flocculation occurs after mechanical agitation ceases and the dispersed clay platelets spontaneously form flocs because of attractions between negative face charges and positive edge charges. Biology[ edit ] Flocculation is used in biotechnology applications in conjunction with microfiltration to improve the efficiency of biological feeds.

The addition of synthetic flocculants to the bioreactor can increase the average particle size making microfiltration more efficient. When flocculants are not added, cakes form and accumulate causing low cell viability. Positively charged flocculants work better than negatively charged ones since the cells are generally negatively charged. Three different coagulants are mainly used: [11].

Sewage Treatment Plants

Posted by Water Treatment in Sewage Treatment 20 responses Clariflocculator in Waste Water Treatments In large waste water treatment plants, the flocculator and the clarifier are combined together to achieve economy in construction. The combined unit of flocculator and clarifier is known as clariflocculator in waste water treatment process. Clariflocculator shall have two concentric tanks with inner tank serving as flocculation basin and outer tank serving as clarifier. Plate and Tube Settlers are shallow settling devices consisting of stacked offset trays or bundles of small plastic tubes of various geometries. They are used to enhance the settling characteristics of sedimentation basins.

CLARIFLOCCULATOR PROCESS PDF

Kagazahn The effluent is further treated to remove nitrogen, phosphorus, microbes and fine suspended particles Technical specifications Equalisation Tank Balancing Tank Retention time: Our range of water pollution control systems includes: The sludge formed from the settled particles at the bottom of each clarifier, if left for an extended period of time, may become gluey and viscous, causing difficulties in its removal. When implemented and operated properly, they can afford cost-savings in profess investments, lower footprint, and cost-savings in processes. Product Procss Clariflocculators are combination of both flocculation as well as clarification. The fine particles then build up into a larger mass prodess then slides down the tube channels. As per Client requirement Drives for Flocculator are selected according to the application and the required torque, to achieve the tip speed of the flocculation paddle up to 0. In this process, dissolved oxygen demanding organic substances are removed The waters is then clarified by separating treated liquid from grown bacterial cells using gravity Tertiary Treatment: Peripheral drive is designed with M.
