WATER SPECIALISTS FOR THE MUNICIPAL WATER TREATMENT SECTOR

Almost always, the Municipal water treatment sector’s treatment of water is subject to exacting standards and regulations. Flootech can be relied upon to recommend the ideal processes, technologies and products for our clients to address their particular circumstances and meet their specific requirements.

As regulatory requirements have proliferated, Flootech has become a leader in the development of equipment and technologies to meet the new demands.

Clarifiers and Multimedia Sandfiltration

Our Clarifier units are designed to provide the most economic solution for precipitation and clarification. The basic Clarifier design provides for coagulation, flocculation, solids recirculation, clarification and positive sludge removal in a single basin, eliminating the need for multiple tanks and associated piping. Flootech’s range of clarifier units, refined by years of application experience in the engineering and manufacturing industries, assure that a best fit solution can be found for any unique plant requirements.

Flootech’s clarification process softens water, removes turbidity, algae, color, iron and metals. Ideal for removing suspended solids from raw water, if clarified water requires further polishing by filtering, residual solids are efficiently removed via granular media filtration systems, which use sand and anthracite. Solid particles are trapped in the media and, when exhausted, are flushed by backwashing with air and water.

Dissolved Air Flotation

Residual oil and suspended solids are separated by dissolved air flotation (DAF) called FlooDaf® microflotation. During this process pressurized air is dissolved into recycled effluent water to generate micro bubbles. The pressure is then released into the feed flow. The bubbles produce agglomerates with smaller specific gravity than that of water by attaching themselves with suspended particles. These agglomerates rise through the liquid and the air-water-solid mixture is distributed uniformly across the flotation tank, thus forming a floating sludge layer that is removed by surface skimmers. Heavier solids settle to the bottom of the tank and can be discharged from there. Clear liquid supernatant on the sediment layer is withdrawn under a tank baffle and over the weir for reuse or for treatment by coagulation and flocculation.

For coagulation and improved flocculation, chemical treatments are usually needed to maximize the efficiency of floc formation and separation. Emulsions of oily materials can be broken by acidification, the addition of alum or iron salts (inorganic coagulants) and by using emulsion-breaking polymers.

Flootech offers circular and rectangular FlooDaf® microflotation units of several sizes and varieties to suit the particular needs of individual sites and to optimize the process.

flootech raw water treatment solution Flootech’s clarification process softens water, removes turbidity, algae, color, iron and metals. Ideal for removing suspended solids from raw water, if clarified water requires further polishing by filtering, residual solids are efficiently removed via granular media filtration systems, which use sand, anthracite and/or activated carbon. Solid particles are trapped in the media and, when exhausted, are flushed by backwashing with air and water.
flootech sludge handling solution When wastewater is treated either biologically or through physical/chemical methods, sludge is produced. The disposal method for the sludge and the associated costs can significantly affect the payback and economics of a wastewater treatment plant installation. Flootech has experience treating sludges from all types of municipal and industrial wastewater systems and is able to offer solids handling equipment for sludge thickening or dewatering.
flootech chemical handling solution Correct chemical storage and dosing is essential to the proper operation of industrial and municipal water and wastewater treatment plants. The correct selection of chemicals, chemical dose rate and mixing parameters is critical and has a direct impact on the availability, performance and service life of process equipment.
flootech parts and services solution Flootech is proud to supply complete processes and to provide the diverse knowledge and expertise required to ensure that the plant and processes operate reliably. We target at optimized process results and economical operational costs at the customer’s plant. Customer satisfaction is our first priority. A delivery from Flootech ensures close cooperation with the customer starting from the evaluation of the best technological solution to installation, process optimization, training and start-up as well as after sales services covering spare part support and maintenance.

flootech floodaf technology Dissolved Air Flotation (also known as microflotation) is a well-known method of particle separation. Microbubbles are created by dissolving air into water under pressure. When the air-saturated pressurized water is released, microbubbles are formed. Chemical, physical and electrical forces cause suspended solids and colloids to attach to one another and to air bubbles. These particle flocs then float to the water’s surface and are scraped off. Coagulation and / or flocculation chemicals are used to enhance the process.
