Florrea MaxAntiscal^? series antiscalants and dispersants
Formation of mineral scales is a common problem in industrial processes, desalination as well as sewage and waste water treatment facilities.

Antiscalants are substances preventing crystallized mineral salts (scale) from forming in e.g. water pipes, anaerobic digesters and dewatering trains.

Our broad range of polymeric antiscalants and dispersants prevent inorganic scale and crystalization and help reduce maintenance time.

The Florrea MaxAntiscal^? product family is a versatile series of polymeric antiscalant and dispersant chemistries designed to handle the most vexing scale control challenges.

Applications for antiscalants
    ●Once-through and recirculating cooling water systems
    ●Boiler water treatment and sludge dispersion
    ●Municipal wastewater treatment
    ●Beet and cane sugar processing
    ●Industrial water treatment
    ●Detergents and cleaner formulations
    ●Municipal wastewater treatment

In mineral processing operations, insoluble salts—typically calcium carbonate, calcium sulfate, magnesium and silicate—drop out of process water and solutions. This causes scale to form on processing equipment, which can restrict pipe volume. This in turn reduces flow and ultimately requires downtime for cleaning.，
Florrea Maxantiscal^? series antiscalants use multiple scale control mechanisms to reduce the potential for scale formation. These polymer chemistries control scale in many mineral processing applications, from process water to Merrill Crowe circuits

Florrea MaxAntiscal series antiscalants
are proven to deliver a number of benefits:
    ●Improve throughput and productivity
    ●Minimize cleaning costs
    ●Reduce downtime
    ●Reduce fresh water usage
    ●Improve capital asset life

Mode of Action of MaxAntiscal
Florrea Maxantiscal antiscalants bring together multiple scale control mechanisms to significantly reduce the potential for scale.

    ●To prevent initial scale formation, the antiscalants nucleate small, scale-forming crystals in the solution so that the crystals do not attach to and form scale on equipment surfaces (dispersion and sequestration).

    ●To slow and minimize scale formation, the antiscalants modify the surfaces of existing crystals so that new layers of scale do not form (threshold inhibition).

    ●For any scale that does form, the antiscalants disrupt the structure of the scale (crystal modification), making it softer and easier to remove.

Antiscalants were evaluated for control of calcium carbonate (CaCO3) in gold processing applications.
Under severely supersaturated conditions, 100 percent inhibition was achieved with 30 ppm antiscalant. Laboratory and field testing established that an antiscalant could both inhibit scale buildup and remove an estimated 0.5 kg/m2 per annum of pre-existing scale. A program was developed to control CaCO3 at a gold mill experiencing severe scale buildup. Annual accumulation of as much as 3 cm of scale in process piping was reduced to unmeasureable levels when 10 ppm antiscalant was applied.

No scale-related upsets in mill operation occurred during a five-month trial period.
Introduction Inorganic mineral scale is a crystalline deposit that forms when dissolved mineral constituents exceed the solubility of the respective mineral phase. Formation of mineral scale adversely affects a wide range of industries and is of particular interest in mining and metals processing.

Scale affects numerous stages of metal extraction processes. Restricted flow in piping, nozzles, valves, screens, pumps and other components used to transport mineral slurries, metal concentrates, and tailings as well as scale in millwater and thickener overflow circuits are primary concerns .

Heap leaching, comminuation, flotation, vat leaching, carbon adsorption, and heat exchangers as well as oxidation steps used in processing sulfidic ores are among key unit operations that may be adversely affected .

Antiscalant chemicals are designed to prevent formation and growth of mineral scales such as CaCO3.

These chemicals, which include two primary classes – phosphonates and anionic carboxylate polymers and copolymers - are added to the gold processing stream at low parts-per-million (ppm) concentrations to interfere with nucleation and growth of scale forming crystals and to disperse fine particulate material.
Application points may be located throughout the gold extraction process. Evaluation of the performance of antiscalants plays a critical role in determining the best product for a specific application.
Performance evaluations include laboratory testing, pilot scale studies, in-plant trials, and ongoing performance monitoring during mill operation.
