Antiscalants and Dispersants for Water Treatment

Q: Mining and slurry treatment

When mining , the extraction of calcium, phosphate, kaolin, and sand often requires the minerals to be mixed with water to form a slurry. A slurry is a mixture of a solid and liquid which has a natural tendency to separate. If separation does occur several transportation, storage, and manufacturing problems can arise, including difficulty pumping or problems with production. Brennsperse Dispersants help with the free flow of slurries by dispersing the slurry solids to slow or prevent separation. As a result, this yields a more consistent slurry.

Control scale and deposits with Brennsperse™ polymers and organic phosphonates

The Brennsperse Dispersants and Antiscalants product line delivers effective and economical treatment options for several markets:

Boiler water treatment
Cooling water treatment
Detergents and cleaners
Oil and gas
Reverse osmosis
Slurry and mining
Wastewater treatment (Struvite Control)

Products from the Brennsperse portfolio help control calcium carbonate, calcium phosphate, calcium sulfate, and many other scales and deposits. High market demands for reusing water, water conservation, and the need to use water of lesser quality, all result in scale becoming more prevalent.

Major product categories include: Homopolymers, Copolymers, and Terpolymers

Uses and applications for dispersants and antiscalants

Many Brennsperse Dispersants and Antiscalants are available in various chemistries, molecular weights, percent actives, and pH ranges. Some products carry certain FDA 21CFR clearances, Kosher certifications for food, and NSF/ANSI 60 certifications for drinking water.

These products are commonly used to help control calcium carbonate, calcium phosphate, calcium sulfate, and many other scales and deposits. As increasing demand for water conservation and reuse, and the need to use water of lesser quality, scales of silica, barium, strontium, and struvite are beginning to appear in cooling water and reverse osmosis. Scale is even appearing in wastewater applications.

What is scale?

A scale is soluble material in water which precipitates, becomes insoluble, and deposits on a surface. Various factors like temperature, pH, alkalinity, over saturation, or a change in water chemistry can affect the development of scale. Cooling water treatment scale can inhibit heat transfer and restrict water flow. Scale within a boiler will reduce heat transfer which reduces the boiler’s efficiency. In reverse osmosis, scale can restrict the flow and foul the membrane.

Dispersants and antiscalants for various markets

Keep scrolling to find out how dispersants and antiscalants are used in water teatment, detergents and cleaners, and mining and slurry treatment.

The presence of scale and deposits on cooling water exchangers and boiler tubes reduces heat transfer and increases energy consumption. When scale or deposits occur on reverse osmosis membranes, they hinder membrane permeation which increases energy consumption and reduces production. Struvite in wastewater treatment plants restricts water flow and results in the need for periodic cleanings.

Brennsperse Dispersants and Antiscalants are used in cooling treatment, boiler water treatment, reverse osmosis, and wastewater treatment to prevent scale formation by one or a combination of the following methods:

“Threshold Effect” scale inhibition: the ability of very small amounts of scale inhibitors to
keep large quantities of scalants in solution
Crystal Modification: Dispersants disrupt, alter, or weaken the formation of a crystal structure.

Sequestration: the ability to inactivate a metal ion and keep it in solution,
preventing its negative side-effects
Dispersion: prevents the agglomeration of scale particles
Corrosion Control: provides synergistic corrosion control when used with zinc,
phosphates, nitrates, molybdates, and others

The need to prevent dirt, deposits, and scale from forming or redepositing during washing is essential.

Brennsperse Dispersants and Antiscalants help remove and transport dirt, deposits, and scale during the cleaning cycle, keeping them dispersed in the wash water and not redeposited.

These polymeric additives are effective in the detergents and cleaners market with multiple functions similar to their use in water treatment.

Benefits for the detergents & cleaners market include:

Anti-redeposition: Dispersants keep removed soils entrapped in the wash water, preventing
the soil from redepositing back onto the clothing and preventing residues (spots) from
forming on hard surfaces.
Sequestrates: Dispersants prevent precipitation of inorganic salts such as carbonates,
phosphates, and silicates on the fabric or surface.
Spray Drying Additives: Dispersants improve the process of spray dry detergents by
reducing slurry viscosity, improving slurry (crutcher) homogeneity, and increasing solids of the
crutcher mix, reducing dusty fines, and increasing bead strength

When mining, the extraction of calcium, phosphate, kaolin, and sand often requires the minerals to be mixed with water to form a slurry.

A slurry is a mixture of a solid and liquid which has a natural tendency to separate. If separation does occur several transportation, storage, and manufacturing problems can arise, including difficulty pumping or problems with production.

Brennsperse Dispersants help with the free flow of slurries by dispersing the slurry solids to slow or prevent separation. As a result, this yields a more consistent slurry.

Four positive things happen when using dispersants in your mining and slurry treatment processes:

Drag Reduction: Dispersants reduce turbulence to allow for a more even flow.
Slurry Stabilization: Dispersants yield a more evenly mixed slurry.
Viscosity Improvement: Dispersants stabilize the overall viscosity of a slurry preventing
high and low viscosities.
Scale Control: Dispersants prevent scale formation which hinders operation.
