Saltworks developed a cost-optimized solution for fluoride removal using our BrineRefine advanced chemical precipitation and XtremeUF ceramic ultrafiltration systems. An example process flow diagram is presented in the figure below. The combination of BrineRefine and XtremeUF in calcium fluoride precipitation and coagulation eliminates the need for large clarification/sedimentation tanks and multimedia filtration and/or cartridge filtration, reducing footprint, maintenance and operating costs.

What is anti reflective coating on lensesreddit

Heavy industry, manufacturing, and natural resource-based industries often use large volumes of water and generate wastewaters requiring treatment. Saltworks designs, builds, and operates advanced wastewater treatment plants that economically and reliably treat tough industrial wastewaters.

BrineRefine is an improvement to existing chemical precipitation for fluoride removal. BrineRefine uses intelligent controls for automated precise dosing, avoiding lime and calcium chloride under/over-dosing to precipitate CaF2. XtremeUF is an ultra-robust ceramic ultrafiltration system that self-cleans while it operates. XtremeUF filters the CaF2 and Al(OH)3 fine particles from the coagulation process, leaving a clean water filtrate that could be discharged or reused directly in hydrofluoric acid etching of semiconductors. BrineRefine and XtremeUF are fully integrated into a single smart and automated plant.

Anti glare glasses, or lenses treated with Anti glare coatings, also known as anti reflection, reflection free, AR or MAR coatings, were developed to reduce reflections for camera lenses and have now become available for prescription glasses lenses.

Calcium fluoride precipitation can reduce the fluoride concentration down to about 8–20 mg/L, depending on the total dissolved solids concentration in the wastewater. A second coagulation step, using aluminum-based coagulation agents, is required to further reduce fluoride to less than 5 mg/L.

During CaF2 precipitation, lime is used to neutralize any waste acids in the fluoride wastewaters. With fluoride concentrations less than 1,000 mg/L, lime is often selected as the sole calcium source to precipitate fluoride. Lime has a low solubility at 0.18% by weight so for wastewater with high fluoride concentrations it used together with calcium chloride, which has a high solubility. Excessive lime addition often results in undesired consumption of aluminum coagulants in the downstream coagulation step and increases sludge quantities.

In the microelectronics industry, fluoride wastewaters are generated during hydrofluoric acid etching of semiconductors. Hydroflouric acid is also employed in the solar cell and metal-plating industries. Typical concentrations of fluoride in these wastewaters can range from 100 mg/L to more than 10,000 mg/L. In general, fluoride discharge limits are less than 20 mg/L if the wastewater can be discharged into a public sewer system, and less than 5 mg/L if the wastewater is discharged into an aquatic environment. In some jurisdictions, the fluoride discharge limit can be less than 2 mg/L. It is noted that some municipalities add fluoride to drinking water (0.5–1.5 mg/L) because of its beneficial prevention of dental cavities. However, excessive fluoride is harmful to human health causing skeletal fluorosis (bone disease).

A Kubec · 2022 · 31 — Diffractive and refractive optical elements have become an integral part of most high-resolution X-ray microscopes.

The calcium fluoride precipitation and coagulation method, however, has two disadvantages: 1) CaF2 from the precipitation step and Al(OH)3 from the coagulation step are both very fine particles, so their sedimentation and clarification times are very long, requiring large footprint clarifiers; and 2) overdosing of lime and coagulation reagents results in a higher chemical cost and a large volume of wet sludge for final dewatering treatment.

Anti reflection coatings are available for all lens options and designs, such as varifocal lenses, high-index lenses, polycarbonate lenses, photochromic lenses and polarised lenses.

False light in office surroundings can quickly cause eye fatigue and working on a computer can also put significant strain on the eye. Having an Anti-glare coating will protect your eyes whist working due to the decreased glare, and therefore result in less eye strain.

Existing removal options for fluoride wastewaters include: 1) calcium fluoride (CaF2) precipitation and coagulation, 2) adsorption, 3) ion-exchange, and 4) membrane-based processes such as reverse osmosis and electrodialysis. An industrial wastewater with a high fluoride concentration is often treated through the CaF2 precipitation and coagulation method. Adsorption, ion-exchange, and reverse osmosis are more often used in drinking water applications and for final fluoride polishing.
