Advanced Arsenic RemovalBlue Water Technologies, Inc. is the industry leader in cost-effective adsorption technologies for contaminant removal from water. With advanced control techniques and patented treatment systems, Blue Water can provide you with a cost effective solution to meet your arsenic removal needs.

The Blue PRO® system does not require pre-manufactured adsorptive media and provides a unique approach to chemical dosing, with significantly lower chemical use across the system than competitors. Usually only one low reagent dose is required to achieve the lowest arsenic discharge requirements. Current Blue PRO® installations are meeting permit limits as low as 0.01 mg/L with a chemical dose of only 2 mg/L as Fe. Blue Water’s unique chemical control system provides an advantage due to its cost efficiency and ability to seamlessly integrate into and respond to the needs of existing water treatment systems.

Blue Water understands the geochemistry parameters critical to the optimization of arsenic removal systems, including oxidation-reduction potential and pH. Blue PRO® is unique in accomplishing treatment goals, even for arsenite, often without the need for extra pre-oxidation or pH change steps.

The Blue PRO® SystemHow does Blue PRO® work? Using Blue Water’s Centra-floTM continuous backwash gravity sand filters, a unique control system, and the patented Blue PRO® process for reactive filtration, arsenic is removed from water streams through an array of mechanisms. Most importantly, Blue PRO® optimizes adsorption.

Blue Water’s reactive filtration process overcomes a critical obstacle to achieving efficient arsenic removal in bulk aqueous solutions by providing reactive surface sites within the media bed, resulting in forced contact of chemical species with high adsorptive capacity. The adsorptive surface in Blue PRO® filters is a continuously regenerated hydrous ferric oxide (HFO) coating that forms on the surface of the sand media. Other treatment options simply cannot compare to the efficiency of adsorptive arsenic removal coupled with continuous regeneration of the adsorptive media.

Waste HFO, arsenic, and solids are removed from the filter through the backwash or reject stream. The arsenic is chemically bound to the iron and easily settled out for disposal. The media never needs to be replaced. Blue PRO® uses over 30% less chemical than coagulation-filtration technologies, therefore producing less sludge. The waste solids pass TCLP tests.

Blue PRO® Applications:

• Advanced arsenic removal

• Other metals removal, including mercury

• No media replacement

• 5 gpm to multi-MGD systems

The Blue PRO® system is available in several models and configurations. The modular nature of the filters allows for easy system expansion. The filters are available as freestanding fiberglass or stainless steel units or as in-ground concrete cells. Control systems and smaller filters may be skid mounted for mobility or ease of commissioning.

Additional FeaturesBesides arsenic, Blue PRO® is effective at removing many other contaminants, such as mercury, chromium, uranium, and nutrients. Minor adjustments in water chemistry may be implemented for the removal of some metals and other contaminants, including zinc, lead, copper, iron, and manganese. Blue Water has installations for removal of these contaminants in wastewater plants as well as groundwater systems, including self-contained package treatment systems.

Blue Water’s Blue PRO® technology is covered by multiple patents and patents pending.
