B-Clear™ Clay-based Wastewater Treatment Chemistries

BJAAM offers a variety of clay-based chemistries consisting of proprietary blends of clay, acids, bases, polymers, and other additives. While mixing during the treatment process, these components activate rapidly with the wastewater based on their individual solubilities. Acids react first, breaking any oily emulsions, while the clays and polymers begin to hydrate and absorb the oils. The basic components then go into solution, raising the pH high enough to help remove any metals from solution. Additionally, metal ions become bound to the clay through the process of ion exchange. The oils and greases, metals and suspended solids are removed from the wastewater and fixated onto large floc particles through the process of flocculation and encapsulation. The treated water, which is largely free of oil, metals and suspended solids, can either be recycled or safely discharged into a municipal sewer. The entire treatment process is complete within minutes. Additionally, the residual floc with the encapsulated contaminants may be suitable for disposal in a non-hazardous industrial or sanitary landfill.

Wastewater Treatment Equipment Options

Traditional wastewater treatment systems are often multi-step, multi-tank operations requiring considerable time and extensive handling. BJAAM's unique treatment system involves adding a one-step semi-granular or granular chemical blend to the wastewater and mixing at high speed. Within minutes, the emulsion is broken, and the contaminants are captured in a clay-polymer floc, yielding a disposable, non-hazardous residual clay floc, and recyclable or sewerable water. Wastewater treatment is completed in a single vessel within minutes.

Package System

Package systems are "all-in-one" treatment units, consisting of a mix tank with water and sludge decant valves, a stainless steel bandfilter overlain with a disposable filter media, and a clean water collection tank. Mix tank sizes vary from 100 gallons to 1200 gallons, and system operation can range from manual to fully automatic. Throughput capacity can range from 100 gph to 3600 gph. Equalization tanks, post-filtration options and associated equipment are also available.

Component System

Component systems are designed around one of five standard mix tank sizes ranging from 500 to 4000 gallons, and include a sludge tank and filter press. System operation can range from manual to fully automatic. Throughput capacity can range from 500 to 4000 gph. Equalization tanks, pumps, level controls, pH controls, post-filtration options and chemical feeders are also available.

Encapsulation Fixates Waste for Safe Disposal. . . Economically!

For most traditional wastewater treatment methods, residual solids from these treatments are still classified as a hazardous waste. The unique chemistries used by BJAAM fixates waste through the process of encapsulation. The B-Clear^™ chemicals' special clay-polymer blends not only remove oil and metal contaminants from wastewater, but permanently coat, or encapsulate them. The encapsulation process produces a safe, non-leachable solid that, in many cases, can be disposed of in non-hazardous industrial or sanitary landfills. The costs associated with this type of disposal are several times less than those associated with hazardous waste landfills, and encapsulation virtually eliminates the possibility of groundwater contamination. We recommend that Toxicity Characteristic Leaching Procedure testing be completed on each residual solid to verify non-leachability.

As disposal costs for concentrates or sludges can vary widely, a BJAAM representative can assist in determining local disposal costs and regulations. In states where non-leachability studies are required for sludge re-classification, a BJAAM representative can likewise provide assistance.

Flocculation

Laboratory and Consulting Services

BJAAM utilizes a laboratory capable of analyzing your wastewater and assessing the feasibility of treatment using BJAAM's treatment systems. BJAAM will recommend a treatment system and provide before and after treatment analysis. Based on the composition of your wastewater and the volumes generated, BJAAM will recommend a system to meet your specific needs. With a portable unit, BJAAM can demonstrate the treatment process on-site, conducting a pilot study to verify dosage rates and treatability.
