PFAS

BCA is building out the PFAS remediation and destruction practice focusing on wastewater treatment facilities. We are working with two companies that jointly own patents to remediate and destroy PFAS chemicals according to the following outline:

The patented chemical additive combined with a Lanthanide solution is a simple, continuous, addition of natural mineral compounds. Lanthanides are the most powerful “safe” substances available in nature and we have the patent on this technology. The solution is a complex blend of naturally occurring elements. The elements include Alkaline Earth Elements, Alkali Metals, Transition Metals, and Non-Metal Elements, as follows: The primary elements are Magnesium, Calcium, Carbon, Sodium, Potassium, Iron and Oxygen. It also includes Chloride, Sulfite and Fluoride in trace amounts.

The additive is a complex blend of naturally occurring elements with extraordinary synergy for remediating wastewater. It affects the environment of wastewater systems, creating a floc so tough that it will floc again and again after shearing, even in recirculation. The complexity of the composition creates attractions we haven’t seen in any other chemical or reagent. The composition is so effective that some treatment plants have even eliminated their chemical treatments altogether. The solution will not “load-up” and comes complete with five catalysts designed to remediate any type of wastewater.

The Spiral Filter Press mounts on top of the Dehumidification unit and excepts sludge with solids as low as 1% and as high as 5%. This slow-moving system delivers cake at a consistent 20% solids to the dehumidification / drying unit without the need for adjustment with the filtrate water being sent back to the plant for treatment.

The dehumidification heat pump cycle is the most efficient way to dry sludge using hot air closed conventional recycling, condensing, dehumidifying and drying. Low Temp Drying from (104-158F) in our closed cabinet produces no odor.

These heat pump dryers are self-contained, insulated, closed loop systems where the air in the dryer is not released out of the drying cabinet making them the most energy efficient dryers in the world. These units dry the sludge using the heat pump cycle instead of burning fuel oil, or natural gas. Solar PV Panels can be installed, and grid tied to generate the electricity needed to operate the heat pump cycle and the moisture released from the organic cell is condensed and sent back to the headworks.

The dehumidification heat pump used in the dryer utilizes the refrigeration principle to cool and dehumidify hot wet air. Through the heat pump principle, the heat pump recycles the latent heat released from steam congealing to water liquid. A dehumidification heat pump is equal to the dehumidification process (moisture removal or moisture dehumidifying) plus a heat pump process (energy recycling). A dehumidification heat pump can internally collect all the latent heat and sensible heat during air exhaust, bringing no waste heat to the outside.

The evaporation of sludge moisture absorbs latent heat, and the condensation of the generated vapor on the heat pump cycle releases latent heat. The evaporation process absorbs the same quantity of latent heat that the condensation process produces, according to the laws of thermodynamics and the law of conservation of energy. As a result, the drying process does not require additional heat capacity, resulting in the reduction of energy costs. The energy consumed during the process is only the electricity needed to operate the compressors and the air handlers.

The plasma gasification system is simply the most cost-effective way of destroying the PFAS/PFOS compounds in bio-solids. This unit uses a Plasma Gas to get to the temperatures required (simple gasifier, or incinerator will not work unless extra carbon and oxygen is added into the burn chamber).

Utilization of plasma magnetic field (hot ionized gas consisting of approximately equal numbers of positive ions and negative electrons) to create activated negative ions that leads to decomposition of inorganic and organic materials through the process of pyrolysis (thermal degradation of substance in the absence of oxygen at high temperature up to 1600 degree Celsius). This breakthrough innovation has enabled continuous self-combustion process without the need of external energy sources (diesel, carbon fuels, electricity).
