Liquid Asset Development, LLC

Liquid Asset Development (LAD) LLC licenses an innovative process to design and fabricate water filters out of concrete. Each licensing agreement includes full disclosure of the design and fabrication process.

There are two models of these filters, one for humanitarian use and the other for more robust applications. Research began in 2006 and two prototypes have been built and tested with financial assistance achieved through a US EPA grant. The goal of this research was to develop a water filter using a medium that was globally available, required minimal training for others to design and assemble and could take advantage of existing manufacturing facilities. This means that countries with only rudimentary industrial infrastructure and education systems can be empowered to improve their own water quality without needing to rely on foreign financing or foreign production and companies can do the design work in-house and contract out production. And the reduction of import/export activity means that each licensee reduces their carbon footprint. And due to the low unit cost of the filters, recycling is an economically viable option as is destroying the filters to recover filtered metals.

Industries: Desalinization

1. Enhance removal of large particles such as organisms and sand.2. Extend the life of other pre-treatment filtration mechanisms.3. Recover dissolved metals for resale on the open market.

Acid Mine Drainage 1. Recover dissolved metals for resale on the open market.2. Increase dissolved oxygen concentration.

Agriculture (surface runoff)1. Reduce/remove phosphates and nitrates from fertilizers and manure.2. Trap colloidal material such as soil, plant matter, manure.

Humanitarian1. Disinfection/filtration of microorganisms.2. pH based neutralization of arsenic and fluoride toxicity.3. Chemical treatment of odors.4. Physical filtration of oils and colloidal material.

Advantages: Complete ownership of the design and fabrication process. Concrete infrastructure and expertise is already in place globally. Extremely low material cost. Modular design allows for flexibility in treating varying flow rates with varying pollutant

types/concentrations and varying geography as well as allowing manual labor to be used. Can be 100% recyclable, which also reduces the need to mine aggregate. Being recyclable and no need to import the units make this filter very sustainable.
