LiqTech International, Inc. And Constructora Conconcreto Today Signed An Exclusive Agreement For Colombia And Venezuela


BALLERUP, Denmark, Nov. 5, 2012 /PRNewswire/ -- LiqTech International, Inc. (OTCQX: LIQT) ("LiqTech") announced today that it has entered into a close cooperation agreement with Constructora Conconcreto South America with exclusivity in Colombia and Venezuela following the successful 12-month trial period with LiqTech's ceramic membranes for water filtration in the Oil and Gas industry. The trial period was followed up with a commercial agreement between Conconcreto and Hocol for operation of a SiC membrane installation for produced water treatment, marking the commercial breakthrough for this market.

Constructora Conconcreto SA operates as an engineering and construction company in Colombia and internationally. The multibillion dollar Company's stock trades on the Bogota exchange under the symbol CLB: CO:CONCONCRET. The Company designs, builds, maintains, and operates tunnels, bridges, airports, power plants, roads, interchanges, and mass transit systems. It also builds industrial, commercial, institutional, and housing projects; production plants, electric substations, slipped silos, wharves, warehouses, universities, libraries, entertainment centers, sports venues, hotels, hospitals clinics, and cultural centers. In addition, the company executes civil works and installation of electromechanical equipment in large plants; and provides promotion and planning services for third parties. Conconcreto S.A. is headquartered in Medellin, Colombia.

Conconcreto CEO, Mr. Juan Luis Aristizabal, stated, "LiqTech has a cutting edge technology for a fast growing market for industrial water treatment in our region. LiqTech is dedicated to innovating new environmentally friendly products. Their SiC Membrane is by far the best product in the market and we have high expectations to our success in produced water."

CEO of LiqTech International, Mr. Lasse Andreassen, commented, "Conconcreto is a leading construction company in the region with close ties with large companies in the Oil & Gas and mining industries. Conconcreto has exhibited strong growth for the last decade which makes it uniquely positioned to deploy our technologies in the region. Conconcreto's commitment to preserving the environment fits well with our SiC membranes." 

Conconcreto has been actively working to validate the LiqTech ceramic membrane technology for the Oil and Gas industry during the last twelve months and has successfully concluded field trials with Hocol (subsidiary of Ecopetrol) in Colombia.

The field trials included replacing flotation units and walnut shell filters for polishing of Produced Water for re-injection purpose. The performance delivered by the Conconcreto solution for Produced Water treatment exceeded the standards of the Colombian legislation and the expectations of the oil company. The SiC membranes were operated upstream and downstream of a skimmer unit and both operations showed remarkable performance. Typical membrane feed water with oil concentration of 20-100 ppm was consistently treated to less than five ppm oil in water for re-injection purpose (95% of the time below 0.7 ppm oil in water). The production capacity per unit membrane surface area was in the range 200-350 L/m2.h when operating prior to a skimmer unit and even 400-600 L/m2.h when operating downstream of the skimmer unit.

Conconcreto is currently certifying LiqTech's Silicon Carbide (SiC) membranes with INTEVEP for the oil and gas market in Venezuela.

Besides the Oil and Gas industry, Conconcreto has identified new business opportunities for other water treatment markets. Conconcreto is producing water treatment systems to meet orders received from mining, potable water and industrial wastewater demand.

Conconcreto and LiqTech believe strongly in the potential of this technology and its environmental benefits compared to existing solutions with regards to energy and chemical consumption, reduced footprint and ease of recycling.  Both companies expect a fast growing market demand for water treatment technologies especially for LiqTech's environmentally friendly SiC membranes.
