Eco-Tec’s TriFlo Demineralizer produces the ultrapure water (i.e. conductivity of less than 0.1 μS/cm) often required to feed critical and super critical boilers. This is achieved economically with stable and robust process equipment from feed water containing up to 450 ppm of total dissolved solids. Ultrapure water can be achieved by simply adding an additional cation resin bed as a polisher after the usual two-bed demineralizer to remove residual sodium ions. The TriFlo Demineralizer can provide solutions for applications requiring high purity water in the range of 10 – 18.0 ohm.cm resistivities.

The BgPur system is our proven solution for biogas treatment from anaerobic digesters and landfill. The system reduces hydrogen sulfide (H2S) concentrations and converts it to solid elemental sulfur for resale. The system uses a liquid chemical catalyst, compact gas/liquid contactor, and solids removal system and does not consume the chemical catalyst driving the conversion of H2S to sulfur, minimizing chemical make-up requirements. As a result, operating costs are significantly lower than typical solid sorption processes and the system promotes a stable and predictable H2S removal process.

The SgPur system is specifically designed to treat sour gas from oil and gas operations. The system reduces hydrogen sulfide (H2S) concentrations and converts it to solid elemental sulfur for resale. The system uses a liquid chemical catalyst, compact gas/liquid contactor, and solids removal system and does not consume the chemical catalyst driving the conversion of H2S to sulfur, minimizing chemical make-up requirements. As a result, operating costs are significantly lower than typical solid sorption processes and the system promotes a stable and predictable H2S removal process.

Etching or chemical milling with caustic soda can often be the greatest operating expense in aluminum anodizing. Our CER Caustic Etch Recovery System continuously crystallizes and removes dissolved aluminum from caustic soda etchants and returns the caustic to the etching/milling tanks for reuse resulting in reduced chemical costs, waste treatment costs, and labor requirements. The separated aluminum trihydrate crystal contains a marketable and salable value.

BgPur is Eco-Tec’s proven H2S removal system for treatment of biogas from anaerobic digesters or landfills. The system is capable of treating biogas with H2S concentrations of a few hundred ppmv to over 30,000 ppmv (3%) while reducing the H2S to a just a few ppm to meet downstream requirements for power generation or heating fuel, or to be sold for pipeline or transportation fuel.
