Successes In Increased Water Quality
ENVIRO
Case Study 1
Vordingburg Harbor Denmark
ENVIRO is a physio-chemical water treatment system patented by Waterneer Technologies, Inc. and jointly commercialized by WTG in the USA
Customer needed a dredging solution in contaminated Salt water.
The debris from bottom of the harbor was pumped into ENVIRO. The sludge was separated and hauled away.
The ENVIRO Tech system removed the wastewater of heavy metals and other contaminants.
The treated effluent met all environmental standards of Denmark and clean water was released back into the harbor.

Case Study 2
Produced Wastewater
A facility separated produced water (petroleum laden wastewater) using thermal separation.
Process required 2-3-person days per week maintenance to remove solids buildup in HX.
ENVIRO was able to remove solids and treat water for discharge standards.
| Inlet Value of Produced Water (TSS) | Outlet Value of Produced Water (TSS) |
| 353 ppm | <10 ppm |
Case Study 3
California Dairy Farm
ENVIRO treats wastewater directly from dairy lagoons (ponds).
Sediments are removed for nutrient management and effluent meets standards for agriculture use.
Results:
99.9% Removal of Solids
96% Removal of Phosphorous
60% Removal of Nitrogen and TKN
Met Agriculture Reuse and Groundwater Recharge Standards
Inlet From Dairy Lagoon
Outlet From Dairy Lagoon
Case Study 4
Boliden Zinc Mine, Sweden
Arsenic Reduction – 99.9%
Manganese Reduction – 98%
Chromium Reduction – 99%
Cadmium, Copper and Other Heavy Metals All 99% Reduction
Case Study 5
