NVP Energy Limited has developed an innovative Low Temperature Anaerobic Digestion (“Lt-AD”) wastewater treatment process that addresses mandatory treatment for low strength, low temperature wastewater at a fraction of the cost of other wastewater treatment technologies. In addition, while alternative wastewater treatment technologies require a large footprint, have high energy costs and offer no payback to the customer, NVP Energy's solution has a modular compact plant footprint, offers dramatically reduced operating costs (up to 60%) and generates sufficient energy as a by-product to generate revenue and thereby to offer a payback on capital spend averaging 3 years.
The Company’s technology has global application through its unique energy positive low temperature Anaerobic Digestion process which treats wastewater at temperatures below 20°C (unique for AD technology). Its prospective customers are in the global Food & Drink Industries (Dairy, Meat Processing, Brewing, Distilling, Malting, Bottling, and Pharma) and also the global Municipal Wastewater industry.
NVP Energy offers a solution to enable customers to significantly reduce their OPEX expenditure on wastewater through reducing the chemical oxygen demand (COD) and total suspended solids (TSS) concentrations in their effluent with minimum operating costs and utilising a usable, revenue generating, biogas by-product. The technologies currently employed for low temperature, low strength wastewater treatment are Aerobic Activated Sludge treatment or Membrane Bio-reactor treatment. Both technologies are well understood and market accepted but due to their high operational costs offer no, or an unacceptable, payback period.
NVP Energy, by comparison, offers customers the opportunity to benefit from:
• Reduced energy input costs (due to its operation at low temperature);
• Substantially reduced trade effluent charges where these are applicable;
• Vastly reduced costs of sludge removal due to the process producing minimal sludge; and
• A by-product of high quality biogas that is available for reuse by the customer to generate heat and/or electricity on site.
As a result, customers can convert wastewater treatment from being an operational cost into a new revenue stream. NVP Energy’s wastewater treatment occurs at ambient temperatures without loss of efficiency, requiring no additional heat input and allowing NVP Energy’s solution to work at very short Hydraulic Retention Times (HRT) of only 8 to 12 hours.
