Wastewater Treatment Plant (WWTP)
FACILITY: Water and Wastewater Treatment Plants located throughout North America
PROBLEMS:
- Industrial and municipal wastewater treatment facilities require dependable, cost-effective space heating and make-up air heating systems.
- WWTP facility operators need safe, reliable heating/ventilating equipment that is energy efficient; has low maintenance costs and will last a long time in this harsh environment.
- Year-round ventilation with fresh outside air is required for areas that are exposed to raw sewage, poisonous hydrogen sulfide, volatile methane gas and fumes from caustic chemicals.
- Indirect gas-fired systems with heat exchangers require a flue, are not energy efficient and are subject to problems unless expensive corrosion-resistant tubes/fins are specified.
SOLUTIONS:
- Genuine Cambridgeฎ direct gas-fired space heaters and make-up air units are the most cost-effective and energy efficient way to provide heating/ventilating for water and wastewater treatment plant applications.
- Direct gas-fired Cambridge heaters do not require a heat exchanger or flue. This improves energy efficiency and lowers operating costs.
- The Cambridge stainless steel gas burner and stainless steel flame rod reduce maintenance costs and extend service life.
- Cambridge special solutions include cost-effective construction features to resist corrosion.
- All heaters use 100% fresh, non-recirculated outside air to provide required ventilation and improve indoor air quality.
- Space heaters with Blow-Thruฎ technology and make-up air heaters with variable frequency drive (VFD) controls increase energy efficiency and lower operating costs.
- Typical WWTP buildings/areas that use Cambridge heaters include: headworks building, sewage pump station, lift station, primary clarifier, sludge dewatering building, process sludge, activated sludge, plant water building, blower area, chlorine room and other applications.
RESULTS:
- Engineers, contractors and facility operators have specified and used dependable, energy efficient Cambridge direct fired heating equipment in wastewater treatment plant applications since the early 1980s.
- Case Studies document over 20 year service life in this harsh environment.
- Service contractors in the WWTP market now recommend Cambridge heaters as a cost effective replacement for inefficient indirect fired heating systems and inferior quality direct-fired heating systems that are unreliable and have high maintenance costs.
