THE CLEAN EARTH SOLUTION
Clean Earth has been in operation since 2000, providing wastewater dewatering and residual management services to residential, commercial and industrial markets. Our two locations provide sludge de-watering for residential, commercial and industrial septic and waste haulers in South-Western New Brunswick. Clean Earth Ltd. de-waters the sludge passing grey water to municipal systems and transporting the biosolids for disposal, usually at composting facilities.
THE CLEAN EARTH PROCESS
Each of the two facilities has the basic layout.
- A computer controlled 24/7 access allows haulers to come in whenever they want to dispose of their waste. Each company/driver has a smartcard to enable access, associate each load to a driver/company and differentiate waste streams. This is technology developed by Clean Earth Ltd.
- Each load of waste is metered and Clean Earth charges a specific amount per gallon which depends on the type of waste. The hauler receives a ticket indicating the date, time, company, and amount unloaded.
- The waste goes through a bar screen, into a receiving pit with a weir. The weir keeps sand, rocks, and debris on the weir side with the waste flowing over into a pump chamber where the waste is pumped through a grinder and into a holding tank.
- The holding tank keeps the solids suspended with mixers until the operator is ready to process through the Fournier Rotary Presses. Fredericton has a total holding capacity of 170,000 gals while Saint John has a total holding capacity of 300,000 gals.
- When the press is started, a submersible pump pumps the waste back to the process building where a polymer is added for flocculation.
- The separation takes place in the press with the effluent water going into the municipal wastewater system and the solids going into a roll on-roll of container.
- The solids are taken to a compost company where the dewatered
- Biosolids are used as a feedstock for their process.
