Industry news and updates from ROHES on biosolids management, land application and wastewater solids in Ontario.
Company news and industry background on biosolids management in Ontario.
Sub-surface injection of biosolids places material below the soil surface rather than on top of it. In practice this cuts odour markedly, applies material at a uniform rate across the full width of the implement, and aerates the soil as the tines pass through. Together these effects have made injection the method of choice for farms close to residential development.
An analysis comparing the delivered cost of conventional fertiliser against that of land-applied biosolids. The conclusion drawn was that where biosolids are readily available, the lower delivered cost of biosolids can offset yield gains from commercial fertiliser — savings partly eaten up by lower yields. Reported by the Ontario Farmer, 8 March 2005.
ROHES underwent a facility audit by the Ontario Ministry of Transportation, receiving an overall rating of 95.8%. The Registrar of Motor Vehicles also awarded the company an “Excellent” safety rating under Section 17.1(1) of the Highway Traffic Act.
ROHES manages nine membrane-lined storage cells, giving clients capacity through winter and inclement weather when land application is not feasible — and meeting the storage requirements that came with Ontario's Nutrient Management Act.
In response to falling demand for surface application and rising farmer interest in sub-surface injection, ROHES added a second AerWay SSD injection unit to its equipment.
