Wastewater treatment high rate algal ponds (WWT HRAP)
Growing energy demand and water consumption have increased concerns about energy security and efficient wastewater treatment and reuse. Wastewater treatment high rate algal ponds (WWT HRAPs) are a promising technology that could help solve these challenges concurrently where climate is favorable. WWT HRAPs have great potential for biofuel production as a by-product of WWT, since the costs of...
In this perspective, microalgae can be grown as by-products of wastewater treatment in high rate algal ponds (WWT-HRAP), which are shallow (30-40 cm deep), paddlewheel-mixed open raceway ponds
Wastewater treatment high rate algal ponds (WWT HRAP)
Wastewater treatment high rate algal ponds (WWT HRAPs) are a promising technology that could help solve these challenges concurrently where climate is favorable. WWT HRAPs have great potential for biofuel production as a by-product of WWT, since the costs of algal cultivation and harvest for biofuel production are covered by the wastewater
Currently despite intense efforts algal biofuel production is still not economically competitive with fossil fuel. To lower algal biofuel production costs, replacement of pure algal biomass with free gravity-harvested algal-bacterial biomass produced in wastewater treatment high rate algal ponds (WWT HRAPs) has been suggested as a niche opportunity.
Wastewater treatment and algal production in high rate
This research shows that the wastewater treatment HRAPs with CO 2 addition achieved a mean algal productivity of 16.7 g/m 2 /d for the HRAP 4d (4 d HRT, maximum algae productivity of 24.7 g/m 2 /d measured in January 08) and 9.0 g/m 2 /d for the HRAP 8d (8 d HRT)).
Wastewater treatment HRAPs are normally part of an Advanced Pond System which typically comprises advanced facultative ponds which incorporate anaerobic digestion pits, HRAP, algal settling ponds and maturation ponds in series (Craggs, 2005, Craggs et al., in press). Based on design for BOD removal, Advanced Pond Systems require approximately
Pyrolysis of wastewater treatment high rate algal pond
Therefore, to reduce the cost of algal biofuel, the use of algae that is a by-product of wastewater treatment in high rate algal ponds (WWT HRAP) has been suggested . Several studies have shown WWT HRAP biomass productivities of 20–60 t/ha/year, consisting of 60–80 wt.% algae, 20–30 wt.% bacteria, and 5-10 wt.% other organic matter [10
