Abstract

Spent anaerobically digested effluents of agricultural origin were collected and treated using membrane filtration to achieve three- large particle free- nutrient streams of N:P ratios of 16.53, 3.78 and 14.22. Three algal species were grown on these streams, achieving good levels of bioremediation...
