Abstract

A nutrient system for automatically supplying growth medium to an algae growth system comprises a tank for mixing nutrients, together with a plurality of computer-controlled pumps for supplying metered amounts of selected constituents to the tank. The nutrient mix is heated to a preselected temperature under computer control, and recirculated until the desired uniformity is achieved. The nutrient mix is then supplied to the algae growth system.

Claims

1. A nutrient system for automatically configuring growth medium for algae strains comprising

a tank for receiving nutrients,

a plurality of reservoirs of mix components, and

a plurality of computer controlled metering pumps for selectively adding nutrients to the tank.
