Overview

The Algal Scientific Hypertrophic™ Water Treatment Process uses a single-step to remove soluble organics (BOD/COD), nitrogen, and phosphorus from medium to high strength wastewaters. Our process relies on the unique biology of microalgae to simultaneously remove all three water contaminants.

Simply put, rather than allowing an algal bloom to occur in nature, where it causes significant environmental and economic damage, we create a controlled algal bloom in compact growth troughs. We then separate the algae from the water, producing clean water to meet the regulatory requirements of our customers or reduce the surcharges they pay, and create a biomass resource we will process and market reducing costs to our customers. This process is distinct from traditional systems which rely mainly on bacteria to remove BOD, and then chemical treatments with additives to aid in the physical removal of other nutrients. In short, we use the same proven wastewater treatment processes and equipment with a more advanced micro-organism. Our patent pending technology includes the specific types of algae we use and the processes for growing and harvesting it.

Features & Benefits

For the agricultural, commercial, industrial or municipal customer, compared to the traditional multi-step process, we have the technology to deliver better performance, at lower cost, with an easier to implement and operate solution.

Fertilizer and Protein Co-products

Our patented Hypertrophic™ process for high strength water treatment consists of open fermentation. This means that we maintain reactors that can be simple lined ponds, in ground concrete tanks, or above ground metal tanks, that have a community of heterotrophic microbes including our selected algae.

We may recommend the use of relatively small tanks holding a starter community of algae that use both photosynthetic and heterotrophic growth as an onsite source of these microbes, the main production reactors rely principally on heterotrophic growth.

The primary goal of these systems is to reduce the levels of biochemical oxygen demand (BOD), nitrogen and phosphorus to meet discharge limits and reduce surcharge costs for industrial process water. The preferred types of process water have high BOD and are produced in an organic process such as food and beverage processing. Ideally these process waters are the byproducts of a food processing step and are “food grade” without contamination from human or animal waste, heavy metals, or toxins.

The Hypertrophic process uses the unique biology of our preferred microbes (algae and eukaryotes) to grow on the nutrients in the process water at a high rate, removing these nutrients in the process. In contrast to traditional bacteria systems that attempt to minimize the production of biomass given it has low or negative value, our process optimizes the growth of biomass. This in turn produces higher quality water for discharge and possible recycling, while creating co-products with the potential to further lower treatment costs.

In the open fermentation process, we don't seek to produce a monoculture of a particular species, but allow the system to optimize itself based on the characteristics of the process water. We do use process controls and techniques covered by our issued and pending patents to both maximize the treatment efficiency and maintain the desired community and minimize undesired species.

We are currently targeting two primary product lines from this process:

Algapro™ - Algapro products are a dried and ground mixture of our biomass community. Its primary value is as a source of up to 45% highly digestible single cell protein.

Algagro™ - Algagro is an algae-based organic slow-release fertilizer.
