Nothing on the market delivers high quality reusable water at our lifecycle costs

With local sourcing of materials and 80% reduced energy costs and very low maintenance burden, this affordable decarbonised system is what communities with limited resources have been waiting for. Every cubic meter of ALGAESYS water and biomass provides opportunities for local wealth creation.

ALGAESYS is a net energy producer

 

The majority of ALGAESYS processing energy needs come from the sun, and the small amount of electrical energy (c. 0.2 kWh/m3) could be provided by photovoltaics. ALGAESYS biomass has a high energy yield that could provide local energy autonomy and used in CNG vehicles, for firing boilers, injected into local gas networks or converted to electrical power.

ALGAESYS feeds horticulture, ensures food security

ALGAESYS enables the circular economy.

The safer, reliable and cost-effective reuse of water for irrigation and biomass as soil conditioner, due to robustness of algae with higher protection from toxins entering the food chain. 

The EU Water Framework Directive encourages reuse for horticulture even in non water stressed regions.

The ALGAESYS system

  • removes nitrogen, phosphorus and carbonaceous pollutants

  • absorbs micro-plastics and heavy metals

  • destroys persistent organics,

  • disinfects to at least EU Class C without additional treatment

  • absorbs atmospheric carbon dioxide, approximately 15 grams per cubic meter of wastewater treated

 

Phototrophic biofilms are especially interesting for wastewater treatment and are a more sustainable alternative to existing bacteriological wastewater treatment systems due to robustness and energy efficiency. 

In existing wastewater treatment systems, the organic pollutants are oxidised by heterotrophic microorganisms, a process that requires energy consuming oxygenation through aeration and costly additional process steps for disinfection and removal of persistent organic chemicals. 

ALGAESYS uses naturally occurring colonised phototrophic biomass that

  • Produce reactive oxygen species to remove pathogens and oxidise persistent organics such as trace organics, hormones, pharmaceuticals, and endocrine disruptors.

  • Produces extracellular polymeric substances that provide far more effective toxic shock event survival than conventional bacterial systems. These polymeric substances also enables establishment of the colony that attaches to our rotating logs, inducing optimal conditions to maximise biomass efficacy in breaking down and oxidising pollutants.

 

This mechanism results in considerable savings on energy, equipment, labour and maintenance. 

The patented ALGAESYS technology has been developed and extensively demonstrated at full-scale in the USA and further optimised in China and our EU demonstration facility is being implemented

INDIANA, U.S.A. - The Summit Lake State Park facility with capacity of 275 cubic meters per day.  This replaced an older 200 m3/d facility.  It took 8 weeks to build of which 2 weeks were for concrete curing and our installation of 3 weeks.

Operating continuously since treatment license issued in 2015, the Department of Natural Resources reported in 2020 that the "the treated wastewater quality is well within current discharge limits, which were significantly tightened" and that  "in terms of operability, all the rangers' reports are excellent in terms of ease of operations". Their letter also stated that they are "happy to recommend this treatment system".

WORLD ECONOMIC FORUM UPLINK - ALGAESYS is an UPLINK TOP INNOVATOR and was winner of the WEF Uplink Circular Water Cities Challenge - and has been joining Uplink events at COP26, Glasgow 2021 and the UN Ocean Conference 2022.

EDIBLE LONDON is spearheading a revolution towards a fair food economy in which food is available and accessible to all, whilst fostering resiliency in our communities.  EDIBLE's leadership is working with ALGAESYS to realise water reuse in horticulture to sustain local communities in various parts of the world including the Eastern Mediterranean.

BLUE BIO ALLIANCE - ALGAESYS is a member of the Blue Bio Alliance based in Portugal which promotes the blue (marine) economy.  Our co-founders attended the Blue Bio Value accelerator programme in 2019, sponsored by the Calouste Gulbenkian Foundation and Ocean Azul.

IMOPLASTIC GROUP - ALGAESYS commissioned IMOPLASTIC Group of Marinha Grande, Portugal, to fabricate the steel injection mould tool now being used to produce components for the rotating carrier onto which the algae and other phototrophic organisms adhere, slowly rotating into and out of the bioreactor in alternating dark-light cycles. IMOPLASTIC are also fabricating other key components for ALGAESYS.  See the mould here.

ECEP - ALGAESYS system photo bio-reactor stainless steel tanks are fabricated by ECEP based in Oia, Portugal.  See the tanks being wet tested here.
