Two innovative membrane technologies: Liqocap® & LiqoVibro

_____

 

The Liqocap® and LiqoVibro membranes are the key components of the Liqoflux solutions to effectively separate the algae from the water. Liqoflux selected the right filters for algae pre-concentration, algae harvesting and water purifying and recycling. Both filters technologies are selected with the algae specific requirements in mind: stable flux, minimal fouling and reliable retention of algae cells.  

The Liqocap® capillary filters are mainly suitable when the (1) concentration of the algae culture is low and/or (2) larger volumes of algae culture have to be harvested. As all other capillary filters, the membrane serves as a selective barrier. The Liqocap® filters contain capillaries with modified Polyethersulphone (PES), increased inner diameter and pore size of 0,02 micron. 

The new LiqoVibro membrane technology is especially suitable for (1) harvesting algae cultures with higher concentrations (e.g. algae production with Photo Bio Reactors) and/or (2) harvesting algae cultures to higher end concentrations of 100 – 150 grammes per liter. The LiqoVibro membrane plates with pore sizes varying from 0,08 – 0,2 micron are vibrating relative to the media.

 

What differs Liqocap® capillary filters and the LiqoVibro membrane modules from the competition is:

  • High operating reliability;

  • Long service life with low maintenance;

  • Good antifouling properties;

  • Tolerance over wide pH range;

  • Easy to clean; 

Based on client’s data, together with our membrane partners, we are striving for continuous improvements on the Liqocap® filters and LiqoVibro membrane modules.

 

 

Algae harvesting: Liqocap algae pre-concentration system to separate the ‘easy’ water

_____

 

Thee Liqocap® capillary filters are mainly suitable when the (1) concentration of the algae culture is low and/or (2) larger volumes of algae culture have to be harvested (algae ponds). In harvesting high volumes of algae cultures the challenge is to process the high volumes in a limited timeframe and, at the same time, optimise the algae harvesting costs. To optimise the algae harvesting costs we advise a 2-step algae harvesting solution with the Liqocap filters:

 

Step 1 

Start with the Liqoflux algae pre-concentration system to separate the ‘easy’ water (more than 95% of the water!) and pre-concentrate the algae culture up to 10-30 gr/liter or higher. The clean water, free from algae cells and bacteria is ready for recycling to your algae production system.

Step 2 

Select the right separation technology (*) to separate the ‘difficult’ water and produce a high dry solid algae paste. The effluent of the centrifuge contains the ‘lost’ algae cells and can be recycled back to step 1. This process harvests 100% of the algae biomass!

Algae harvesting: LiqoVibro algae harvesting system for higher end concentration

_____

 

The innovative LiqoVibro membrane technology is especially suitable for (1) harvesting algae cultures with higher concentrations (e.g. algae production with Photo Bio Reactors) and/or (2) harvesting algae cultures to higher end concentrations. With the LiqoVibro membrane technology, where membrane plates are vibrating relative to the media to improve the filtration performance and reduce the fouling, you can reach algae concentrations up to 100-150 grammes per liter. The LiqoVibro technology is a smooth algae harvesting technology with low energy consumption, also very suitable for fragile algae cultures.

The LiqoVibro technology utilizes Free Flow membrane plate modules of 2,5 m2. These membrane modules will be combined in membane towers up to 8 modules (20 m2). The membrane towers can be connected in series or parallel depending on the volume you need to harvest and the end concentration you want to reach.

A LiqoVibro production unit consists of multiple membrane towers and are fully automated. These units will work in a 2-step approach to take the maximum benefit of all membrane capacity. Due to the vibration of the membranes there is minimum fouling and high endconcentrations up to 100-150 grammes per liter can be reached.

 

Liqoflux algae pre-concentration & harvesting systems specially designed for the algae industry

_____

 

We know the challenges in the algae downstream process and the requirements for the pre-concentration and harvesting of algae cultures. The Liqoflux systems, Liqocap & LiqoVibro membranes are specially designed and built for the algae industry. Algae processing is a tough process for membranes. Normally UF filters show initial good performance but after a few weeks/months drop significant in flux and/or increasing fibres breakage. With our membranes we show consistent performance at clients and have a 1 year guarantee on leakage (broken fibers), which is unique in the industry!

 

We selected innovative membranes for the Liqoflux algae pre-concentration & harvesting System

  • The Liqoflux system separates the algae culture into a concentrate containing all the algae cells and clean effluent water, free from algae and bacteria. The clean water is ready for recycling to your algae production system.

  • The innovative membrane properties result in a stable flux and minimal fouling.

  • The smooth structure of the membranes and the well designed flow in the Liqoflux system prevents algae from damaging and keeps the algae-cells fully intact.

  • 100% separation and concentration of the algae biomass, no loss of algae.

The Liqoflux system is a containerized, plug-and-play solution

  • We deliver standard containerized units for processing up to 80 m3/h of algae culture.

  • The operation of the Liqoflux system is fully automatic and PLC controlled.

  • The concentration factor is adjustable to your specific requirements.

  • The Liqoflux dystem is suitable for food-grade and both fresh and marine water applications.

The cost per m3 clean water produced from the algae culture is best in class

  • Due to the low investment costs and low energy requirements you optimize the algae harvesting costs.

  • With the Liqoflux 2-step harvesting approach the investment in harvesting equipment, yearly Capex & Opex and the Total Cost of Ownership (TCO) per kg dry weight algae are reduced by 50-75%

Liqoflux Water recycling system

_____

 

For many algae producers, recycling of the effluent water, after harvesting the algae, is an absolute necessity. It’s our experience that centrifuges do not harvest 100% of the algae biomass. The effluent of the centrifuge contains the ‘lost’ algae cells. The Liqoflux  Water/media recycling system processes the effluent into (1) a concentrate containing all the ‘lost’ algae cells and (2) clean water.

The clean water, free from algae cells and bacteria is ready for recycling to your algae production system. The concentrate can be recycled back to the centrifuge for harvesting. This process harvests 100% of the algae biomass!

 

  • We deliver plug-and-play Water recycling systems, using the right materials for both fresh and marine applications.

  • With the Liqocap® filters and the LiqoVibro membrane modules, specially designed for the Algae industry, we secure the production of clean water.

  • For water recycling we have an integrated Liqoflux algae water recycling system containing: Disk filter unit, Ultra Filtration unit with Liqocap filters or LiqoVibro unit and Advanced Oxidation unit (peroxide + UV)

  • The Liqoflux water recycling system separates the effluent of the harvesting centrifuge into a concentrate containing the (lost) algae cells and clean effluent water, free from algae and bacteria.

  • The clean water is ready for recycling to your algae production system and the concentrate in recycled back to the harvesting centrifuge resulting in 100% separation of the Algae Biomass.

  • The operation of the Liqoflux water recycling system is fully automatic and PLC controlled.

  • The cost per m3 clean water produced from the algae culture is best in class.
