PRODUCTS- WASTE WATER |
|

WASTEWATER TREATMENT AND REUSE THROUGH MEMBRANE BIO-REACTOR (MBR):
CWS can design, build and operate submerged or external MBR plants to suit your needs.
The advantages of the process are multiple:
• 50% smaller footprint and up to 35% reduction in capital cost than a conventional tertiary treatment plant ;
• Energy savings due to the absence of requirement for aeration lagoons, clarifier, sand filter and disinfection;
• Lower waste disposal cost due to a reduction in sludge production;
• Cost effective retrofit for existing facilities;
• Record Low energy consumption (~1.33 kWh/m³ of clean water produced);
• Low maintenance costs.
To meet your water quality requirements, the MBR system will be followed by the addition of a supplementary treatment stage (nano-filtration, Ozone or Granulated Activated Carbon etc.). Each plant is taylored to your needs ! |

SUBMERGED MEMBRANE BIO-REACTORS
Submerged Membrane Bio-Reactor Technology is a sound technical approach for producing high quality effluent from wastewater.
This technology offers a compact built purification system combining the biological degradation step with a membrane separation step. This combination offers several significant advantages over a conventional activated sludge system, such as a higher biomass concentration and less sludge carry-over |
The higher biomass concentration results in a more compact system. . The decrease in sludge carry-over reduces the need of post-treatment if the effluent.
This technology allows an increase in the concentration of the sludge (Bio-Reactor) and enables the production of high quality effluents (Membrane Filtration), free of suspended solids, most pathogen bacteria (including cryptosporidium and Giardia Cyst). This offers a reliable new water source for various beneficial uses, from relatively simple agricultural irrigation, to the recycling of industrial process water, to complex potable water reuse. |
PRODUCTS- DESALINATION |
|
|
SEA WATER REVERSE OSMOSIS (SWRO) PLANTS:
CWS specialise in low-energy consumption (2.40 kWh/m³) desalination plants with capacities ranging from 100m³/day to 50,000m³/day as follows:
100m³/d to 6,000m³/d: Our plants, including pre-treatment, post treatment and clean in place facilities are assembled in 20 feet and 40 feet ISO Reefer Containers. |
Beyond 6,000m³/d: Our plants need to be built on-site and civil engineering works are required.
Our containerised plants are built in our facility in Marseille, France. Each plant is thoroughly tested prior to the shipping to its final destination. This allows delivering a "ready to plug" solution where and when it is needed. |
The 5 main benefits for our customers are as follows: |
• No need for expensive and time-consuming civil engineering costs (Containerised solutions);
• Minimal disturbance during the installation of our containerised plants - A simple concrete slab would be required to unload and support our treatment plant;
• An economic treatment plant ready to produce - all what is required on our client's part is to arrange for seawater intake and electrical supply;
• Our 18 inch membranes offer extreme compactness and high production yield from each element of 260 m² surface area, compared to standard 8 inch membranes with only 37 m² surface area;
• High efficiency salt removal rate with our membrane (99.6%). |

PRODUCTS - ULTRA FILTRATION |
| |
|
ULTRAFILTRATION PLANTS
Ultrafiltration is used to treat surface water, groundwater and wastewater as either a primary treatment or as a pretreatment to nanofiltration and/or reverse osmosis.
Membrane filtration offers many advantages over conventional water treatment by sedimentation and sand filtration, notably. |
The technology used by CWS replaces conventional pretreatments for potable applications, groundwater recharging and water recycling. The main benefits of our plants are as follows:
The cut out range of our membranes is 0.015 μm. This provides the ability to efficiently and reliably achieve high rates of removal of pathogenic microorganisms such as Giardia and Cryptosporidium as well as most viruses;
• Each membrane covers a surface area of 46 m² which is equivalent to the production of 60 m³/d of potable water.
• Our ultrafiltration plants can be containerised and can accommodate production rates of up to 3,000m³/d per 40feet containers;
• This technology only requires low pressure water feed (2 bar), which equates to very low consumption cost of €0.03/m³. |
PRODUCTS – BALLAST WATER |
|
BALLAST WATER TREATMENT SYSTEM
The International Convention for the Control and Management of Ships' Ballast Water and Sediments, 2004, mandates that all ships that carry ballast water install a treatment system by the year 2016. Ratification and implementation of the United Nations' International Maritime Organization (IMO) ballast water management convention will soon make it a criminal act to discharge untreated ballast water. |
From the date of implementation (2009), ships will be required to treat ballast water discharge to achieve less than 100cfu/100mL of Enterococci and less than 250cfu/100mL of Escherichia Coli. Vibrio Cholerae (O1, O139) should be less than 1cfu/100mL or less than 1cfu/g of zooplankton samples.
Benefitting from the legacy of Hydrotech France and over 20 years of experience in designing water treatment solutions for the maritime industry, Concorde Water Supplies (CWS) have developed a system that meets the stringent requirements put forward in the 2004 convention. Our system consists of solid separation (filter) followed by UV irradiation:
•The screening filter is designed to remove organic matter to meet D-2 standard and;
•The High Power UV system is aimed at inactivating marine organisms, viruses and bacteria, without affecting the normal operation of the ship.
Ballast water is treated both during ballasting and de-ballasting to ensure the dual effect. All of our water ballast systems are developed and manufactured for installations aboard ships and tailored to your needs. For retrofit purposes, they can be delivered in containers allowing easy installation on deck or other available spaces. In addition, our systems allow:
•Small adaptable to requested flow rates - 50 m³/h - 7000 m³/h;
•High screening efficiency;
•Fully automatic self-cleaning system, efficiently handles heavy dirt load in raw water;
•Low operating pressures meet parameters of existing ballast water pumps;
•Uninterrupted filtered water supply during flushing;
•Long service life due to anti-corrosion protection coating and stainless steel screen;
•Low running and low maintenance cost. |
WHY CHOOSE US |
You want to reduce your water bill, intend to build a new (waste)water treatment plant or need to upgrade your existing plant.
No matter what your need, with over 37 years of combined experience, we can help you solve any water treatment related challenges you may have.
EXISTING TREATMENT PLANT
We can retrofit our own technology, thus ensuring that you meet the existing and future standards. This will help you to:
•Reuse your existing plant;
•Make the best use of the space you have available;
•Avoid the building costs a new plant would incur - thanks to cost effective modifications of existing facilities to meet increasingly more stringent requirements for effluent discharge permits;
•Produce water of such good quality that it can be reused in your production processes – itself leading to ongoing savings by reducing water rates.
NEW TREATMENT PLANT
We can assist you with your planning application (abstraction licence or discharge licence) and provide a Design-Build-Operate service. In this way, we can:
•• Substantially reduce construction costs in comparison to a conventional wastewater treatment plant;
•• Design, build and operate (if necessary) a plant tailored to your needs with scalability for growth (if requested);
•• Produce water of such good quality that it can be reused in your production processes leading to ongoing savings by reducing water rates |
