Water Recycling Units

Clean water recycling

The Membracon ceramic filtration systems have been designed to assist for Membrane Bio Reactor (MBR) systems, up to 2,000m3/day, that treat industrial waste water recycling, effluent plants and desalination systems in a multitude of industries; petrochemical, chemical, food & beverage and pharmaceutical.

The benefits of the use of these filtration systems include; a reduction in operational expenditure (OpEx), smaller footprint, minimal operation & maintenance requirements, all aiding in a reduction of disposal costs via reuse.

Membracon not only offers a full, bespoke, design & build for the system to suit each customer’s requirements, but can also provide a comprehensive service & maintenance package along with a tailored financing solution.

A Membrane Bio Reactor (MBR) is a biological waste water treatment process, coupled to a membrane filtration system. The elimination of organic matter, nitrogen and phosphorus is performed through the assimilation by the micro-organisms inside the reactor, while in the membrane an effective separation between the solids (biomass) and the liquid fraction is carried out. As a result, a high quality effluent is produced, free of suspended solids and turbidity and partially disinfected.

MBR systems are characterised by the high quality of the treated water, which fits the requirements for reuse in many cases. Furthermore, the existence of a physical barrier as the membrane, avoids the escape of solids from the biological reactor and the wash out of the biomass. As a result, the efficiency of the process is increased due to the higher biomass concentrations and the footprint is reduced significantly.

MBR filtration systems can be placed inside the bioreactor, in submerged configuration, which allows reducing part of the energetic consumption associated to the filtration.

However, the more extended option in industrial waste waters and small / medium size installations is the external configuration. When the membranes are placed outside the reactor, the operation and maintenance is simplified, and the MBR system can be operated with higher flows in a more stable operation, higher biomass concentration and considerably lower bioreactor volumes. In consequence, we more compact, robust and easy to operate installations can be obtained.

The potential of Membracon ceramic filtration systems, is highlighted when dealing with high-loaded waste water, industrial waters and small / medium flows.

Water recycling membranes

Ceramic membranes are able to provide filtration at high flows, whilst minimising membrane fouling. Furthermore, they have the ability to be regenerated via a much wider range of chemicals, and chemical cleaning conditions than more conventional spiral and hollow fibre membranes.
These membranes are able to resist a variety of solvents, oxidisers and other chemical products across the whole pH range and at temperatures up to 100°C. Because of their material and configurations, they can filter fluids with high concentration of oil, suspended solids and high viscosity. As a result, the membranes are suitable for filtration of any kind of water, liquid wastes, leachate, within the chemical, pharmaceutical, petrochemical and food industries. In general, any type of industrial filtration. Our ceramic membranes are of a high quality and long operating lifetime. Resistant to difficult fluids, and able to operate in a wide range of process conditions.

The key advantages of using ceramic membranes are:

Optimum permeate quality: The high quality of the supports, along with the multiple layer depositions process, allows the appropriate permeate quality, avoiding the appearance of cracks and micro breaks which could contaminate and deteriorate the permeate.

Reliability: Membranes are manufactured following a rigorous quality control, using powders of a controlled granulometry to obtain the maximum homogeneity in the pore size.

Minimum fouling: Thanks to the ceramic material and the latest fabrication techniques, the suitable hydrophilicity degree is achieved, so that the deposition of molecules on the membrane surface and the biofouling processes are reduced, thus minimizing fouling.

Easy regeneration: The ceramic materials used allow aggressive regeneration to take place. Chemical cleaning, with caustic soda, acids, and other specific products at high temperatures are possible. Therefore, severe fouling of the membranes, that has been generated during the filtration process, can be efficiently recovered, extending the membrane lifetime and minimising the maintenance required.
