The essential challenges of today are to ensure cost effective treatment and recycling processes for water and wastewater. Membrane technology solves this task by being an innovative and trendsetting technology. Today membranes are successfully used for the treatment of municipal and industrial wastewater as well as for the production of drinking and process water from surface water. Membrane technology and membrane bioreactors (MBR) are especially important in arid zones for the recovery of clean water for reuse...
Ceramic membranes are widely applied in a number of industrial water treatment applications. for example as pre-treatment to reverse osmosis or nano filtration. Using our new generation ceramic membranes will enable a durability which provides limited maintenance and an operating life which is expected to exceed 20 years. Moreover, it enables filtration of fluids where organic and other ceramic membrane fall short, such as presence of caustics, solvents, polymers, oxidants and strong acids.
Many wastewater streams contain suspended solids that need to be disposed of or cause problems in ‘downstream’ wastewater treatment systems. Effective TSS removal is an important step to purify water sufficiently for reuse, thereby lowering the requirement for fresh water.
Reverse Osmosis Polishers can concentrate BOD/COD from evaporator condensate and RO permeate streams to reduce waste water. Polished water can also be re-used in plant for boiler water make-up and CIP systems. In Dairy Industry applications, `polishing` of these process water streams aids in the production of Class I water for re-use from dairy products as defined and regulated under Food & Drug Administration rules. Water produced with this technique is also very soft, generally resulting in lower cleaning...
QUA’s CeraQ ceramic membrane modules
are designed for challenging water and
wastewater applications. The CeraQ
modules consist of 3.5 mm ID ceramic tubular
elements potted into bundles for various
surface area requirements. The module is
capable of removing virus, bacteria, colloidal
matter, submicron or micron sized suspended
particles, oil and organics from a wide range
of fluids, including drinking water and
industrial wastewater to economically meet
variety of treatment objectives or to recycle
AQQA® is used in domestic wastewater treatment to: act as barrier for bacteria and virus in membrane bio reactors (directly inserted into the mixed liquor). constitute the final filtration of the effluent of standard sewage treatment plants (tertiary treatment). supply hygienically safe water for reuse, e.g. irrigation of public places and crops. The treated water complies with the German Norm DIN 19650, EK2, reused water for the irrigation of crops for raw consumption. It also exceeds the standards according...
