Technology

Condorchem Envitech provides severalĀ membrane filtrationĀ technologies that enable theĀ production of high-quality waterĀ from various sources of supply. In order to attain water quality goals we design treatment plants with different filtration stages and membrane systems. The type of membrane depends on the particle or ion size that must be removed. The membrane range goes from micro-filtration, ultra-filtration and nano-filtration, and finallyĀ reverse osmosis.

Micro-filtration membranes have a pore size of 0.1-10 Āµm, enough to restrain all types of bacteria, turbidity, macromolecules, colloidals, etc. These are used during cold sterilization of liquid food and pharmaceutical products, water microorganism reduction, water pretreatment for nano-filtration and reverse osmosis, etc.

By means of ultra-filtration, particles with a size of 0.001-0.1 Āµm are removed. All viruses, macroproteins, antibiotics, etc, are restrained in these membranes. These have application in the removal of harmful organic substances from food and drink industries, in the removal of trihalomethanes from water, in the treatment of wastewaters and in the textile industry, amongst others.

By means of nano-filtration, particles with a size of 0.1 nm-0.001 Āµm are restrained, allowing water separation from most molecules, although low molecular weight particles are partially restrained in the membrane. Nano-filtration is used for water-softening, wastewater heavy metal elimination, wastewater decontamination, pretreatment for reverse osmosis, nitrates elimination, colour removal, etc.
