Maxie focus on water filtration ranging from home drinking water multi-stage filtration to emergency water filtration for field operations.
We offer a broad portfolio of globally recognized, industry-leading solutions to help you produce, purify, and extract some of the world’s most commercially important products.
As with most conventional filtration methods, sand filters and media filtration require consistent raw water quality to deliver quality effluent, which is not always possible. They also don't provide an absolute barrier. Traditional media filters typically remove particles to down to about 5 microns.
Ultrafiltration (UF)membrane, however, does not suffer from those limitations. This technology uses an ultrafiltration membrane barrier to exclude particles 0.02 to 0.5 microns, including bacteria, viruses, colloids, micro organisms such as cryptosporidium and giardia, as well as silt, turbidity. Meeting increasingly stringent water-quality standards around the world, and providing a stable, reliable, and consistent water quality.
When used as a pretreatment for reverse osmosis (RO) , UF also helps reduce fouling of the RO membranes, which can lead to:
High and consistent product quality measured by turbidity (NTU) or silt density index (SDI).
Tolerance to feedwater quality upsets.
No use of pretreatment chemicals (polymer, coagulant, pH adjustment) and associated costs for sludge disposal.
Small footprint and less weight than media filters.
Ultrafiltration (UF) is a membrane filtration process similar to Reverse Osmosis, using hydrostatic pressure to force water through a semi-permeable membrane element. In this method we use Maxie hollow fibers.
UF is a barrier to suspended solids, bacteria, viruses, endotoxins, and other pathogens. UF produce water with very high purity and low SDI.
A pressure is the driving force for the membrane. The pressure allows the water to flow through the pores of the membrane. All matter larger than the pores is retained on the surface of the membrane. This process is called pore size exclusion. The membrane is called semi-permeability because it allows water to pass while it retains other substances. The pore size of the membrane determines the size of the particles that are being removed. If the pores are micrometer sized the membrane is called a microfiltration membrane, if the pores are smaller than a tenth of a micrometer the membrane us called an ultrafiltration membrane.
Microfiltration and Ultrafiltration membrane elements are capable of removing suspended solids, bacteria and larger micro organisms, such as cryptosporidium and giardia. Additionally the ultrafiltration pore size is small enough to reliably remove smaller matter such as viruses, macro molecules and colloidal matter. Dissolved matter, such as e.g. beneficial minerals are not being retained by the membrane elements.
Simple process and compact plant
Good and constant quality of the treated water concerning microbial and particle removal
Friendly for the environment and energy
Very low consumption of chemicals
Water from a variety of sources, such as ground water, lake water, river water or seawater can be sources for drinkable water treatment.
Meeting the global drinking water quality standards requires a wide local variety of treatment methods, due to different feedwater sources. Maxie delivers solutions for every drinking water application.
Ultrafiltration is the perfect method for producing drinking water from surface water.
In some cases, bore holes for collection of ground water that were constructed many decades ago are constructed of bricks. When exposed to ground movement, cracks can develop which allows surface water to enter the bore holes.
The traditionally clean ground water can then become contaminated with microbes. This is referred to as “ground water under the influence of surface water”.
The Maxie membrane solutions can be used to filter the ground water to remove contaminants and guarantee complete removal of bacteria and viruses. Surface water contains microbiology as well as suspended solids. Sometimes dissolved organics are present that cause color in the surface water. Maxie membranes solutions can provide a reliable treatment system that eliminates the need for multiple treatment steps.
