Latest membrane technology is the core of our products and services.
The principle of membrane filtration is physical separation. The extent which suspended solids, turbidity and microorganisms are removed is determined by the size of the pores in the membranes. Substances that are larger than the pores are fully removed. Other separation forces also play a role in membrane filtration.
Our filtration includes:
Ultra-filtration is a pressure-dependent membrane process, which removes dirt, solids and non-soluble substances from water resources.
We use a hollow fibre proprietary polymer, high density PAN, PTFE (Teflon) and PVDF membranes, to filter down the dirt, solids, and non-soluble substances to 0.02 micrometers. As a result, the water becomes crystal clear and is 1,000 times cleaner than traditional sand filtered water at a similar cost.
Ceramic membrane is used due to its superb physical properties and chemical resilience, making it a robust system for many kind of industrial wastewater and in submerged Membrane Bio Reactors.
For Nano Filtration and Low Pressure Reverse Osmosis we use a proprietary hollow fibre or spiral wound polyamide membrane to remove dissolved matter, color, taste, salt, hardness and metal ions.
Our engineers will recommend the ideal “cut” for individual cases to optimize energy cost and investment.
Reverse Osmosis (RO) is a filtration method that removes many types of molecules and ions from solutions by applying pressure on one side of a selective membrane, retaining the solute on the pressurized size of the membrane and pure solvent (mainly water) is allowed to pass to the other side.
Reverse Osmosis is most commonly known for its use in drinking water purification from seawater, removing salts and other substances from water. This is the reverse of the normal osmosis process, in which the solvent naturally moves from an area of low solute concentration, through a membrane to an area of high solute concentration.
The predominant removal mechanism in membrane filtration is straining, or size exclusion, so the process can theoretically achieve perfect exclusion of particles regardless of operational parameters such as pressure and concentration. Reverse osmosis, however, involves a diffusion mechanism so the separation efficiency is dependent on solute concentration, pressure and water flux rate.
We apply the latest energy recovery systems and pretreatment in our process to produce environmental friendly and cost-effective water for our clients.
This is a combination of high rate anaerobic and aerobic bio-process with membrane filtration to drastically reduce retention time and footprint, and to improve effluent water quality for recycling or disposal.
