Cooling tower is the largest user of water in industrial and commercial applications. Once a rising TDS caused by evaporation reaches a certain level that leads to a critical scaling potential, they are ejected as blowdown from the cooling tower.
Large and small, cooling towers can account for over 90% of the volume of wastewater sent to the sewer system.
3E hollow fibre nanofiltration membranes are highly efficient and yet low cost at removing divalent ions that cause scaling from cooling tower blowdown. It could effectively save water cost for the end-users and minimize environmental pollution impact.
Laundry Water Treatment
Incorporating with ceramic hollow fibre membranes, 3E hollow fibre nanofiltration membranes safeguard the success of laundry water reuse.
3E hollow fibre nanofiltration membranes can directly filtrate hot laundry wastewater after lint removal by a crossflow ceramic hollow fibre membrane process. Hot laundry water reuse could recover both water and energy.
Hollow fibre configuration minimizes the operation cost that further provides cost-saving for endusers.
incorporation of ceramic hollow fibre crossflow process and 3E hollow fibre nanofiltration process makes highest laundry water recovery rate possible.
SWRO has become a dominant process in the seawater desalination market since 2011. The pretreatment process is critical for seawater reverse osmosis.
Most of market available pretreatment processes are only focused on suspended and biological contaminants. In addition to the excellent removal efficiency against the above-mentioned contaminants, 3E hollow fibre nanofiltration membranes could also significantly remove divalent contaminants that are the major factor to cause downstream RO scaling contamination.
Zero Liquid Discharge
ZLD has become a global trend nowadays, more and more industrial players have to conduct ZLD or MLD to meet increasingly stringing regulations required by the governmental authorities.
ZLD is an energy-intensive process. Separating divalent ions from brine prior to evaporation to enhance efficiency and reduce energy consumption is very important to the success of a ZLD process. 3E hollow fibre NF membranes are ideal candidates due to its monovalent-selective property.
