Issue 12/2019 - Advanced membrane modules improve water treatment efficiency

DuPont Water Treatment
, part of DuPont's Safety & Building Division, unveiled several new solutions
at the 2019 Shanghai International Water Treatment Exhibition.

^DuPontTM special membrane XUS290904 wide flow nanofiltration membrane element adopts HYPERSHELL^{TM reverse} osmosis technology, using a machined polypropylene steel shell, which not only saves energy, improves the efficiency of water treatment and chemical cleaning, but also improves the safety of the system, makes loading and unloading faster, and ensures the lowest failure rate of the membrane module during its lifetime; All materials comply with FDA regulations
for contact with food.
The unique design is particularly suitable for demanding process conditions and process handling
.

FILMTEC^TMTW30-3012-600HR high-flow household reverse osmosis membrane element adopts low-pressure drive to provide sufficient power; Reduce wastewater discharge by up to 50%; Excellent water quality and fast high desalination rate
.

The MABR membrane aeration biofilm reactor uses "embedded" technology to significantly improve drainage quality and biological treatment capacity, save energy by 75%, and reduce sludge yield by 50%.

In addition, the reactor can be installed without stopping the operation of the existing wastewater treatment system, nor does it require additional land occupation and additional infrastructure
