TRISEP® SBNF醋酸纤维素膜组件 – 饮用水的NOM去除
在北欧，地表水经过天然有机物（NOM）去除处理，包括去除颜色和减少TOC, 以生产饮用水。从源水中去除NOM在饮用水处理中非常重要, 因为它会影响水的颜色、口感和气味特性。挪威的一个小社区使用TRISEP® 8040-SBNF-TSA膜组件去除NOM以生产安全的饮用水。
TRISEP®（XT）UF膜组件 – 用于高pH /高温清洗的膜组件
在一些情况下，考虑到使用氯会导致废水中残留氯副产物，就采用在高pH高温下使用碱性清洗溶液对系统进行清洗。我们推出的主要由聚丙烯材料制成的UF5XT和UF10XT（5和10 kDa）膜，能够耐受这些极端的清洁条件。
TRISEP® X-20™ Low-Fouling RO – Wastewater Treatment Plant
A large municipal wastewater treatment plant in Spain constructed a tertiary treatment facility for irrigation reuse, including an RO system. The RO system was installed using TRISEP® X-20™ membrane elements to convert high-fouling wastewater to high-quality irrigation water with long element life. The tertiary treatment plant, including robust desalination with X-20 membrane, continues to provide the region with high quality water for re-use.
TRISEP® X-20™ Low-Fouling RO – Oil Refinery
A leading oil refinery in Southeast Spain chose TRISEP® X-20™ RO membrane elements to treat high-fouling wastewater from boiler water production plant. X-20 membrane elements were selected for this system because they showed the best combination of high salt rejection and continuous high permeate flow for the duration of the study, with the least decline in permeate flow over time on the high-fouling feed water.
Diminishing fresh water availability in the face of increasing population and agricultural demands has been a persistent concern for communities in Spain. TRISEP® X-20™ Low-Fouling RO Elements were selected by a major municipality in Valencia, Spain to treat municipal wastewater for reuse. The original set of X-20 elements have provided consistent permeate flow and quality for over 11 years.
MICRODYN BIO-CEL® MBR – Removal of Micropollutants
Micropollutants such as antibiotics, X-ray contrast media, hormones, pesticides, and microplastics occur in wastewater in the nano- to microgram range. Conventional wastewater treatment plants cannot remove micropollutants sufficiently without an additional treatment step, such as activated carbon in combination with MICRODYN BIO-CEL® MBR.
MICRODYN BIO-CEL®-MCP MBR – Tuna Wastewater Treatment Plant
Located in Mazatlán, Mexico, a tuna cannery needed to update their wastewater treatment plant (WWTP) to comply with new regulations. MICRODYN BIO-CEL®-MCP MBR process was chosen for its small footprint and low chemical costs.
MICRODYN BIO-CEL® MBR – Municipal Wastewater Treatment Plant
A municipal wastewater treatment plant in Northern Ireland retrofit their existing plant with MICRODYN BIO-CEL® L-1 modules while keeping the plant operational. The discharge limit for BOD and suspended solids is very strict as this site is located near a popular beach.
MICRODYN BIO-CEL® MBR – Wastewater Treatment for Irrigation – Israel
Located in HaSolelim, Israel, a municipal wastewater treatment plant updated its MBR plant. The purpose of the plant is to provide high quality effluent for irrigation purposes. An MBR system using 6 MICRODYN BIO-CEL® XL MBR modules was chosen, due to its superior performance and low energy demand.
MICRODYN BIO-CEL®-MCP MBR – Wastewater Treatment for Irrigation – Turkey
A municipal wastewater treatment plant in the Konacik district of Bodrum, Turkey, sought to upgrade their existing MBR plant, where the effluent is used for irrigation. MICRODYN BIO-CEL® 400 modules were selected for the project. Since the project’s completion, plant performance has been stable and is reliably producing high-quality effluent suitable for irrigation.
MICRODYN BIO-CEL® MBR – Petroleum Refining Wastewater Treatment
Due to insufficient performance, a petroleum refining wastewater treatment plant in Shandong Province, China, reconstructed and changed to an MBR solution using MICRODYN BIO-CEL® XL modules. They upgraded their wastewater treatment process and enhanced the effluent water quality for the plant.
MICRODYN iSep™ 500 UF Modules – Produced Water Treatment
In light of ongoing fresh water shortages and stricter discharge regulations, oil & gas producers have taken on new sustainability goals that place greater emphasis on water conservation and reuse. The high oil and solids tolerance of iSep membranes enables oil & gas producers to reuse produced and flow back waters, preserving valuable fresh water resources while reducing disposal costs.
MICRODYN iSep™ 500 UF Modules – Treatment of Coal Fines Water from a Power Plant
A coal-fired power plant in the Midwest conducted an ultrafiltration (UF) pilot study on river water to qualify an alternative source for their boiler water make-up. After the successful river water pilot study, the power plant tested the feasibility of iSep UF modules to treat their ash pond water.
MICRODYN iSep™ 500 UF Modules – High Turbidity River Water Filtration
Rivers and surface waters provide a convenient and reliable water source for both municipal and industrial waters. However, rainfall and seasonal changes may affect microbial activity, organic loading and turbidity spikes, posing a problem for most treatment technologies.
MICRODYN iSep™ 500 UF Modules – MBR Peak Flow Management
Membrane bioreactors (MBRs) are often used in municipal wastewater treatment plants (WWTP) that experience high, transient peak flows. Since MBRs are generally designed to handle peak flows only twice that of the average daily flow rating, a peak flow management process using ultrafiltration modules was developed to operate in conjunction with MBR systems.
Ox Mountain Landfill is a Sanitary Waste Disposal Facility in Half Moon Bay, California and processes landfill-impacted groundwater. The state-regulated total suspended solids (TSS) limit for the Groundwater Treatment System (GWTS) is 27 mg/L, which is difficult to achieve in a sedimentation basin. Instead, InviroTreat Inc., the design engineer for the GWTS, proposed a low-footprint ultrafiltration system to remove the iron-hydroxide solids.
