CASE STUDIES
TurboClean® Ultrafiltration Elements – The Highest Protein Rejection
MICRODYN-NADIR is introducing a new line of TurboClean® ultrafiltration membrane elements for whey and milk processing with the highest protein retention and the highest productivity. When combined with NADIR® UP005 membrane, TurboClean UF elements feature the highest protein rejecting membrane with the best sanitary element configuration on the market.
TRISEP® SBNF Cellulose Acetate Elements – NOM Removal for Drinking Water
In Northern Europe, surface water is treated for natural organic matter (NOM) removal, including color removal and TOC reduction, to produce drinking water. The removal of NOM from source waters is very important in drinking water treatment because it affects the color, taste and odor properties of water. A small community in Norway used TRISEP® 8040-SBNF-TSA elements to remove NOM to produce safe drinking water.
TRISEP® Extreme (XT) UF Membranes – Elements for High pH / High Temperature Cleaning
In places where chlorine use is restricted or undesirable due to concerns with chlorinated by-products in wastewater streams, systems are cleaned using alkaline cleaning solutions at high pH and high temperature. We have introduced UF5XT and UF10XT (5 and 10 kDa) membranes primarily of polypropylene materials capable of tolerating these extreme cleaning conditions.
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.
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 BIO-CEL® MBR.
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. BIO-CEL®-MCP MBR process was chosen for its small footprint and low chemical costs.
BIO-CEL® MBR – Municipal Wastewater Treatment Plant
A municipal wastewater treatment plant in Northern Ireland retrofit their existing plant with 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.
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 BIO-CEL® XL MBR modules was chosen, due to its superior performance and low energy demand.
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. 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.
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 BIO-CEL® XL modules. They upgraded their wastewater treatment process and enhanced the effluent water quality for the plant.
BIO-CEL® MBR – Textile Factory Wastewater Treatment
A new generation of BIO-CEL® modules is responsible for the treatment of 1,920 m³/d of wastewater produced from a textile factory in Italy. The aim of the revamping the plant with an MBR system is the recovery of the wastewater for reuse within the production cycle, leading to a maximum annual saving of 30% of the water consumption.
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.
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.
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.
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.
