VSEP helps Shanghai automotive factory achieve a 100X reduction in C.O.D.
The wastewater from the production of automotive parts can be difficult to treat due to its varied chemical composition. This type of wastewater contains high levels of COD that need to be reduced to meet local sewer specifications. The typical treatment scheme could consist of chemical treatment followed by a lot of pre-treatment steps and eventually a reverse osmosis membrane system. This type ...

Theoretical and practical experience of calcium phosphate inhibition in RO waters
The increasing trend over the last ten years to use waste water as a feed source for reverse osmosis membrane plant has resulted in an increase in calcium phosphate scaling on membrane surfaces. This is due to much higher levels of phosphate in waste water typically 10-30 mg/l as compared with a groundwater source which may have only 1-5 mg/l of phosphate. These higher phosphate levels resulting ...

HF Pure Water visits the Middle East
HF Pure Water recently participated in the Water, Energy, Technology and Environment Exhibition held in Dubai, UAE. In speaking with numerous people that visited the HF Pure Water booth, it became apparent that there were limited opportunities for waste water treatment as many manufacturers simply dumped their wastewater into the ocean. This was confirmed in a meeting held with the Dubai ...

Contaminants of emerging concern in reverse osmosis brine concentrate from indirect/direct water reuse applications
Water shortage is becoming more common due to droughts and global population increases resulting in the increasing popularity of water reuse to create new water sources. Reverse osmosis (RO) membrane systems are popular in these applications since they can produce drinking water quality effluent. Unfortunately, RO systems have the drawback of generating concentrate streams that contain ...

Municipality of Barrows, Manitoba case study
Situated some 500 km north of Winnipeg, the municipality of Barrows is home to about 300 inhabitants. Barrows has a school in the village with close to 100 students. The only available source of water supply for the municipality is an underground spring with a TDS (total dissolved solids) concentration exceeding 1900 mg/L making the water undrinkable (see Table I). At the request of John Brittain ...

Filter manure slurries directly before, after, or in place of anearobic digesters with a reverse osmosis VSEP membrane system, providing potable water for the animals and a concentrated nutrient feedstock for fertilizer.
If constructed and managed properly, the age-old lagoon method of manure handling is a reliable method of storing and treating livestock waste. Lagoon storage followed by sprayfield application on local farms has proven to be a very symbiotic and effective method throughout the ages. However, the recent trend in the hog production and the cattle industry is towards larger centralized operations ...

Membrane cleaning skids prolong operating life of costly membrane filtration units
Considered one of the most important and costly components of a reverse osmosis purification system, membrane filtration elements (a thin semi-permeable layer which desalinates seawater) collect mineral buildup, organic materials and bacterial agents. The Lifestream Membrane Cleaning Skid cleans, flushes out and preserves the membrane, reviving efficiency and prolonging membrane life.Designing a ...

Membrane contactors are used as a boiler feedwater deaerator
Proper treatment of boiler feedwater is an important part of operating and maintaining a boiler system. As steam is produced, dissolved solids become concentrated and form deposits inside the boiler, leading to poor heat transfer and reduction of boiler efficiency. Dissolved gasses, such as oxygen and carbon dioxide react with metals in the boiler system, resulting in boiler corrosion. These ...

Chlorine removal with KDF 55 - Case Study
KDF 55 Process Medium Helps with Removing Chlorine in a Municipal Water Treatment Facility A Los Angeles-based maker of fashion jeans uses KDF media instead of chemicals for removing chlorine when treating municipal water in their stone-washing process. High-purity copper-zinc redox water filter media consistently provides 99% of free chlorine removal from water by electrochemically reducing ...

Degasification of boiler feed water with Liqui-Cel® membrane contactors
Proper treatment of boiler feed water is an important part of operating and maintaining a boiler system. As steam is produced, dissolved solids become concentrated and form deposits inside the boiler. This leads to poor heat transfer and reduces the efficiency of the boiler. Dissolved gasses such as oxygen and carbon dioxide will react with the metals in the boiler system and lead to boiler ...

Self-Cleaning Pre-Filtration for RO Membrane Systems
ABSTRACT A few years ago physical processes could only remove suspended solids from a water stream. Recent advances in technology now allow the removal of selected molecules and ions from a water stream by physical means using membranes. The membrane process has recently become very efficient and economically feasible for many industrial, commercial, municipal and even residential customers. ...
