Reduce Costs with Membrane Filtration for Oily Wastewater Recycling
Posted by Steven Kyle on May 9th, 2017
The burgeoning population has led to a stricter and more scrutinized use of natural resources such as water, to prevent any wastage and ensure its longer availability. Apart from its use in drinking, cleaning, washing and sanitation, water is extensively used in industrial processes that produce a large amount of wastewater. To minimize its wastage, most nations have implemented regulations that bind the industries to implement methods that reduce its use and recycle the used water.
Industrial wastewater recycling is an example of how contaminated water, a byproduct of industrial or commercial activities, can be treated to make it suitable for use again. The treatment covers the mechanisms and processes used to treat the wastewater. The wastewater, generated by the industrial activities, contains a diversity of impurities that the simple purification processes cannot extract. Therefore, its treatment demands a special task that requires an advanced system for effectiveness.
Modern wastewater treatment processes aim to reduce the effluents, such as oil to a bare minimum to protect the aquatic eco-system and initiate potential cost-cutting. Removing oil from the wastewater is the toughest task due to the presence of surfactants such as detergents, cleaners, or additives in oils. To process this, conventional technologies such as coalescers and oil water separators, have been proven impotent. In order to achieve the desired results, one needs advanced oily wastewater recycling systems with enhanced filtration capabilities.
One such oily wastewater recycling system of the modern times is the membrane filtration process that is designed for treating end-of-pipe oily wastewater streams. This industrial wastewater recycling system (WRS) has processing capacity from 50 gallons to over 500,000 gallons per day and can reduce the volume of wastewater to be treated in-house or hauled by 90 to 98%. This is a substantial reduction in the overall cost to the company in wastewater treatment.
It employs a special hydrophilic filter cartridge which is fouling-resistant and thus, produces filtrate that can meet or exceed all government sewer requirements for all grease levels or can be recycled for maximum savings. An example of one such high-tech membrane filtration system is FSI’s WRS that has the ability to withstand widely varying feed changes that can upset most other competitive systems. The importance of using the hydrophilic membrane filtration system lies in its ability to handle high levels of free and emulsified oils.
So, in order to produce positive results and prevent any economic mishaps, using a sophisticated membrane filtration system for industrial wastewater recycling will be a prudent step.
