Filtration Systems Enable Industrial Wastewater Reuse

While reusing industrial wastewater has lately been a topic of growing consideration, the UN put this issue front and center with its 2030 Agenda for Sustainable Development which calls for a reduction by half in the amount of untreated industrial wastewater in the world by 2030.

In tandem with this effort, several movements in the states have pushed the conversation even further, namely the Clean Water Act, the Resource Conservation and Recovery Act, and the Safe Drinking Water Act. The momentum towards cleaner industrial wastewater has significant implications for the quality of our drinking water since a majority of wastewater flows into streams, rivers, and groundwater sources for human consumption.

Filtration systems that specifically target industrial wastewater have made water suitable for reuse, and it has reduced the number of pollutants that flow into drinkable water sources.

Water Is A Precious Resource

In many parts of the world, water is a finite resource. Industrial plants in these regions can lighten the toll its water consumption takes on this scarce resource by reusing the water it uses in its processes.

Reducing Environmental Impact

Using a filtration system on industrial wastewater can make it adequate for reuse by the same industrial plant. At the very least, it will remove common industrial pollutants such as harmful chemicals used in the production of goods so that these chemicals don’t seep into familiar water sources such as groundwater, streams, rivers, and lakes.

Disposing Of Wastewater Is Becoming More Expensive

Costs to dispose of wastewater are on the rise in the face of increasing environmental regulation. Factors to consider when comparing the upfront cost of wastewater reuse and recycle system versus wastewater disposal and source water replacement include transportation costs, local water resources, fuel costs, and treatment facility stipulations.

Companies Are Improving Their Image

Industrial complexes easily earn bad reputations quickly. Although they are job providers, many local communities would choose not to have them in their area. One way to combat this negative perception is by taking responsibility for their environmental impact by employing a wastewater filtration system.

Types Of Filtration Systems

  1. Vacuum Evaporation

Evaporation works by causing water to evaporate away from the contaminants in it. The evaporated water is achieved via heat pumps, using excess hot water from the plant, or through mechanical vapor recompression for substantial wastewater treatment.

  1. Paper Bed Filtration

An efficient way to remove some metals, glass, rubber, plastic and other contaminants, paper bed filtration uses the process of free flowing water through a permanent or disposable paper membrane.

  1. UltraFiltration Systems

UltraFiltration (UF) is a highly efficient and cost-effective way to treat industrial wastewater. UF is highly effective thanks to the versatility in the type of contaminants it removes. UF filtration uses pressure to trap contaminants such as oil, metals, suspended solids, bacteria, soaps, etc. behind membranes. UF is a chemical-free way of significantly reducing the amount of wastewater a plant manufacturer.

  1. Reverse Osmosis

A common filtration method used in both industrial wastewater recycling and consumer consumption is Reverse Osmosis (RO). RO a process whereby water is pushed in the opposite direction from its tendency to flow from an area of less concentration to an area of more concentration. Instead, water is forced from an area of more concentration (in this case contaminant concentration) through a membrane to an area where the contaminants do not exist.

RO systems are effective at moving the vast majority of salts, impurities, suspended matter, metals, etc.

  1. Oil Separators

When oil is the primary culprit comprising industrial wastewater, a tramp oil separator is a safe bet for getting the water oil-free again. It uses the power of gravity and filter beds to separate oils and other debris from the water. The water flows into a container to prepare for reuse, and the trapped oil is collected and properly disposed of into a receptacle.

  1. Solid Bowl Centrifuges

An efficient way to separate solids from liquids, particularly metals, is by using the power of centrifugal force and gravity. Contaminated water enters a centrifuge and flows in this motion down via gravity.  As the water flows, it separates from metals and other solids that collect in a removable rotor.

  1. Vacuum Filters

Vacuum Filters can run endlessly, making it a particularly efficient form of water decontamination. Water is drawn through a paper filter into a separate chamber via a vacuum. The separated water is now ready for reuse, and the contaminants that have built up on the filter are removed via back-flushing.

Whatever method a particular industrial site chooses for their wastewater cleanup, the value of doing will demonstrate itself in the improved environmental health of the area, the ultimate lower clean up costs for the operation, the positive image portrayed by the organization, and the increased protection of valuable water resources.
