- One common form of inorganic industrial wastewater comes from automotive maintenance, hydro pads, heavy machinery wash pits and other areas where there is emulsified oil wastewater in the form of natural and synthetic oils. In these cases, the oil must be separated from the water that is to be treated.
- This can be achieved with a Flo Trend Systems Oil Water Separator®. The advantages of using this method of oil and water separation is that this unit does not require a subterranean concrete embankment or need to be set inside of a foundation. The fact that it fits a small footprint and can be moved by a fork lift makes cleaning or removing the oil after use a simple matter.
- As the oily water enters the Oil Water Separator, it is first forced to pass beneath one or more weir (a barrier made of steel plate) that skims a portion of the oil off of the surface.
- The wastewater now flows upward from the bottom of the oil and water separator through the coalescing media (porous tubes) which agitates the wastewater. This causes further separation of oil and water.
- The oil then meets another barrier weir, more than one in some models, that further skims oil from the top as water is allowed to flow beneath.
- After the final weir, water is allowed to flow upward and out of a port that is nearer to the top of the vessel.
INORGANIC INDUSTRIAL OPTIONS & APPLICATIONS
- Leachate Wastewater
- Automotive Maintenance Areas
- Quarry & Mining Wastewater
- Construction Dewatering
- Precious Resource Reclamation and Recycling
The treatment requirements for leachate from landfills depends on the contaminates and discharge requirements. Sanitary Landfill leachate is generally characterized by high total dissolved solids (TDS), heavy metals, high biological oxygen demand (BOD), and/or chemical oxygen demand (COD)– some very refractive– high ammonia, and color. Discharge is often carried out via discharge to a publicly owned treatment works (POTW) where it is mixed/diluted with wastewater.
When diluted with biosolids this wastewater is a prime candidate for dewatering container filters. When undiluted, leachate can be treated through a water treatment system such as the Water Processing Unit®– which replaces traditional reverse osmosis membranes with the more effective and durable ionic filtrate.
Automotive maintenance areas and construction areas often require permitting for their wastewater due to the oil present in the wastewater.
In the cases of automotive maintenance, an Oil Water Separator is required to remove the oil from water using coalescing media to agitate the water and weirs to skim the water off of the top. The Flo Trend Systems Oil Water Separator® is an above ground unit that can therefore be easily cleaned and maintained.
Roll-Off Container Filters and Self Dumping Hoppers® have the convenience necessary in many mine and quarry situations. They do not require the manpower and time it takes to reuse a geotube or dig an excavated barrier. At the same time, they can be simply moved around by forklift.
In the case of construction maintenance wastewater is commonly the result of wash pits or hydro-pads which are used to collect the water used to clean off heavy equipment. This water, depending on its content can be sent through dewatering container filters, an oil water separator, or can be reclaimed and re-used using a Water Processing Unit.
Dewatering container filters such as Self Dumping Hoppers® and Front, Rear, or Side Loading Container Filters are often used in existing industrial processes to reclaim valuable or precious resources from a stream to be reused in the process. The popularity of these smaller container filters is largely due to their small footprint, the ability to fit them into the tight quarters of an existing process/facility, and the fact that they can be moved by forklift.
