The Enviroblast approach to wastewater treatment and filtration

Selecting the correct filtration products for your wastewater treatment needs is critical. Enviroblast ensure a thorough review of your individual site requirements is undertaken prior to recommending the most appropriate solution for your needs. Our process involves determining the following when solving your filtration requirements.

 

1.   Primary Solids

From washing processes there are varying amounts of solids (dirt, sand, silt, clay and even gravel) that are produced. These solids must be collected along with the wastewater in a collection system (pit below ground, or Enviroblast Wash Pad above ground and Solid Settling System above ground model SRS).

2. Secondary Solids

These are the free-floating (suspended) solids that do not readily drop out of the water in a settling tank.  An active solids separation filter is necessary.  Enviroblast provide a unique Continuous Media System (CMS) that acts like a cartridge filter but does not require cartridge changes.

The CMS is provided with a 5-micron nominal filter paper, other micron sizes are available upon request. By reducing fine solids early in the filtration and wastewater treatment process, maintenance is reduced on finer filtration methods used later in the system.

3.   Oils & Grease

If oil or grease is present it must be removed.  Most commonly to less than 50 parts per
million (PPM). Consult your local Trade Waste Department for discharge limitations on oils, grease and hydrocarbons. Free-floating oils can be coalesced and then skimmed.  Enviroblast uses a coalescing plate pack system and an active oil skimming belt system to remove free floating oils.

4. Organics

When you have a high concentration of oils and greases, light hydrocarbons, antifreeze, pesticides, organic nitrogen, soaps and other organics our Bioreactor is the answer. The Biomass inside our Bioreactor increases the surface area for our Bugs to grow and our automatic dosing system allows for precise use of Biological product for maximum digestion of waste and wastewater treatment.

4.  Emulsified Oils & Grease

For emulsified  oils, media filtration is required. Our approach to hydrocarbon removal depends on several things.

• Is the customer using high caustic soaps that emulsify the oils?
• Are you using solvents?
• If the answer is no then coalescing and skimming should be sufficient.

Where heat, chemistry- soaps, solvents or acid are used, oils are emulsified and remain suspended in the water column. It is then more difficult to remove.  Our oil adsorbing media can reduce  hydrocarbons to less than 10-PPM. By making multiple passes through the media, these emulsified oils can be removed.
