When the subject of Wash Water Recycling comes up there are many questions that can arise. The following are a few that are frequently asked are:

  • Will it have an odor?
  • What will its’ clarity be?
  • How much is recycled?

The above questions seem very basic but can at times create a complex response because of the specific application. Let’s explore each question independently.

Question: Will it have an odor?

Response: The wash water being processed through the GSMS or HSMS Series has no odor because of the micro bubble transfusion taking place inside of the Biological Tank. The transfer of oxygen to the aerobic microbes helps assure the environment stays above 12 mg/L of Dissolved Oxygen so the aerobic microbes can breakdown the organics in the waste stream (ie. oils, greases, etc.).

Question: What will its’ clarity be?

Response: Before answering this question, the term clarity should be scientifically defined as Turbidity. Turbidity is the measure of relative clarity of a liquid and is an indicator of the amount of suspended sediment in the water. A widely used measuring system of Turbidity is Nephelometric Turbidity Units (NTU).

For example, when a grab sample is conducted from a traditional biological wash water treatment system, the water tends to be a “Tea” colored water that grab sample could be 250-450 NTU vs. a grab sample from the GSMS or HSMS System have a 20 – 50 NTU. The difference is the introduction of Clarifloc before entering the Inclined Plate Clarifier of the GSMS or HSMS unit that allows the non-organic suspended solids to drop out prior to entering the Biological Area of the System.

Question: How many gallons of wash water are being recycled?

Response: A key consideration for recycling wash water is the sustainability aspect. The GSMS and HSMS come standard with a Flow Accumulator Meter that digitally illustrates how many gallons have been recycled by the System. This can assist in Corporate Sustainability Reporting (CSR) or determine how many gallons of wash water is being used per day/week/month/year.

As you can see with the introduction of the ESD Waste2Water, Inc GSMS and HSMS Series Recycling Systems, the answers to these questions become have become “clearer”.

Now the only question that begs to be asked is, how can ESD Waste2Water, Inc help you?
