Continuous Improvement Evolution

A Primary Mission of the Council is to promote effective means of surface preparation in the maintenance industry using water and water/abrasive blasting techniques.

We will examine how this continual improvement evolution came about and what the change means to the marine construction industry in terms of waste minimization and pollution prevention.

We will look at the volumes of water produced by waterjetting compared to storm water run-off.

You have to make the decision whether this is just for the effluent water from the jetting or if it will include the storm water runoff also.

Let’s estimate conservatively that the contractor will run 2 UHP Waterjetting pumps for 16 hours non-stop.

One of the major costs involved in a treatment system is how low the discharge contaminate numbers are that must be met.

After determining how much water will be generated and what you plan to do with it after treatment, you can look at the treatment system.

The wastewater is drawn from the holding tank at the prescribed flow rate determined and sent to a retention tank with constant agitation.

For more difficult applications it typically would pass though a gravity sand filter to capture any extremely fine particles.

3. Design a treatment system that is big enough to treat the amount of waste water you will generate, and be sure its design will remove all contaminates you need to have removed for discharge.

It is possible to run a UHP WJ unit with vacuum recovery on only 50 gallons a day.
