Water Use and Reuse in Manufacturing

As supplies of fresh water dwindle, the water need in manufacturing is growing. Can water technologies like desalination and reuse help meet the need?

1. We had a nice presentation on the value of water for manufacturing and tools to assess resuse.  Check it out here... http://www.cobaltwater-global.com/uploads/2/8/2/1/28215105/aiww_2015_porro_et_al.rev2.pdf

2. Mr. Bartley is absolutely right. the key point is the money saving issue. Now, it is known that water are more expensive when they are contaminated because of regulation issues and the need to take special care like treatments before release to the sewage or transporting to authorized sites for farther treatments. in Israel for example water contaminated with heavy metals can cost up to 800$ per cubic meter. The customer is more than happy to pay half the price for water reuse.

    

3. As Mr. Beitler noted, the challenge is to show industry how reuse saves money by reducing their expenses.  In the late 1980's I had a project where we quantified waste cutting oil discharge at a manufacturing plant, estimated recovery and reuse options , and then estimated the savings in reduced cost in the purchase of new oils and reduced permit violations.  By showing the value of reuse in $, the company implemented the plan.  Showing a company how reuse can help their bottom line is the best form of persuasion for a company. 

    

4. Reuse (direct) is the solution for our increasing water demands.

5. WTR tec has developed a technology that is directly facing this problem. The two main ideas are as follow:

   1. A chemical additive free process enable the reuse of the purified water in the original process or otherwise within the industry.

   2. A continuous process enable the very small footprint of the system.

   We are using the technology within the metal coating industry for 4 years with the original water (we need to add from time to time to cover loses in the process due to evaporation mainly). purification process takes contaminated water with Chromium from 3000 ppm to 0-2 ppm. other heavy metals and dyes has the same results.

6. Rainwater Harvesting is very active in the driest of the inhabited continents, Australia.  There is no real reason not to use rainwater in factories, homes and business for non-potable purposes.  In many parts of Australia it is mandatory or semi-mandatory to include rainwater harvesting in all new builds.  Go to the Rainwater Harvesting website: www.rainwaterharvesting.org.au for details of how our country is reducing mains or potable water usage.

7. The reuse of water through out industry and manufacturing will be a major step towards us having enough water. Unfortunately many companies only see it as a cost and not something they need to do but something that everyone else should do. They do not look at the benifits, to them and the world, or what their savings will be, They will not change untill they are forced to by law or their ability to produce things is badly effected by a lack of water.

   This applies to all sizes of corporations and companies.

   Many of the companies producing solutions to the reuse problem are only dealing with the large projects and have forgotton that the number of small users far outweight them.
