Sales of centrifuges, clarifiers, dissolved air flotation units and hydrocyclones will exceed $8.5 billion in 2017.  This is the forecast by McIlvaine Company in Sedimentation/Centrifugation World Markets.  (www.mcilvainecompany.com)

East Asia will lead the way with purchases of $3.3 billion. China is installing large numbers of municipal wastewater and municipal drinking water plants.  A decade ago, China’s secondary wastewater treatment capacity was less than 10,000 mgd compared to 38,000 mgd in the U.S. Today, the capacity is more than 30,000 mgd while the U.S. capacity has risen to 40,000 mgd.  However, since China has four times as many citizens, as does the U.S., its treatment capacity per capita is still only 20 percent of that in the U.S.

One of the new developments in China is to bring the product manufacture to the people rather than the people to the product manufacture. Until recently, large manufacturing facilities have been concentrated in large coastal cities. The reason was the easy access to ship transport. This concentration of manufacturing created a large migration of workers from rural areas. The resulting need for drinking water and sewage treatment were substantial.

Recently, the trend has started to shift toward locating new manufacturing facilities in the center and western regions of China. Russia, Kazakhstan and other countries along the rail routes to Europe are upgrading their train tracks and promoting rail shipment.

This new development will reduce the need for treatment facilities in Eastern China and slow the overall wastewater treatment demand.

It is easy to buy the lowest cost product.  It is very challenging to select the best product with the lowest life cycle cost. The buyer has to evaluate supplier claims. This is difficult and made even more difficult in developing countries where there are language problems and lack of experience.

There has been no organized system to help the buyer make the necessary evaluations. In contrast, the buyer can be assured that the supplier will adhere to quality management standards in the manufacture of the product through ISO 9000 and other ISO standards.

Decisive Validation is a process which will make it easy for the buyer to make the best purchasing choices. It involves a whole system with a decisive classification sequence. At each step along the way there is a decisive classification of the options and validation that the supplier product is the right choice.

In addition to the conventional SCR and SNCR, there are three other options presented including ozone injection, hydrogen peroxide injection and the use of a catalytic filter. It is shown that the disadvantages of the chemicals are the operating cost, whereas, the disadvantage of the catalytic filter is lack of experience.

Each application is unique.  In the case of the chemicals, it is necessary to show that in a specific application the cost of the chemicals will be more than offset by the lower capital cost.  In the case of the catalytic filter, there is the need to show that there is ample commercial experience to satisfy the purchaser.

Decisive Validation with independent third party analysis using niche experts is the way to provide convincing evidence.

An additional challenge is to communicate the validation results to the purchaser.  If his native language is Chinese, then the essence of the results along with the decisions sequence need to be provided in Chinese. The Global Decisions Orchard is a mechanism to make these results known.
