As water deficit becomes more and more serious,operation of circulating cooling water system under high cycles of concentration is bound to be the trend.

Preliminary approach to the circulating water concentration multiple increasing of Taxinan Petrochemical Plant;

Measures of raising concentration multiple of the circulating water;

The measures for improving the concentration multiple of the cooling water in cooling tower;

DianodicⅡ neutral water treatment program of GE Company, which is applied in ammonia recirculating cooling water system in Yuntianhua, increased the enrichment factor from 2～3.

By determining the enrichment factor and total yield of Dunaliella salina cells, the effects of different operational conditions, such as gas flow rate (vg), initial cell concentration (C0) and pH on the feasibility of foam flotation of Dunaliella salina cells were investigated.

By determining the enrichment factor and total yield of ginsenosides, the effects of different operational conditions such as gas flow rate, pH, feed concentration and volume, gas type, and operation mode were investigated.

Effective ways to increase the cycles of concentration of circulating cooling water;

Study on the program for the Yellow River water with high cycles of concentration program by dynamic simulation test;

By now,cycles of concentration of this system is 1.

The judgement of scaling thndency in low-pressure operating boiler by using concentrated multiple difference;

The application of concentrated multiple of circulating cooling water in water quality change of supplementary water in Power Plant;
