Four tests were performed simulating break sizes of –2% (approximately corresponding to –40 0 breaks for a referenced nuclear power plant) at coldleg for .
Final report on desilication of black liquor in Turkey (reference: pulp and paper industry) covers (1) the role of silicon dioxide in pulping and chemical recovery cycle (2) need for desilication; methods (3) desilication using semipilot submerse reactors (4) proposed desilication factory (5) inplant training.
The soluble silica is the silica absorbed by the plant in its growth and is sometimes found inlocalized concentration in the plant, for example, in the nodes of the bamboo plant. ... may be employed for desilication of pulp liquor despite the colorant ( ) present in the bauxite. ... Black Liquorliquor comprising organics ...

The supernatant liquor above the residue was normally returned to the plant for reuse thereby recovering some of the caustic soda value and avoiding contaminating the environment. Various drainage and seepage collection systems have been incorporated into the design and construction of the facilities.
Flotation tests In these tests, the coal samples were prewetted in a flotation cell for 3 min at the impeller speed of 1910 rpm. After the prewetting process, the collector was added into the flotation pulp, and the pulp was conditioned for 3 min.
Tests were conducted at small laboratory scale followed by a larger proof of concept demonstration in a plant environment. The results confirmed the process performance and viability of the new technology.

Therefore, desilication of the black liquor is necessary before sending the liquor to the evaporators. Several experiments and designs have been proposed for desilication. A pilot plant .
Objectives The successful materialization of the concept of microbial desilication demands the isolation of novel strains of microorganisms, capable of desilication and the improvement of their activities either through process optimization or through introduction of modifications at the molecular 3 level.
