In the paper making factories, one of the great concern is quick flocculation and sediment of waste water. Alum and high polymer are used for the purpose of sediment. The additives are poly ferric sulfate (Ⅲ), Na-PAA, and other organic polymers, and the results were summerized as follows: 1) The low concentration of poly ferric sulfate is effective to form quick flocculation for the waste water of paper making. 2) Curifix. organic high molecular polymer is also efective to the waste water of Korean traditional paper 3) After treated with additives, by agitation of waste water, the formed flocs floated because the specific gravity of floc is smaller than 1. Especcialy Korean traditional paper, the flocs of sludge, floated as soon as the organic polymer added and agitated. 4) When poly aluminium chloride was added to the sludge of J factory, the visible particles were formed as soon as organic polymer, Na-PAA added to it, the floc growth occurred rapidly.

Abelmoschus Manihot medic root extracts plenty of mucilage in water and the viscosity of the mucilage decreases as the time elapses leaving in nature. It was know that the mucilage contained many kinds of amino acids. By using amino acid auto analyzer, the quantity of amino acids in the mucilage were detected and analyzed. Standard amino acids were mixed with the Mucilage, were left in nature and were observed to see biological influence to the standard amino acids. The results were as follows : (1) When the mucilage were left in nature for 1 day, 3 days and 7 days, the quantity of 11 kinds of amino acids in the mucilage were decreased. (2) Standard amino acids-the mucilage mixed solution were detected in every 24 hours by ninhydrin solution. Alanine, L-glutamic acid, glycine, L(-)proline, L-leucine, DL-methionine, DL-serine, DL-threonine, DL-valine, L(+)aspartic acid and L(-)tyrosine, which were detected in the mucilage, were disappeared on the fourth day.

Cellulosic biomass is the most abundant and renewable source which is photosynthesized by solar energy, and the principal ingredient of pulp, agricultural wastes, urban wastes and pulp & papermill factory wastes(sludge) is cellulosic biomass. Thus, in the view of the effective utilization of these cellulosic materials to energy, food and forage, cellulose hydrolysis by acid or enzyme is promising. In this work, the residual sludge of pulp & paper mill factory was hydrolyzed as a renewable source and also for the alternative to pollution control. Sludge can be hydrolyed by conc. H_2SO_4 or HCl. In this case, a large amount of counter-agent is needed while the conversion rate is rather high. That is, the conversion rate was as high as 42% in the case of hydrolysis by72% H_2SO_4 and 30% by 35% HCl. Under the hydrolysis by dil. acid, reaction is terminated in a short time because it is proceeded at high temperature. In our experiments, 18% glucose was produced in an hour at 160℃ by 2% H_2SO_4. The kinetic constant of dil. H_2SO_4 hydrolysis is reduced to express the dependence on acid concentration and temperature. Appling experimental data, the equation is presented with good agrement of 4% error under the temperature of 140∼160℃ and the H_2SO_4 concentration of 0.5∼2%.
