Mo et al using flocculation process for the treatment of simulated dyeing wastewater containing PVA, the result showed that adopt Al2(SO4)3 as flocculation when the concentration is 4000ppm (pH=7) or used FeCl3 when it is 1500ppm (pH=10),can removal about ninety percent of pollution material from waste water.It had a greater process in pretreating PVA wastewater with Fenton containing Fe2+ and H2O2.

Optimization of a Reinforcing-Rib Design for ABS and High Glossy Surfaces of Plastic Parts SeongWon Jeong Dept. of Product Design and Manufacturing Engineering, Seoul National University of Science and Technology, South Korea swjeong@seoultech.ac.kr Keywords: Rib, Rib Design, Injection Molding, ABS resin, Response Surface Methodology Abstract.
Material for the Experiment We created a plate-type plastic part [Fig. 1] that was 10 cm in width by 10 cm in length using ABS resin and an injection mold in order to compare the actual amount of shrinkage caused by ribs while varying the condition of the ribs.
The material used to create the mold is CENA1[7], which is generally used to create a mirror-like finish.
This study examined the each effect of variable and the interaction between them within the limit of the ABS material and a high glossy surface.

It should be noted that both Δρbp and τ parameters are not material properties and should depend on the macroscopic growth rate and local temperature, which theoretically should affect the nitrogen pile-up in front of a moving atomic step, since we are dealing here with adsorption-diffusion problem, where diffusion of nitrogen occurs both (1) between the bulk of the gas phase and the growth surface and (2) within the adsorbed layer, away from atomic steps invading terraces and pushing adsorbed nitrogen resulting in the near-step nitrogen pile-up we described in the previous paragraph.

Prediction model of road vehicle noise which could be regarded as discontinuous linear sound was as following: (1) Type: Leqi—equivalent continuous A-weighted sound pressure level of i type vehicle LAi—sound pressure level of i type vehicle radiated noise at reference point; dB T—evaluation time, generally for 1h; Ni —traffic flow of i type vehicle, vehicle / h; Vi —vehicle speed, km/h; ro—distance from reference point to lane; generally for 7.5 meter; r —distance from precalculated position to lane; α—attenuation factor related to absorption characteristics of mulching material, generally for 0.5 in rural area; △S—additional attenuation due to obstructions such as buildings, terrain, embankments, cuttings during noise transmission, dB 2)Equivalent continuous A-weighted sound pressure level of nighttime If the traffic volume of nighttime was less than 300Veh/h, “(2)”should be applied for noise prediction, otherwise, “(1)”used[3]
