Red mud is the industrial solid waste from Bayer's process to manufacturing of aluminum oxide. It is also called bauxite residue .Approximaly 95%of red mud is produced from the Bayer's process. However, the accumulation of red mud is a big concern of recent time due to significant toxicological impact on the environment .On most research done, foun...

The first order plus time delay (FOPTD) model was assumed and the improved relay tuning method was applied for tuning with higher order of relay harmonics. A relay feedback test was conducted to obtain a symmetric relay response and ultimate gain. Then Ziegler-Nichols optimum controller parameter method was applied for estimation of optimum control...

The first order plus time delay (FOPTD) model was considered and the improved relay tuning method considering higher order of harmonics (N) was applied for tuning to calculate the corrected ultimate gain (Ku). This corrected value was used to estimate PID parameters by Ziegler-Nichols (ZN) method. Then these PID parameters were considered for Taguc...

The mining industry faces stringent effluent discharge regulations and has acknowledged that it is necessary to look into innovative technologies to recycle considerable amount of effluent rather than discharging into surface water. Effluents from mines give rise to aesthetic unpleasantness. The focus of the investigations was to cope with more str...

The liquid level control unit approximated by the first order plus time delay (FOPTD) model was considered and the proposed modified relay tuning method was applied to calculate the corrected ultimate gain (Ku). The proposed method includes the correction factor in equation for calculation of ultimate gain (Ku). The effect of ratio of time delay to...

Removal of auramine dye from aqueous waste solutions was investigated by using very cheap and biosorbent, withered guava tree leaves and activated carbon. Guava leaves are readily available in the western and northern parts of India throughout the year, and hence form a cost effective alternative for removal of dyes from waste waters. The optimum c...

The removal of copper from acid mine drainage waste by ion exchange resins, such as Indion 820 and Indion 850, is investigated. Effect of initial metal ion concentration, resin dose and pH on exchange capacities of ion exchange resins was studied in a batch method. The adsorption process, which is pH dependent, shows maximum removal of copper in th...
