Abstract The waste water discharge from industry possess a potent threat to the existence of aquatic wildlife, mainly due to presence of high value of COD, TSS, Acidity and Alkalinity. The treatment of such waste water is todays inevitable necessity. Therefore, a more convenient way of treatment considering economic constraints needs to be suggested. This paper delves into the realm of exploiting the impact of new era coagulants on the properties of identified industrial effluent. This paper deals with the review of comparative study of performance of new era coagulants viz. poly aluminium chloride (PAC), aluminium chlorohydrate (ACH), magnesium chloride and poly-glu which can contribute to make primary treatment in a more comprehensive manner.

Keywords Paper mill waste water, Aluminium Chloride (PAC) Aluminium Chlorohydrate (ACH) Poly-glu.

I INTRODUCTION

Now a days, it is very important to treat the industrial waste waters on a serious note. The large amount of

growth in industrial waste waters is to be observed with respect to increasing number of industries. The direct discharge of such industrial waste water into the environment sources create harmful effects to humans, animals and plants. The self-purification capability of the industrial waste waters is less in order to neglect the various pollution problem. The two major sources of adulterated waste water are industrial and domestic waste. Domestic sewage carries approximate 70% of waste water and remaining is carried by industries and other. More effective method is required to treat industrial waste water. In these paper, used new era coagulant for the treatment of paper mill waste water like

  1. Aluminum Chlorohydrate (ACH)

  2. Magnesium Chloride (MgCl2.6H2O)

  3. Poly Aluminum Chloride (PAC) and

  4. Poly-Glu

Supremacy of Magnesium Chloride for Decolourisation

of Textile Wastewater: A Comparative Study on the Use

of Different Coagulants

Decolourisation and COD reduction efficiency of coagulants significantly depends upon the pH of wastewater.

Pre-hydrolysed coagulants such as PACl and ACH were found to be effective in decolourising the wastewaters containing direct and disperse dyes. Further, magnesium

chloride in combination with lime was found to be the best over the other coagulants for decolourisation and CODreduction of textile wastewater containing all the three dyes.

Treatment Of Real Textile Wastewater Using Coagulation Technology

The higher charge density of poly aluminium chloride

Species often results in a decrease in the coagulant dose and the associated solids production. These coagulants have the advantage of being more effective at lower temperatures and a boarder pH range than alum

VI CONCLUSIONS

Summary of the conclusions from the experimental investigations are summarized below.

  • It is low cost method for industrial waste water treatment.

  • The treatment system is eco-friendly.

  • The efficiency of ACH is good than the other coagulant

  • The new era coagulant removed approximate COD (84%), BOD (92%), TSS (87%), and total hardness

    (70%) from the industrial waste water.

  • The overall performance of the new era coagulant is excellent than the conventional coagulant

  • These treatment technology is alternative to conventional treatment.
