A study was carried out from December 2016 to February 2017 with the aim of evaluating the effects of some coagulants (Aluminium sulphate, Moringa, Starch) on the effluent discharge of the Etoudi slaughterhouse and the Ako’o River which receives these waste products. Monthly water samples surveys were carried out on these two zones and physico-chemical analysis were done following the recommendations of Rodier and his collaborators.

Chemical inducers facilitate broad-spectrum of induced resistance against plant pathogens and thus reduced the toxicity of the chemicals used in excess by the farmers for the management of plant diseases. Banana soft rot incited by Pectobacterium carotovorum subsp. Carotovorum (Pcc) cause huge economical loss to the farming if infected at an early stage. In the present study, chemical inducers viz., salicylic acid, potassium silicate, potassium sulphate, fosetyl aluminium, humic acid @ 1000 ppm and COC 3g/lit + streptocycline 300ppm (check) were tested against Pccunder glass house conditions.

In this paper, we compare coagulation ability of electrochemically activated aluminium colloid, PAC and aluminum sulphate in water purification of Red and Tolich rivers. The examined results shown that activated aluminium colloid is better coagulatant than PAC and aluminium sulfate in releasing Red river turbidity and Tolich river organic pollutants.
