• Incensement of total capacity of treatment plant and improvement to water quality can be achieved vary easily. It’s possible due to lamella settlers‚ which provide high treatment in smaller footprint and high degree of settling capacity also process is more efficient and faster than conventional treatment with sedimentation tank. That because of one of most important feature of lamella settlers‚ are series of inclined plate which the suspended particles goes down with water flow‚ where solid particles

AIM: TO MAKE BAKELITE USING PHENOL AND FORMALDEHYDE. INDRODUCTION: WHAT IS BAKELITE? Bakelite or polyoxybenzylmethylenglycolanhydride is an early plastic. It is a thermosetting phenol formaldehyde resin‚ formed from an elimination reaction of phenol with formaldehyde. It was developed by Belgian-born chemist Leo Baekeland in New York in 1907. One of the first plastics made from synthetic components‚ Bakelite was used for its electrical non-conductivity and heat-resistant properties

They filter algae‚ sediment‚ and other pollutants and provide habitat for fish‚ crabs and another organism. In orders words‚ this process decreases turbidity and increase of microorganisms like diatoms and cyanobacteria.

All surface water and some groundwaters require treatment prior to consumption to ensure that they do not represent a health risk to the user. Health risks to consumers from poor quality water can be due to microbiological‚ chemical‚ physical or radioactive contamination. However‚ microbiological contamination is generally the most important to human health as this leads to infectious diseases which affect all populations groups‚ many of which may cause epidemics and can be fatal. Chemical contamination

Expected results in a confirmed case of shigellosis are as follows: Brilliant Green Agar – Isolated Shigella colonies which do not ferment lactose or sucrose and appear red or white in color with no growth to trace growth on the Agar plate will be present. Triple Sugar-Iron Agar – Presence of Shigella will manifest as a red slant with
