Earth is only known planet in this universe where life is possible only because of the availability of water and oxygen. Water is most important necessity of life for all the living beings on the earth. Without water no one can exist even for a day. We also know that there is very less percentage of clean water means drinking water available on the earth. So, we should not waste clean water and save it for future generations.
We are living in the time when we need to save clean water and use it according to our use only. People at many places in Sri Lanka and other countries are facing a huge water scarcity. They have to depend on the government water supply by tanks or some natural water reservoirs at long distance. They have to go for a long distance on daily basis to arrange drinking water. They better understand the value of water than the people who have sufficient water supply in their areas. The situation of lack of water becomes very terrible for the people who don’t have enough water to fulfill their basic needs of drinking, bathing, washing, etc.So, we should understand the value of water drops and save it.
Major ways of water pollution are Direct incorporation of hazardous pollutants, Disposal of wastes in water from factories and industries, garbage disposal by humans in rivers & etc.
Water clarification polymers are designed to enhance the removal of total suspended solids (TSS), Color, Total Organic Carbon (TOC) and Chemical Oxygen Demand (COD) in turbid water. Low volume of sludge preparing in treatment process with reducing sludge handling cost to achieve environmental compliance goal in water clarification process. the polyacrylamide can be used with several types of chemical and biological water clarifies for high efficiency and improves quality of effluent. This product is designed to enhance liquid-solid separation in a wide variety of industrial applications like clarification, settling, thickening, concentrating, dewatering, flotation and filtration.
Superior flock formation is major effect yielded with limited use of product. Fast settling rate, fast clarification, Use over a broad pH level and easy dewatering quality is effective in various of water purification uses. Combined use with organic coagulant or cross treatment with polymer gives high efficiency to treatment process.
A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. Effective dosage will vary depending on foam origin, stability and the area of defoamer application. Trials are always the best way to determine defoaming capabilities and efficiency.
Water De coloring Agent
Water De coloring Agent is quaternary cationic polymer which is specialized product for De coloring, flocculating, COD decreasing and other application. Water De coloring Agent is widely used for remove color in turbid water from industrial process. treatment to high-color waste water from dyestuff, printing and textile industries waste water . It is suitable to treat waste water with activated, acidic and disperse dyestuff’s.
Water De coloring Agent also can be used in the production process of paper&pulp as retention agent.
Water De coloring Agent should be diluted with 10-40 times water and then dosed into the waste water directly. After being mixed for several minutes, it can be precipitated or air-floated to become clear water; The pH value of the waste water should be adjusted to 7-10 for better result. When the coloring and COD are relatively high, Water De coloring Agent can be used with the help of Poly aluminum chloride, but not mixed together. In this way, the treatment cost can be lowered.
In coagulation, we add a chemical such as alum, Poly aluminum chloride, Ferrous Sulfate, which produces positive charges to neutralize the negative charges on the particles. Then the particles can stick together, forming larger particles which are more easily removed.
Poly Aluminum Chloride (PAC)
Hydrated Lime (Calcium Hydroxide)
