The methods of water treatment include physical treatment, chemical treatment, and biological treatment.
Physical methods include using various filter materials with different pore sizes, using adsorption or barrier methods to remove impurities from water. The most important adsorption method is to use activated carbon for adsorption, and the barrier method is to pass water through the filter material, preventing larger impurities from passing through, thereby obtaining cleaner water.
Industrial Water Treatment Process
Raw water → Raw water tank → Raw water pump → Multi medium filter (quartz sand filter) → Activated carbon filter → Precision filter → High pressure pump → Primary reverse osmosis (RO) device → Purified water tank → Water point
Precision filters (also known as security filters) are generally made of stainless steel for the cylinder shell, and use tubular filter elements such as PP melt blown, wire burned, folded, titanium filter element, activated carbon filter element, etc. as filter elements inside. Different filter elements are selected according to different filter media and design processes to meet the requirements of effluent quality.
The Falling Film Evaporator, particularly well suited for temperature-sensitive products, liquids containing small quantities of solids and with a low to moderate tendency to form incrustations.
The main components of the reverse osmosis pure water equipment are imported composite membrane elements and imported high-pressure stainless steel pumps. Compared with other reverse osmosis elements, it has unique advantages in terms of water inlet adaptability, desalination rate, and service life;
It is an efficient filtration device that uses quartz sand as a filtering medium to filter water with high turbidity through a certain thickness of granular or non granular quartz sand under a certain pressure, effectively intercepting and removing suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors, and some heavy metal ions in the water, ultimately achieving the effect of reducing water turbidity and purifying water quality.
The cylinder body of the activated carbon adsorption filter adopts a hydraulic simulation long diameter design and uses high-efficiency activated carbon with a reasonable particle size and a specific surface area greater than 1000 ㎡/g, which has both upper layer special filtration and lower layer efficient adsorption functions, greatly improving the degree of water purification and the service life of carbon.
•After treatment by the activated carbon adsorption filter, the residual chlorine content of the water quality is ≤ 0.1PPM.
•It has outstanding performance in dealing with odors, organic matter, colloids, iron, and residual chlorine in the water;
•It also has a good effect on reducing turbidity and chromaticity of water bodies, purifying water quality, and reducing pollution to subsequent systems (reverse osmosis, ultrafiltration, ion exchangers).
