Brief introduction
Suspended matter in swimming pools is generally soluble, but many of its surfaces are charged (ZETA potential), which makes it very stable in water and cannot be settled. After adding the flocculant, the flocculant with the opposite charge of the material can be compressed, neutralize the potential of the suspended material, so that it loses its stability, collide and fuse with each other, thus settling. Some flocculants can directly adsorb suspended substances, and polymer flocculants can also directly bridge the small suspended particles together.
Swimming pool water treatment involves a lot of work and steps to keep the swimming pool water hygiene and clean, the need to remove algae and algae suppression work on the pool water, the need to add swimming pool disinfectant, the need to circulate the filtration system to filter the pool debris every day, and, the need to use the pool suction machine for the pool suction dirt. In the process of swimming pool water treatment, the circulation filtration system can not filter out the tiny particles in the pool, at this time, we need to use the pool water treatment flocculant to flocculate and precipitate the tiny debris in the pool water, and then in the bottom of the pool suction dirt. Pool water treatment flocculation in the pool cleaning process plays a key role.
Water treatment flocculant is also known as water treatment sedimentation agent, water treatment coagulant. Commonly used flocculants include:
Inorganic flocculants: aluminum sulfate, aluminum chloride, ferric sulfate, ferric chloride, polymeric aluminum chloride, polyferric sulfate, etc;
Organic polymer flocculants: polyacrylamide, Poly(Dimethyl diallyl ammonium Chloride), etc;
Pool water treatment usually used agents include: polymeric aluminum chloride, polyacrylamide flocculant.
Polymeric aluminum chloride as a pool water treatment flocculant, in water purification in the form of colloidal form, has a large specific surface and adsorption capacity, can precipitate many anti-charged colloidal particles from the water, and then play a purification role. Of course, the formation of colloidal particles is also based on a certain degree of hydrolytic polymerization of polymeric aluminum chloride.
Operation method
Polymeric aluminum chloride as a swimming pool water treatment flocculant for the pool water precipitation, the operation method and the use of the environment is many swimming pool managers do water treatment flocculation encountered when the difficulty. Below we explain in detail how to use polymeric aluminum chloride flocculation of swimming pools.
Water treatment flocculant feeding time: generally arranged in the evening closing time of the pool water flocculation, and after the need for static sedimentation time is generally not less than 6 hours, and then the pool should be suction pollution.
pH control: the most suitable pH range of polymeric aluminum chloride is 7.5-8.5, in the alkaline environment, it can give full play to its hydroxyl bridging effect and accelerate the coagulation and sedimentation effect, so the pH value of the pool water should be checked and adjusted before the flocculant is added.
The amount of flocculant should be calculated according to the total volume of the pool, and the concentration of flocculant should be 5-10mg/L. Depending on the pollution condition of the pool, the flocculant can be added 1-2 times a week.
Dosing method: 5-10KG per 1000 cubic meters of water. When using, according to the ratio of solid polymeric aluminum chloride 1 part: 3 parts of water first mixed and dissolved, and then diluted to 2-3% solution with water can be sprinkled into the pool.
Caution
Finally, pay attention to the rainy weather do not add water treatment flocculant, because the water can not stand still, will affect the flocculation effect.
