The solution of environmental protection technology is feasible

The idea of ​​a technology solution to protect the environment for the problem of water treatment from water sources of rivers, lakes and marshes with simple cheap tools and equipment of the chief engineer Tran Ngoc Du has been given the chance. public information agency. This is a highly feasible topic.

The working principle of water filtration equipment is interruption according to the water demand of each household with the corresponding number of people in a day and night is very practical.

Stemming from the idea of ​​serving the working people in the countryside, with a compact, portable device, but fully implementing the steps required for a process of water treatment - living level, to adapt to the conditions, investment capital for each poor family, and be completely satisfied, with the water use needs of each subject in terms of quality and volume of water to be consumed in a day and night, including the aesthetics of technological equipment upon request depending on each family, residential cluster or urban area to establish a treatment facility to provide clean water with a large capacity required for a day and night This is the key idea of ​​a technological solution for super-fast water treatment.

Can summarize the process of super-fast water treatment in the following stages: Water source from rivers, lakes, lagoons . is directed into the device (by hand, or by direct pump) to conduct the flocculation process , depositing sludge, sand, mechanical residues, organic impurities, algae and algae, iron salts Fe3 +, Mg2 + . separated from water, made in water after only 2-5 minutes with PAA / 05 . With disinfecting chemicals for water that is allowed to be used as Clorin (Chloramine), violet or oxygen . according to permitted standards, we will disinfect the filtered water; sediment after being separated from water, is deposited to the bottom of the water treatment device. The water is completely discolored and becomes safe to use; Next is the fine filtering process, which is performed in the second compartment of the device.

Filtering is done through a combination of filter materials (VLL). Traditional VLL combined with activated carbon. Manganese dioxide catalytic particles MnO2 . The total volume of materials accounts for approximately 10% by volume of filter barrel size. Activated carbon is a famous filter material, a type of filter material that is very effective in treating environmental pollution for industrial and domestic waste water sources.

Clean water is removed from the clean water valve after it has been passed through the VLL block, the sediment is discharged through the discharge valve at the bottom of the filter device. The source water after settling, separating the residue from the sediment compartment of the filter barrel is passed through the fine filtering chamber with the VLL block thanks to intermediate valve. Super-fast water treatment composition PAA / 05 used in the project is a combination made from a polymer (Poliacrylamit / CH ₂ CHCONH ₂ ), PAA / 05 acts as a coagulant, multi-electrolyte. The glass has a very high ion separation activity to neutralize the charge of soil adhesives and impurities (they are generally organic and other organic substances dissolved into water sources).

With a number of different minerals that are easy to exploit, easy to process and available in our country, these characteristic minerals act as agglomerates and fast aggregates. Thanks to this, the mechanism of super-fast agglomeration process has been created, which has very high efficiency for many different polluted water sources.

With a content of not more than 30g PAA / 05 for a volume of source water to be treated, low cost, not exceeding 2,000 VND / m3 including equipment depreciation. Coagulation aids and coagulants in PAA / 05 preparations are universal water treatment products, completely non-toxic. The composition is introduced as an intermediate, bridged and incorporated into the sludge, which will be pulled out immediately after 2-5 minutes with sediment at the bottom of the filter holder.

About technology equipment: It is a device that is easy to make from materials such as: Stainless steel, galvanized steel sheet, PVC plastic and porcelain. The device is modeled according to capacity by types of sizes 100, 150, 200, 300, 400, 500l . depending on the water demand of each family in the community community. In addition PAA / 05 preparations have a wide range of applications for many domestic, industrial, medical waste water sources, livestock, poultry and aquaculture . such as shrimp and fish.
