What is special about ROTO septic tank? Advantages and exclusive technology from ROTO

Production of septic tanks with 100% Automatic Rotation Technology

ROTOs manufacturing process comes from Rotational Molding Bi-axial Technology. Mixture method to mix fuel in liquid form by high temperature. The auxiliary materials are ground into a fine powder. Therefore, the output product will have outstanding advantages compared to the dry mixing method such as:

Liquefaction of primary resin and color helps resin and color to bond firmly, increase durability, gloss and contribute to anti-light penetration, preventing the formation of moss.
UV is the main ingredient that must be liquefied with the above mixture to help prevent ultraviolet rays from entering the tub
Colorants to form a mixture of secondary materials to produce a beautiful, long-lasting and aging product with a shelf life of over 60 years.

All production processes are controlled by an automatic control system (PLC): the elements of temperature, rotational speed, etc. according to each product volume are programmed and controlled to achieve the desired level. optimized by machining. Current technology ROTOMOUNDING BI-AXIAL. To be able to put on the market, it also has to go through rigorous product quality checks. Finally, finish the exterior and package the product. ROTOs septic tank is trusted by contractors, used for townhouses, stilts, garden houses, ...

100% anti-clogging reverse filter system: inside there is a biological filter compartment containing a substrate to help microorganisms grow to form a natural biological filter. The reverse filtration system helps the intermediates to be pushed with the continuous inlet water stream to prevent block formation like traditional tanks leading to clogging.

ROTO septic tank for wastewater meets B standard

Standard B wastewater is regulated to have all the indicators such as: arsenic, lead, suspended solids, chromium, chlorine, copper, zinc, mineral grease, animal and vegetable oils, cadmium, manganese, nickel, tin , iron, phosphorus, mercury, ammonia, cyanide... For HUMAN domestic wastewater, the index of SS, BOD is the most important. Because these indicators will decide that the wastewater falls within the scope of class B wastewater standards.

SS: Suspended solids (SS) present in the waste and part of the resulting decomposers are removed according to the ROTO method. CONTAINER (bearing frame to help contain and limit the flow of water inside the tank body to help SS decompose more efficiently) and BIOGRAPHY FILTER is a biofilm created from the operation process. of microorganisms to help filter the SS.
BOD: ROTOs anaerobic filtration method works best in hypoxic conditions so a 70% response is always guaranteed for the first 5 days.

Why does ROTO use LLPDE for septic tanks?

For ROTO products, LLDPE (Linear Low Density Polyethylene) plastic is considered the best quality and safest. In terms of characteristics, they have a considerable number of short branches. Because it has more and shorter branches, its chains can slide into each other when stretched out without entanglement like LPDE has long branch chains that can entangle each other. This gives LLDPE higher tensile strength and greater resistance to impact and puncture than LDPE. The density falls in the range of 0.91-0.94g/cm3.

Durability (1 uniform layer): Only 1 layer of homogeneous primary plastic completely overcomes the uneven expansion of multi-layer plastic which is one of the causes of tank breakage, withstands impacts from the external environment. such as: Weather (low humidity, high temperature, underground, hot dry...) and impact (strong impact, scratches). LLDPEs highly branched network makes the ROTO septic tank resistant to strong environmental and external influences over a long period of time.
Safety: Because it does not corrode or dissolve with a mixture of wastewater, soil contaminated with alum, salt) durable over time to help protect the living environment, ensuring health and safety.
Superior bearing frame system: Anti-breakage helps to distribute pressure evenly on the tank body and increase the efficiency of waste storage and sedimentation. CONTAINER (bearing frame to help contain and limit the flow of water inside the tank body to help SS decompose more efficiently) and BIOGRAPHY FILTER is a biofilm created from the operation process. of microorganisms to help filter SS again.

Compared to other competitors in the tank industry, ROTOs products are always durable because we do not use LPDE series PE plastic, which is hard but brittle. Instead, the use of the LLPDE line of PE plastic gives outstanding quality but is always affordable. In addition, the tiny plastic particles cannot be dissolved in water, so customers can be assured and satisfied with their health.

ROTO septic tank meets strict standards of international organizations

ROTO septic tank is made from 100% virgin plastic - extracted from petroleum ore, without impurities. In addition, ROTO septic tanks also meet strict standards on safety and hygiene of domestic water sources. Therefore, international organizations have always trusted and used ROTO and ROTO septic tank products and have accompanied international organizations such as: CARE, Save the Children, Novaland, Worldbank, Association, ...
