Effluent is a liquid waste (wastewater) generated by factories, hotels, vehicle service centers and other commercial business units. As it contains high level of BOD, COD, TSS and TDS, it puts negative effect on the water and soil. The high level of BOD significantly decreases dissolved oxygen (DO) level; hence,
it puts fresh water resources in danger. In today’s scenario it is imperative to treat industrial wastewater to a level where it can be reused safely or drain out without affecting the environment. CPCB and other statuary bodies have set some guidelines for wastewater that every effluent treatment plant must follow.
Effluent Treatment Process Explained
Industrial wastewater (effluent) is treated in a number of ways; the level of treatment decides which is appropriate. Basically there are four steps: Preliminary, Primary, Secondary and Tertiary. A3S Enviro providing Packaged ETP with below Process:
- Preliminary Treatment: Screening, grit and oil removal are done at preliminary treatment process.
- Primary Treatment: Primary treatment involves removal of suspended solids up to 50% and reducing BOD level up to 30%.
- Secondary Treatment: This is sometimes referred to Biological Treatment. Through biological processes, dissolved and suspended organic wastes are converted to more stable solids and removed by settling.
- Tertiary Treatment: It is the final stage which involves physical, chemical and biological processes to remove residual suspended solids and dissolved solids.
A3S Enviro Manufacturer and install packaged treatment plants to generate high quality treated wastewater, which is safely released into the river or re-used at the same site.
Our packaged ETP plants are pre-engineered systems designed for on-site usage or commercial or industrial applications, where treatment of low quantities of effluent required.
Available in 5 KLD to 200 KLD capacities, these units are compact in size and occupy very less space and require very low operational cost. As required,
our packaged etp plant units can be designed as skid mounted or containerized. The most important advantage of wastewater treatment container is its movability; a containerized ETP is fabricated at our factory and transported to the site, where it is used. Construction site, disaster areas, civil and military base camps are fewer examples, where our packaged wastewater treatment plants are mostly used.
Common Effluent Treatment Plant (CETP)
Especially designed for industrial estates and SEZs, where establishment of individual effluent treatment facility is not possible; concept of Common Effluent Treatment Plant (CETP) comes into effect. It is a kind of waste management, where small and medium sized industries jointly treat their wastewater affordably by installing such an Effluent Treatment Plant, which is common for every unit. Installation of ETP for single manufacturing unit is not possible due to budget problem and limited area allotment to each unit; therefore, a CETP is a best option which not only protects water environment but also divides the investment and operational costs. Wastewater pipelines from every manufacturing unit are connected to the CETP for treatment.
We design, manufacture, erect and commission effluent treatment plant (ETP) for industrial and commercial units at economical price. Civil and allied works are optional and can also be done if required by client. The completed plant is handed over to the client after conducting successful performance and acceptance tests. Through training is also provided to the operators of ETP. If required, we also provide our own operators at client’s site for operation and maintenance of effluent treatment plant.
We have experienced engineering team, which conducts all designing, erection and commissioning at client’s site. Our company follows all safety policy and plant safety rules under factories act. A3S Enviro construct CETP Plant as per Guideline of PCB & NGT . Range Starting from 300 KLD 10 MLD
