Join us in shaping a cleaner, brighter future for the next generations.
For the largest steel producer in the country, Advent provided a 16 MLD Zero Liquid Discharge Plant at its green field project in Orissa, offering 95% recovery through RO for a feed characterized by high hardness and silica level, amongst other impurities. The project incorporates high lime‐soda softening & dolomite treatment, MBR‐based Sewage Treatment, Multi‐stage RO for Desalination and Multiple‐effect Evaporator for disposal of RO Reject. The project uses TMF as pre-treatment to RO as well as for recycling of low TDS stream. Along with blow-downs and neutralized effluent streams, one of the major feed streams to this ZLD system is the effluent from Coke-Oven ETP, also executed by Advent Envirocare. The Coke-oven ETP handles an exotic effluent containing very high levels of phenol, COD, colour, ammonia, thiocyanate, cyanide and colour and treats them to the statutory norms, followed by subsequent water recovery in ZLD supplied by Advent.
An agrochemicals giant opted for Advent Envirocare’s Brine Concentrator to minimize the operating cost of Multiple Effect Evaporator for a process stream having 4.3% TDS and about 3000 ppm COD. The Brine Concentrator was successfully installed to concentrate 200 m3/day feed stream to 16.2%, reducing the MEE feed by upto 74%. The Brine Concentrator is based on the concepts of Forward Osmosis and the concentration was achieved at pressures lower than 70 bar.
Taking up their fifth ETP project for this dyes manufacturing major based out of Surat, Advent Envirocare serviced the three-decade relationship with an expansion project of additional 6 MLD Effluent Treatment Plant besides the old 4.8 MLD facility that Advent Envirocare provided before 15 years. The new facility involves biological nitrification-denitrification system for this high-strength wastewater with low biodegradability. Tertiary PSF and ACF takes care of further reduction of COD and the master plan includes a membrane-based tertiary treatment set-up for future.
Advent Envirocare undertook a major upgradation at the existing Common Effluent Treatment Plants catering to textile processing units of Pali in Rajasthan. The project involved Tilted Plate Separator for removal of oil & suspended solids, additional Equalization Tanks, mechanized Chemical Dosing Systems, replacement of existing Aeration System and mechanical dewatering using Decanter Centrifuges. The unit at Mandia Road treated 13.6 MLD flow while the one at Punayta Road treated 9.1 MLD flow. The upgradation was done on turnkey basis within 15 months. The project also involved Operation & Maintenance for 12 months.
This pharma giant opted for a “vertical” ETP to minimize the footprint to save on space as well as to minimize seepages. The ETP is a three‐tier structure with Equalization Tank on top, Primary Treatment in middle and Secondary Treatment at ground level. Tertiary Treatment and Filter Press for Sludge dewatering are also located at ground level. The ETP has a capacity of 160 m3/day and involves two‐stage biological treatment because of the high organic load in manufacturing bulk‐drugs (API). The entire plant, including laboratory and control room, is accommodated in a space of just 200 m2.
This pharmaceutical major wanted a reliable and cost-effective solution to handle high COD effluent for its expansion at its API unit in Dahej SEZ. The wastewater flow was 150 KLD with a COD of 15000 mg/L, with the target to achieve disposal standard of 250 mg/L. Advent Envirocare took up this challenging project and constructed the plant during the pandemic, successfully meeting the desired norms. The project involves two-stage biological treatment using Advent Envirocare’s proprietary AIS technology, followed by tertiary filters.
