Thermax installs a fully automated water treatment plant in Bangladesh
Thermax has commissioned a water treatment plant with a capacity of three million litre per day (150 m3 / hour). The fully automatic plant is for a global beverage company’s manufacturing facility at Mymensingh, Bangladesh, about 90 km from Dhaka.
This comprehensive project treats the inlet water (drawn from the ground) through a combination of systems for aeration, filtration and ultrafiltration. These help in the removal of TDS (total dissolved solids) and iron from the water. The system also comprises dealkaliser, softening and double stage reverse osmosis (RO) plants and a backwash recovery system.
In water treatment systems,the backwash process that cleans up the filters at specific intervals, essential for optimum performance, consumes large quantities of water. The WWS team has designed a backwash recovery process to recycle 87% of the water. The wastewater reject from the RO plants also is recycled. As a result of such integrated design and automation (operated through SCADA offered with PLC) the plant, compared to conventional ones, operates at an overall 5% higher efficiency.
Through an appreciation letter, the customer expressed his satisfaction with the performance of the Thermax plant. It is now a reference project for peer companies in Bangladesh. Thermax has also supplied two Shellmax boilers with BOP to the same customer.
