  • Treatment of textile wastewater using adsorption

    2021-1-1 · When this textile wastewater is directly allowed in the soil, it blocks the pores of the soil, thereby affecting the soil fertility . This causes the soil to decrease water absorbency and makes the texture harder, which causes difficulty for root penetration . The effluent released in the drainage system corrodes and encrusts drainage pipes.
