Waste water quality and reuse in irrigation in Kuwait using microfiltration technology in treatment

Micro filtration (MF) unit has been tested in Kuwait Institute for Scientific Research to treat the secondary wastewater effeulant from Riqqa wastewater treatment plant. This test shows that the MF unit is reliable and very effective in removing wastewater impurities. Chemical analysis result revealed that the MF system has significantly improved the quality of the effluent. There was a consistent reduction in biological oxygen demand (BOD), Chemical oxygen demand (COD), Total bacterial count (TBC) and total suspended solid (TSS). This paper study the suitability of the filtrate water from MF unit for irrigation purpose, compare the quality of MF product water with the standards for irrigation in Kuwait and other organization. The comparison is based on calculation sodium absorption ratio (SAR), residual sodium carbonate (RSC), adjusted SAR, sodium hazards (SSP), and measured parameters such as the electrical conductivity (EC), chloride, calcium and potassium concentration, total suspended solids, sodium, trace metal analysis and other parameters of health significance. The result of the study revealed that the quality of the wastewater treated by MF unit was suitable for irrigation with low potential problems.
