"Effects on the lysimeter facility monitoring immediately after nine months of Procedure indicated significant attenuation of vital pollutants during the unsaturated zone of great sand soils. Biochemical oxygen need (BOD) reductions were in surplus of 98 p.c, full organic carbon (TOC) reductions were being much more than 90 percent. Full Kjeldahl nitrogen (TKN) reductions were in extra of ninety seven %. Nitrate-nitrogen (NO3-N) produced from nitrification was transported to both of those the two and 4 foot depths, but at lower concentrations than the total nitrogen placed on the soil, indicating some reduction of full nitrogen concentrations inside the soil program.
Beautiful contemporary style The HKTS 16BQ/WQ procedure signifies a décor-pleasant enhance to any leisure center or home theater.
