Modular assembly to treat water in polluted stagnant or lagoons, ponds and rivers

摘要

An assembly cleans up stagnant surface water with the assistance of chemical agents, mixing assemblies, dosing pumps, mixers and inoculation stations. The assembly especially incorporates a variable length fluid residence trough at whose inlet is an assembly (1-5) to generate a suspension. The discharge is to a further suspension generation assembly (7-12). An assembly cleans up stagnant surface water with the assistance of chemical agents, mixing assemblies, dosing pumps, mixers and inoculation stations. The assembly especially incorporates a variable length fluid residence trough at whose inlet is an assembly (1-5) to generate a suspension. The discharge is to a further suspension generation assembly (7-12). The chemical composition of the first suspension differs chemically from the second. The first section discharges to a mixer (13) and then to a second residence trough (14) of variable length, or directly to the water to be treated. The mixer (13) combines the first suspension with the second to form a highly adsorptive flocculating agent. The residence troughs (6, 14) dimensions of cross sectional area and length are determined by the water flow rate which achieves a given time interval between the admixture of first and second additives. The modular assembly may incorporate both fixed and float-mounted aggregate units.
