Method For Treating Agricultural Run Off Water For Boiler Make Up Water
Abstract: This invention relates to a method for treating agricultural run-off water to produce make-up and process water for boilers, comprising the steps of; storing of agricultural run-off water in a storage space; supplying a predetermined quantity of the water from the storage space in a first pretreatment stage (01), a set of chemicals (07) being injected to the predetermined quantity of water before being delivered to the first pretreatment stage (01); delivering the water after the first pretreatment to a second pretreatment stage (02) preceded by dosing of coagulants (08); delivering the water after the second pretreatment to a third pretreatment stage (03) to generate a conditioned pretreated water; supplying the conditioned pretreated water to a first Reverse Osmosis (RO) stage (04), the concentrate from the first RO-stage (04) being recovered for use in applications like gardening and flushing out; supplying the lower dissolved solids water from the first RO-stage (04) to a second RO- stage (05), the brine from the second RO-stage (05) being refused to enhance the overall system recovery; and delivering the permeate water having very low dissolved solids to a demineralization plant (06) to produce the boiler-feed water.
