US 2011/0253522 A1 · METHOD AND SYSTEM FOR PURIFYING LIQUID USING WASTE HEAT

Abstract

A method and system for purifying liquid using waste heat is provided. Initially, a liquid is mixed with an anti-sealant agent in a first filtering unit to form a liquid mixture. Thereafter, the liquid mixture is filtered in the first filtering unit to separate foreign objects from the liquid mixture. Subsequently, the liquid mixture is heated in a pipe arrangement connecting the first filtering unit and one or more second filtering units to generate steam. The steam obtained from the heated liquid mixture is then purified in the one or more second filtering units. Thereafter, the purified steam is condensed in the pipe arrangement to obtain the purified liquid.

Dependent claims

A liquid purification system comprising:

a first filtering unit capable of mixing a liquid and an anti-scalant agent there within to form a liquid mixture and filtering the liquid mixture, wherein the liquid comprises at least one of a sewage water and a saline water and the anti-scalant agent comprises at least one of a nitrate, a glycerin and a salt;
at least one second filtering unit, wherein a second filtering unit of the at least one second filtering unit filters the liquid mixture;
and
a pipe arrangement for connecting the first filtering unit and the at least one second filtering unit, the pipe arrangement capable of circulating the liquid mixture in the liquid purification system, wherein the pipe arrangement receives heat from at least one heat source for heating the liquid mixture to obtain a purified liquid from the liquid mixture.
