Summary of the technology
This invention develops a process for the removal of zinc from waters, namely, rainwater, resorting to a low-cost biomaterial, resulting in water suitable for use in buildings. The process comprises three steps: (a) preparation of the adsorbent material; (b) removal of zinc from referred water; (c) removal of adsorbent material from the water, which is ready to use. The technology is simple, convenient, cheap and of easy application.
Many of the techniques currently applied for the removal of heavy metals from water, such as zinc, are based on methods that require sample preparation and require potentially hazardous materials. Such methodologies are costly and require the application of specific equipment.
The present invention provides a method for the removal of zinc from rainwater based on the use of a biomaterial as adsorbent. The proposed methodology does not require preparation of the water, is cheap, and is suitable for use in buildings, either in residences or in industries. The used biomaterial may be reused either for agricultural and industrial purposes.
DOES NOT REQUIRE SAMPLE PREPARATION
ENVIRONMENTALLY FRIENDLY: uses a common biomaterial, which can be reused in other applications.
This method can be used for rainwater treatment to be used in buildings:
