Natural Coagulants

Natural Coagulants

Developed innovation description

In Servyeco we have developed a range of natural based coagulants. These coagulants are obtained from extracts of certain trees, are presented in liquid form have a polymeric structure of polyphenols, are coagulants used in waste water with optimal results. Its chemical structure presents multiple polyhydroxyphenyl groups, which have a high affinity for the proteins, metal ions and other macromolecules such as polysaccharides. They also have antimicrobial properties, thus reducing or eliminating the content of pathogenic microorganisms capable of causing disease.

 

Our natural based coagulants perform in industrial and urban wastewater treatment plants in a similar way the synthetic coagulants, agglomerating suspended particles containing in raw water, facilitating sedimentation and reducing turbidity. However, they have great advantages in front of traditional treatments.

 

These coagulants are efficient both sedimentation (settling) and flotation systems very common in industrial and urban wastewater treatment plants. Nevertheless, when the content of oils and fats is very high, its efficiency is optimal in flotation systems, for example in water from food processing, chemical, petrochemical...

 

 

Application

 

•          Selection

In general natural coagulants ECOTAN series are efficient both sedimentation (settling) and flotation systems very common in industrial and urban wastewater treatment plants. However, when the content of oils and fats is very high, its efficiency is optimal in flotation systems (water food processing, chemical, petrochemical...). Moreover, the ECOTAN series not modify the conductivity of the treated wastewater. For this reason, these products are highly recommended in recirculating water where the ion concentration may increase over time (cutting, grinding or polishing of ceramic process, glass, metals...). Also, highlight that they have antimicrobial properties, so they are recommended in treatment systems where the pathogenic microorganisms capable of causing disease in people have to be reduce.

 

•          Dosage

These liquid products can be dosed either directly or previously diluted, without modifying effectiveness, for dilution is recommendable to keep stirring and for application it is used dosing pumps with the necessary flow.

•          Control

The natural coagulants of ECOTAN series effectiveness is distinguished in a very visual way due to turbidity values obtained in the clarified of treated water. The more matter, dissolved and suspended, is destabilized because of coagulant action, the less turbidity values are obtained for these clarified. Furthermore, the floc consistency increases with product effectiveness, so that a high effectiveness of the products gives as a result a smaller sludge volume and easily dewatering because the sludge obtained have a high content of solids. Later analytical control of treated water of dissolved salts, metals, turbidity, suspended solids and chemical oxygen demand help us control the appropriate treatment dose.

 

Benefits

 

•          Technical

The ECOTAN series are natural products, for that reason, they have better improvements than other traditional coagulants for water treatment such as an efficiency increase, not pH dependence and not increase in conductivity. In fact, the natural-based coagulants are dissolved in water, without reacting with it, having coagulant optimum efficiency over a wide pH range, only limited by the stability of the product. Moreover, the ECOTAN series not modify treated water conductivity. For this reason, these products are highly recommended in recirculating water where the ion concentration may increase over time. Thus, protects against corrosion of metallic parts.

In general natural coagulants ECOTAN series are efficient both sedimentation and flotation systems in industrial and urban wastewater treatment plants. However, when the content of oils and fats is very high, its efficiency is optimal in flotation systems. Being a natural coagulant handling is safer for people, favouring biological processes and biodegradability of sludge allows its use in agriculture by not providing metals.

 

•          Economic

The technical advantages of natural coagulant in wastewater treatment plants produce a high number of economic advantages. By not increasing the effluent conductivity, in water recycling processes, the corrosion of the facilities will be avoided, so that the maintenance is much inexpensive. Its higher coagulant efficiency allows more active colloidal aggregation and more consistent floc than with traditional reagents, so that the necessary quantity of product is reduced and also the associated costs. Furthermore, due to the more compact floc formation, is greatly reduced or completely eliminated the use of flocculants, and can achieve an effective precipitation of floc formed in the first purification stage and avoiding the extra costs due to the use of flocculant and the use of neutralizing agents is also avoid (calcium hydroxide and sodium hydroxide). Finally, add that smaller volumes of sludge are obtained and less toxic sludge are generated so the costs associated to the sludge handling are highly reduced.
