Special Coagulants

Fluorides removal. ECOFLUOR

 

What are they?

ECOFLUOR Series is based on coagulation aid liquid products, focused on removal fluorides during chemical treatments, mainly in settling processes. In several industrial sectors, high value of fluoride content is detected in the wastewater and can not be removed with conventional chemicals. Servyeco has developed a new and innovative range of products which reduce fluoride content down to the technical and legal requirements. These products are widely used in the metal-mechanic sector.

 

Metals Removal. ADIMET

 

What are they?

ADIMET Series products have been designed to act as high efficiency precipitating metals agents. The ADIMET Series precipitates metals, such as copper, nickel, zinc, chromium, cadmium, silver, lead, iron and mercury, through chelating and complexing processes. These products provide a proper precipitation of the contaminating metals from wastewater.

The ADIMET products are applied when conventional physicochemical treatments, like formation of metallic hydroxides, are not able to remove the metals present in the wastewater. They are often used in the industrial wastewater treatment plants of diverse sectors with high concentration of metals as metal-mechanical industry or metal mining, among others.

 

Advantajes

  • The products of ADIMET Series present a partially stoichiometric reaction with soluble heavy metals in a wide range of pH and temperature.
  • Quelating activity is based on the presence of a sulfur derivative, dithiocarbamates, and the synergy with other organic additives included in the product.
  • For that reason, both chemical processes must be taken into account and the removal efficiency of multivalent metallic ions is very high.
  • Additionally, ADIMET Series products generate a smaller volume of sludge easily dewatering.
  • ADIMET Series products form an insoluble precipitate with multivalent metals, both complexed and chelated. This precipitate can be removed by filtration to management or recovery.
  • Sludge removal is an important factor to take into account in precipitating metals from wastewater. These products produce lower sludge weight and much smaller volume than the standard treatments with hydroxide or sulfide precipitation. Thus, the costs derived from sludge management are considerably reduced.
  • Because of its removal efficiency in a wide range of pH and temperature, the ADIMET Series products entail cost benefits associated with the doses and types of chemicals used, ensuring proper treatment of wastewater and avoiding possible additional management costs.

 

Application

Selection: ADIMET Series products are used in order to efficiently precipitate multivalent metal ions in wastewater (copper, nickel, zinc, chromium, cadmium, silver, lead, iron or mercury) through chelating and complexing processes.

Dosage: The liquid product can be applied directly to the wastewater or previously diluted. In both cases, the complexing/chelating efficiency is similar. It is highly recommended the later dosage of a polyacrylamide based flocculant in order to improve the floc formation.

Control: In order to determine the efficiency of metal pollutants removal, an equipment of analytical testing at laboratory scale is required.

This system should be capable of determining the concentration (ppm) of problematic metal ions present in the wastewater and compare it with the concentration in treated water. Additionally, the redox potential is a control agent indicating the residual portion of the product, compared to the initial dose used..

 

Multifunctional Products. SOLTEC

 

What are they?

SOLTEC Series products are multifunctional solid coagulants for wastewater treatment in batch process. These products are highly recommended when the content of oil, grease and surfactants in the wastewater is very high. They are usually dosed in industrial wastewater treatment with low flows in continuous or in batch treatments. With a single product, water is purified and ready for disposal or reuse without the use of any other chemical like coagulants, flocculants or neutralizing agents.

 

Application

Selection: The products of the SOLTEC Series are used for industrial wastewater treatment from different sectors like ceramics, paper, cardboard or textile. With a single multifunctional solid product water is efficiently treated. Additionally, these coagulants are mainly effective when the content of oil, grease and surfactants in the wastewater is very high
