METHOD TO IMPROVE COAGULATION PROCESS IN DYE WASTEWATER TREATMENT

Abstract

Method to improve coagulation process in dye wastewater treatment ABSTRACT The dye industry requires specialized skills and plays a crucial role in the economies of many countries. One of the most recognized methods for removing pollutants is coagulation, which is favored for its simplicity, cost-effectiveness, and the recyclability of adsorbents. This study investigates the use of Carica papaya as a coagulant for treating dye wastewater. Findings indicate that Carica papaya is effective in removing solids from wastewater. The aim of this research is to evaluate the effectiveness of coagulants derived from Hibiscus rosa and Carica papaya in reducing turbidity, adjusting pH, and altering color in dye wastewater.

Method to improve coagulation process in dye wastewater treatment

PREAMBLE TO THE DESCRPTION

THE FIELD OF INVENTION
The present disclosure associates with the method to improve the dye wastewater treatment by coagulation process.

BACKGROUND OF THE INVENTION
Various treatment methods were adopted to remove the organics and inorganics in the wastewater. The most well-known method for removing pollutants is coagulation, due to its simple operation, afford ability, and recyclable nature of the adsorbents. In the coagulation process, a coagulant is added along with rapid mixing to destabilize the non-settleable particles and to initiate their aggregation by neutralizing their electrostatic repulsive forces. Whereas flocculation is the process of aggregation of destabilized particles, through gentle agitation that leads to the formation of larger particles called flocs. The primary treatment will be beneficial in enhancing the efficiency of any treatment plant as it reduces the significant amount of pollutant prior to reaching the secondary treatment. The primary treatment generally reduces 90-98% of settleable solids and 60-80% of suspended solids along with 30- 50% oxygen demand from the waste and hence reduces the load of other treatment subunits. Coagulation is invariably achieved by using different metal salts that hydrolyses in water. These metal salts adsorb the colloidal particles and form larger flocs. These flocs, therefore, can easily be settled down after becoming larger particles under the effect of gravity and later known as settled sludge. This study presents the findings of wastewater analyses using Carica papaya coagulation for pollutants removal, turbidity, and pH. Colors are typically used to shade items in areas such as texture, plastic, paper, clinical, and magnificence items. In recent years, nanomaterials were used in water .and wastewater pollutant removal.

SUMMARY OF THE INVENTION
Method to improve coagulation process in dye wastewater treatment using Carica papaya. Using Carica papaya, the coagulation process is enhanced with low sludge production, which is biodegardabale.

Method to improve coagulation process in dye wastewater treatment
COMPLETE SPECIFICATION

Specifications
• Carica Papaya was peeled using a special knife, sliced into small pieces, and then stored at
4°C until extraction.

• 1.0 kg of epicarp were extracted with 0.2 liters of ethyl alcohol; 1 gm of antioxidant and 10 gms of calcium carbonate were added to prevent oxidation and acidic isomerization.

• During the coagulation process, Carica papaya was taken as 0.3 - 5.0 mg/L.

• Carica papaya was added to wastewater at fixed concentrations, agitated rapidly for one minute at 100 rpm, slowly for ten minutes at 30 rpm, and then allowed to settle for fifteen minutes.

DESCRIPTION
The studies were conducted at different rpms ranging from 110 to 160 in order to examine the effects of the coagulation process. Carica Papaya settle the solids in two minutes at 140 rpm. The effect of pH on the removal of turbidity was investigated by adjusting the pH from 6 to 12.5 in the test mixture. The results showed that the removal by Carica papaya, which is approximately 84%, is obtained at the novel coagulant dose of 20 ml/L of Carica Papaya when the pH is 6.1, and that beyond this point, the percent removal becomes more or less constant.

CLAIM
We Claim

1. Claim: Carica papaya improves the treatment efficiency.

2. Claim: Carica papaya, a natural coagulant produces biodegradable sludge after treatment which does not produce any toxic to the environment.

3. Claim: After the coagulation process, pH value for the treated water is 6.5.

4. Claim: The results showed a maximum pollutant removal of 80% by using Carica papaya, as coagulant.
