Wastewater treatment during gelatin production is a process often used to remove contaminants from wastewater. The wastewater treatment process in gelatin production facilities may vary depending on the characteristics of the facility and local regulations. However, it generally includes the following steps:
Pre-Treatment: Pre-treatment is done to remove large particles and floating substances in the wastewater. This is usually accomplished using physical filtration processes such as strainers, sieves or settling tanks.
Chemical Coagulation / Flocculation: Chemical coagulants and flocculants are used to remove impurities in wastewater. Coagulants allow the particles in the wastewater to come together to form large flocs. Flocculants support the formation of these flocs and increase their size. These flocs can then be removed by precipitation or filtration.
Settlement: A settling tank is used to settle and settle the flocs formed as a result of chemical coagulation and flocculation. As the flocs sink down under the effect of gravity, the cleaned water collects on the surface.
Filtration: After settling, a filtration step can be applied to further purify the clarified water. Filtration removes fine particles, sludge and other contaminants from the water. Sand filters, carbon filters or membrane filtration systems can be used in this step.
Disinfection: Disinfection is applied to purify the purified water from microorganisms. This step ensures that the water to be used for gelatin production is made safe for health. Disinfection can usually be done by methods such as chlorination, ultraviolet (UV) rays or ozonation.
Recovery: Some gelatin production facilities may also have advanced treatment steps to recover and reuse the treated water. These steps aim to recover the minerals, nutrients or other valuable components in the purified water.
Wastewater treatment during gelatin production ensures that the plant operates in accordance with local regulations and minimizes adverse effects on the environment. This process is important for environmental sustainability and resource efficiency.
